Evaluation du risque de contamination par le cadmium de l’espèce Abramis brama capturée dans le barrage "Béni Haroun"

Abstract

In aquatic ecosystems, metallic contamination has attracted a big attention of scientific community and international environmental protection organizations. Because it is one of the most threatening aspects of pollution in these environments. By its toxic effects, it may generate critical or even dangerous situations.The aim of this study was to assess the risk of cadmium contamination in BeniHaroun dam. For that, we sampled the species fish (Abramis brama) in three different stations during the period March- October. The obtained e results showed high concentrations of cadmium that exceed the international limit values (FAO; OMS; European, Chinese, and English) of cadmium in fish used for human consumption. Human health risk assessment of Cadmium based on the calculation of EDI and TQH showed that the consumption of bream (Abramis brama) farmed in Beni Harounis completely safe for human health.
