Problems bioaccumulation and Biomagnification

Detection the presence of frequently used pesticides in fish collected from Tonle Sap lake in Cambodia Target compounds : 65 POPs – Organochlorines (OCPs) – Polychlorinate biphenyls (PCBs) – Bis-(p-chlorophenyl) sulfone (BCPS) – …… Objective of Study

Sampling sites : Siem Reap, Pursat, K. Thom, K. Chhnang 76 fishes collected 36 samples analyzed -12 (12 species)from Siem Reap -15 (12 species)from Pursat -4 ( 4 species) from K.

Conclusion Trace of dangerous compounds are detected in Tonle Sap fish Predominant compounds are p,p’-DDT, PCBs and BCPS. Concentration of each compound is variable from one site to another These compounds are bioaccumulated and biomagnified it may affect to the people. Limit use of dangerous pesticides by educating users about its hazard Monitor residue frequently of pesticides in ecology system
