Comparison of plasma HCG, PCBs, DDE and dieldrin, and ethion levels in the three studied groups.
| G1 (n = 49) No previous abortion |
G2 (n = 26) Abortions less than 3 times |
G3 (n = 26) Abortions more than 3 times |

One-way analysis of variance (ANOVA) was used for comparison.
PCBs, plasma polychlorinated biphenyls; DDE, dichlorodiphenyltrichloroethane.
