对1997年至1999年期间出生于城市地区、受到五氯苯和六氯苯大量输入的4岁儿童进行的研究表明，血清中五氯苯酚的实测浓度可能主要是这些氯化碳氢化合物代谢的结果。相比之下，对同一化合物含量相对较低的农村儿童群体进行的研究表明，除了五氯苯和六氯苯的转化之外，其他投入也是造成五氯苯酚浓度测量值的原因。在这两个群体中，结果表明，这些儿童在4岁时血清中存在的有机氯化合物的主要比例是在哺乳期。(C)2007年爱思唯尔公司All rights reserved.
The study of a population of 4-year-old children born between 1997 and 1999 in an urban area under strong inputs of pentachlorobenzene (PeCB) and hexachlorobenzene (HCB) suggested that the measured concentrations of pentachlorophenol (PCP) in serum may essentially result from metabolism of these chlorinated hydrocarbons. In contrast, examination of a rural population of children where the same compounds were present at relatively low levels points to other inputs besides transformation of PeCB and HCB being responsible for the measured PCP concentrations. In both populations, the results showed that a major proportion of the organochlorine compounds present in these children's serum at 4 years of age was incorporated during the lactation period.
