“…Molluscs are abundant and widely distributed, and their use as biomonitors has been on the rise (Lagadic and Caquet, 1998), especially with reports of specific syndromes in response to specific chemicals such as the imposex phenomenon (imposition of male characteristics) observed in response to tributyltin exposure in some susceptible marine snails (reviewed by LeBlanc and Bain, 1997). Recent reports have described snails being used as indicators of metal toxicity (Flessas et al, 2000;Gomot, 1998), pesticides (Legierse et al, 1998), herbicides (Tate et al, 1997;Jumel et al, 2002), industrial waste dump contaminants (Pihan and Vaufleury, 2000), and various other chemicals, including oil and oil dispersants (Gulec et al, 1997).…”

Aquatic and pulmonate snails were evaluated for their suitability as biomonitors of habitat recovery following an experimental oil spill in a freshwater marshland. The mystery snail, Viviparus georgianus, and the mimic pondsnail, Pseudosuccinea columella, were used as sediment quality biomonitors for a controlled oil-spill experiment at a wetland site along the St. Lawrence River (Ste. Croix, Quebec) to assess the impacts of crude oil, rates of natural recovery, and the efficacy of bioremediation treatments to enhance the bacterial degradation of residual oil in the sediments. Sediments from control sites and oiled sites with or without the application of fertilizers as bioremediation strategies, were evaluated both in situ and under controlled laboratory conditions at various time intervals. Snail survival, growth, and histopathological changes were monitored. While V. georgianus proved to be good biomonitors, P. columella appeared unaffected by the treatments. The differing sensitivity may depend on the gastropods' feeding habits. V. georgianus being a detritivore assimilated contaminants from the sediments, while P. columella, being an herbivore, did not directly assimilate contaminants. Nevertheless, snails show potential as important and ideal "tools" for testing environmental conditions because of their abundance, ease of collection, wide distribution, and relatively sedentary nature.

“…Despite being transferred along soil-plant-snail food chains [27], [28], [39], there is no information available concerning the uptake of manganese by land snails via cutaneous contact and/or soil ingestion. This study provides, for the first time, solid evidence for the existence of such a mechanism by demonstrating that the transfer of manganese from soils to terrestrial gastropods occurs independently of food ingestion.…”

Soil Manganese Enrichment from Industrial Inputs: A Gastropod Perspective

et al. 2014

Manganese is one of the most abundant metal in natural environments and serves as an essential microelement for all living systems. However, the enrichment of soil with manganese resulting from industrial inputs may threaten terrestrial ecosystems. Several studies have demonstrated harmful effects of manganese exposure by cutaneous contact and/or by soil ingestion to a wide range of soil invertebrates. The link between soil manganese and land snails has never been made although these invertebrates routinely come in contact with the upper soil horizons through cutaneous contact, egg-laying, and feeding activities in soil. Therefore, we have investigated the direct transfer of manganese from soils to snails and assessed its toxicity at background concentrations in the soil. Juvenile Cantareus aspersus snails were caged under semi-field conditions and exposed first, for a period of 30 days, to a series of soil manganese concentrations, and then, for a second period of 30 days, to soils with higher manganese concentrations. Manganese levels were measured in the snail hepatopancreas, foot, and shell. The snail survival and shell growth were used to assess the lethal and sublethal effects of manganese exposure. The transfer of manganese from soil to snails occurred independently of food ingestion, but had no consistent effect on either the snail survival or shell growth. The hepatopancreas was the best biomarker of manganese exposure, whereas the shell did not serve as a long-term sink for this metal. The kinetics of manganese retention in the hepatopancreas of snails previously exposed to manganese-spiked soils was significantly influenced by a new exposure event. 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.

“…Ecological monitoring uses the response of living organisms to assess the chemical quality of water by examination of pollutant concentrations in the organisms' tissues, where algae, macroinvertebrates and fish are important indicators (Abel, ; Mandaville, and Gadzała‐Kopciuch et al ., ). Several investigators (Laskowski & Hopkin, ; Pihan & de Vaulfleury, ; Swaileh et al ., ; Ibrahim, ; Moolman, Van Vuren & Wepener, ) decided that snails are considered as suitable diagnostic organisms for heavy metal–contaminated sites (examination of pollutant) in tissues, because they are able to accumulate large quantities of metals in their tissues. The intoxication of the snail is a result not only of soil ingestion (Gomot et al ., ) but also of epithelial absorption of the contaminants (Blackmore, ).…”

The aim of this investigation is to study some freshwater snails as bioindicator for heavy metals Cd, Cu and Pb by determining the concentration of these metals in the field water samples and in whole snail tissues. Seven freshwater snails were used in the present study, some of which are considered medically important snails in Egypt, Biomphalaria alexandrina and Bulinus truncatus, the intermediate hosts for schistosomiasis and nontarget snails Bellamya unicolor, Cleopatra bulimoides, Helisoma duryi, Physa acuta and Theodoxus niloticus. Samples of snails were gathered from three Egyptian governorates: Damietta, Giza and Monufia.. The snails were arranged according to their accumulated concentration of the above-mentioned microelements in descending order as follows: C. bulimoides > H. duryi > B. truncatus > B. alexandrina >P. acuta > B. unicolor > T. niloticus. It is concluded from the analysis of water and the investigated snails that these snails can accumulate Cu, Pb and Cd with high concentrations in their bodies, so they can be used as bioindicators for heavy metals. RésuméLe but de cette recherche est d'étudier certains escargots d'eau douce en tant que bioindicateurs de métaux lourds tels que Cd, Cu et Pb en déterminant la concentration de ces métaux dans des échantillons d'eau prélevés sur le terrain et dans tous les tissus des mollusques. Nous avons utilisé sept escargots d'eau douce dans cette étude, dons certains sont considérés comme importants pour la médecine égyptienne, Biomphalaria alexandrina et Bulinus truncatus, les hôtes intermédiaires pour la schistosomiase, et des escargots non visés Bellamya unicolor, Cleopatra bulimoides, Helisoma duryi, Physa acuta et Theodoxus niloticus. Des échantillons d'escargots furent prélevés dans trois gouvernorats: Damietta, Giza et Monufia. Il ressort clairement des analyses de l'eau et des escargots sur le terrain que ces derniers peuvent accumuler du Cu> Pb> Cd dans leur corps et peuvent donc servir de bioindicateurs de métaux lourds. Les escargots furent classés en ordre décroissant selon la concentration de l'accumulation de ces microéléments: C. bulimoides > H. duryi > B. truncatus > B. alexandrina > P. acuta > B. unicolor > T. niloticus. On en conclut que ces escargots peuvent accumuler du Cu, du Pb et du Cd à de fortes concentrations et qu'ils peuvent donc servir de bioindicateurs de métaux lourds.
