Abstract
The aim of the work is to study the accumulation of organochlorine pesticides, polychlorinated biphenyls and heavy metals in the soft tissues of commercial bivalves from continental reservoirs of the south Vietnam and to assess health risks for population.
Materials and methods. Four genera of bivalves from the Mekong Delta Corbicula sp., Geloina sp., Ensidens sp., Scabies sp. were studied. Organic pollutants were determined by gas chromatography-mass spectrometry, heavy metals by atomic absorption in flame and flameless atomizers. Health risks were assessed by determining the hazard quotient (HQ) and the incremental lifetime cancer risk (ILCR).
Results. To minimize the risk of poisoning when consuming Corbicula sp., Geloina sp., Ensidens sp. and Scabies sp. maximum consumption levels should be 83, 15, 1 and 6 pcs/day, respectively. The risk of developing cancer can be increased with the consumption of Corbicula sp. Ensidens sp. and Geloina sp. in an amount of 212 pcs/day.
Conclusion. The maximum consumption levels of four bivalves genera were determined, at which there is no health risks for the population of South Vietnam. All risks are associated with -HCH, PCBs, Mn and Fe. Safety assessment of local food (in particular, not traditional for tourists) is an urgent task to ensure the safety of life and health of Russian citizens abroad.
