Аннотация:Heavy metals uptake by 4 brown seaweeds and 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 had been shown. The statistical analysis (ANOVA) was used to demonstrate taxonomic and ecological differences of metals distribution in biochemical pools of macroalgal thalluses.
