Environmentally friendly pretreatment of double refractory gold ores (DRGO) to improve gold recovery without emitting pollutant gas is challenging. Sequential biotreatment, including iron-oxidizing microorganisms to decompose sulfides, followed by the enzymatic decomposition of carbonaceous matter, was recently developed. The effect of acid washing by 1 M HCl for 24 h between two bioprocesses was evaluated using a real double refractory gold ore from the Syama mines, Mali, which includes 24 g/t of Au and 5.27 wt% of carbon with a relatively higher graphitic degree. The addition of the acid washing process significantly improved gold recovery by cyanidation to yield to 84.9 ± 0.7% from 64.4 ± 9.2% (n = 2). The positive effects of acid washing can be explained by chemical alteration of carbonaceous matter to facilitate the accessibility for lignin peroxidase (LiP) and manganese peroxidase (MnP) in cell-free spent medium (CFSM), although the agglomeration was enhanced by an acid attack to structural Fe(III) in clay minerals. Sequential treatment of DRGO basically consists of the oxidative dissolution of sulfides and the degradation of carbonaceous matter prior to the extraction of gold; however, the details should be modified depending on the elemental and mineralogical compositions and the graphitic degree of carbonaceous matter.

Double refractory gold ore was sequentially pretreated to oxidize sulfides by thermophilic archaeon Acidianus brierleyi and then to decompose carbonaceous matters using the cell-free spent medium (CFSM) from white-rot fungus Phanerochaete chrysosporium. The pretreatment by A. brierleyi significantly improved the gold recovery from 25% to 77%. Additionally, the crude lignin-degrading enzymes in the CFSM converted the carbonaceous matters into more easily degradable substances, which were removed by alkaline washing, leading to a final gold recovery of 92%. These mineralogical alterations were confirmed by differential thermogravimetric analysis and quantitative evaluation of minerals with scanning electron microscopy. Based on the results, gold grains were mostly liberated after bio-oxidation of sulfides, and in following CFSM treatment, large particles of carbonaceous aluminosilicate were formed from the aggregation of clay minerals, gold grains and with partially decomposed carbonaceous matters acting as binders.

Petroleum products - Abstract
Thermal degradation characteristics of a Japanese oil sand at different heating rates (10, 20, and 30 °C/min), and 30 ml/min air flow rate have been investigated. The kinetic parameters have been calculated based on three stages of weight loss and/or the conversion of the sample. These include, stage 1 (SI): volatilization of moisture content and the light hydrocarbon (20–227 °C), stage 2 (SII): combustion of heavy hydrocarbon (227–527 °C), and stage 3 (SIII): oxidative decomposition of carbonaceous organic matter (502–877 °C). The results showed that the rate of change of the oil sand conversion with time dαdt was affected by the heating rate. The time taken by the system to reach 0.99 conversion was observed as 85, 50, and 35 min at the heating rates of 10, 20, and 30 °C/min, respectively. The frequency factor, A, at SI was between 0.09 and 0.54 min−1, while the activation energy, Ea, was 11.2–12.5 KJmol−1 (the percentage weight loss, Wt, was 0–3.6 %w/w; and the conversion, α, was 0–0.2.). At SII, the values of A and Ea were 2.1–5.5 min−1 and 17.6–19 KJmol−1, respectively (Wt = 3.1–15.88 %w/w; α = 0.17–0.86.). The value of A at SIII was 5.5E11–1.1E13 min−1, while Ea was 160–200 KJmol−1 (Wt = 15.33–17.99 %w/w; and α = 0.84–0.99).

