| Abstract | The utilization of endosulfan for pest control has caused problems to the environment due to its persistent nature. In this research, two sites in Suphanburi Province, Thailand were selected for study, namely: Amphoe Sam Chuk (contaminated site) and Amphoe Nong Yai Sai (control site). Concentration of endosulfan residues at the depth 0-15 cm and 15-30 cm at contaminated site were around 0.017-0.678 ug/kg and 0.016-2.132 ug/kg, respectively. At the control site, concentration of endosulfan residues at the depth 0-15 cm and 15-30 cm were around 0.3- 7 ng/kg and 3.2-15.8 ng/kg. Endosulfan residues in water were around 0.006-0.285 ug/L. Solid phase extraction was used as cleaning process after sample extraction. Percentage recovery of α, β endosulfan and endosulfan sulfate in soil samples ranged from 81%-90% at 0.5 ppm and 1 ppm. Percentage recovery in water samples ranged from 82%-89%. From fugacity calculation, fugacity of α endosulfan was the highest as 6.24x10⁻⁷ Pa. β endosulfan and endosulfan sulfate was lower as 5x10⁻⁸ and 2x10⁻⁹ Pa which meant that αisomer can transport to other compartment easier. Fugacity capacity and concentration of endosulfan was very high in biota which up to 18.84 ug/kg. Consequently, endosulfan can accumulate and remain in fatty tissue for a long time. |
