Emerging Organic Contaminants in Chinese Surface Water: Identification of Priority Pollutants
نویسندگان
چکیده
The occurrence and impacts of emerging organic contaminants (EOCs) in the aquatic environment have gained widespread attention over past two decades. Due to large number potential contaminants, monitoring campaigns, treatment plants, proposed regulations should preferentially focus on specific pollutants with highest for ecological human health effects. In present study, a multi-criteria screening approach based hazard exposure potentials was developed prioritization 405 unregulated EOCs already Chinese surface water. Hazard potential, risk quotients effects were quantitatively analyzed used screen contaminants. defined by contaminant persistence, bioaccumulation, ecotoxicity, effects; similarly, function concentration detection frequency. total, 123 compounds passed preselection process, which involved priority index equal normalized multiplied potential. Based scheme, 11 identified as top-priority, 37 chemicals high-priority. results obtained compared four other schemes or health. effectively captured integrated from more simplistic schemes. data gaps, uncertainty categories classified recommend: ? regular monitoring, derivation environmental quality standards, development control strategies; ? increased monitoring; ? fortified assessment; ? efforts collect toxicity data. Overall, 20 recommended EOCs. prioritized list provides necessary information authoritative monitor, control, evaluate, manage risks environmentally-relevant

متن کاملEmerging chemical contaminants in water and wastewater.
Recent advances in environmental analytical chemistry have resulted in an explosion of knowledge regarding the presence of previously undetectable chemical contaminants in water and wastewater. Many of these contaminants are anthropogenic, resulting from commercial products from human society and subsequently dispersed throughout the aquatic environment, passing between wastewater effluents, na...