Sequential treatment was applied to carbonaceous Au-Ag-bearing ore concentrate to maximize the Au and Ag recovery. In the preliminary test, the present carbonaceous ore had well liberated and exposed type of gold grains, which are not refractory, but included mainly three types of Ag presented as electrum, hessite (Ag2Te) and Ag-bearing other minerals. Au recovery was ∼100% without any treatment, meanwhile Ag recovery was only 33.3%. The sequential treatment comprises two oxidation steps: (a) mixed culture of iron- and sulfur-oxidizing microorganisms at pH 1.2, followed by (b) cell-free spent medium (CFSM) at pH 4.0 from a white rot-fungus, Phanerochaete chrysosporium, which includes lignin-degrading enzymes. As a result, Ag recovery was 55.5% after the first step and greatly improved to ∼100%, including the dissolved Ag+ concentration in the first step of acid treatment. Although the acidophilic iron-oxidizing microorganisms were inhibited by dissolved Ag+ and Cd2+ ions, the strong acidic conditions dissolved hessite and Ag-bearing oxide minerals. However, the remaining carbonaceous matter acted to sorb Ag(CN)2− in cyanidation, causing the recovery loss. In the next step the lignin-degrading enzymes degraded carbonaceous matter in the ore. This step is necessary to avoid the adsorption of Ag(CN)2− on graphitic carbonaceous matter, leading a mostly perfect recovery of the remaining Ag in the solid residues, without necessity of alkaline washing. The sequential treatment including enzymatic lignin-degrading process was also effective in carbonaceous silver ore avoiding the emission of air pollutants.

Double refractory gold ore (DRGO) not only include ppt levels of gold grains locked in sulfide minerals but also a problematic amount of carbonaceous matter. This causes a significant recovery loss of gold during cyanidation because of the strong affinity of the Au(CN)2− with the carbonaceous matter. Combustion decreases the carbonaceous matter content, but also emits pollutant gases like CO2, SO2 and As2O3. Therefore, environmentally-friendly solutions have been explored by using biotechnology. Due to the very small amount of the above targets in the ore, it is challenging to show evidential changes in solid-phase before and after the biomineral processing of DRGO. This chapter introduces the mineralogical and chemical changes in the various solid residues produced during a sequential biotreatment, consisting of the liberation of gold from sulfides by an iron-oxidizer and decomposition of carbonaceous matter by lignin-degrading enzymes (lignin peroxidase, manganese peroxidase, laccase) secreted from a white rot-fungus, which successfully improved of gold recovery to over 90%. In addition, further development of biotechnology in the recovery of gold from DRGO is addressed.

The pretreatment of carbonaceous material in double refractory gold ores (DRGO) is necessary to decrease preg-robbing of gold and maximize gold recovery. DRGO contains of carbonaceous matter and gold grains encapsulated in sulfide minerals, which typically results in very poor gold recovery. However, there is growing interest in DRGO because some estimates show that it makes up about a third of the total available gold for production by mining. This can be achieved by chemical and biological techniques, however, the chemical techniques like flotation, surface passivation and chemical oxidation have received more extensive study and either have to be retooled or modified to be applied to the carbonaceous matter in the DRGO. In comparison, the biological techniques are relatively unknown with significant gaps in the knowledge about the bio-treatment mechanism, byproducts and avenues for scaling up like bioreactor design. This study reviews the enzymatic pretreatment of DRGO to facilitate gold recovery and minimize reagent consumption. It focuses on the potential for application of oxidative enzymes like lignin peroxidase, manganese peroxidase and laccase to pretreat carbonaceous matter in DRGO with or without an additional step of sulfide oxidation and addresses characterization of byproducts of the enzymatic decomposition. Further, potential bioreactor configurations for the enzymatic decomposition without direct contact of ore with microorganisms are considered, both in terms of understanding the mechanisms within the pretreatment and in terms of application.

