Pollution of the environment and hydrobionts by heavy metals in region of the archipelago Argentina islands
Description Toxicological investigations in the Argentine Islands Region is detected the raised contents in water, soils and hydrobionts of a series of heavy metals with different toxicity (Ryasintseva and al., 1998, Samyshev, Kopytov, 2007).
During the complex monitoring, founded by us around the Ukrainian Antarctic station, the curious phenomenon is revealed. The established early high contents of heavy metals in water and especially in suspended matter in the Region is obliged to the presence of them in soil of practically all investigated islands of the Archipelago as a result of washing-off. Formation of «bouillon» from the broad spectrum of these natural pollutants is caused by accumulation of them by hydrobionts, especially intensive by macrophytes and zoobenthos of the coastal water area. The revealed phenomenon is interest of subsequent researches of physiological features at the organisms-accumulators of pollutants and mechanisms of their adaptation. Under preliminary data the contents of chlorocarbonic pollutants in soil of the islands is insignificantly small. Author E.Z. Samyshev, Yu.P. Kopytov· JPG file - 2.30 MB - 2 384 x 3 370 pixels
