Abstract

The residual characteristics of HCHs and DDTs in park soils and dusts in Ulaanbaatar, Mongolia were determined by GC-ECD to evaluate their potential pollution risk. The residual concentrations of total HCHs and DDTs in the park soil samples were ranged in 11.36-53.14 ng·g-1 and 11.96-24.70 ng·g-1 while it was ranged in 32.28-92.68 ng·g-1 and 13.45-24.41 ng·g-1 in the park dust samples, respectively. We have studied the ratio of α-HCH/γ-HCH in order to determine pollution sources which may come from either technical HCHs or lindane. The study revealed that concentration of DDTs in soil has direct correlation on usage rate of the dicofol and technical DDT in the sampling area. The soil pollution assessments based on the single pollution index of HCHs and DDTs indicated that Ulaanbaatar city’s park soil and dust were not polluted with these compounds.The single pollution index of HCHs reached to 1.85 in A park dust samples,indicating the park dust environment was potentially polluted.
