The samples'concentration level is ng/L, meanwhile, which doesn't go beyond the national standard "Environmental quantity standards for surface water-GB 3838—2002"and "Drinking water quality criteria standard GB5746-85". The study shows that the water purification palnts in The Three Gorges Reservoir Area especially those raw water from Yangtze River and Jialingjia River is safe enough for drinking and its level is low.

Of which, naphthalene, fluoranthene and DEHP are priority pollutants firstly listed by SEPA..
