As iniciativas de governança comunitária no manejo florestal ainda estão longe de se tornarem efetivamente arranjos institucionais descentralizados do poder público, ainda há uma forte dependência do Estado no apoio à organização, planejamento e meios de uso dos recursos naturais. Essa dependência também é evidenciada em parceria com organizações não governamentais, o que tem demonstrado pouca efetividade nas ações e no empoderamento comunitário a longo prazo. Na Amazônia Paraense são poucos os exemplos de casos que resultaram no protagonismo de povos e comunidades tradicionais, no tocante ao uso comum dos recursos florestais. Esta pesquisa tem por objetivo descrever a experiência de cinco comunidades ribeirinhas da Reserva Extrativista Verde para Sempre, localizada no município de Porto de Moz, no Oeste do Estado do Pará, onde tiveram a iniciativa de implementar um modelo de gestão dos recursos de base comunitária, com exploração florestal na lógica de um manejo adaptativo, de acordo com suas condições e necessidades. Aqui é apresentado como foi construído de forma participativa esse modelo denominado de “governança local”, que possibilitou o processo de condução direta da gestão pelas comunidades, onde as mesmas articularam com os atores envolvidos por meio de uma parceria formal, sem descaracterizar os interesses dos usuários. Os resultados revelaram que as comunidades estudadas têm avançado satisfatoriamente no alcance de suas metas, sendo consideradas iniciativas promissoras que podem ser multiplicadas. Constatou-se que a partir desse caso considerado emblemático, o órgão gestor da RESEX tem adotado uma postura de cogestão colaborativa, ao ponto de poder reconhecer esse modelo de governança e possibilitar a resignificação do manejo florestal comunitário, hoje considerado tecnicista. O artigo compartilha percepções socioambientais e lições aprendidas de cinco anos de observação empírica (2010-2015), a fim de contribuir para esse debate que ainda em seu início.

Introdução: A degeneração progressiva dos neurónios do Locus Coeruleus associada à diminuição de recetores adrenérgicos, alvos da Noradrenalina, conduz a uma diminuição da função cerebral, provocando uma baixa resposta hemodinâmica e atividade neuronal. A disfunção noradrenérgica pode, ainda, interromper a capacidade de monitorizar estímulos externos e alterar o processo cognitivo da atenção, como acontece na Doença de Alzheimer e na Doença de Parkinson. Objetivos: A investigação procurou unir estudos estruturais e funcionais do Locus Coeruleus, incluindo estudos pupilométricos na avaliação da atenção seletiva visual, que atendessem à resposta cerebral bem como à progressão da doença, com a finalidade de correlacionar o processo cognitivo de atenção com a imagem obtida por Ressonância Magnética do Locus Coeruleus. Materiais e Métodos: A estratégia de pesquisa foi desenvolvida para encontrar todos os potenciais artigos relevantes num conjunto de fontes, como: as bases de dados bibliográficas de biomedicina; bases de registos de ensaios clínicos randomizados e quase randomizados; repositórios científicos e sites agregadores de bases bibliográficas. Resultados: Estudos que avaliaram o Locus Coeruleus por Ressonância Magnética demonstram variações morfológicas dependentes da idade e estudos funcionais, juntamente com testes pupilométricos, apresentaram alterações na neuromodulação percutindo-se na seletividade da atenção. Conclusão: A compilação da análise dos estudos forneceu dados para o estudo do Locus Coeruleus e a relação com o processo cognitivo de atenção. Cientificamente, todos os aspetos morfológicos e funcionais sugerem possibilitar a análise da disfunção noradrenérgica sob o campo da imagem de Ressonância Magnética para compreender a incapacidade do Locus Coeruleus em monitorizar estímulos externos e alterar o processo cognitivo da atenção.

