Résumé
Historical contamination from the Estarreja Chemical Complex is the central theme of OHMi Estarreja. Although extensive information exists on soil, water, and air contamination, key knowledge gaps persist, particularly regarding long-term risks and contaminant dynamics. Sampling has been episodic, with temporal gaps that hamper a trend analysis and evaluation of remediation processes. Sentinel species, which could serve as integrative bioindicators or proxies for human exposure, have been also largely overlooked. The R5-OHM project aims to: i) broadening analyte–matrix coverage (arsenic, methylmercury), ii) harmonizing sampling to reduce temporal discontinuities, iii) introducing sentinel species for long-term monitoring, and iv) co-creating a user-friendly fact sheet for sustained contaminant trend tracking. These objectives will improve understanding of exposure pathways, from the water–soil system through food to animal. A central component of the R5-OHM it is community engagement and knowledge return. By analysing materials sourced directly from residents’ properties, the project strengths local trust and returns decision-making power to the community, in line with the 2025 OHM theme of restitution. At the project’s conclusion, guidance will be developed on sampling frequency, matrix selection, and optimal sentinel species, culminating in a cost-effective, reproducible monitoring protocol for future OHM follow-up studies. The protocol will focus on two matrices, such as cow milk or leafy greens, with recommended sampling schedules for long-term trend analysis. The collection of local products and delivery of tailored fact sheets will involve direct engagement with households and farmers, translating scientific results into clear and easily accessible information. Demonstration plots will provide hands-on examples to reinforce recommended practices.
