A
variety of air pollutants have known or suspected harmful effects on human
health and the environment. The pollutants are principally the products of
combustion from space heating, power generation or from motor vehicle traffic.
Pollutants from these sources may not only prove a problem in the immediate vicinity
of these sources but can travel long distances.
Health Effects
Generally
if you are young and in a good state of health, moderate air pollution levels
are unlikely to have any serious short term effects. However, elevated levels
and/or long term exposure to air pollution can lead to more serious symptoms
and conditions affecting human health.
This
mainly affects the respiratory and inflammatory systems, but can also lead to
more serious conditions such as heart disease and cancer. People with lung or
heart conditions may be more susceptible to the effects of air pollution.

Environment
Effects
Air
pollution causes damage to plants and animals, affecting biodiversity and crop
yields.
Acid
rain is precipitation containing harmful amounts of nitric and sulfuric acids.
These acids are formed primarily by nitrogen oxides and sulfur oxides released
into the atmosphere when fossil fuels are burned.
In
the environment, acid rain damages trees and causes soils and water bodies to
acidify, making the water unsuitable for some fish and other wildlife. It also
speeds the decay of buildings, statues, and sculptures that are part of our
national heritage, ponds, rivers, and soils, leading to damaged wildlife and
forests.
Toxic
pollutants in the air, or deposited on soils or surface waters, can impact
wildlife in a number of ways. Like humans, animals can experience health
problems if they are exposed to sufficient concentrations of air toxics over
time.
