Arsenic is a highly toxic element derived from both natural and human sources, the accumulation of which can trigger cancer and skin diseases in humans. A key human health concern is the contamination of drinking water and soils with arsenic, a phenomenon which is particularly prevalent in South and South-East Asia where rice is grown in contaminated water and soils. Rice plants are particularly good at absorbing arsenic, and the chemical accumulates heavily in the rice grains, subsequently transferring to the food chain.
