Abstract
Racial stratification of residues of total DDT equivalent, heptachlor epoxide, oxychlordane, dieldrin, .beta.-benzene hexachloride and lindane in human adipose tissue was studied. Samples of human adipose tissue were obtained from locations selected in the contiguous USA according to a stratified, proportionate-random survey design and chemically analyzed for selected organochlorine pesticides. The most marked case of racial difference in residue level was total DDT equivalent. Negro samples contained almost twice as much of this chemical as Caucasian samples. Racial stratification was found in the frequency of lindane. Lindane was detected about twice as often in Negro samples than Caucasians. Little racial differences were noted for residues of .beta.-benzene hexachloride, heptachlor epoxide, dieldrin and oxychlordane.
