Ubiquitous distribution, fast growth rate and manifold relevance has credited algae a potential bioresource in current state of affairs of environmental degradation. In the present study, green alga Chlorococcum sp. has been collected from waste water, isolated and cultured to assess their accumulation and toxicity responses at different As(III) concentration. Results revealed that Chlorococcum sp. treated with 10 µM As(III) showed a minimal reduction (21%) in chlorophyll concentration with high proline and carotenoids content indicating its adaptive tolerance potential against As(III). The EC₅₀ of As(III) for inhibiting growth of the microalgae after 10 days of experiment was 9.4 µM. Further, Chlorococcum sp. accumulated 239.09 µg g^− 1 dw As at the concentration of 10 µM of As(III) after 10 days of treatment. Concentration dependent accumulation pattern and antioxidant responses in Chlorococcum sp. could be a used as a potential bioindicator and bioremediator of As from waste water.

无处不在的分布、快速的生长速度和多方面的相关性使藻类成为当前环境退化状况下的潜在生物资源。在本研究中，绿藻Chlorococcum sp。已从废水中收集、分离和培养，以评估它们在不同 As(III) 浓度下的积累和毒性反应。结果显示，绿球藻。用 10 µM As(III) 处理后，叶绿素浓度降低（21%），脯氨酸和类胡萝卜素含量高，表明其对 As(III) 的适应性耐受潜力。实验10天后抑制微藻生长的As(III)的EC _{50为9.4 µM。}此外，绿球藻属。累积 239.09 µg g−处理 10 天后，浓度为 10 µM As(III) 的^{1 dw As。}Chlorococcum sp的浓度依赖性积累模式和抗氧化反应。可用作废水中砷的潜在生物指示剂和生物修复剂。
