The prior 16 kind of PAHs in pollutants controlled by the US EPA have been analyzed with gas chromatography(GC) in the water sample from Dongwushi Reservoir in Handan,and 7 kind of PAHs are detected with a total mass concentration of 7.28μg/L.The high molecular weight PAHs with 4 and 6 benzene rings predominate in PAHs components with 79.6 percent,much more than the low molecular weight components.Among them,benz(a)anthracene accounts for 51.8 percent,benzo(g,h,i)perylene does 15.8 percent,and others else from more to less are phenanthrene,indeno(1,2,3-cd)pyrene,benzo(b)fluoranthene,fluorene and fluoranthene,respectively.Such distribution suggests that PAHs in the Reservoir water derive mainly from pollution of incomplete combustion of coal,and lesser from the drainage of coal mine.The high concentration of total PAHs and members indicates that an evident PAHs pollution has occurred in the water body,and in all probability brings potential ecological risk to the environment,to which the people and local government ought to pay much more attention.
