HALOGENATED PERSISTENT ORGANIC POLLUTANTS IN HUMAN BLOOD PLASMA FROM SANMING, SOUTHEASTERN CHINA
Human plasma samples collected in January 2008 from 86 blood donors residing in Sanming, southeastern China, were analyzed for halogenated persistent organic pollutants (H-POPs) including organochlorine pesticides (OCPs), polychlorinated biphenyls (PCBs) and polybrominated diphenyl ethers (PBDEs). The median values of HCB, ∑4HCHs, ∑4DDTs, ∑10PCBs and ∑15PBDEs were 31.6, 48.3, 1408, 12.4 and 2.5 ng/g lipid, respectively. Compared with the developed countries, such plasma H-POPs concentrations revealed relatively lower PCBs and PBDEs exposure levels, however, higher OCPs exposure levels in this general population in Sanming. The most frequently detected OCPs were p,p-DDE and β-HCH, accounting for greater than 82％ in DDTs and 66％ in HCH isomers, respectively. PCB153, 180, 138, 163 and 118 were predominant congeners determined, contributing more than 93％ of the ∑10PCBs. Four out of the 86 plasma samples (accounted about 5％) was found measurable BDE209 concentration (2.9-3.6 ng/g lipid), indicating potential pollution of commercial Deca-BDE. Correlation between H-POPs exposure levels and individual information such as age, occupation and gender were analyzed. Some kind of OCPs and PCBs were observed to correlate positively to human age. Relatioship between the plasma H-POPs levels and those in the environmental media and dietary intake is being investigated in our laboratory.
