Question

What are the major sources of air pollution?

Answer 1

Hint: We need to understand air pollution and also the major sources which cause it. The presence of chemicals in the atmosphere that are hazardous to human and other living beings' health or damage the climate or materials is called air pollution. Many pollution-related illnesses, including respiratory infections, heart disease, COPD, stroke, and lung cancer, are all linked to air pollution.

Complete answer:
Air pollution includes gases (such as ammonia, carbon monoxide, sulphur dioxide, nitrous oxides, methane, and chlorofluorocarbons), particles (both organic and inorganic), and living molecules.” Polluted air is defined as air that contains hazardous or unwanted chemicals produced by human or natural processes and whose concentration interferes with human health or is harmful to the environment. A pollutant in the atmosphere is a substance that can harm humans and the environment. The material can be solid particles, liquid droplets, or gases. Pollutants can be both natural and created by humans. Pollutants are classified into two types: main and secondary. Natural processes, such as volcanic ash, produce primary pollutants. Carbon monoxide gas emitted by automobiles and sulphur dioxide emitted by industry are two additional examples. Secondary pollutants are not emitted directly. Rather, they are produced in the atmosphere as a result of the reaction or interaction of primary pollutants. Ground-level ozone is a frequent example of a secondary pollutant.
There are four major categories of sources of air pollution:
Vehicles, buses, aircraft, trucks, and trains are examples of mobile sources.
Power plants, oil refineries, industrial facilities, and factories are examples of stationary sources.
Agricultural regions, cities, and wood-burning stoves are examples of local supplies.
Wind-blown dust, wildfires, and volcanoes are examples of natural sources.

Note:
 It is important to note that air pollution can cause illnesses, allergies, and even death in humans; it can also harm other living species, such as animals and food crops, as well as have an impact on the natural environment (such as climate change, ozone depletion, and habitat destruction) and the built environment (for example, acid rain). Air pollution may be caused by both human activity and natural sources.
