Eco-friendly approach for tannery effluent treatment and CO2 sequestration using unicellular green oleaginous microalga Tetradesmus obliquus TS03

Overview of treatment methods of tannery wastewater

“…Studies and research on the carcinogenicity of several chromium species in animals have typically indicated that CaCrO4, particularly a water-insoluble species, is the primary cause of respiratory cancer [40][41]. In mice, investigations have shown that chromium picolinate is harmful in terms of renal impairment, liver failure, anaemia, skin blisters and pustules, tissue oedema, hemolysis, perceptual, impaired cognitive, neuronal cell damage, and motor activities [42,43].…”

“…Numerous additional health consequences of Cr (VI) are also possible. When inhaled at higher-thannormal levels, certain types of Cr (VI) can induce ulcers, holes in the nasal septum, nosebleeds, sneezing, itching, and runny noses [43][44]. At the point of contact, short-term high-level inhalational exposure may result in adverse side effects such as nasal septal perforations, ulcers, and mucosal irritation [45].…”

“…When maize plants were exposed to Cr, the concentrations of chlorophyll a and b, soluble protein, and grain yield declined dramatically (VI)[39].Studies and research on the carcinogenicity of several chromium species in animals have typically indicated that CaCrO4, particularly a water-insoluble species, is the primary cause of respiratory cancer[40- 41].
