Air Pollution

Introduction

Air pollution is the introduction of chemicals, particulates, biological materials, or other harmful materials into the Earth's atmosphere, possibly causing disease, death to humans, damage to other living organisms such as food crops, or the natural or built environment.


Causes of Air pollution

Air pollution is caused mainly by Transportation, fuel combustion in stationary sources, burning of fossil fuels like coal, wood, dry grass, and construction activity. Motor vehicles produce high levels of Carbon Monoxide (CO) and Hydrocarbons (HC) and Nitrogen Oxides (NO). Construction activities, bad roads and burning of fossil fuels are responsible for Dust (particulate matter) Pollution. Residential and Commercial activities also contribute to Air Pollution.


Effects of Air Pollution

Some of the effects of Air pollution on Human, Animals and Environment are as:

  • Reduced lung functioning, coughing, asthma attacks, bronchitis.
  • Irritation of eyes, nose, mouth and throat, headaches.
  • Cardiovascular problems.
  • Cancer
  • Acid rain destroys fish life in lakes and streams and kills trees, destroy the leaves of plants, can infiltrate soil by making it unsuitable for purposes of nutrition and habitation.
  • Excessive ultraviolet radiation coming from the sun through the ozone layer in the upper atmosphere which is eroded by some air pollutants may cause skin cancer.
  • Ozone in the lower atmosphere may damage lung tissues of animals and negatively affecting plants photosynthesis rates which will stunt plant growth.
