What is the primary source of arsenic poisoning?

The primary source of arsenic poisoning is associated with contaminated water supplies. Arsenic, a naturally occurring element found in the earth's crust, can leach into groundwater, particularly in areas with high geological arsenic content or where mining activities have occurred. When individuals consume contaminated water, they are at risk of arsenic exposure, which can lead to acute and chronic health effects.

Herbicides and pesticides may contain varying chemicals, but arsenic is not a common ingredient in many of them today, especially given regulations that have phased out their use. While they can pose health risks, they are not the leading cause of arsenic poisoning compared to the risks associated with drinking contaminated water. This underscores the importance of water quality testing, especially in rural areas or regions with known arsenic contamination, to prevent health issues related to arsenic exposure.
