Evaluation of Residual Amounts of Persistent Organic Pollutants and Traces of Heavy Metals in King Talal Dam.

摘要

ABSTRACT In this study, concentrations of different persistent organic pollutants(POP's) and heavy metals in samples from King Talal Dam (KTD) were investigated. The levels of PAH's were in the range from below the detection limit of 1 ng/l to 120 ng/L for water samples and from below the detection limit of <1 mg/kg to 23 mg/kg(dry weight) for sediment samples. From the 15 chlorinated pesticides studied in this work, Alpha and Gamma hexachlorocyclohexanes (-, - HCH) were frequently detected in .
