Assessment of contamination by heavy metals (lead, cadmium and zinc) of a teleost the spotted weever (Trachinus araneus Cuvier, 1829) caught in the Bay of Oran
Abstract
Our study focused on the evaluation of the three trace elements: lead, cadmium and zinc, a common bony fish in the western Mediterranean coast of Algeria, Spotted weever (Trachinus araneus, Cuvier, 1829). Sampling took place over a period of three months from February to April, 2013, two bodies were considered representative for the edible part man and gills that represent the filter unit muscle. The concentrations of the metal elements were determined by Atomic Absorption Spectrophotometry The flame , according to three parameters (gender, height and month) and levels of metal accumulation were determined. In this study, the results reveal that the Spotted weever (T. araneus) bioaccumulate three xenobiotics sought; the higher levels are those of zinc, lead to higher concentrations in the lower and lower concentrations are those of cadmium. The results were statistically processed demonstrated no significant difference between the levels of heavy metals in both sexes in muscle tissue against significant values are noted in the gill tissue. The study reveals that the accumulation of pollutants is higher in females than in males. Similarly, it is clear the chemical pressure is marked in younger individuals. Levels of concentrations of metallic elements reflect a certain pollution of the study area (Bay of Oran). In this study, trace metals recorded in the flesh of the living spider does not exceed the limit of the Maximum Allowable Dose (D.MA), but can lead to serious dysfunction in these fish.
