In this study, organochlorine pesticides (OCPs) and polychlorinated biphenyles (PCBs) levels were determined in 100 human milk samples from the city of Antalya. The levels of seven major PCB congeners; 28, 52, 101, 118, 138, 153, 180 and nine OCPs, alpha-HCH, beta-HCH, gamma-HCH, HCB, heptachlor epoxide, p.p'-DDT, p,p'-DDE, endosulfan-alpha and endosulfan-beta were determined by gas chromatography with ECD detection. The levels of analyzed compounds were as follows: I PCBs pound 27.46 +/- A 11.58, I DDT pound 1,407 +/- A 123, and I BHC pound 160 +/- A 490 ng/g lipid wt.basis. PCB 153 and p,p'-DDE were the dominant contaminants. The results have been discussed and compared with similar studies from other regions of Turkey.