Climate change’s huge impact on Mediterranean species’ habitat suitability and spatial and temporal distribution in the coming decades is expected. The present work aimed to reconstruct rockrose (Cistus ladanifer L.) historical and future spatial distribution, a typically Mediterranean species with abundant occurrence in North Africa, Iberian Peninsula, and Southern France. The R ensemble modeling approach was made using the biomod2 package to assess changes in the spatial distribution of the species in the Last Interglacial (LIG), the Last Glacial Maximum (LGM), and the Middle Holocene (MH), in the present, and in the future (for the years 2050 and 2070), considering two Representative Concentration Pathways (RCP 4.5 and RCP 8.5). The current species potential distribution was modeled using 2,833 occurrences, six bioclimatic variables, and four algorithms, Generalized Linear Model (GLM), MaxEnt, Multivariate Adaptive Regression Splines (MARS), and Artificial Neural Networks (ANN). Two global climate models (GCMs), CCSM4 and MRI-CGCM3, were used to forecast past and future suitability. The potential area of occurrence of the species is equal to 15.8 and 14.1% of the study area for current and LIG conditions, while it decreased to 3.8% in the LGM. The species’ presence diaminished more than half in the RCP 4.5 (to 6.8% in 2050 and 7% in 2070), and a too low figure (2.2%) in the worst-case scenario (RCP 8.5) for 2070. The results suggested that the current climatic conditions are the most suitable for the species’ occurrence and that future changes in environmental conditions may lead to the loss of suitable habitats, especially in the worst-case scenario. The information unfolded by this study will help to understand future predictable desertification in the Mediterranean region and to help policymakers to implement possible measures for biodiversity maintenance and desertification avoidance.

Objectives The aim of this article is to provide a comprehensive literature review, gathering the strongest evidence about the risks and benefits and the prescription of physical exercise during pregnancy. Content Regular physical exercise during pregnancy is associated with numerous benefits. In general women are not adequately advised on this matter. Along with their concerns regarding the potential associated risks, it contributes to the abandonment or refusal to start exercising during pregnancy. A systematic review was conducted in MEDLINE including articles considered to have the highest level of scientific evidence. Fifty-seven articles, including 32 meta-analysis, 9 systematic reviews and 16 randomized controlled trials were included in the final literature review. Summary Exercise can help preventing relevant pregnancy related disorders, such as gestational diabetes, excessive gestational weight gain, hypertensive disorders, urinary incontinence, fetal macrosomia, lumbopelvic pain, anxiety and prenatal depression. Exercise is not related with an increased risk of maternal or perinatal adverse outcomes. Compliance with current guidelines is sufficient to achieve the main benefits, and exercise type and intensity should be based on woman’s previous fitness level. Outlook Exercise in pregnancy is safe for both mother and fetus, contributing to prevent pregnancy related disorders. Exercise type and intensity should be adapted to woman’s previous fitness level, medical history and characteristics of the ongoing pregnancy.

Introduction: The area’s studies have a great relevance in artwork. Laboratories committed to this purpose are scarce and employ professionals without specific knowledge in handling of ionizing radiation. It is not known to what extent, in Portugal, clinical radiological centers could provide added value to technology of digital radiography applied to painting, in order to expand their business areas and the performance of radiographers, thus enhancing synergies between these two areas. Goals: It was intended to analyse a possible applicability, to painting, of the Digital Radiology systems (CR and DR), used in the clinic settings, through the evaluation of the variable “radiographic image quality”, since the systems Clinical radiological tests, with indirect or direct conversion detectors of different energies and photodetectors of the electrical signal, show significant improvements in imaging patterns. Material and Methods: 21 radiographs were obtained from exposures made over three paintings in three different radiological systems with an emphasis on exposure parameters (potential difference (kV) and current intensity (mAs)). The sample was directed to works that presented different techniques, materials and compositions and selected by a museologist. The quality of the radiographs, operationalized by the analysis’s dimensions used in the evaluation of artworks: preservation of the support; distinction of details; contrast; contour definition; creative and technical process and components / materials. Four observers (2 specialists in medical image and 2 in art), under conditions of independence, evaluated the radiographs acquired according to a 4-point Likert scale. The analysis dimensions were organized into 11 criteria and the conditions for structured observation of the radiographs were standardized for display on a 15.6 ”GeChic 1503H monitor. Results: The most graded images were obtained with the Computerized Radiography (CR) system (mode: 3) given that this technology, in the opinion of the observers, provided a better view of the analysis criteria previously defined. The results were presented using descriptive statistics and discrete categorical variables, grouped into modal classes. Conclusions: Clinical digital radiography, especially Computed Radiography (CR), applied to painting, showed considerable dimensions of image quality and its use can contribute to the conservation, restoration, validation, analytical study, dating and authentication of artworks.

