Which condition is NOT a consequence of air pollution?

Air pollution is known to have significant health impacts, particularly on respiratory health. Conditions such as asthma aggravation, chronic bronchitis, and emphysema are direct consequences of exposure to polluted air. For example, asthma can be exacerbated by pollutants like ozone and particulate matter, as these substances irritate the airways. Chronic bronchitis, characterized by long-term inflammation of the bronchi, is often linked to long-term exposure to harmful air pollutants, leading to persistent cough and mucus production. Emphysema, a form of chronic obstructive pulmonary disease (COPD), involves damage to the air sacs in the lungs due to pollutants, ultimately impacting breathing capacity.

In contrast, diabetes is primarily influenced by factors such as genetics, diet, and physical activity rather than air quality. While some studies suggest a potential link between air pollution and the onset of diabetes, it is not recognized as a direct consequence of air pollution in the same way as the respiratory conditions mentioned. Therefore, diabetes stands out as the condition that is generally not categorized as a direct consequence of air pollution.
