what are the resons responsible air pollution

Air pollution is mainly caused by burning fossil fuels, vehicle exhaust, industrial emissions, household cooking and heating, and forest fires. It also comes from smaller sources like farming, waste burning, solvent use, and dust or particles from brakes and tires.

Main causes

• Vehicle exhaust from cars, buses, trucks, and motorcycles.

• Power plants and factories that burn coal, oil, or gas.

• Household smoke from cooking and heating with wood, coal, kerosene, or other polluting fuels.

• Wildfires and forest fires, which release large amounts of smoke and fine particles.

• Agriculture and waste burning, which can release gases and particles into the air.

• Chemicals from paints, fuels, cleaning products, and industrial processes.

What the pollution contains

Common air pollutants include particulate matter, nitrogen dioxide, sulfur dioxide, carbon monoxide, ozone, and volatile organic compounds. Fine particles are especially harmful because they can go deep into the lungs.

Why it gets worse

Weather can trap pollution near the ground, especially when winds are weak and the air is stable. Sunlight can also react with pollutants from traffic and industry to form ozone and smog.

Simple example

A busy city with heavy traffic, nearby factories, and lots of diesel vehicles can have high pollution even if there is no visible smoke, because many pollutants are tiny and spread through the air.