Several efforts are made to find various green alternatives for carbonaceous matter (CM) degradation in carbonaceous gold ores. The deleterious effect of CM is observed during cyanidation, where CM adsorbs Au(CN)2- behaving like activated carbon, an effect called pre-robbing. Thus, biotechnological approaches like enzyme degradation of CM to reduce Au(CN)2- adsorption are currently being studied. In the present work, the potential of CM degradation and gold preg-robbing reduction by laccase-mediator system (LMS) oxidation was evaluated using powder activated carbon (PAC) as CM surrogate material through model experiments. Based upon gas chromatography-mass spectrometry (GC-MS) analysis of extracted by-products from bio-treated PAC, LMS treatment after seven days physically and chemically altered the surface of PAC by the reduction of specific surface area and pore volume, the disruption of aromatic moieties into aliphatic compounds, and the formation of oxygen-containing functional groups. Subsequently, under the studied condition, the adsorption capacity of Au(CN)2- on the surface-degraded PAC was dramatically decreased from 46 μmol/g to 7.36 μmol/g. The present findings provide a new outlook of an alternative pre-treatment process of carbonaceous gold ore in mineral processing.

The bio-treatment of double refractory gold ores (DRGO) to reduce preg-robbing needs to account for the heterogeneity of the ore so as to acquire a much more complete picture of the system. To this end, the effects of ferrous ion additives on the degradation of powdered activated carbon (PAC) by cell-free spent medium (CFSM) was studied. Au(CN)2- adsorption and Raman spectrometric results suggest that the ferrous salt could have possibly reacted with some biogenic hydrogen peroxide to aid in the degradation of PAC. The bio-treatment produced mixed solid residues containing some partially degraded aromatic compounds which were soluble in alkaline solutions. Ultimately, biodegradation of PAC using CFSM in the presence of 50 µM FeSO4.7H2O for 7 days followed by washing with 3 mM NaOH reduced Au(CN)2- uptake by 80%.

Carbonaceous matter in refractory gold ore is known to be one of the primary causes of gold recovery loss. Model experiments were conducted to simulate the bio-modification of carbonaceous matter using powdered activated carbon (PAC) as a surrogate and cell-free spent medium (CFSM) of Phanerochaete chrysosporium. The CFSM was used because of the lignin peroxidase and manganese peroxidase secreted by the microbe during its incubation. In the present work, an investigation was conducted to determine the physical and chemical alterations in PAC after enzymatic treatment and its effect on Au(CN)2− uptake. Characterization of the solid residues of PAC by 13C NMR and N2 adsorption after bio-modification revealed that the treatment had decomposed poly-aromatic carbons into aliphatic carbons and also reduced the specific surface area from 1430 m2/g to 697 m2/g in 14 days. As a result, Au(CN)2− uptake decreased from 100% (0.048 mmol/g) to 43% within 12 h primarily due to the enzyme treatment and adsorption of CFSM components. It further decreased to 26% due to surface passivation by bio-chemicals derived from CFSM and/or decomposed aliphatic hydrocarbons from aromatic carbons between 7 days and 14 days. These findings may contribute to efforts to decrease preg-robbing in hydrometallurgical processing of refractory gold ores.

The detailed mechanism behind the bio-decomposition of carbonaceous matter in refractroy goold ore byPhanerocheate chrysosporiumto facilitate improved cyanidation of gold is as yet undersdtood. To gain a better understanding of this mechanism, the present work model experiments using powdery activated carbon (PAC) and cell-free extracts ofP.chrysosporiumto simulate and focus on the biotransformation of carbonaceous matters in refractory gold ores. The results of solid characterization using SEM and XRD indicated a more non-uniform surface and smaller crystal sizes for PAC treaded with cell-free extracts for 72 hours. The significant decomposition of aromatic compounds into aliphatic compounds were observed in13C-NMR and FTIR results for the high ratio of cell-free extract volume to mass of PAC. This results support the theory that one of the fundamental mechanisms behind the bio-decomposition process is aromatic bond cleavage by biomolecules produced byP.chrysosporium.

