Water, Environmental and Food Chemistry (ENFOCHEM)

This Unit focuses its research on the presence, impact and fate of organic pollutants in the water cycle, terrestrial environment, biota, food and humans, including not only those that are regulated in the legislation (priority contaminants), such as pesticides and polycyclic aromatic hydrocarbons, but also contaminants of recent identification (contaminants of emerging concern), such as pharmaceuticals, personal care products, drugs of abuse, for which environmental occurrence and ecotoxicity data are very scarce. This involves their monitoring in field samples and assessment of their degradation/metabolism in different types of water matrices, particulate matter, sediments, soils, sewage sludge, air, aquatic organisms, crops, food and biological samples from humans. It further deals with the bioaccumulation of contaminants in biota and humans. This research line has a long history of monitoring activities, which have been carried out in very diverse areas, going from remote areas (for instance, the Antarctic) to local rivers. The research group has broad experience in coordinating national and international research projects funded by the European Commission, other International Institutions, and the Spanish Government. In addition, it has many contracts with public and private entities (e.g. Catalan Water Agency-ACA and Sociedad General de Aguas de Barcelona -AGBAR).
