Bioavailable heavy metals have been extensively studied in recent years because of their toxicity to natural ecosystems. Even though there is a large number of studies, relatively little is known about the biologically available metal fraction. The current study analyses seasonal concentrations of heavy metals associated with reactive fractions (solvable in HCl) in the soil of three areas on West Jiu river. Concentrations of heavy metals identified in indigenous ichthyofauna (Salmo trutta fario) collected from each habitat area were also measured and compared with the content of metals in different soil fractions. To quantify the process of heavy metals absorption, not eliminated or consumed by catabolism and excretion, samples were prepared in order to be analysed. Measurements were performed both by inductively coupled plasma with optical emission spectrometry and by X-ray fluorescence spectrometry.
The development of bioaccumulation mechanisms has been studied by identifying the key elements thus observing the correlations between water and land adjacent to watercourses. The results consist of identifying and describing the two mechanisms of heavy metals accumulation in both tissues and aquatic environment and soils. |
