Exposure to arsenic within the United States can occur through many routes. It has been used with both criminal and suicidal intent as an agent to poison individuals or groups. [15] Medications used to treat disease, such as the chemotherapeutic agent arsenic trioxide, are iatrogenic sources. Industrial exposure to the waste products of smelting plants is another potential source. Arsenic-containing pesticides are still used in some areas of the country, with its use mostly found in cotton fields. [16]

According to the AAPCC, in 2019, there were 605 single exposures related to arsenic (excluding pesticides) and 16 exposures to arsenic-containing pesticides. [14]
