Body Burden Reductions of PCBs, PBBs and Chlorinated Pesticide Residues in Human Subjects
Ambio, Vol.13, No.5-6, 1984.
Summary: Prior to Narconon detoxification, adipose tissue concentrations were determined for seven individuals accidentally exposed to PBBs. The chemicals targeted for analysis included the major congeners of PBBs, PCBs and the residues of common chlorinated insecticides. Of the 16 organohalides examined, 13 were present in lower concentrations following detoxification. Seven of the 3 reductions were statistically significant; reductions ranged from 3.5 to 47.2 percent, with a mean reduction among the 16 chemicals of 21.3 percent (s.d. 17.1 percent). To determine whether reductions reflected movement to other body compartments or actual burden reduction, a post-treatment follow-up sample was taken four months later. Follow-up analysis showed a reduction in all 16 chemicals averaging 42.4 percent (s.d. 17.1 percent) and ranging from 10.1 to 65.9 percent. Ten of the 16 reductions were statistically significant.
