Air pollution is caused when air is contaminated with poisonous substances, particulate matter, and droplets of liquid, which damage the health of human beings and other living organisms.
In cities, the air gets polluted by exhaust fumes of vehicles along with the pollutants given off by construction work and industries. In the countryside, dust given off by tractors working on fields, vehicles being driven on gravel or dirt tracks, wood being burnt, and work carried out in rock quarries, are some of the causes of air pollution.
Toxic air pollutants and chemicals, like carbon dioxide, sulfur dioxide, and nitrogen oxides react with water molecules in the atmosphere to form acids. Acid rain contains high levels of hydrogen ions, which can damage trees, crops, vehicles (due to corrosion), pollute water bodies, and harm other aquatic animals.
Therefore, air pollution not only threatens the health of human beings but also disturbs the ecological balance to a great extent. Let's probe further and find out the current scenario.
