Are there any countries that have low levels of arsenic?

Unlike most countries in the region, India and Bangladesh have very deep aquifers that typically have low levels of arsenic. In Bangladesh, one of the poorest and most densely populated countries in the world, concerns about arsenic-contaminated rice crops have led farmers to look for safer sources of water deep underground.

Where was arsenic first found in the world?

Arsenic poisoning was first identified in the early 1980s in West Bengal, India, where health officials linked an outbreak of skin lesions to groundwater pumped from shallow wells. Today, WHO estimates that thousands of people from Pakistan to Vietnam die of cancer each year from long-term arsenic exposure.
