Which is a source of arsenic exposure?

Arsenic exposure mainly comes from ingesting substances that contain it, with drinking water containing arsenic being the most direct and common route. When groundwater or other water sources have dissolved arsenic, drinking or using that water for cooking allows arsenic to enter the body with each use, leading to cumulative exposure over time. The other options—Vitamin C, oxygen, and sunlight—do not carry arsenic in ordinary circumstances, so they do not serve as sources of arsenic exposure.