Natural carbonaceous matter aided the bioleaching of Cu from chalcopyrite concentrates. The oxidative dissolution of chalcopyrite was enhanced more significantly by anthracite than carbonaceous matter in double refractory gold ore (DRGO). This was achieved through Galvanic interactions between the chalcopyrite and natural carbonaceous matter. Measurement of impedance verified that the electro-resistance is smaller in anthracite, which has a greater graphitic degree than carbonaceous matter in DRGO. The electron shuttle between chalcopyrite and the Fe3+ /Fe2+ redox couple was facilitated not only by the amounts of carbonaceous matter but also the degree of graphitization of carbonaceous matter. A higher graphitization degree increased the electron conductivity of the carbonaceous matter to help mediate Cu bioleaching while avoiding direct contact of thermophile cells with refractory copper sulfides.

Sulfides and carbonaceous matter in double refractory gold ore (DRGO) were bio-treated sequentially using an iron-oxidizing archaeon Acidianus brierleyi followed by lignin peroxidase-dominating crude enzymes released from the white-rot fungus Phanerochaete chrysosporium to significantly improve gold recovery from 24% to 92%. Transformation of the carbonaceous matter in the sequential bio-treatment was interpreted with Quantitative Evaluation of Materials by Scanning Electron Microscopy (QEMSCAN), Raman spectroscopy and three-dimensional fluorescence spectrometry. Firstly, microbiological sulfide oxidation did not affect carbonaceous matter but decreased the arsenic content in the solid residue, facilitating the following enzymatic reaction. Next, the crude enzymes predominantly decomposed the defect-bearing graphitic carbon into humic-like substances. The humic-like substances were not completely soluble under pH 4 but were instead retained in the solid residue as a part of a newly formed carbonaceous aluminosilicate (C–Si–Al) phase. Due to a wide pKa range of humic-like substances, it is proposed that at pH 4, electrostatic interaction between humic substances and illite, with and without heavy metals, might have enabled the agglomeration of fine aluminosilicate particles. Some gold grains trapped in C–Si–Al agglomerates were released by the dissolution of humic-like substances in 1 M NaOH, resulting in a further increase in gold recovery of approximately 15%.

The sequential bio-treatment of refractory carbonaceous gold ore is a promising solution to recover gold effectively by environmentally friendly technology, which includes bio-oxidation of sulfide and biodegradation of carbonaceous matter by lignin-degrading enzymes. There are several drawbacks in enzyme treatment using cell-free spent medium (CFSM), including lignin peroxidase and manganese peroxidase from Phanerochaete chrysosporium, in particular the poor stability of enzyme activities. In the present work, laccase-mediator system (LMS) was applied for the degradation of carbonaceous matter in real gold ore to improve the efficiency of gold extraction as well as handling. The LMS was intended to be a great alternative process of CFSM with utilizing purified laccase in the presence of 1-hydroxybenzotriazole as a mediator. The application of LMS provided several advantages including not only greater stability, greater efficiency to degrade carbonaceous matter, better handling, much saving the treatment time, but also wider availability in laccase. In addition, replacing bio-oxidation with ferric chloride leaching as the dissolution path of sulfides facilitated avoiding the formation of jarosite and saving the required time. The gold recovery by cyanidation was improved from 41.5 ± 0.3% for the starting material to 81.3 ± 3.9% (n = 2) for the solid residues after the modified sequential pretreatment. This is correspondent to 86.3% of gold recovery for the extractable maximum gold excluding the enclosed gold in acid-insoluble silicates. The improved process involving LMS can be proposed with valuable advantages to fit a sustainable metallurgical technology of gold ores. [Display omitted] • Laccase-mediator system (LMS) was applied to real DRGO at the first time. • TG-DTA, Raman, and 3D fluorescence spectrometry supported the efficiency in LMS. • Gold recovery was improved to 86% after LMS treatment. • LMS could be established as an alternative of degradation of carbonaceous matters. • Ferric chloride leaching reduced sulfides without formation of jarosite.

