NEET BIOLOGY

Detailed explanation-1: -Ozone pollution, the result of hydrocarbons and nitrogen oxide emissions from motor vehicles or other sources, mixed in the presence of sunlight, causes increased wheezing, coughing, and chest tightness, especially among susceptible children who play outdoors in polluted environments.

Detailed explanation-2: -Ozone high in the Earth’s atmosphere protects us from the sun’s harmful radiation. But at ground level, ozone is an air pollutant that harms people and plants.

Detailed explanation-3: -Hence most of the air pollution also occurs in these two layers of the atmosphere. Most of the pollution that causes us so many problems transpires in the troposphere. This is what we call atmospheric pollution or tropospheric pollution.

Detailed explanation-4: -When ozone forms air pollution, it’s also called smog. Some air pollutants are poisonous. Inhaling them can increase the chance you’ll have health problems. People with heart or lung disease, older adults and children are at greater risk from air pollution.

Detailed explanation-5: -Pollution enters the Earth’s atmosphere in many different ways. Most air pollution is created by people, taking the form of emissions from factories, cars, planes, or aerosol cans. Second-hand cigarette smoke is also considered air pollution. These man-made sources of pollution are called anthropogenic sources.
