[hal-04067839] Long-Term Maintenance Strategies after Pulmonary Rehabilitation: Perspectives of People with Chronic Respiratory Diseases, Informal Carers, and Healthcare Professionals
Pulmonary rehabilitation (PR) is an effective intervention for people with chronic respiratory diseases (CRD); however, its effects fade after 6-12 months. Community-based strategies might be valuable to sustain PR benefits, but this has been little explored. People with CRD, informal carers, and healthcare professionals (HCPs) were recruited from pulmonology appointments of two local hospitals, two primary care centres, and one community institutional practice and through snowballing technique. Focus groups were conducted using a semi-structured guide. Data were thematically analysed. Twenty-nine people with CRD (24% female, median 69 years), 5 informal carers (100% female, median 69 years), and 16 HCPs (75% female, median 36 years) were included. Three themes were identified: "Maintaining an independent and active lifestyle" which revealed common strategies adopted by people with "intrinsic motivation and professional and peer support" as key elements to maintain benefits, and that "access to information and partnerships with city councils' physical activities" were[…]

[hal-04067760] Using a Portuguese regosol to derive soil reference values for arsenic
Soil reference values (SRV) are preliminary screening benchmark values used to evaluate the potential toxicity of specific contaminants in soils. The Portuguese Environmental Agency has proposed SRV for metals and metalloids based on soil uses but without consideration for the soil type. This project aims to derive SRV for arsenic (As) using a natural Portuguese soil since it is known that soil properties can influence the mobility and bioavailability of contaminants. To achieve this aim, a non-contaminated regosol was collected and spiked with a range of concentrations of As. After, a battery of ecotoxicological tests was performed using the spiked soil, including microbial parameters, reproduction with invertebrates, plant growth assays, and aquatic organisms (to evaluate elutriates from the spiked soil) following standard protocols (ISO and OECD) and aimed at deriving concentrations that cause a x% effect (ECx) to the tested organism and/or the test endpoints assessed. The endpoints will be[…]

[hal-04060807] Short-Term Responses of Soil Microbial Communities to Changes in Air Temperature, Soil Moisture and UV Radiation
We analyzed the effects on a soil microbial community of short-term alterations in air temperature, soil moisture and ultraviolet radiation and assessed the role of invertebrates (species Enchytraeus crypticus) in modulating the community’s response to these factors. The reference soil, Lufa 2.2, was incubated for 48 h, with and without invertebrates, under the following conditions: standard (20 °C + 50% water holding capacity (WHC)); increased air temperature (15–25 °C or 20–30 °C + 50% WHC); flood (20 °C + 75% WHC); drought (20 °C + 25% WHC); and ultraviolet radiation (UV) (20 °C + 50% WHC + UV). BIOLOG EcoPlates and 16S rDNA sequencing (Illumina) were used to assess the microbial community’s physiological profile and the bacterial community’s structure, respectively. The bacterial abundance (estimated by 16S rDNA qPCR) did not change. Most of the conditions led to an increase in microbial activity and a decrease in diversity. The structure of[…]

[hal-02926382] Deposição atmosférica de poeiras e níveis de elementos traço numa cidade industrial no litoral centro de Portugal
O presente estudo pretendeu (i) identificar padrões geoquímicos espaciais e temporais na deposição atmosférica, e (ii) avaliar potenciais contribuições de fontes locais e alóctones para a composição química das poeiras atmosféricas no concelho de Estarreja. Dois coletores foram colocados em áreas exteriores de duas escolas localizadas poucos quilómetros a sul da zona industrial. A recolha das amostras foi realizada mensalmente, de maio a agosto de 2018. As frações solúvel e insolúvel da deposição atmosférica foram analisadas por ICP-MS para determinar as concentrações quase-totais dos elementos químicos. Os resultados mostram a ocorrência de dois eventos distintos de maior fluxo de deposição atmosférica: (i) um em maio, caracterizado pela deposição de elementos traço em formas solúveis, detetado em ambas as escolas e (ii) um segundo em agosto, caracterizado pela deposição de elementos maiores em formas insolúveis, detetado apenas na escola mais distante do complexo industrial. No geral, os resultados indicam uma deposição[…]

