中文摘要:
      采用气相色谱法对邯郸市东武仕水库水样进行了16种EPA优控多环芳烃(PAHs)的定量分析,共检测出7种PAHs单体,总质量浓度为7.28μg/L。PAHs组成以4环和6环的高分子量PAHs为主,占总含量的79.6%,远大于低分子量组分。其中苯并(a)蒽占总量的51.8%、苯并(g,h,i)北占15.8%,其它依次是菲、茚并(1,2,3-cd)芘、苯并(b)荧蒽、芴和荧蒽。水库水体PAHs主要源于煤炭的不完全燃烧排污,其次是矿井排水。结果表明,PAHs总浓度和各单体浓度均较高,存在明显的多环芳烃污染,可能会对当地环境产生潜在的生态风险,应当引起人们和有关部门的高度重视。
英文摘要:
      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.
