DAMAGE TO THE NERVOUS SYSTEM AND CHANGES IN THE LIVER AS A RESULT OF POISONING BY ARSENIC ENTERING THE BODY

Arsenic is ranked first among toxicants posing a significant potential threat to human health based on known or suspected toxicity. This naturally occurring metalloid is a known poison, a co-carcinogen, and in lower concentrations has been shown to increase susceptibility to cognitive dysfunction. Currently, the permitted concentration of arsenic in water is 10 μg/L (10 ppb). Arsenic (As) is a common environmental contaminant widely distributed around the world. Human exposure to this metalloid comes from well water and contaminated soil, from fish and other sea organisms rich in methylated arsenic species, and from occupational exposure. Research We conducted experiments on 15 white rats weighing 140-260 g, kept in the vivarium under normal conditions at the Scientific Research Center of the Azerbaijan Medical University, and divided them into 3 groups. We determined malondialdehyde (MDA), diene conjugates (DC), which are lipid peroxidation (LPO) products, and catalase, which is an antioxidant product, in blood taken from experimental animals.
