What is the largest source of arsenic?

The largest source of arsenic exposure for most people is food and drinking water, with natural arsenic from soil and rocks dissolving into groundwater and being absorbed by crops like rice, making it a major dietary concern, while seafood is another significant food source, though usually with less harmful organic forms.

Arsenic naturally occurs in soil, leading to absorption by crops, but rice absorbs it readily, making it a significant source of inorganic arsenic, with infants and young children often most affected.
