黄河头道拐段冰封期PCBs的分布特征及来源分析
Distribution and Source Analysis of PCBs in Ice Water During the Frozen Period at the Toudaoguai Section of Yellow River
摘要
Abstract
This study was conducted on basis of the measured data of polychlorinated biphenyl content in ice water during the frozen period,at the Toudaoguai section of Yellow river in 2012-2013.The distri-bution characteristics of polychlorinated biphenyl content and its origins were analyzed at this specific sec-tion in the frozen period.Results showed that:the ΣPCBs concentration in water is 10.19~53.00 ng· L-1 ,and the average concentration is 3 1.87 ng · L-1;the ΣPCBs concentration in ice is 2.9 1 ~34.34 ng·L-1 ,and the mean one is 15.1 1 ng·L-1 ,the content of Low PCB is larger than the High PCB,which is in consistence with the practical situation that Low PCB was massively produced and used in our country.Compared to the corresponding period in 201 1 -2012,the content of Low PCB was in-creased by 65.7%,but,the High PCB one was lowered by 20.39%,the general content was enlarged by 28.96%.The PCBs content in Flow Ling period is the maximum one,and it becomes smaller and smaller in the frozen period,while depicts a slight inclination of increase in the Ice Melting period.The origins of PCBs in ice water during the frozen period are:electric insulating oil,paint additive and Bleaching industries.关键词
