This document discusses different types of air pollution including outdoor, indoor, and acid rain. It notes that air pollution is dangerous because we cannot control the air we breathe. Outdoor air pollution comes from sources like vehicle emissions, industry, and burning of solid fuels. Indoor air pollution from burning solid fuels for cooking and heating is a major health risk, particularly in poor households. Acid rain has adverse impacts on forests, waters, soils and structures when acids fall to the ground from the atmosphere in wet or dry forms. The major causes of air pollution are burning of fossil fuels, industrial emissions, indoor fuel burning, wildfires, microbial decay, transportation, burning of garbage waste, and construction activities.

3. Air pollution is the most dangerous form of
pollution. The cause is that we cannot control the
air that we inhale. Air pollution can be defined as
the presence of gasses such as oxides of carbon,
sulphur and nitrogen in the air.

5. Outdoor air pollution
Outdoor air is often referred to as ambient air. The common sources of outdoor
air pollution are emissions caused by combustion processes from motor vehicles,
solid fuel burning and industry. Other pollution sources include smoke from
bushfires, windblown dust, and biogenic emissions from vegetation (pollen and
mould spores)

6. Indoor Air Pollution
Indoor air pollution is caused by burning solid fuel sources – such as firewood,
crop waste, and dung – for cooking and heating.
The burning of such fuels, particularly in poor households, results in air
pollution that leads to respiratory diseases which can result in premature death.
The WHO calls indoor air pollution “the world’s largest single environmental
health risk.

7. Acid Rain
Acid rain, or acid deposition, is a broad term that includes any form of
precipitation with acidic components, such as sulfuric or nitric acid that fall to the
ground from the atmosphere in wet or dry forms. This can include rain, snow,
fog, hail or even dust that is acidic.

8. Acid rain has been shown to have adverse impacts on
forests, freshwaters, and soils, killing microbes, insects
and aquatic life-forms, causing paint to peel, corrosion of
steel structures such as bridges, and weathering of stone
buildings and statues as well as having impacts on human
health.
