For the first time, the bivalve mollusc Colletopterum ponderosum sedakovi (Siemaschko, 1848) was used as a universal bioindicator of pollution of Lake Baikal ecosystem with organochlorine pesticides (OCPs). OCPs were identified and quantified in soft tissue samples, collected from Lake Baikal. Dichlorodiphenyltrichloromethylmethane (DDT) and its metabolites, isomers of hexachlorocyclohexane (HCH) and hexachlorobenzene (HCB) were identified using modern gas-chromatography-mass spectrometry. The obtained data on OCPs levels have been compared with those reported earlier for molluscs from other world regions. Levels, sources and trends of OCPs contamination of Lake Baikal ecosystem and its basin were established. The recommendations on using Colletopterum ponderosum sedakovi as a bioindicator of OCPs in aquatic ecosystems in further research have been proposed. © Published under licence by IOP Publishing Ltd.
