The presence of organochlorine pesticide in Semarang indonesia marine waters and their contamination on green mussel Perna viridis (bivalvia: Mytilidae, linnaeus, 1758)

Abstract

This article present the existence of organochlorine contamination in marine waters of Semarang and their contamination on green mussel Perna viridis in Tambak Lorok coastal waters Semarang. The samples of green mussel Perna viridis and water sample were collected from mussel cultivated area. Five compounds organochlorine pesticide residues (OCPs) such as Heptachlor, Aldrin, Endosulfan, Endrin and pp-DDT of contaminant have been determined in the marine waters and mussel tissue. The samples were analyzed by using gas chromatography and followed by using the method of Standard Method Examination. The result of average concentration organochlorine pesticides in marine waters showed that the Heptachlor, Aldrin, Endosulfan, Endrin and pp-DDT were 20.68 µg/L, 1.88 µg/L, below detected, bellow detected, bellow detected, respectively. The high concentration of pesticide showed on Heptachlor (20.68 µg/L). On the other hand OCPs Heptachlor, Aldrin, Endosulfan, Endrin and pp-DDT in green mussel shows 140.48 µg/L, 49.04 µg/L, 28.38 µg/L, 155.13 µg/L, 116.14 µg/L. The result shows OCPs in green mussel tissues has higher concentration depend on marine waters, so that it indicates that green mussels had accumulated OCPs on their tissue.
