Аннотация:Heavy metals accumulation by 4 green macroalgae and the distribution in biochemical pools of their thalluses were studied in short-term experiments (24 h). Utilisation of carbohydrate and protein mechanisms of metals localization by macroalgae under background and experimental (0.3 mg/l) conditions has been shown. The statistical analysis (ANOVA) was used to demonstrate macroalgae the taxonomic and ecological regularities of metals distribution in biochemical pools of thalluses.
