| pubmed-article:9577934 | pubmed:abstractText | Breast milk fat concentrations of three cyclodiene insecticides--dieldrin, heptachlor epoxide, and oxychlordane--were measured in 797 primiparous women, and sources of exposure that contributed significantly to high body burdens were investigated. All three distributions were highly skewed to the right, with median concentrations falling between 0.007 and 0.039 mg/kg. Termite control of residence was associated consistently with being in the high-body-burden group for all three compounds, but the association was greatest for heptachlor. Age, socioeconomic status, residential area, smoking, and home use of insecticides were also associated with high body burden of one or more of the compounds, but the odds ratios were lower than those for termite control; the findings were inconsistent for the three compounds. The results for termite control remained statistically significant when we adjusted for the other factors; therefore, termite control of residence is an important risk factor for cyclodiene insecticide absorption. | lld:pubmed |
