“…However, several species are sensitive to toxicants; thus, various algae species are widely recommended for ecotoxicological assays to evaluate the toxicity of water contaminants or as bioindicators for water pollution [ 26 , 27 , 28 , 29 , 30 ]. Microalgae can be an effective tool during the removal of nutrients, heavy metals, and other pollutants from natural waterbodies and wastewaters [ 31 , 32 , 33 , 34 , 35 ].
