The Bung boraphet wetlands,Central Thailand. It is an important habitat of many species of birds, which is an area surrounding is a community made of agriculture and use of organochlorine pesticides (OCPs). OCPs are causing environmental problems due to the slow decomposition and accumulation in the food web, especially the birds there will opportunities and be a high risk to accumulate toxins. So sampling birds analyzed the accumulated toxins in the liver in contaminated food of birds around the bung boraphet. This will divide the birds by eating out 3 groups is a carnivorous birds, omnivorous birds and insectivorous birds. A sample of birds captured all 9 species, found that the carnivorous birds were a risk of accumulation by toxins highest, omnivorous birds were a risk moderate and insectivorous birds were a risk of toxins relatively low. However, this study suggests that bung boraphet wetland there continues to be contaminated with the OCPs from agricultural, which results in the study of the concentration of the OCPs are similar to previous studies. It is still agriculture area around the bung boraphet to control and limited the use of OCPs and should be used properly
