Arsenic is a naturally occurring element widely distributed in the earth’s crust. In the environment, arsenic is combined with oxygen, chlorine, and sulfur to form inorganic arsenic compounds. Arsenic in animals and plants combines with carbon and hydrogen to form organic arsenic compounds.
Breathing high levels of inorganic arsenic can give you a sore throat or irritated lungs.
Ingesting very high levels of arsenic can result in death. Exposure to lower levels can cause nausea and vomiting, decreased production of red and white blood cells, abnormal heart rhythm, damage to blood vessels, and a sensation of “pins and needles” in hands and feet.
Ingesting or breathing low levels of inorganic arsenic for a long time can cause a darkening of the skin and the appearance of small “corns” or “warts” on the palms, soles, and torso.
Criminal gangs are increasingly using the internet to market life-threatening counterfeit medicines and some have even turned up in legitimate outlets such as pharmacies, according to a review led by Dr Graham Jackson, editor of IJCP, the International Journal of Clinical Practice, and published in the March edition.
Rice is among the plants that are efficient in taking up arsenic from the soil, environmental chemist Brian Jackson of Dartmouth College in Hanover, N.H., and his co-authors said in Thursday's issue of the journal Environmental Health Perspectives. Long-term exposure to extremely high levels of inorganic arsenic can increase the risk of lung, liver and bladder cancer as well as miscarriage and infertility.

Studies have shown that rice takes up more arsenic from soil than other crops. Now a new study shows that higher arsenic levels are ingested by women who eat as little as half a cup of cooked rice in a day. Currently, there are no limits on the amount of allowable arsenic in rice in the United States. But the Environmental Protection Agency has set arsenic limits in water of 10 parts per billion.