A mamografia digital é, atualmente, o pilar do programa de rastreio do cancro da mama, contudo a densidade mamária afeta negativamente a sua performance de diagnóstico, diminuindo a sua sensibilidade devido ao efeito – designado em Radiologia “efeito máscara”. Com o objetivo de superar este inconveniente, a tomossíntese tem conseguido bons resultados em mulheres com elevada densidade mamária, devido à sua capacidade de reduzir as falsas imagens resultantes da sobreposição dos tecidos. Este estudo pretende explorar a literatura no que diz respeito à integração da tomossíntese nos programas de rastreio para avaliação de mulheres com elevada densidade mamária, com base nos indicadores clínicos: taxa de rechamada – recall rate, fração de falsos positivos (FFP) e taxa de deteção de lesões. Da pesquisa na literatura resultaram 79 estudos, dos quais 11 foram incluídos para análise. Verifica-se que a utilização da tomossíntese mais mamografia está associada à redução da recall rate, em todas as categorias ACR, mas maioritariamente na categoria C (Starikov A. et al, 2016) atingindo 8,83% para a tomossíntese e 10,98% para a mamografia (Alsheik N. et al, 2019), e 10,4% para a tomossíntese e 19,9% para a mamografia no estudo de Conant E. et al, 2019. A FFP também beneficia duma diminuição, porém, aumenta com o aumento das categorias ACR sendo cerca de 5 vezes superior na categoria D. A taxa de deteção de lesões também aumentou com a adoção da tomossíntese sendo cerca de 1,41 vezes superior em cada 1000 mulheres, e com maior expressão em mulheres com tecido mamário denso. Conclui-se que o uso isolado da tomossíntese ou a sua adição à mamografia demonstra resultados muito positivos, dado que esta modalidade de imagem contribui para a deteção de lesões de menores dimensões e, consequentemente, aumento da taxa de deteção de lesões, aumento da especificidade, diminuição da recall rate e FFP. Por este motivo a tomossíntese demonstra ser uma técnica promissora e pode representar uma resposta eficaz nos programas de rastreio.

Fruit production, as an elementary chemical characteristic of the fruit, was evaluated in 16 Opuntia ficus-indica Portuguese ecotypes cultivated in a marginal soil without tillage, in the second and third years after plantation. The O. ficus-indica ecotypes were compared with the Italian cultivars ‘Bianca’ and ‘Gialla’. Significant differences were found among the O. ficus-indica ecotypes in biomass-related parameters and fruit yield, and different groups were established. Two spineless ecotypes (OFI-12 and OFI-13) had highest biomass production, with 9.9 Mg/ha dry matter on average. This was not significantly different from the ‘Gialla’ cultivar, which averaged 11.9 Mg/ha, for a density of 2,667 plants/ha, in the third year after plantation. Among Portuguese ecotypes, the fruit yields ranged from 2.4 to 10.1 Mg/ha fresh weight. The cultivars ‘Gialla’ and ‘Bianca’ had the highest fruit yield (13.8 and 13.6 Mg/ha fresh weight, respectively). The ‘Gialla’ cultivar and the group of ecotypes with orange pulp produced fruits of larger size and weight compared to the ‘Bianca’ cultivar and the group of ecotypes with white pulp info:eu-repo/semantics/publishedVersion

Climate change is already a reality, and habitat loss is affecting relentlessly tree species distributions. The strawberry tree (Arbutus unedo L., Ericaceae) is a Mediterranean evergreen tree used in this article as a case study to evince its expected threatening situation in the upcoming age. This research work seeks to identify the bioclimatic and physiographic variables that have the most impact on the strawberry tree’s spatial distribution in Portugal, acquiring vital knowledge for the design of accurate conservation and afforestation plans for the use and conservation of strawberry tree, working as a guide under a climate change scenario. For that, twenty-one bioclimatic variables, two physiographic attributes (altitude and slope), and the Emberger Index (EI) were used together with 318 observations of strawberry trees, to build a scalable Bayesian procedure, based on machine learning techniques, aimed to assess the species’ future habitat evolution through three temporal scenarios: (i) Control Run (1960–1990); (ii) 2050 and (iii) 2070. The results indicate for 2050 a 30% loss of the humid sub-region and a 35% increase in the semi-arid sub-region towards the north. In 2070, it is expected a 2% recuperation for the sub-humid area, but an 8% loss of the humid sub-area. Under these extreme climate change conditions, it is anticipated an almost complete loss of habitat for the strawberry tree in the south of Portugal. The expected ecological evolvability may trigger future migration paths and new refuges’ settlement in the northern sub-region for the succeeding decades and suggesting after 2070 the possibility of habitat switch and species drifting.

