Arsenic

Arsenic is a heavy metal that can cause poisoning when it enters the body through food, accidental ingestion, working in the pesticide industry, when pesticides contaminate drinking water, or with the intent of suicide. Arsenic can be found not only in products of the pesticide industry but also in paints and wood preservatives. The concentration of arsenic in the blood is increased only for a few days after it enters the body. Arsenic poisoning leads to hemolytic anemia, hematuria, hemoglobinuria, and acute renal failure.