GOLD ores , *LEACHING , *ETHYLENE , *GOLD compounds , *THIOUREA , *HYDROMETALLURGY - Abstract
[Display omitted] • Three gold ores with 2.70, 7.08 and 14.09 wt% Fe were leached with TU and ETU. • TU performed better than ETU for gold leaching from ore with the lowest Fe content. • ETU had a comparable gold extraction to cyanide for the most sulfidic gold ore. • Dissolved Au(TU) 2 + complex began decomposing after 12 hrs of leaching the sulfidic gold ores. • The addition of reductant improved Au extraction by TU from the most sulfidic gold ore. Environmentally friendly ligands, alternatives to cyanide, are desired to extract gold for the sustainable hydrometallurgy of gold. Leaching characteristics of gold were examined using thiourea (TU) and ethylene thiourea (ETU) as ligands from three types of gold ores with different Fe contents from 2.70 to 14.09 wt% under the acidic condition. The Au recovery by TU leaching reached the extractable maximum with the lowest Fe-bearing gold ore. This type of gold ore is suitable for TU/ETU leaching. The highest Fe-bearing gold ore was the most difficult to extract Au in ETU/TU leaching. There are at least two detrimental factors in TU leaching of Fe-rich gold ores, that is (i) the oxidative decomposition of TU, and (ii) complexation of TU with Fe3+, which both cause to deduce the complexation of TU with Au+. However, adding Na 2 SO 3 improved the Au extraction from such an ore to reduce Fe3+ to Fe2+. ETU facilitated the formation of more stable complexes with Au than TU against the coexisting Fe3+. This finding is useful when considering the cyanide-free leaching of different types of gold ores. [ABSTRACT FROM AUTHOR]

gold ores ,DRGO treatment ,gold recovery - Abstract
In carbonaceous gold ores, gold particles are mainly locked on sulfides, moreover, Au(CN)2- ions are easily adsorbed on coexisting carbonaceous matter during gold cyanidation causing the unignorable loss of gold recovery, therefore, such ores are called as double refractory gold ores (DRGO). In the previous study we reported that the sequential bio-treatments with bio-oxidation of sulfides followed by enzymatic biodegradation of carbonaceous matter much improved gold recovery. In the present work, DRGO with more highly graphitic carbon than previous study was challenged by beneficial changes of the sequential biotreatment including ferric leaching of sulfides, acid washing and degradation of carbonaceous matter by laccase. Gold recovery was totally improved from 42% to 81%, where acid washing avoided the agglomeration through Fe3+ adsorbed on different minerals and altered carbonaceous matter to facilitate the access of laccase. Compared with the performance of the conventional process using cell free spent medium derived from Phanerochaete chrysosporium instead of laccase,laccase treatment improved gold recovery and saved the required time. The present process can be proposed for DRGO treatment with valuable advantages from several aspects of time and energy as well as recovery of gold.

Science / Chemistry - Abstract
Double refractory gold ore (DRGO) not only include ppt levels of gold grains locked in sulfide minerals but also a problematic amount of carbonaceous matter. This causes a significant recovery loss of gold during cyanidation because of the strong affinity of the Au(CN)2‚àí with the carbonaceous matter. Combustion decreases the carbonaceous matter content, but also emits pollutant gases like CO2, SO2 and As2O3. Therefore, environmentally-friendly solutions have been explored by using biotechnology. Due to the very small amount of the above targets in the ore, it is challenging to show evidential changes in solid-phase before and after the biomineral processing of DRGO. This chapter introduces the mineralogical and chemical changes in the various solid residues produced during a sequential biotreatment, consisting of the liberation of gold from sulfides by an iron-oxidizer and decomposition of carbonaceous matter by lignin-degrading enzymes (lignin peroxidase, manganese peroxidase, laccase) secreted from a white rot-fungus, which successfully improved of gold recovery to over 90%. In addition, further development of biotechnology in the recovery of gold from DRGO is addressed.

