NEET BIOLOGY

Detailed explanation-1: -Mounting evidence suggests that air pollution contributes to the large global burden of respiratory and allergic diseases including asthma, chronic obstructive pulmonary disease, pneumonia and possibly tuberculosis.

Detailed explanation-2: -Pneumonia is undoubtedly a risky respiratory health infection which can become a big problem when air pollution levels flare up. Be it indoors or outdoors, scientists have said that during pollution times, the risk of pneumonia and other severe respiratory problems get doubled, and also increase the risk of mortality.

Detailed explanation-3: -Research shows that air pollution can worsen asthma symptoms. A study of young campers with moderate to severe asthma showed they were 40 percent more likely to have acute asthma episodes on high pollution summer days than on days with average pollution levels.

Detailed explanation-4: -Air pollution is the cause and aggravating factor of many respiratory diseases like chronic obstructive pulmonary disease (COPD) (11, 12), asthma (12, 13), and lung cancer (14, 15).

Detailed explanation-5: -Pneumonia mortality has been associated with long-term exposure to ambient air pollutants, including particulate matter, sulfur dioxide, and NO2 (32, 33).
