Which option best describes the impact of arsenic on health?

Arsenic is a well-known toxic substance that poses significant health risks, particularly with long-term exposure. The impact on health includes the potential for skin damage, as well as increased risk of various forms of cancer, particularly skin, bladder, and lung cancers. Chronic exposure can occur through contaminated water, food, or air, and it can lead to serious health conditions including arsenicosis, characterized by skin lesions and other systemic effects.

This understanding of arsenic’s effects is supported by extensive research and data indicating that even lower levels of exposure can be harmful over time. Therefore, the assertion that arsenic can cause skin damage and increase cancer risk is accurate and aligns well with the documented effects of this hazardous substance.

The other options do not represent the reality of arsenic's impact on health appropriately. The notion that it has no significant health impacts, enhances physical performance, or is only harmful in very high doses misrepresents the potential dangers associated with arsenic exposure. Public health guidelines frequently emphasize the need to minimize arsenic exposure due to its well-established risks.
