摘要：The multivariate analysis of variance MANOVA was used to analyze the data obtained from this study. No significant difference was shown between the concentrations of all parameters during four seasons and all stations based on MANOVA test. The total percentage of DDE, Kelthane, -BHC, and DDT detected in stations were 63, 56, 50 and 69% over the year, respectively. The maximum concentrations of -BHC (fall), kelthane (fall), DDE (spring) and DDT (summer) were 21.6, 15.4, 9.8 and 9.2µg/l, respectively. The minimum concentrations of kelthane, -BHC, DDE and DDT were 3, 3.1, 1.9 and 3µg/l in stations 1 (summer), 2 (fall), 3 (summer) and 4 (summer), respectively. In this study, most of chemicals compounds were found in agricultural periods (spring and summer). During four seasons, the most percentage of chemicals compounds such as DDT (summer), -BHC (summer-fall), Kelthane (spring-summer) and DDE (spring) were 100, 75, 75 and 75%, respectively.