SUMMARYIn marginal lands Opuntia ficus-indica (OFI) could be used as an alternative fruit and forage crop. The plant vigour and the biomass production were evaluated in Portuguese germplasm (15 individuals from 16 ecotypes) by non-destructive methods, 2 years following planting in a marginal soil and dryland conditions. Two Italian cultivars (Gialla and Bianca) were included in the study for comparison purposes. The biomass production and the plant vigour were estimated by measuring the cladodes number and area, and the fresh (FW) and dry weight (DW) per plant. We selected linear models by using the biometric data from 60 cladodes to predict the cladode area, the FW and the DW per plant. Among ecotypes, significant differences were found in the studied biomass-related parameters and several homogeneous groups were established. Four Portuguese ecotypes had higher biomass production than the others, 3.20 Mg ha−1 on average, a value not significantly different to the improved ‘Gialla’ cultivar, which averaged 3.87 Mg ha−1. Those ecotypes could be used to start a breeding program and to deploy material for animal feeding and fruit production.

Species ecological envelope maps were obtained for the two main Portuguese wood-production species (Eucalyptus globulus Labill. and Pinus pinaster Aiton) and projected future climate change scenarios. A machine learning approach was used to understand the most influential environmental variables that may explain current species distribution and productivity. Background and Objectives: The aims of the study were: (1) to map species potential suitability areas using ecological envelopes in the present and to project them in the future under climate change scenarios, (2) to map species current distributions, (3) to map species current productivity, and (4) to explore the most influential environmental variables on species current distribution and productivity. Materials and Methods: Climate, elevation data, and soil data sets were used to obtain present and future species ecological envelopes under two climate change scenarios. The official land cover maps were used to map species distributions. Forest inventory data were used to map the species productivity by geostatistical techniques. A Bayesian machine learning approach, supported by species distributions and productivity data, was used to explore the most influential environmental variables on species distribution and productivity and to validate species ecological envelopes. Results: The species ecological envelope methodology was found to be robust. Species&rsquo, ecological envelopes showed a high potential for both species&rsquo, afforestation. In the future, a decrease in the country&rsquo, s area potentiality was forecasted for both species. The distribution of maritime pine was found to be mainly determined by precipitation-related variables, but the elevation and temperature-related variables were very important to differentiate species productivity. For eucalypts, species distribution was mainly explained by temperature-related variables, as well as the species productivity. Conclusions: These findings are key to support recommendations for future afforestation and will bring value to policy-makers and environmental authorities in policy formulation under climate change scenarios.

Olea europaea ssp. europaea (Oleaceae) grows in Mediterranean countries. The Galega represents one of the most common Portuguese olive tree cultivars, and is used in five out of the six PDO (Protected Designation of Origin) regions. The fruits are used for olive oil and for fruit canning, besides which the cultivar is drought tolerant. The cultivar certification is done through phenotypic characteristics, but environmental influence might blur informativeness, and molecular markers could help in clarifying cultivar accessions certification. A total of 75 putative Galega accessions considered as belonging to the Galega cultivar, three previously phenotypically identified as GGN (Galega Grada Normal), GGS (Galega Grada de Serpa) and GGE (Galega Grada de Evora), and one as a non-Galega blind control were analyzed. Twenty RAPD primers amplified 144 bands and 32% were polymorphic. A low expected heterozygosity was estimated (10%), as expected for clonal propagated plants. The Principal Component Analysis (PCA) clearly identified two groups. Group A was comprised of all the putative Galega accessions including GGN, but not individual #502. Group B included NG, GGE, GGS and #502. The analysis of molecular variance confirmed a very high differentiation between the two groups (88%), but also some within groups’ diversity (12%). Group A individuals cluster closely to GGN. Assuming that the GGN individual represents a Galega cultivar tree, we might assume that all the A group trees are Galega cultivar accessions. Nevertheless, some within group variability exists, may be due to the accumulation of somatic mutations and/or a putative origin from different, but related genotypes. Finally, the GGS, the GGE, and the #502 plot together with the individual identified as non Galega cultivar tree. Group B trees certainly had a very different genetic origin compared to the group A genotypes, which confirms some differences found in the morphologic characteristics compared to the ordinary Galega cultivar, reflected in the name differences. The pairwise matrix computed with the Dice similarity index was also used to obtain a dendrogram. Results were similar, but slightly different from the PCA. Three clusters were obtained. This indicates that the B group could be split into two sub-groups. A future study using a broader sampling and higher discriminant molecular markers, such as microsatellites, would help to reveal the phylogeny among the 3 cultivars (GGN, GGS and GGE) and to clarify if the intra-variability of those cultivars is geographically related.