- Abstract
We present a model of cold QCD matter that bridges nuclear and quark matter through the duality relation between quarks and baryons. The baryon number and energy densities are expressed as functionals of either the baryon momentum distribution, f_{B}, or the quark distribution, f_{Q}, which are subject to the constraints on fermions, 0≤f_{B,Q}≤1. The theory is ideal in the sense that the confinement of quarks into baryons is reflected in the duality relation between f_{Q} and f_{B}, while other possible interactions among quarks and baryons are all neglected. The variational problem with the duality constraints is formulated and we explicitly construct analytic solutions, finding two distinct regimes: a nuclear matter regime at low density and a quarkyonic regime at high density. In the quarkyonic regime, baryons underoccupy states at low momenta but form a momentum shell with f_{B}=1 on top of a quark Fermi sea. Such a theory describes a rapid transition from a soft nuclear equation of state to a stiff quarkyonic equation of state. At this transition, there is a rapid increase in the pressure.

- Abstract
Fully general-relativistic binary-neutron-star (BNS) merger simulations with quark-hadron crossover (QHC) equations of state (EOS) are studied for the first time. In contrast to EOS with purely hadronic matter or with a first-order quark-hadron phase transition (1PT), in the transition region QHC EOS show a peak in sound speed and thus a stiffening. We study the effects of such stiffening in the merger and postmerger gravitational (GW) signals. Through simulations in the binary-mass range 2.5

- Abstract
Previous studies have found the prevention paradox in the association between stroke events and a single specific risk factor, indicating that a population-based strategy may be more effective than a high-risk-based strategy for prevention. We tested the hypothesis that the prevention paradox does not apply when focusing on multiple potential risk factors simultaneously. The study cohort included 9051 individuals from Japan aged 40-89 years. The time-dependent Cox proportional-hazards models were used to identify the primary risk factor associated with stroke onset. We classified participants based on risk factors in two distinct ways: 1) classifying the high-risk group participants according to a single specific risk factor that had a large association with stroke in both sexes and all ages and 2) classifying the high-risk group participants according to 1-3 risk factor(s) including hypertension, hyperglycemia, and/or dyslipidemia. Then, we compared the proportions of the total number of participants who developed stroke in both groups to assess the prevention paradox. We found that hypertension was a primary risk factor for stroke incidence, regardless of sex and age. The percentage of patients with a single specific risk of and developed stroke was 46%-63%, while the percentage of patients with 1-3 risk factor(s) was 71-83%. This finding leads to the conclusion that the prevention paradox does not hold when multiple stroke risk factors were associated, suggesting that a high-risk-based strategy that focuses on patients with multiple risk factors may be more effective in preventing strokes., (Copyright © 2021 Elsevier Inc.

- Abstract
The mother's bond to her baby starts to develop during pregnancy, and it is related to the baby's attachment. We study how the mother's prenatal expectations of her unborn baby, the mother's adult relationships, and postnatal psycho-social factors (stress, depression, and anxiety) are related to the risk of bonding disturbance. The study comprised 1398 mothers and their unborn babies assessed both during pregnancy and when the babies were 3 months old (47.7% girls). The mother's risk of bonding disturbance was investigated using Brockington's Postpartum Bonding Questionnaire. According to the results, 71 (5.1%) of all the mothers in the study had a risk of a bonding disturbance. In a final adjusted logistic regression model, the most important risk factors were the mother's inability to form positive expectations about relationships with the baby during the third trimester of pregnancy (AOR = 7.78, p ≤ .001), maternal postnatal stress (AOR = 4.95, p ≤ .001) and maternal postnatal depression (AOR = 3.46, p ≤ .01). The results challenge healthcare professionals to screen pregnant mothers to identify at-risk groups for post-partum bonding disturbances. Intervention programs to prevent the development of bonding disturbances, and thus their possible serious consequences for children's development, should be considered., (© 2021 The Authors.

