RESUMO
Objective To understand the body burden and the distribution characters of organochlorine pesticides and residues in non-occupational exposure population. Methods A cross-section study was conducted from Mar. 2004 to Jul. 2004, 107 men and 142 women, who were all healthy community residents, were investigated. Serum DDTs and HCHs level were determined by EC-ECD. The relationship between organochlorine pesticides in serum and age and BMI were analyzed by liner regression. Results Organochlorine pesticides and residues in serum with high detection rate were ?-HCH≥82.2%, p,p'-DDE≥94.4%, p,p'-DDT≥91.6%, and the level of the three organochlorine pesticides in the serum of women was significantly higher than that in men Mann-Whitney Test, P
