Content of Metals Labile Fraction in Surface Waters as the Main Element in Assessing Their Potential Toxicity

Краткое описание

Results of long-term studies on the content of the labile fraction of metals (Fe, Mn, Cu, Zn, Pb, Cr, and Cd) in surface waters of Ukraine by chemoluminescent methods, and also by the method of anode inversion voltamperemetry, are discussed in the paper. It is noted that the data on the concentration of free (hydrated) metal ions as the most toxic their form are essential in assessing their potential toxicity and ecological and toxicological situation in water bodies. It has been found that the contribution of the labile fraction of metals to the total content of their dissolved forms is mainly insignificant, with the exception of manganese. Seasonal dynamics of the concentration of free metal ions were investigated in the studied water bodies. A potential toxicity of metals in the aquatic environment was assessed taking into account the content of their labile fraction.
