介质分配系数预测二恶英类物质潜在蓄积趋势研究

摘要

The international environment protection policy is to identify and control thesources of some chlorinated organic compounds including polychlorinateddibenzo-p-dioxins（PCDDs）and polychlorinated dibenzofurans（PCDFs）,oftenknown collectively as dioxins.This study aimed to assess the transportation tendencyof dioxins and predict locations at high risk for dioxin pollution.For this analysis,newparameter,compartment distribution coefficient（Dc）,was created to account for thetendency of dioxins to preferentially accumulate in particular compartments.It wasobtained by proposed model combined with the mixture levels of PCDD/Fs in fourcountries:Japan,the United States,the United Kingdom,and Australia.
