Cadmium: Bioaccumulation, Histopathology and Detoxifying Mechanisms in Fish

Metals are being utilized of ways in industries and agriculture; particularly heavy metals such as Mercury, Lead, Arsenic and Cadmium constitute a significant potential threat to human health because they are associated to many adverse effects on health. Due to the increasing pollution, concentrations of various chemical compounds have increased in aquatic environments. Water contaminants have a high potential risk for the health of populations and protection from toxic effects of environmental aquatic pollutants primarily involves considering the mechanism of low level toxicity and likely biological effects in organisms who live in these polluted waters. Fish have the ability to accumulate heavy metal in their tissues. Therefore the intake of fish should be regulated; information regarding the species of fish consumed and its possible levels of content of heavy metals can be of benefit to diminish the hazard to public health. In this mini‐ review we aimed to bring the main work on the harmful effects of cadmium on fish through its accumulation in the tissues, the main histological changes encountered in fish as well as the detoxifying systems against the toxicity of this metal. ey word a K s: Bio ccumulation, Cadmium, Histopathology, Metallothioneins {Citation: Ali Annabi, Khaled Said, Imed Messaoudi.