[halshs-01857735] Entre terre et eau contaminées: populations, institutions et perceptions du risque
Cet article a pour objectif de contribuer à la réflexion sur la protection et la sauvegarde des environnements sensibles, ici en partie pollués, et de répondre à l'une des propositions très précises de l'argumentaire du panel II, à savoir : « après avoir identifié les problèmes, que la prochaine étape soit la mise en oeuvre de mesures concrètes, sur base scientifique, pour enrayer la détérioration et restaurer les écosystèmes aquatiques ». Il s'agit aussi de répondre à la requête de certains de nos interlocuteurs sur le terrain, soucieux de « continuer à parler d'Estarreja, pour qu'on ne nous oublie pas, et pour que des mesures pour la protection des populations et de l'environnement continuent d'être prises ». En tant qu'anthropologue, il m'est difficile d'agir directement sur la mise en oeuvre de mesures concrètes pour la protection des écosystèmes. En revanche, je peux contribuer par une approche socio-anthropologique à restituer une[…]

[hal-01761544] Potentially harmful elements in house dust from Estarreja, Portugal: characterization and genotoxicity of the bioaccessible fraction
Due to their behavioral characteristics, young children are vulnerable to the ingestion of indoor dust, often contaminated with chemicals that are potentially harmful. Exposure to potentially harmful elements (PHEs) is currently exacerbated by their widespread use in several industrial, agricultural, domestic and technological applications. PHEs cause adverse health effects on immune and nervous systems and can lead to cancer development via genotoxic mechanisms. The present study is an integrated approach that aims at assessing the genotoxicity of bioaccessible PHEs following ingestion of contaminated house dust. A multidisciplinary methodology associating chemical characterization of five house dust samples, extraction of the bioaccessible PHEs in gastric extracts by the unified BARGE method, determination of the bioaccessible fraction and in vitro genotoxicity of gastric extracts in adenocarcinoma gastric human (AGS) cells was developed. The five gastric extracts induced dose-dependent genotoxicity in AGS cells. Copper (bioaccessible concentration up to 111 mg/kg) was probably the prevalent[…]

[hal-01966568] Lead and zinc concentrations in household dust and toenails of the residents (Estarreja, Portugal): a source-pathway-fate model
This paper describes a methodology developed to assess and apportion probable indoor and outdoor sources of potentially toxic elements while identifying chemical signatures in the household dust collected from private homes in an industrial city (Estarreja, central Portugal). Oral bioaccessibility estimates and the chemical composition of toenail clippings were used to assess indoor dust ingestion as a potential exposure pathway and further investigate exposure–biomarker relationships. Indoor and paired outdoor dust samples were collected from each household. A total of 30 individuals, who provided toenail clippings and a self-reported questionnaire, were recruited for the study. Total concentrations of 34 elements, including lead and zinc, were determined in washed toenail samples and household dust via Inductively Coupled Plasma-Mass Spectrometry. The oral bioaccessibility was estimated using the Unified BARGE Method. The enrichment factor shows that lead was enriched (10

[tel-01787667] Transfert des éléments traces métalliques vers les végétaux : mécanismes et évaluations des risques dans des environnements exposés à des activités anthropiques
Les décharges de résidus riches en éléments traces métalliques (ETMs) issus des activités industrielles représentent un risque potentiel de pollution de l’environnement. Ces décharges de résidus exigent une stabilisation des ETMs pour limiter leur dispersion par l'air, le sol, et les cours d’eau, et in fine leur transport vers des zones initialement non contaminées. Cette stabilisation peut être obtenue par un couvert végétal adéquat. Ce travail de thèse a porté sur 3 sites expérimentaux, qui ont comme point commun d’être des zones de stockage de sédiments contaminés ou d’effluents industriels chargés en ETMs. L’objectif général de ce travail de thèse était d’étudier les modes de transfert et de stockage d’ETMs vers les parties aériennes de végétaux cultivés sur les sols issus de ces sites expérimentaux. Le premier objectif concernait une décharge d’effluents (Inovyn), issus de l’activité électrolytique de l’usine Solvay (Tavaux) et enrichi en Hg. Le Hg, en raison de[…]
