Evaluation of lead exposure using Achatina achatina (Linné 1758) at varying traffic intensity

Abstract

Ecotoxicological observations on Achatina achatina (Linné, 1758) were assessed for the bioaccumulation of lead in snail carcass as induced by traffic near abandoned battery factory (Niger Delta, Nigeria). Levels of lead bioaccumulation above European Commission limit of 1.5g/g at higher traffic intensity depressed (p<0.05) carcass weight. It is advised that consumers are at risk of chronic lead toxicity from snails exposed to environments of high traffic intensity.
