Environmental pollution is increasing day by day due to anthropogenic activities and different types of toxic contaminants such as heavy metals, chemicals, dyes, pesticides etc enter the environment from different sources such as municipal, industries and agricultural. Among wastewater treatment techniques, bioremediation is one of promising techniques, which utilize the inherent biological mechanism of plant and microorganism for the remediation of diverse pollutants. Microalgae have been applied to mitigate the toxic and recalcitrant pollutants in the effluents. Microalgae have the capacity to remove different types of contaminants through different methods such as biosorption, bioaccumulation and biodegradation. It has been observed that microalgae can remove the pollutants originated from the domestic effluents, agricultural runoffs, textile, leather, pharmaceutical and electroplating industries etc. Additionally, the microalgae have the ability to mitigate the carbon dioxide in their growth process and utilize the micronutrients in the effluents. This review paper critically analysed the application of microalgae for the remediation of diverse types of pollutants commonly present in the environment through different mechanisms.

由于人为活动，环境污染与日俱增，重金属，化学药品，染料，农药等不同类型的有毒污染物从市政，工业和农业等不同来源进入环境。在废水处理技术中，生物修复是一种很有前途的技术，它利用植物和微生物固有的生物机理来修复各种污染物。微藻已被用于减轻废水中的有毒和难降解的污染物。微藻具有通过不同方法（例如生物吸附，生物积累和生物降解）去除不同类型污染物的能力。据观察，微藻可以去除源自生活污水，农业径流，纺织品，此外，微藻具有在生长过程中减轻二氧化碳排放并利用废水中的微量营养素的能力。这篇评论文章严格分析了微藻在通过不同机制修复环境中常见的各种类型污染物中的应用。
