Ana Rita Silva	2022	TERRA - Climate change impacTs in EstaRRejA region	climate change extreme events multiple climate factors contamination ecotoxicology.	Although great efforts have been made over the last years, climate change continues to impact our planet. According to IPCC predictions, atmospheric CO2 levels and mean temperature are expected to continue rising jointly with the frequency/intensity/duration of extreme weather events (e.g., droughts and floods). The impact of climate change may be exacerbated in metal(loid)-contaminated areas, such as the Estarreja municipality, where ecosystems have been under stress for decades. TERRA aims to understand the effects of climate change alterations on the terrestrial and aquatic ecosystems, using contaminated soils from Estarreja. For that, extreme climate events/predicted climate change scenarios (including changes in combined climate factors according to IPCC) will be simulated to evaluate their effects on the ecotoxicity in terrestrial and aquatic inhabitants. Moreover, soil/water properties, e.g. pH, metal(loid) content, soil organic carbon, will be evaluated to establish the link between soil/water properties and effects under changing climate factors. Considering that extreme climate events have been reported in the last years in Portugal, the project intends to understand the dynamics behind contamination in this region after these events, by evaluating contamination level in Estarreja region five years later (by comparing with previous works). TERRA will provide crucial data for Portugal and worldwide regarding the consequences of climate changes in contaminated areas. The present project will also promote an easy and active communication with the society, with the final aim of increasing awareness about climate change and its environmental impacts.

Nuno Durães	2022	TracEnviSoil - Tracing metal(loid) and rare earth elements contents in alluvial soils of Baixo Vouga Lagunar: Origin, availability and environmental issues	Alluvial soils Potential toxic elements REEs ecotoxicology essays bioaccumulation geogenic anthropogenic inputs	The Baixo Vouga Laugar (BVL) is a very particular example of the harmonious coexistence between man and nature. This region, characterised by highly productive soils, enticed humankind to take advantage of its land and surface water reservoirs for the development of various agricultural practices (e.g., rice paddies, cornfields, pasture, among others). The high fertility of BVL's soils is owed to their development under the influence of alluvial deposits, materials with loamy texture, high porosity and marked organic matter enrichment. However, as demonstrated by the results obtained in other OHM projects, some of these soils are enriched in several potential toxic elements (PTEs). For this reason, the TracEnviSoil project intends to obtain a screening of the distribution of metal(loid)s of greater concern, as well as of rare earth elements (REEs), in order to ascertain the most probable sources (geogenic versus anthropogenic) of these trace elements, but also their (bio)availability and eco-toxicity in agriculture soils. This would allow to infer the potential risks for soil productivity, by creating harmful conditions for the soil microbiome and plant growth. Finally, the bioaccumulation of PTEs in the edible parts of plants will be evaluated in order to estimate the risk of their entry into the food chain, namely of animals and humans that feed on the vegetable products grown on these soils.

Jean-Philippe Bedell	2017	Bioavailability and ecotoxicology assessment of organic contaminants presents in Estarreja soils	Ecotoxicology Bioavailability Mobility Risk assessment Organic pollutants Emerging contaminants Soils Earthworms Plants Environmental pollution 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).

Ecotoxicology Bioavailability Pollutants mobility Risk assessment Organic pollutants Emerging contaminants Soils Earthworms Plants Environmental pollution Environmental quality	Soil, an important environmental compartment, is largely affected daily by anthropogenic activities such as industries, traffic and waste disposal.

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) as well as in the“casiers Girardon” of Rhône river (France). 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.	OHM Estarreja OHM Vallée du Rhône		Afficher

Manuela Inácio	2015	Ecotoxicological and human health risk assessment of organic contaminants in Estarreja area – preliminary studies	Human health Ecotoxicology Risk assessment Environmental pollution Environment quality 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.	OHM Estarreja		Afficher
