Air pollutionAir is an important natural resource providing the basis of life on earth.
Pollution had been known to exist for centuries, but it became an issue of serious concern only in the last 200 years or so, mostly due to the industrial revolution.
Atmospheric pollution occurs because the release of air pollutants takes place at a rate much faster than they can be accommodated by the environment and removed from the atmosphere without causing serious harm.
Air pollution is a release into the atmosphere of any substances, e.g. Chemicals or airborne particles, which are harmful both to the human and animal health as well as the health of wider environment.
IndustriesAir pollution is defined as the addition of various
hazardous chemicals, particulate matter, toxic substances and biological organisms into the Earth's atmosphere.
Industries can discharge contaminants into the air.
Approximately 11% of public complaints about air quality in the region are about odour or dust from industry.

industries. Pollution due to atomic units.
