The effect of accumulation of metals on selected physiological biomarkers in Cochlodina (Cochlodina) laminata (Pulmonata:Clausiliidae) inhabiting urban biocenoses / Wpływ akumulacji metali na wybrane biomarkery fizjologiczne Cochlodina (Cochlodina) laminata (Pulmonata:Clausiliidae) zasiedlających urbicenozy

Using the small-sized snail species Cochlodina (Cochlodina) laminata, commonly found throughout Europe, an analysis was made of the accumulation of metals in the soft tissues and shells of these molluscs. Three locations were compared, all near cemeteries in Lublin, which were characterised by varying degrees of human impact. It was determined that this representative of the family Clausiliidae can be included in the set of Pulmonata taxa useful for biomonitoring, alongside Arianta, Cepaea, and Fruticicola. The soft tissues were found to have macro-concentration properties for Zn, Cu, and Cd in relation to the values determined in the soil, while micro-concentration was observed in the case of Fe, Pb, and Cr, both in the soft tissues and in the shells. Phenotypic differences were found in the Enterobacteriaceae bacteria associated with the digestive tract of the snails
