Project description

The discharge of high amounts of aquaculture effluents is one of the major factors influencing the quality of Hainan coastal waters and may lead, together with riverine input of municipal sewage and pesticides from agriculture, to the massive input of organic contaminants to coastal waters. Especially lipophilic organic contaminants are accumulated in aquatic biota and some contaminants such as antibiotics or pesticides from aquaculture effluents may pose a threat to species which are vital for the proper functioning of the coastal ecosystem. Nevertheless, a chemical characterization of organic contamination in Hainan coastal waters is missing which considers priority pollutants such as antibiotics and further, rarely observed “emerging contaminants”, which might be site-specific and also (eco)toxicological relevant. Therefore our major goal is to characterize and trace the input of land-derived organic contaminants to Hainan coastal waters as a basis to investigate associated potential effects on the coastal organisms.
