7. What are the effects of arsenic on human health? 7.1 If a large amount of arsenic is swallowed by humans, in a form that is        readily absorbed, it can cause rapid        poisoning and death. The gut, the heart and the nervous system are        affected. Those who survive acute poisoning may develop pigment spots in the skin and        damage to red blood cells, bone        marrow (where blood cells are made), liver, nerves and brain. Long-term exposure to high levels of arsenic in        drinking water can cause thickening and pigment spots in the skin, and cancer of the skin, lungs, bladder        or kidney. Exposure in the workplace – mainly via the air breathed in –        can cause lung cancer.
