tailieunhanh - Evaluation of the accumulation of Organochlorine pesticides (OCPS) in fish Bostrychus Sinensis growing the Soai Rap estuary, Ho Chi Minh city
This study was conducted from May to November 2017 to evaluate the accumulation of organochlorine pesticide chemicals (OCPs) in fish, Bostrychus sinensis, growing at the Soai Rap estuary, Ho Chi Minh City, Vietnam. The pesticide chemicals in the tissues of fish and the sediments of the estuary were analyzed using a gas chromatography method and Varian GC-450 (ECD) instrument. The results showed that in all tissue samples of fish, the content of DDTs was the highest ( ng/g), followed by aldrin ( ng/g); HCHs ( ng/g); dieldrin ( ng/g) and endosunfans ( ng/g), and the lowest values were Heptachlor ( ng/g) and Eldrin ( ng/g). The content of OCPs in all sediment samples from the study area was found to be lower than Vietnamese standard 43: 2012 /MONRE and some other standards in the world. The bioaccumulation factor of OCPs in the tissue of fish was very low level (BAF DDTs > Aldrin > HCHs > Endosunfans > Heptachlor > Endrin. | Evaluation of the accumulation of Organochlorine pesticides (OCPS) in fish Bostrychus Sinensis growing the Soai Rap estuary, Ho Chi Minh city
