  • Some pesticides and PCBs continue to be reported as environmental problems in some areas of Vietnam. In 2005, a study among delivering women took place in two communities in south-central Vietnam (Khanh Hoa Province), namely the coastal city of Nha Trang and the rural district of Dien Khanh located about 10 km inland. The main findings in plasma (n=189) were relatively high mean concentrations of p,p'-DDE (12.2 microg/l in Nha Trang and 11.4 microg/l in Dien Khanh) and p,p'-DDT (1.2 microg/l in Nha Trang and 1.1 microg/l in Dien Khanh) with no significant community differences. The ratio of p,p'-DDE/p,p'-DDT (11.5 in Nha Trang/12.7 in Dien Khanh) suggests, as in other Vietnamese OCs studies, a relatively recent use of this pesticide. Mean concentrations of PCB 153 (0.15 microg/l in Nha Trang and 0.10 microg/l in Dien Khanh) and other congeners were low in both communities. Age and parity (all compounds), as well as community of residence for PCB 153, were the most important predictors of plasma OCs concentrations.
