Arsenic is a chemical element found in nature, such as in soil, rocks, and water, especially groundwater. It is a substance that can be toxic to the body if taken in large amounts or for too long. There are two main types of arsenic: inorganic arsenic , which is found in groundwater, soil, or dust from factories, is highly toxic and can cause serious illnesses, such as cancer or death; and organic arsenic , which is found in sea fish, shellfish, or shrimp, is less toxic and the body can excrete it in 2-3 days.