The strawberry tree (Arbutus unedo L.) is an underutilized, drought tolerant, fire resistant species with a south western distribution in Europe, and with ecological and putative socio-economical impact in Portugal and Mediterranean countries. Our aim was to develop an appropriate set of molecular markers to enable genetic diversity to be assessed and to fingerprint Arbutus unedo genotypes for breeding and conservation purposes in Portugal. Twenty-seven trees from a broad geographic range were screened with 20 random amplified polymorphic DNA (RAPD primers) and 11 microsatellite markers (SSR). The RAPDs generated 124 bands, 57.3% of which were polymorphic, with an expected heterozygosity of 27%. We cross-amplified 11 SSR primers developed for Vaccinium spp., and 5 were found to be polymorphic in A. unedo, with 75% of expected heterozygosity, a number of alleles of 11.6, a null allele frequency of 7.6% and a polymorphic information content of 71%. Although the SSRs were more polymorphic and informative than the RAPDs, both markers displayed high genetic variability with the gathered data. No geographic pattern was observed in the genetic variation distribution based on both marker systems, and the lack of correlation between genetic and geographical matrices was confirmed by Mantel tests. Likely, no correlation was found between pairwise SSR and RAPD band-sharing matrices. These results and their implications on A. unedo breeding and conservation programs are discussed.

To assess the genetic patterns of colonisation of metalliferous areas by the pseudometallophyte Cistus ladanifer with AFLP genome scan, to compare those estimates with previous cpSSR results, and to identify loci potentially linked to tolerance to metalliferous soils. Thirty-three populations were screened with AFLP markers. Statistical analyses included estimation of genetic diversity, hierarchical analysis of molecular variation and Bayesian analysis of geographical partitioning of genetic diversity. Mantel tests and Spearman’s correlation index were used to compare results obtained with AFLP and cpSSR. Generalized Estimating Equations (GEE) models were applied to correlate allele frequency distribution and soil variables (pH, Ca:Mg ratio and total contents of different trace metals). Metallicolous and non-metallicolous populations of C. ladanifer showed neither different levels of genetic diversity, nor genetic differentiation between population types. Incongruence in genetic diversity estimates between AFLP and cpSSR due to marker-specific properties was observed. Nonetheless, pairwise distance matrices computed with both markers were concordant. GEE analyses showed that the Mn total soil content has an important effect on the allele distribution in C. ladanifer. In contrast, the Ca:Mg ratio seems to have no selective effect. Moreover, we identified a particular band with a putative role in the species’ tolerance to high Mn concentrations in the soil. The soil type had no influence over this species’ genetic structure. GEE showed their usefulness in revealing the association between soil variables and AFLP loci.

The Opuntia spp., most likely few individuals, were introduced in the Iberian Peninsula in the beginning of the 16th century, after the discovery of America, spreading afterwards throughout the Mediterranean basin. We analysed, for the first time, the genetic diversity in a set of 19 Portuguese Opuntia spp. populations from the species O. ficus-indica, O. elata, O. dillenii and O. robusta using nuclear microsatellite (nuSSR) markers. The Italian cultivars ‘Bianca’, ‘Gialla’ and ‘Rossa’ were included in the study for comparison purposes. The nuSSR amplifications produced from five to 16 alleles, with an average of 9.2 alleles per primer pair, and average polymorphism information content of 0.71. The estimated Dice coefficient among populations varied from 0.26 to 1.0, indicating high interspecific genetic diversity but low genetic diversity at the intraspecific level. The hierarchical clustering analysis revealed four major groups that clearly separated the four Opuntia species. Among the O. ficus-indica populations, two sub-clusters were found, one including the white pulp fruits (with cv. Bianca) and the other with the orange pulp ones and including the cv. Gialla, the cv. Rossa, and one pale yellow pulp population. No genetic differences were found between the inermis form, O. ficus-indica f. ficus-indica, and the rewilded spiny one, O. ficus-indica f. amyclaea. The dendrogram indicated that the clustering pattern was unrelated to geographical origin. The results revealed a low level of genetic diversity among the Portuguese populations of O. ficus-indica. info:eu-repo/semantics/publishedVersion

We compared the genetic variation of Pinus pinaster populations using amplified fragment length polymorphism (AFLP) and chloroplast simple-sequence repeat (cpSSR) loci. Populations' levels of diversity within groups were found to be similar with AFLPs, but not with cpSSRs. The high interlocus variance associated with the AFLP loci could account for the lack of differences in the former. Although AFLPs revealed much lower genetic diversity than cpSSRs, the levels of among-population differentiation found with the two types of marker were similar, provided that loci showing fewer than four null-homozygotes, in any population, were pruned from the AFLP data. Moreover, the French and Portuguese populations were clearly differentiated from each other, with both markers. The Mantel test showed that the genetic distance matrix calculated using the AFLP data was correlated with the matrix derived from the cpSSRs. Because of the concordance found between markers we conclude that gene flow was indeed the predominant force shaping nuclear and chloroplastic genetic variation of the populations within regions, at the geographical scale studied.

