In this study we were interested in the evaluation of toxicity sub-chronicle of the metal dust collected on the level of the iron and steel complex of EL-Hadjar(Eastern Algeria) on accumulating organizations bio and bio indicator of pollution Helix aspersa. The first results on the metabolic level show that metal dust causes a significant increase in proteins with a significant reduction in the Carbohydrates and lipids on the level of the two studied bodies (digestive Gland and the kidney). With regard to the bio markers we highlighted a reduction in the acetyl cholinesterase (AChE) activity at the level of the head. In addition, the exposure of Helix aspersato metal dust induced a lipidic peroxidation with release of malondialdehyde (MDA) to the level of the studied bodies.
