Ten human milk samples, collected from two towns, Uppsala and Sundsvall, in Sweden in 1994 were analysed for selected chlorinated pesticides (HCB, alpha-and gamma-HCH, DDT, DDD and DDE) and PCB congeners (PCBs 28,77,101,105,118,126,138,153,156,158,167,169 and 180), PCDDs and PCDFs.
The levels found in this study, including the toxic equivalent (TEQ) values, showed a slight downward trend between 1986 and 1994 and are somewhat lower than levels reported from other countries.
The contribution of both the mono-and non-ortho PCBs, together with that of PCDD/Fs to the total TEQ values was assessed.
Over 70% of the TCDD equivalents was derived from PCBs, PCB 126 being the major contributor.
Other high PCB contributors were PCBs 156 and 118.
The levels of HCB, alphaand gamma-HCH, and sigmaDDT were generally higher in Uppsala than in Sundsvall.
They were, however, over 50% lower in 1990 than in 1986 and have since changed little.
For the PCDD/Fs the results show a marked decrease (ca 50%) in levels between 1986 and 1994.
There is an indication that PCB 153 and PCB 126 may he good indicators for total PCB and TEQ levels respectively.
