Polychlorinated biphenyls in the human adipose tissue and liver samples of Bombay

Abstract
Of the seventeen samples of human adipose tissue and seven samples of human liver analysed for PCB, all were found to contain PCB. The adipose tissue showed mean PCB concentration of 0.920 ppm and the PCB contamination ranged from 0.206–2.843 ppm. On the other hand, liver samples were found to contain mean PCB concentrations of 0.403 ppm and the contamination of PCB ranged from 0.111–0.747 ppm. The analysis of PCB was done on a gas Chromatograph equipped with electron capture detector. The extraction of samples was done with hexane followed by clean up on a silica gel column.
