“…Ni(II) is an abundant metal, which can find its way into the human body through water. It diffuses and accumulates in human organs and causes problems like neurotoxicity, hepatotoxicity, nephrotoxicity, gene toxicity, reproductive toxicity, and diseases, namely, respiratory cancer, cardiovascular and kidney illness [5,6]. Similar to Ni(II), a high concentration of Co(II) in water also has impact on human health and causes low blood pressure, visual and hearing problems, respiratory illness, cardiac problems, and even human decease [7,8].…”