- Abstract
Safe obstetric care is a worldwide requirement. In Japan, a reduced number of obstetricians has prompted the centralization of obstetric facilities, and Japan's islands are expected to experience problems in handling deliveries. Although many pregnant women "move" to the mainland at later gestational weeks, "transport" from the island to the mainland may be occasionally needed when disorders manifest before the "move." Other women plan within-island deliveries; however, transport is required when complications arise. Managing delivery- or pregnancy-related problems may differ in transport by the population size of islands. We investigated the following issues in relation to the population size of Japan's islands: 1) How were deliveries handled on islands? 2) How many pregnant women were transported to the mainland? 3) What was the reason for and what affected transport? A total of 142 municipalities were selected to participate in a questionnaire survey, and 108 institutions from 106 municipalities responded. A comparative analysis by island size was performed using 2014 data: small-sized (population < 1,000), mid-sized (1,000 to 5,000), and large-sized (≥ 5,000). The percentage of women transported to the mainland from small-sized islands was significantly higher than that from large-sized islands (6.8 vs. 2.6% of all births in a year, respectively, P < 0.01). Transport was mainly in response to threatened preterm labor. Adverse weather was the most frequent factor affecting transport reliability. Our findings may contribute to a more detailed understanding of the state of obstetric care on Japan's islands.

- Abstract
Elucidating the perceptions of residents regarding medical group practice (GP) among rural communities (GP-R) in Japan will be useful for establishing this system in such communities. A survey by questionnaire, as made by experts in rural health, was conducted in 2017. The self-administered questionnaire inquired about the perceptions of residents for accepting the GP-R into the community's healthcare using seven major elements of GP-R. The questionnaire was randomly distributed to 400 adult residents who lived in rural communities with a recently launched GP and had access to clinics within the communities. Among the 321 respondents, comparisons were made between younger (≤sixties) and older (≥seventies) residents, and a stepwise multiple regression analysis was performed to extract the factors influencing acceptance of the GP-R system. The results showed that older residents had a greater disapprove of being treated by different physicians daily or weekly in clinics ( p < 0.001) and the use of telemedicine ( p < 0.001) compared with younger residents. Younger residents showed a greater disapproval of clinics closing on weekdays than older residents ( p = 0.007). Among all respondents, regardless of age groups, over half of residents approved of the involvement of nurse practitioners in the GP-R. Living with family and children was also extracted as an independent factor influencing a positive perception of the GP-R. These data suggest that the promotion of GP-R should consider generation gaps in the approach to medical practice as well as the family structures of residents. The involvement of nurse practitioners can also encourage the acceptance of GP-R in Japan.

- Abstract
Background: Globally, few published studies have tracked the temporal trend of dioxin levels in the human body since 2000. This study describes the annual trend of dioxin levels in human breast milk in Japanese mothers from 1998 through 2015., Methods: An observational study was conducted from 1998 through 2015. Participants were 1,194 healthy mothers following their first delivery who were recruited annually in Japan. Breast milk samples obtained from participants were analyzed using gas chromatography and mass spectrometry for dioxins, including polychlorinated dibenzo-p-dioxins (PCDDs), polychlorinated dibenzofurans (PCDFs), and coplanar polychlorinated biphenyls (PCBs)., Results: Mean age was 29.5 years, and 53% of participants were 20-25 years old. A declining trend in total dioxin levels was found, from a peak of 20.8 pg toxic equivalence (TEQ)/g fat in 1998 to 7.2 pg TEQ/g fat in 2014. Data from the last 5 years of the study indicated a plateau at minimal levels. In contrast, an increasing trend was found in the mean age of participants during the last 5 years. Although significantly higher dioxin levels were observed in samples from older participants, an upward trend in dioxin levels was not observed, indicating that dietary and environmental exposure to dioxins had greatly diminished in recent years., Conclusions: Dioxin levels in human breast milk may be approaching a minimum in recent years in Japan. The findings may contribute to global reference levels for environmental pollution of dioxins, which remains a problem for many developing countries.
