Abstract
In this experimental study we were interested in the evaluation of impacts
pollution of the grounds of some biotopes of Khenchela by the use of a
bioindicator, Cantareus aspersus, (Mollusca, Gasteropoda), snail very abandant
on the level of four sites study.
The physicochemical analysis of grounds reveals us that we are in the
presence of ground with argilo-muddy texture, slightly basic (pH > 7,5) no saline
(conductivity, 1-0,3 m mohs/cm), who retain little hygroscopic moisture and who
have a rather strong porosity between 10-20% in the four sites of studies.
The proportioning of two biomarqueurs (AChE and GST) reveals that
the sites of Fais and Kais. El-Hamma is the site less polluted.
