Ce projet vise à développer, à partir d'études sociologiques comparées menées dans 2 sites industriels du ROHM du Labex DRIIHM, une réflexion interdisciplinaire sur les savoirs, les incertitudes et les ignorances à propos des risques environnementaux et sanitaires. L’objectif est de partir des données disponibles, et de résultats originaux produits à l'occasion d'un stage post-doctoral, pour identifier des différences et similitudes dans les modes d’appréhension et de prise en charge des pollutions dans deux territoires littoraux Sud-Européens. Nous ambitionnons ainsi de mieux comprendre les raisons qui poussent à taire ou bien publiciser les risques environnementaux et sanitaires induits par la pollution, selon les époques. Nous prêterons une attention toute particulière aux efforts de connaissance experts et profanes qui visent à documenter les effets des pollutions sur la vie quotidienne des populations concernées. Nous examinerons les perceptions tout autant que les contraintes qui pèsent sur les riverains et leurs engagements pour faire face aux risques. Nous nous poserons enfin la question de savoir comment rapprocher les partes prenantes pour ouvrir sur de nouvelles possibilités de surveiller et réguler les risques dans les territoires soumis à de fortes pressions anthropiques de manière concertée.

Chronic obstructive pulmonary disease (COPD) is a leading cause of mortality worldwide, particularly in low and middle-income countries. Historically, smoking has been identified as the leading cause of chronic obstructive pulmonary disease (COPD) in the world. However, exposure to other risk factors is increasingly being recognized as a possible cause of COPD. Indoor air pollution, for example, is one of those risk factors. The sources of indoor contamination might be derived from industrial activities and/or indoor activities such as biomass burning for cooking and heating.
About 3 billion people, half the worldwide population, are exposed to smoke from biomass fuel compared with 1.01 billion people who smoke tobacco, which suggests that exposure to biomass smoke might be the biggest risk factor for COPD globally. In populations with low smoking prevalence, such as women in developing countries, it is estimated that 80% of chronic bronchial obstruction cases are attributable to factors other than tobacco.
In this project, we intend to implement the RESPIRA project that is being developed in the highly industrialized area of Estarreja, Portugal, in Tessekéré, Senegal in order to study the contribution of exposure to biomass smoke to chronic pulmonary diseases. The results obtained with these twin projects will allow to better understand the role of the indoor environment on the development and progression of chronic obstructive pulmonary diseases in two countries with distinctive contamination sources and with different socio/economic and geographical characteristics

Environmental quality
Soil, an important environmental compartment, is largely affected daily by anthropogenic activities such as industries, traffic and waste disposal. These activities can bring to the soils large quantities of several contaminants and consequently they can easily enter the food chain and the trophic scale of ecosystems via plants and animals.
This type of organic pollutants can persist for long times in the environment, being susceptible to transport for long distances, then they can easily reach a large geographic area and be widely dispersed.
It is of an extreme importance to assess the environmental and human health risk pose by this problem. In this work, an evaluation and a comparison study will be done through bioavailability tests and ecotoxicological bioassays with plants and invertebrates in order to assess the real risk inherent to the presence of such pollutants in soils of an important industrial area: Estarreja (Portugal).

These constructions were responsible for significant changes in the sedimentation processes in the river banks especially during overflow episodes. Sediment deposition can lead also to several ecosystem and health risks once some inorganic and organic pollutants can be associated to these sediments.

isotopie du mercure
Les territoires des OHMs sont fréquemment concernés par des pollutions anciennes et actuelles. Ceci est particulièrement vrai pour les éléments trace métalliques comme le plomb, l’arsenic ou le mercure. Le projet RETROW utilise des archives environnementales dans 3 OHMs (Vicdessos, Estarreja et Nunavik) pour reconstruire les chronologies de la pression humaine en termes de pollution dans ces territoires. Les reconstructions combinant différentes archives comme les sédiments, tourbes, cernes d’arbre ou otolithes permettent de caractériser les niveaux naturels antérieurs aux pollutions ainsi que de reconstruire les chronologies de ces pollutions et leurs sources (traçage isotopique). La phase 2 a pour objectifs de compléter les acquis de l’an dernier ainsi que de développer de nouvelles approches comme les mesures isotopiques du plomb dans les tourbières du Nunavik ou bien les mesures de métaux dans les diatomées retrouvées dans les sédiments récoltés lors de la phase I de RETROW à Estarreja.

Air pollution
Toxic concentrations of potentially harmful elements in ambient air can lead to (1) hazardous impact of airborne PM in the health of the population and (2) contamination of water supplies, edible crops and human food supply.
Estarreja and Provence regions are impacted by industrials activities, road traffic and growing urbanization and their air quality degradation is a major issue in terms of health risks and environmental impact. Exposure to PM has been associated with respiratory symptoms, decreased lung function, worsening of asthma and the development of chronic bronchitis.
Considering that dust is the most important contributor for nonpoint source pollutants to aquatic and terrestrial systems, dust deposition data is relevant information to assess potential impacts on humans and ecosystems.
This multi-proxy study aims at correlating dust origin (using isotopes “fingerprints”) and physicochemical dust properties, to potential risks (magnitude of exposure and bioavailability) in terms of human health and environmental effect.

Environmental matrices
Organic pollutants
Environmental matrices such as soils, plants, superficial waters and aquatic organisms can be an indicator of the environmental pollution since they could contain high levels of organic pollutants (OPs) influencing the environment quality and consequently human health. OPs are resistant to degradation and can persist for long times in the environment. These compounds can be transported by wind for long distances and can also easily enter the food chain. People are exposed to OPs by ingestion, inhalation and dermal uptake, causing adverse effects in human health due to their carcinogenic and mutagenic nature.
The exposure risks to ecosystems and human health will be assessed and monitored on some environmental
matrices presents in Estarreja, a very important industrial zone. OPs bioavailability will be assessed and quantified through chemical extractions. Bioacessibility tests will be performed in order to infer about the OPs concentrations that can beincorporated by plants and organisms and eventually reach humans.
This study aims to contribute to a better insight on the behaviour of OPs in the ecosystems dynamics and infer about the real human exposure risks.
This research work will improve current scientific knowledge about the possible existent contamination by the
several OPs, risk assessment and environmental quality of Estarreja area. Assessment of the bioavailability of
pollutants and human health risks will be performed through: chemical extractions and also bioaccumulation,
bioaccessibility and ecotoxicological studies. It will give us new data about toxicity and bioavailability of present OPs. The main focuses are:
1. Analysis of the contamination levels presents in some environmental matrices (soil, plants, superficial waters and aquatic organisms) in Estarreja area;
2. Evaluation of contaminants bioavailability and bioaccumulation levels by using chemical extraction procedures and by evaluating the accumulation of OPs in plants and aquatic organisms;
3. Quantification of OPs bioaccessibility, namely through physiologically based extraction tests on soil, plants, superficial waters and aquatic organisms;
4. Integration of the obtained results in order toassess risks for human health by describing the contamination levels with OPs and their availability to be up taken by humans; at the end, soil and water quality will be linked to the global ecosystem health.
5. Contribute to define criteria for OPs contamination accepted levels based on potential health risks to humans and define protection strategies for this type of contamination.
