Cau Hai lagoon, located to the south of Phu Loc District, Thua Thien Hue province and the part of the Tam Giang - Cau Hai lagoon system is one of the largest lagoon systems in Southeast Asia. Cau Hai lagoon is a waterbody receiving overflowing water from the inland rivers and streams, so it is possible to accumulate organochlorine pesticides (chlorinated organic groups) in sediments. This study used Gas Chromatography-Mass Spectrometry (GC/MS) method to investigate the content of some organochlorine pesticides in sediment samples. In general, the results showed the presence of some organochlorine pesticides in the sample such as α-HCH, β-HCH, δ-HCH, Heptachlor, Aldrin, Heptachlor epoxide and Endosulfan. Some toxic chemicals had concentration less than the limit of detection of the analytical method. The results of this research showed the scientific and practical significance, which is an important database for concentration of organochlorine pesticides in sediment of Cau Hai lagoon, Thua Thien Hue province, Central Vietnam.
