Biodiversity plays an essential role in sustaining life on Earth and contributing to human well-being, but thanks to industrial and technological progress it has been slowly destroyed, leading in turn to the gradual extinction of species. In Algeria, the malacofauna is largely unexploited, which is why we have carried out a qualitative inventory of terrestrial gastropods in the two regions of north-east Algeria, in order to contribute to the knowledge of the biodiversity of terrestrial gastropods in Algeria. Sampling was carried out on spontaneously vegetated plots in these two regions at 12 different sites. The results enabled us to identify 16 species of terrestrial snails belonging to 6 different families. Several pollutants are accumulated in the various ecosystem compartments. Trace metals (TMEs) are among the most dangerous pollutants. This study was carried out to assess the toxic effects of copper (Cu) on individuals from a population of Eobania canstantina via ex situ ecotoxicity tests.
