“…Alternatively, according to Laskowski and Hopkin (1996a) the solubility of Pb in the gut of snails may be much lower; hence less will be assimilated by the hepatopancrease. Laskowski and Hopkin (1996b), Gomot (2000) recorded no reduction in growth from Pb even at very high dose (30,000 lg/g). The highest feed utilization was recorded by snails at control site (Table 2), likewise R. sativus contained highest crude protein and least crude fiber (Table 1).…”

We investigated juvenile Achatina achatina snails exposed as sentinels in plastic cages for 12 weeks to compare lead pollution at dump sites of abandoned battery factory (Niger Delta, Nigeria). Results indicated 0.56, 20.37, 200.42 and 1200.30 microg/g soil lead at control, storage, dried effluent and waste dump sites, respectively. There were significant (p < 0.05) depression in snail growth with increasing level of lead pollution. Snails were tolerant of all levels of lead pollution with no mortalities. This novel approach provides a basis for use of snail data in environmental pollution assessment of industrial sites.

“…Repeated measures ANOVA showed a highly significant treatment ×mass change interaction (F 18,162 =3.67, P B0.0001), indicating that Several studies have shown H. aspersa to be relatively tolerant of some metals. For example, Gomot-de Vaufleury (2000) showed no negative growth or survival effect for H. aspersa consuming a diet of 30,000 mg Pb g − 1 . Other metals impacted snails at lower concentrations: Zn decreased snail growth at 6,000 mg g − 1 and Cu at 1,000 mg g − 1 .…”

“…From reports of other metals tested on H. aspersa in the literature (Pb, Cu, Zn, and Cd), only Cd has been reported to show negative effects at lesser concentrations (Laskowski & Hopkin 1996;Gomot-de Vaufleury & Kerhoas 2000;Gomot-de Vaufleury 2000).…”

Nickel defends the South African hyperaccumulator Senecio coronatus (Asteraceae) against Helix aspersa (Mollusca: Pulmonidae)

The elevated Ni concentration of Ni hyperaccumulator plants has been proposed to be an effective chemical defence against herbivores. To test this hypothesis, we fed leaves from hyperaccumulator and non-hyperaccumulator populations of South African Senecio coronatus to a generalist herbivore species, the brown garden snail (Helix aspersa). Snails fed hyperaccumulator leaves experienced significantly greater mortality than those fed non-hyperaccumulator leaves and also contained 10-fold greater concentrations of Ni. A choice experiment showed snails preferred non-hyperaccumulator leaves in two of three trials. Snails fed cornmeal diet amended with Ni had significantly reduced mass for diets containing as little as 140 mg Ni g − 1 , and significantly greater mortality occurred for snails consuming diets containing 830 mg Ni g − 1 and greater. Because hyperaccumulator S. coronatus leaves contained far more Ni (12,100 mg Ni g − 1 ) than the toxic threshold shown in the diet experiment, we concluded that the Ni concentration of hyperaccumulator leaves was sufficient to cause the elevated mortality of snails fed those leaves. This research adds another example to the growing literature showing the toxicity of hyperaccumulated Ni to generalist folivores.

“…The growth toxicity test of Helix aspersa (Mül-ler) made by Gomot-de Vaufleury (2000) showed that a high content of Cu (above 1 μg/kg), Zn (4 μg/kg) and Cd (0.14 μg/kg) in soil inhibited the growth of the snails, while Pb had no toxic effects. The major route of contamination in terrestrial organisms is pollutant absorption through food (Hopkin 1989).…”

Soil samples and snails -Helix pomatia Linnaeus, 1758 specimens were collected from the region of Małopolska. Research based on soil from this area showed a differentiated degree of environmental contamination, which influenced the composition of elements that build mollusc shells. Concentrations of Pb, Mn, Cd, Fe, Zn and Cu in the snail shells and soil varied between localities. The highest of these concentrations were found in the soil in the city of Cracow. They were higher than those measured in the regions outside the city, 7 times in the case of Cd, and up to 123 times higher for Cu. Positive association between soil pollution and shell contamination can be observed (r s ≈ 0.9). A high concentration of metals in the environment and their bioavailability causes long-term accumulation of these elements in Helix pomatia shells.
