Organochlorine pesticides and polybrominated diphenyl ethers in giant African snail from the Niger Delta, Nigeria: Implications for dietary exposure and health risk assessment.

The concentrations of organochlorine pesticides (OCPs) and polybrominated diphenyl ethers (PBDEs) were evaluated in snails from different locations in the Niger Delta of Nigeria to provide data about their sources and possible risk to humans from the consumption of snails. The OCP and PBDE concentrations in snail samples ranged from 0.31 to 12.
