Japan’s environmental hazard control and consultation mechanism can give play to the role of public subjects and private subjects, realize the linkage and cooperation among citizens, enterprises and governments, and promote environmental control into a healthy and effective cycle. The illegal behavior of Japan’s nuclear-contaminated water discharge fully exposed the hypocrisy of its environmental control and consultation mechanism, indicating that the mechanism is still essentially a consultative democracy of a few people. In spite of this, Japan’s environmental hazard control and consultation mechanism before the 21st century can provide some reference for China’s environmental control mechanism in terms of the identification of the political identity of the residents, the maintenance of the enthusiasm of the enterprises and the diversified construction of the environmental education system.

Haloxyfop-R-methyl (HPME) is a selective herbicide for gramineous plants and has a removal effect on the coastal invasive organism Spartina alterniflora. In order to assess the risks of HPME on marine organisms in the governance process of Spartina alterniflora, this paper used the static-test method to evaluate the acute toxicity of HPME on four marine organisms. The results showed that four test organisms all showed muscle relaxation, decreased exercise capacity, and slow response under HPME exposure. As the test time prolonged, the mortality rate gradually increased, indicating that HPME had neurotoxicity and cumulative toxic effect on marine organisms. The 96 h median lethal concentration (LC50) of HPME for Mactra veneriformis、Apostichopus japonicus larvae、Cynoglossus semilaevis fry and Assiminea. lutea were were 0.888 mg/L, 1.382 mg/L、0.656 mg/L and 8.674 mg/L, respectively. The safe concentrations (SC) were 0.088 8 mg/L, 0.138 2 mg/L, 0.065 6 mg/L and 0.867 4 mg/L. According to the environmental safety assessment test guidelines for chemical pesticides, HPME was highly toxic to Cynoglossus semilaevis fry and Mactra veneriformis, and was moderately toxic to Apostichopus japonicus larvae and Assiminea. lutea. The results provided a reference for HPME in the elimination of Spartina alterniflora.

Studies on the spatial-temporal dynamic changes of fertilizer use and its eco-economic rationality in major grain production areas of China were made in order to provide some references for dealing with fertilizer’s non-point pollution, reduction of fertilizers and grain production safety. Based on the data of fertilizers consumption, crops sowing areas and grain yields during 1993-2017, fertilization eco-economic appropriate amount (FEAA) model and fertilization environmental safety coefficient (FESC) model were established to form the method to assess the rationalities of fertilizer use in major grain production areas of China. The results showed that the fertilization intensities in major grain areas of China increased from 205.5 kg/hm² in 1993 to 319.9 kg/hm² in 2017 and the fertilization intensities of nitrogen (N), phosphorus (P) and potassium (K) increased from 133.8, 48.0, 23.7 kg/hm² in 1993 to 162.6, 84.2, 73.2 kg/hm² in 2017, respectively. Proportion of N:P:K was from 1:0.4:0.17 in 1993 to 1:0.52:0.45 in 2017. FEAAs increased from 217.4 kg/hm² in 1993 to 300.6 kg/hm² in 2017. The fertilization intensities of N had been above the FEAA in 1993, P was above the FEAA from 2001, and K was close to its FEAA from 2009. So the higher risks of non-point pollution of N and P obviously existed. Shandong, Jiangsu and Henan Province were the highest fertilization intensity center during 1993-2017, with other sub-intensity provinces around. In 2017, Henan Provine had the highest fertilization intensity with 462 kg/hm², while Helongjiang Province had the lowest fertilization intensity with 170 kg/hm². Among the 13 provinces of grain production areas, 7 areas, Henan, Jiangsu, Shandong, Hubei, Hebei, Anhui and Inner Mongolia, were all individually beyond their own FEAAs with their fertilization efficiencies lower than the average in 2017, while the other 6 areas were close to or less than their FEAAs with their fertilization efficiencies higher than the average, especially Jilin and Hunan Province was with win-win development of grain production and environmental safety. In 2017, Henan belonged to eco-economic irrationality area due to overuse of fertilizers; Hebei, Jiangsu, Anhui, Shandong and Hubei Province belonged to economic rational and ecological irrational areas of fertilization; Hunan, Jilin, Liaoning and Inner Mongolia belonged to eco-economic rational areas of fertilization. Heilongjiang, Sichuan and Jiangxi Province were ecological rational and economic irrational fertilization areas because of insufficient fertilizer use. So there were great differences of fertilization intensities and rationalities in major grain production areas of China. Overall, the fertilizers were overused in China, but some areas were underused. Governments at all levels should classify the major grain production areas into different sorts of fertilization, and determine the categories of overused, rational used or insufficient used in fertilization. Guidance should be given to farmers to upgrade the grain yield and prevent fertilizer’s non-point pollution, and organic fertilizers should be encouraged to use, and the construction of fertilization standards and information services should be reinforced.

