EVALUATION OF TOXICITY AND HISTOPATHOLOGY IN THE LAND SNAIL HELIX VERMICULATA EXPOSED TO INSECTICIDE LAZER

Abstract
Abstract - The intensive and uncontrolled use of pesticides in recent years has led to the emergence of multiple ecological, environmental and health problems. Indeed, the presence of these substances even in small quantities in agricultural products and water, can pose possible health risks. Our study aims to experimentally investigate the toxicity of a widely used insecticide, "Lazer" on snails, Eobenia vermiculata. The results obtained show initially that exposure to Lazer led to a decrease in body mass, a disruption of the biochemical metabolism marked primarily by a decrease in carbohydrates and total lipids and a significant increase in proteins at the level of the hepatopancreas. The histological sections show that there is tissue alteration in the tissue of the hepatopancreas of snails treated with the two doses of Lazer insecticide. In addition, there are disorders in the level of nucleic acids (DNA and RNA) in the digestive gland.
