Abstract

Modern methods are receiving more attention lately for the treatment of heavy metals found in wastewater [1]. Because biological processes have been shown to be sustainable, easy to understand, and green [2]. We have made an effort to disseminate information about various microalgae strains utilised for heavy metal removal and their remediation mechanisms with the aid of this review [3]. Getting rid of heavy metals is accomplished by several external and intracellular pathways in microalgal species [4]. In-depth discussion has been had on heavy metal mechanisms and phytoremediation. It is evident that heavy metal bioremediation is insufficient. is not a cost-effective tactic. As a result, efforts to create integrated remediation systems have increased in an effort to make this procedure more affordable [5]. Likewise green technology. As a result of the talks in this review, it can be said that phytoremediation may significantly contribute to the remediation of heavy metals in a sustainable manner as well as the realisation of bio economic potential [6]. Heavy metals are among the most harmful water contaminants. However, 80% of the wastewater that hasn't been treated gets dumped into the water [7].
