Snails from a contaminated urban car park were fed an experimental diet for 64 days. One group received a high Pb diet for the duration, and another group were removed from the high Pb diet after two days. Shells were analyzed at various intervals to measure Pb uptake and loss. Regression analysis of twenty-eight shells for each treatment suggests that the weight of Pb in the shell increased linearly with time, but loss from the shell was correlated with soft tissue Pb levels. The shells of… 


Abstract Mercury concentration in the land snail Eobania vermiculata, in plants, soil and air has been carried out in an area affected by a chlor‐alkali complex to evaluate the bioaccumulation

Snail (Helix aspersa) exposure history and possible adaptation to lead as reflected in shell composition

Observations suggest that Pb sequestration in shell has been enhanced in H. aspersa populations with long and intense exposure to Pb.

Soil Manganese Enrichment from Industrial Inputs: A Gastropod Perspective

The results of this study reveal the importance of land snails for manganese cycling in terrestrial biotopes and suggest that the direct transfer from soils to snails should be considered when precisely assessing the impact of anthropogenic Mn releases on soil ecosystems.

Effect of Zn, Cu, Pb, and Cd on fitness in snails (Helix aspersa).

The calculated scenarios of population dynamics under the stress of chronic pollution with mixtures of the four metals revealed that the delayed reproduction due to estivation of snails may be the main cause of population decline at high metal concentrations in food.

Uptake and Fate of Lead in the Common Asteroid Asterias Rubens (Echinodermata)

The central digestive tract and the skeleton are proposed as complementary temporal bioindicators of Pb contamination and suggested that Pb accumulated in the gonads is expulsed later through spawning.


Shells of snails from areas with long histories of Pb contamination were significantly more robust thansnails from other locations, and these do not correlate with genetic traits assessed with allozymes.

Helix aspersa as sentinel of development damage for biomonitoring purpose: A validation study

It is demonstrated that exposure in areas chronically polluted with metals, especially with lead, often causes changes in reproduction, with a variation in the mineral composition in the snail's eggs and also in its development, due to increased energy expenses associated with detoxing and the excretion process.

Bioaccumulation and effects of different‐shaped copper oxide nanoparticles in the deposit‐feeding snail Potamopyrgus antipodarum

The present study stresses the need for both a better understanding of uptake mechanisms and internal distribution pathways of NPs and an assessment of long-term consequences of NP exposure.



Calcium metabolism in two populations of the snailHelix aspersa on a high lead diet

Soft tissue concentrations of lead, calcium, and magnesium were measured in the garden snail, Helix aspersa, over a 64-day dosing regime, finding that concentrations of Pb and Ca can be correlated for the soft tissues of the dosed car park snails.

The Role of Helix aspersa as a Major Herbivore in the Transfer of Lead Through a Polluted Ecosystem

Helix aspersa Muller was studied as a major herbivore in an ecosystem contaminated with lead, and evidence suggests that tissue turnover of the metal increases with consumption and may serve to 'buffer' the supply of Pb to other trophic levels.

Bioaccumulation and Partitioning of Cadmium within the Freshwater Mussel Dreissena polymorpha Pallas

Kinetics of uptake, partitioning and elimination of cadmium were investigated in experimental studies with the freshwater mussel, Dreissena polymorpha, and indicate that the major portion of Cadmium in the soft parts is strongly bound and cannot be eliminated by exchange processes.

Toxic effects of cadmium on the garden snail (Helix aspersa)

Snails, Helix aspersa, were chosen to examine the entrance of cadmium into terrestrial food chains and the effects of accumulation, acute toxicity, and behavioral, reproductive and growth responses with increasing levels of Cadmium are determined.

Cellular responses of molluscan tissues to environmental metals

The composition of intracellular granules from the metal-accumulating cells of the common garden snail (Helix aspersa).

Certain cells in the hepatopancreas of the common garden snail contain intracellular granules that are sites of metal-ion accumulation, and their role in detoxifying heavy-metal ions is discussed.
