摘要: The influence of light intensity on chromium uptake was studied in two strains the freshwater unicellular alga Scenedesmus acutus (Chlorophyceae) having different sensitivity to Cr poisoning and intensity. were subjected treatments at 3000 80 lux. toxicity assessed by algal growth rate, recovery test, methylene blue staining, determination photosynthetic activity. After 2 4 days treatment, bioaccumulated chromium, cell dry mass, protein carbohydrate contents also assessed. When algae treated lux, bioaccumulation patterns obtained when content related number, or content. A direct relationship between mortality observed only amount In both slower subdued light, suggesting that it is linked energy-dependent processes. difference evident light.
