“…First, because C. nemoralis snails lay their eggs in a nest in the soil (Heller 2001). Second, because uptake from the soil via soil feeding or through the skin is another route of metal transfer to snails in addition to uptake from the food (Coeurdassier et al 2002). Both U. dioica and G. aparine plants were collected in order to use as food.…”

Heavy metal pollution affects consumption and reproduction of the landsnail Cepaea nemoralis fed on naturally polluted Urtica dioica leaves

et al. 2006

This study is one of the very first that investigates the effects of heavy metal pollution on food consumption and reproduction of terrestrial snails under semi-realistic field conditions. Two experiments were carried out using snails (Cepaea nemoralis) and food (Urtica dioica leaves) from different metal polluted locations and one reference location. The first experiment showed that both polluted and reference snails fed on high-metal leaves from a highly polluted location had significantly lower consumption rates than snails consuming leaves from the reference location. In the second experiment, snails from both locations used in the consumption experiment and from two low-polluted locations were kept on native soil and food in order to reproduce. No negative effect of heavy metal pollution on clutch size was found for the snails from the reference location and the low-polluted locations. Snails from the highly polluted location laid no eggs. This suggests that at high levels of metal pollution, reproduction is strongly negatively affected. We suggest that the absence of egg laying by snails from the highly polluted location results from a combination of decreased consumption and an increased demand of energy for the accumulation and detoxification of metals (decreased scope for growth).

“…Snails take up metals from the food and, to a lesser extent, through the skin (Dallinger et al 2001;Coeurdassier et al 2002). The amount of food consumed and the metal concentrations in the food, amongst others, influence metal uptake and accumulation in the snails' body (Dallinger et al 2001).…”

“…Collembola, which live in airfilled pores in the soil and in the litter layer on top of the soil, can accumulate metals both from the water phase of the soil, from the soil itself and from food (Pedersen et al 2000). Snails accumulate metals from soils primarily from digestive but also from cutaneous routes of exposure (Coeurdassier et al 2002) and though most uptake of metals such as Cd is from the labile pool, a small portion of their uptake can be from the nonlabile pool via digestive processes (Scheifler et al 2003). Earthworms, commonly used as test organisms to determine the toxicity of metalcontaining soils (Hellin et al 2000), move material through soil and can also change the chemical species of some metals via their digestive processes (Naftel et al 2002).…”

Ecological risk assessment (ERA) of inorganic metals and metalloids (metals) must be specific to these substances and cannot be generic because most metals are naturally occurring, some are essential, speciation affects bioavailability, and bioavailability is determined by both external environmental conditions and organism physiological/biological characteristics. Key information required for ERA of metals includes: emissions, pathways, and movements in the environment (Do metals accumulate in biota above background concentrations?); the relationship between internal dose and/or external concentration (Are these metals bioreactive?); and the incidence and severity of any effects (Are bioreactive metals likely to result in adverse or, in the case of essential metals, beneficial effects?) -ground-truthed in contaminated areas by field observations. Specific requirements for metals ERA are delineated for each ERA component (Hazard Identification, Exposure Analysis, Effects Analysis, Risk Characterization), updating Chapman and Wang (2000). In addition, key specific information required for ERA is delineated by major information category (conceptual diagrams, bioavailability, predicted environmental concentration [PEC], predicted no effect concentration [PNEC], tolerance, application [uncertainty] factors, risk characterization) relative to three different tiered, iterative levels of ERA: Problem Formulation, Screening Level ERA (SLERA), and Detailed Level ERA (DLERA). Although data gaps remain, a great deal of progress has been made in the last three years, forming the basis for substantial improvements to ERA for metals.

“…The microcosms were placed on the ground over the natural vegetation and 10 mm mesh stainless steel netting was securely fitted over the top of the microcosm, avoiding the escape of the snails and predation. Therefore, the snails were able to feed on soil, litter and vegetation and were exposed via dermal, respiratory and digestive routes (Coeurdassier et al 2002;Fritsch et al 2008;Gimbert et al 2008b;Scheifler et al 2006). Microcosms were placed side by side (less than 1 meter apart) and animals of each group (C. aspersus ME or BE and C. nemoralis ME or BE) were randomly assigned to microcosms.…”

“…Snail faeces also clearly confirmed that the snails feed on the vegetation in the microcosms (personal observation). Snails can be exposed to pollutants via several routes: oral, dermal and respiratory (Coeurdassier et al 2002;Fritsch et al 2008;Gomot-de Vaufleury and Pihan 2000;Regoli et al 2006;Scheifler et al 2006). Concerning oral exposure, they can be exposed via trophic pathway, by eating soil, litter and vegetation.…”

Investigations of responses to metal pollution in land snail populations (Cantareus aspersus and Cepaea nemoralis) from a smelter-impacted area

A cross-transplantation field experiment was performed to investigate about possible adaptation/acclimatization to metal pollution in common garden snail Cantareus aspersus (ex-Helix aspersa) and brown-lipped grove snail Cepaea nemoralis populations. Adults were collected from an area surrounding a former smelter (ME), highly polluted by trace metals (TMs) for decades, and from an unpolluted site (BE). Subadults of first generation (F1) were exposed in microcosms in a 28-day kinetic study. Four exposure sites were chosen around the smelter along a soil pollution gradient (vegetation and soil otherwise comparable). Bioaccumulation in snail soft tissues globally increased with soil contamination, with Cd, Pb and Zn concentrations reaching 271, 187, 5527 μg g(-1), respectively. Accumulation kinetic patterns were similar between snail species but C. nemoralis showed greater TM levels than C. aspersus. Some inter-population differences were revealed in TM accumulation (bioaccumulation factors, accumulation kinetics) but did not suggest consistent adaptive responses. We did not detect negative effects of TM exposure on snail condition (body weight, shell size, shell weight). ME C. aspersus snails produced heavier shells than BE snails under exposure to TMs at the highest level, suggesting an adaptive response. The protocol used in this study, however, did not allow unambiguously distinguishing whether this response was due to genetic adaptation or to maternal effects. Abnormal but reversible shell development of adult ME C. nemoralis suggested physiological acclimatization. Differences in responses to TMs between populations are observed for conchological parameters, not for bioaccumulation, with different strategies according to the species (acclimatization or adaptation/maternal effects).
