Short-term changes in Ca, Pb, Zn and Cd concentrations of the garden snail Helix aspersa Müller from a central London car park

Comparison of the Bioaccumulation Capacities of Copper and Zinc in Two Snail Subspecies (Helix)

“…More particularly, this work provides the basis of research complementary to that of authors who used wild snails to study metal biodisposability in order to evaluate ecological risks in the environment (Beeby, 1985;Beeby and Eaves, 1983;Richmond and Beeby, 1992;Dallinger and Berger, 1992;Rabitsch, 1996).…”

Transfer of Cadmium from Plant Leaves and Vegetable Flour to the Snail Helix aspersa: Bioaccumulation and Effects

“…Martin and Coughtrey (1982) reported BAFs for Cd in terrestrial snails ranging from 1.37 to 7.37 (calculated with the Cd concentration of the litter which was considered the food source). In their study of the metal contamination of a car park in central London, Beeby and Eaves (1983) reported Cd bioaccumulation in soft tissues of 18.0 g)g\. The Cd concentrations measured in dandelion leaves, one of the species of their diet, was about 6 g)g\.…”

“…The main di!erences between the latter and the present study lie in the age of the snails and their diet. Since Beeby and Eaves (1983) demonstrated that Cd concentrations in H. aspersa snails of di!erent age classes do not di!er signi"cantly, the di!erences in Cd accumulation may be attributed to a di!erence in bioavailability of Cd in the various diets. These possible di!erences in Cd bioavailability in the diets used in ecotoxicity tests should be considered when studies are compared, and extrapolation from such tests for a priori risk assessment should be handled with care.…”

A New Approach for Understanding Lead Transfer in Agricultural Soil

“…A high percentage of ecosystems consist of arable land which is treated with agrochemical products forming the upper soil layers. Large quantities of chemical elements infiltrate the waters running off the cultivated soils thereby entering the animal and human food chain (Hopkin 1989;Beeby and Eaves 1983;Alexander 2000;Pedersen et al 2000;Notten et al 2005).…”
