以长沙市望城区集中式饮用水源地一级和二级保护区周边0~20 cm土壤为研究对象,于2018年采用网格布点法在一级和二级保护区分别布设3个(1#~3#)和12个(4#~15#)采样点,其中11#~15#采样点于2014年布设,探究土壤中苊(Ace)、苊烯(Acy)、蒽(Ant)、菲(Phe)、芴(Flu)、苯并[a]蒽(BaA)、芘(Pyr)、屈(Chr)、荧蒽(Fla)、苯并[a]芘(BaP)、苯并[b]荧蒽(BbF)、苯并[k]荧蒽(BkF)、二苯并[a,h]蒽(DBA)、苯并[g,h,i]苝(BghiP)、茚并[1,2,3–c,d]芘(IcdP)共15种多环芳烃(PAHs)的污染水平及来源,运用毒性当量浓度值及终生癌症风险增量模型对土壤中PAHs进行风险评价。结果表明:水源地保护区土壤中15种PAHs总含量为75....

This study aims to investigate the pollution level and source of polycyclic aromatic hydrocarbons(PAHs) in the soil around a centralized drinking water source in Wangcheng district of Changsha, Hunan, China. The 0-20 cm soil in the first and second protection areas of the water source was taken as the research object. In 2018, three(1#-3#) and twelve(4#-15#) soil sampling points were arranged in the first and second protection areas respectively by the grid method, and 11#-15# soil sampling points were arranged in 2014. Fifteen varieties of PAHs including acenaphthene(Ace), acenaphthylene(Acy)...
