“…It has previously been reported [1,2] that freshwater invertebrates bioaccumulate cations from the environment. Additionally, it is also possible and worthwhile to employ features such as behavioral effects as sensitive markers/monitors of environmental toxicity/health [3][4][5] and such studies may create baseline data for assessing effects of such pollutants on human populations.…”

Studies in Cumbria (United Kingdom [UK]) [6], Hungary [1], and Nottinghamshire (UK) [2] have demonstrated that differences in the concentrations of specific cations in gastropods correlated with local differences in environmental pollution.…”

Snails (Lymnaea peregra) were exposed to both low and high concentrations of copper(as copper nitrate) undercontrolled conditions and then were sacrificed and dissected; various tissues/organs were removed and subsequently analyzed by atomic absorption spectrophotometry to determine both the copper concentration and the nature of localization. At low concentrations, bioaccumulation was evident in various tissues/organs; a dose response occurred in tissues derived from both the head and foot. At high concentrations, the copper concentrations of the liver-like body and kidney became massively enhanced. There was some variability in the ranking of tissues/organs with regard to copper bioaccumulation--this was predominantly linked to the copper concentration to which the snails were exposed. Mechanisms of copper bioaccumulation are reviewed and comparisons with other organisms made.

Heavy Metal Concentrations in Water, Sediments and Mollusc Tissues

The highest concentrations of heavy metals (Cu, Pb, Zn, Mn, Co, Ni, Cd, and Cr) were found in water, sediment and molluscs of the Malkø Bay and the Smeltelë River. It was determined that after dredging the toxic sediment there was a noticeable decrease of heavy metals in sediment and molluscs from the Malkø Bay. However, low concentrations of heavy metals were found in the Vilhelmo Channel near Klaipëda waterworks. In the same channel near Dreverna the concentrations of heavy metals were much higher and that was associated with the presence of silt in the sediment. This study shows that bioaccumulation of heavy metals in mollusc tissues is dependent not only on their concentration in water but on many other factors as well.

“…Lymnaea sp. also are good candidates for use as sentinel organisms, particularly in environments contaminated with metals [8]. When combined with laboratory tests and impact assessments of natural populations, active biomonitoring constitutes a critical component of a weight‐of‐evidence approach to assess effluent impacts [9].…”

We used a freshwater gastropod, Lymnaea palustris, in chronic bioassays to assess the toxicity of an industrial effluent containing high levels of metals, particularly Cr, Zn, and Fe. Adult snails were exposed for four weeks to different concentrations of effluent sampled at three successive treatment steps (crude effluent, effluent after physicochemical treatment, and after biological treatment). Dose-dependent responses reflecting exposure (metal bioaccumulation) and effects on survival, fecundity, and malondialdehyde production (a proxy for oxidative stress) were investigated. We found that Cr and Zn were accumulated in snail tissues, whereas Fe was regulated. Body concentrations of Cr and Zn decreased along the effluent-treatment gradient, particularly after the physicochemical treatment. For controls versus treatments, no effect on malondialdehyde production was detected. Significant effects were noted for fecundity. The number of eggs per individual decreased for snails exposed to 20, 30, and 40% concentrations of physicochemically treated effluent and for snails exposed to an 80% concentration of the biologically treated effluent. A hormetic effect on the number of eggs per individual was observed for snails exposed to 10 and 20% concentrations of the effluent that had been biologically treated. Deleterious effects of the effluent on L. palustris fecundity were not correlated with high internal concentrations of metals in the snails, suggesting that toxicity resulted from other factors.