The degradation property of pesticide is an important index for environmental safety assessment. In order to assess the water environmental safety of the botanical pesticide matrine, both the hydrolysis dynamics in sterilized buffer water and degradation properties in natural water were studied according to China national stands Chemical Pesticide Environmental Safety Evaluation Test Guidelines. The results showed that hydrate rate of matrine in buffered water was less than 25% after 120 d. However, it was very faster in natural water system with the half-life ranged from 6.26 d to 2.87 d, and the sequence of hydrolytic speed in different systems was: pool water > river water > rain > lake > sea > tap-water. The degradation speed displayed a negative correlation with the initial concentration of matrine in 6 kinds of natural water systems (25 ℃ ± 1 ℃), while the half-life would be prolonged as the initial concentration increased. Given that the half-life was less than 1 month, the degradation is relatively easy. The comparative studies indicated that the hydrolytic speed of matrine was mainly influenced by microorganisms in the water, and the half-life was significantly and negatively correlated with the quality of microorganisms (P = 0.006). Above all, matrine would be easily degraded in natural water systems and was safe to water environment. [ABSTRACT FROM AUTHOR]

In this paper, the genetically modified rice HUAHUI-1 was used as test material which was planted around by some non-transgenic rice cultivars, their F1 seeds from the HUAHUI-1 were collected at different distance, and their hybrid seedlings with foreign Bt gene were identified by PCR technique. The frequency of gene flow from insect-resistance transgenic rice to conventional rice varieties at each sampling site was count and analyzed. The results showed that the frequency of Bt gene flow to P13381 and Chunjiang063 were zero. And the foreign Bt gene would flowed more or less to the HEXI22-2, TIANXIANG, MINGHUI63 and P1157, the mean value of frequency was no more than 0. 88 % and dropped gradually with the distance increasing until it were zero at sampling point 7 m far away. Those useful measures, such as rational field arrangement, suitable distance for physical segregation, scientific farming planning to avoid flowering at the same time, could control effectively and prevent the foreign gene of transgenic rice flowing away, and then lower the ecological risks from foreign gene escaping. The results indicated that PCR method could detect the hybrid strains accurately, but it would take a long time and had a heavy workload. More simple and efficient methods would be explored to evaluate the flow frequency of those transgenic plants without marker gene. [ABSTRACT FROM AUTHOR]

Transgenic technology has developed rapidly in recent years. The environmental risk of the release of transgenic organisms is still a key issue. Research on the impacts on biodiversity is an effective way to objectively evaluate the risk. By taking transgenic maize HGK60 with insect-resis-tant gene Cry1Ah and common maize Zheng58 as control, we examined the diversity of arthropods and weeds in spring and winter of 2018 in Hainan Province. 43753 arthropods belonging to 69 species, 19 families, and 7 orders were obtained. There was no significant difference in arthropod community composition, structure and ecological indices between HGK60 and Zheng58. Compared with Zheng58, the transgenic insect-resistant maize HGK60 had obvious resistance to wood boring beetles. 16 species of weeds belonging to 8 families were recorded in the field. There was no significant difference in the density and ecological indices of weeds between HGK60 and Zheng58, with almost the same change trends in the whole growth period. Our results suggested that planting transgenic maize HGK60 with insect-resistant gene Cry1Ah did not affect biodiversity of arthropods and weeds. The results provided scientific support for the further studies of environmental risk of transgenic crops.
