At the present study, the environmental pollutants such as organochlorine pesticides (OCPs), heavy metals (during three seasons) and surfactants (during four seasons) were done 2009 to 2010 that located in Mangol Dam with longitude and latitude 52° 22' 49" N and 43° 15' 43" E, respectively. The aims of this study were to determine the seasonal pollutants matters in water samples of under-groundwater and surface water in 12 stations and the results are as follow: The maximum residues fluctuations of OCPs were determined in between all water samples such as aldrin and endrin about 1.51 and 2.85 µg/l, respectively. The mean concentration of aldrin and endrin about 0.66 ± 0.59 and 0.71 ± 1.07 µg/l, respectively were determined. The maximum seasonal concentration of OCPs were detected in fall, winter and spring for such as endosulfan sulfate, γ-BHC, heptachlor, endrin aldehyde compounds about 2.85, 0.34, 0.14 and 0.14µg/l, respectively. The maximum seasonal percentage range of OCPs were detected in fall, winter and spring in water samples such as endosulfan sulfate, DDD and β-BHC were 42, 25 and 25 %, respectively. The maximum seasonal concentrations of Zn and Fe elements were detected in spring about 1.12 and 8.22 µg/l, respectively. Also for Hg in spring was determined about 17.2 mg/l. The mean concentration of Zn, Fe and Hg in water sampled were 0.23 ± 1.01 and 1.21 ± 2.00 µg/l, respectively and 4.65± 6.38 mg/l. The maximum seasonal percentage range of heavy metals were detected in fall, winter and spring in water samples such as Ni, Zn and Fe were 66, 83 and72%, respectively. The maximum seasonal concentrations of heavy metal were detected in Sorkhroud and Polechelave stations during fall, winter and spring for only Fe about 1.48, 3.3 and 8.22 µg/l, respectively. The maximum concentration of linear alkyl benzene sulfonate (LAS) in last month of summer was 971µg/l. The mean concentration of surfactant during fall, winter , spring and summer was 418.62 ± 52.16 µg/l. The maximum seasonal percentage range of surfactant uring fall, winter, spring and summer in all stations of sampling were 76, 76, 100 and 100 %, respectively.Pages
