Urine arsenic

The total amount of arsenic in adults is 15-20mg, which is mainly distributed in hair, nails, bones and skin. The arsenic that enters the body is first transformed in the blood, and then distributed to the whole body tissues. The arsenic in the body is mainly excreted from the urine. Arsenic poisoning is related to the strong binding of arsenic to sulfhydryl groups in the body, which inactivates a large number of thiol-containing enzymes, thereby hindering intracellular biochemical metabolism and significantly reducing the body's antioxidant capacity.
