What health effects are associated with arsenic exposure?

Arsenic exposure is well-documented to have significant health effects, primarily related to skin damage and an increased risk of cancer. Chronic exposure to arsenic, whether through contaminated drinking water, food, or other environmental sources, can lead to various dermatological conditions, including skin lesions, hyperkeratosis, and pigmentation changes. Furthermore, arsenic is classified as a human carcinogen, particularly linked to skin cancers as well as other types such as bladder and lung cancers.

The connection between arsenic and these adverse health outcomes underlines the importance of mitigating exposure to this toxic element. While the other options imply beneficial health effects, arsenic exposure is primarily seen as harmful, further emphasizing the validity of the choice that identifies skin damage and cancer risk as the primary health impacts.
