Resumo(s)
This study assesses water quality in the Portuguese section of the Douro River basin (Bragan & ccedil;a region, NE Portugal) by evaluating the presence and potential impact of pharmaceutical contaminants (PhCs), classified as contaminants of emerging concern (CECs). A set of 65 pharmaceuticals was investigated for their occurrence and ecological and health impact. The extent of contamination by these compounds, and its possible effects on the aquatic ecosystem was analyzed and discussed. Additionally, the accumulation of these pharmaceuticals in sediments is investigated, providing a more comprehensive understanding of their distribution and persistence in the environment. Out of these 65 CECs, 23 were found in water and 10 in sediments. The most abundant correspond to acetaminophen, diclofenac and ibuprofen. The data obtained are used in this paper to develop an environmental indicator system, which serves as a valuable tool for assessing ecosystem health and water quality. This system provides key information to support decision-making regarding environmental management and conservation. Ultimately, this integrated approach aims to enhance the understanding and protection of water resources in the Bragan & ccedil;a region and beyond.
