Which environmental factor is a common source of carcinogen exposure?

Air pollution is a common source of carcinogen exposure due to the presence of harmful chemicals and particulates released into the atmosphere from various sources, such as vehicle emissions, industrial processes, and agricultural activities. These pollutants can include substances known to cause cancer, such as benzene, formaldehyde, and polycyclic aromatic hydrocarbons (PAHs).

Inhalation of polluted air can lead to chronic respiratory issues and increase the risk of developing various types of cancer, especially lung cancer. The connection between long-term exposure to air pollution and increased cancer incidence is well-documented, making it a significant public health concern.

While freshwater sources, solar radiation, and deforestation can have environmental and health impacts, they are not as directly linked to carcinogen exposure in the same consistent manner as air pollution. For instance, while solar radiation can lead to skin cancer through UV exposure, it is not classified in the same broad category of environmental carcinogens as air pollutants. Similarly, freshwater sources may contain contaminants, but they are generally less associated with carcinogenic outcomes compared to the proven effects of polluted air. Deforestation can contribute to other issues, such as loss of biodiversity and climate change, but is less directly correlated with the release of carcinogens in