International audience; Maritime pine seed-lots from north-western Iberian regions (Portugal and Galicia) were introduced in the 1950s to the south-west of France (Aquitaine region), and the stands they formed suffered considerable frost damage. In the mid 1980s, a biochemical test was developed to test the putative origin of adult stands in Aquitaine, before seeds could be distributed for commercial purposes in France. In this paper, we describe a new test employing chloroplast simple-sequence repeats (cpSSRs) to facilitate identification of stand origin based on randomisation tests. The origin of five stands of unknown origin was determined with both the cpSSR and biochemical (terpene profile analysis) tests. The results from the two tests were concordant, but the DNA-based test gave faster and more accurate results. Use of this test should help when determining the origin of maritime pine stands in the Aquitaine region of France.; Des lots de graines du nord ouest de la péninsule ibérique (Portugal et Galice) ont été introduits dans les années 1950 dans le sud-ouest de la France (Aquitaine), et les peuplements issus de ces graines ont fortement souffert des gelées. Un test variétal basé sur les marqueurs terpéniques fut développé dans les années 1980 afin d'identifier l'origine géographique des peuplements adultes en Aquitaine sur lesquels des graines étaient récoltées puis commercialisées. Dans cet article nous décrivons un nouveau test qui utilise des marqueurs microsatellites chloroplastiques (cpSSRs) et simulations pour identifier l'origine des peuplements. Une étude comparative des tests biochimique (terpènes) et cpSSR a été menée sur cinq peuplements adultes. Les résultats obtenus sont identiques, mais le test ADN s'est avéré plus rapide et plus précis. L'utilisation de ce nouveau test devrait permettre de garantir l'origine géographique des peuplements de pin maritime du sud-ouest de la France (Aquitaine).

As alterações significativas ocorridas no trabalho resultaram em riscos emergentes. Entre eles, os riscos psicossociais têm sido objeto de um, recente e crescente, interesse em virtude do seu aumento e do incremento da sua visibilidade. Os riscos psicossociais são riscos para a saúde mental, física e social, originados pelas condições de trabalho e pelos fatores organizacionais e relacionais suscetíveis de interagir com o funcionamento mental. Os fatores psicossociais de risco no trabalho podem ser agrupados em seis dimensões: intensidade do trabalho e tempo de trabalho; exigências emocionais; falta/insuficiência de autonomia; má qualidade das relações sociais no trabalho; conflitos de valores e insegurança na situação de trabalho. Neste sentido, o objeto de análise visa identificar e conhecer os riscos psicossociais presentes no ambiente laboral dos trabalhadores da recolha de resíduos sólidos urbanos, bem como os fatores que estão na sua origem. A reflexão da medição dos fatores psicossociais de risco foi realizada através da aplicação de um questionário - PsicoQuest, que foi elaborado com base na abordagem de Gollac & Bodier (2011). Assim, pela aplicação do PsicoQuest e análise dos respetivos dados verificou-se que, os trabalhadores da recolha de resíduos estão sujeitos a um maior risco quando expostos a situações relacionadas com os conflitos de valores, autonomia, intensidade e tempo de trabalho. Nomeadamente, pela inexistência de recursos humanos suficientes e de recursos materiais suficientes e adequados, pelo receio de não terem rendimentos suficientes, pela falta de oportunidade de progredirem na carreira e pela falta de reconhecimento do trabalho. Contudo, estes trabalhadores sentem-se satisfeitos com o seu trabalho. Foi possível ainda observar que, os problemas de saúde mais frequentes, identificados pelos trabalhadores, foram as dores nas costas e as dores musculares. Identificou-se ainda a necessidade de se realizarem mais estudos, de forma a detetar e identificar atempadamente os fatores que estão na origem dos riscos psicossociais e qual a melhor forma de intervir na sua prevenção, com vista a melhorar a saúde, segurança e bem-estar de todos os trabalhadores.
