Air Pollution

Air pollution is the introduction of the mixture of unnecessary dust or gaese on the environment which is also cause the particulate matter,biological materials, or toxic chemicals that cause harm or discomfort to humans or other living organisms, or damages the surroundings around us into ,

The atmosphere is a complex dynamic natural gaseous system that is essential to support life on Earth. Due to air pollution it has treated human health as well as to the depletion of the stratospheric ozone layer. Pollutants can be in the form of solid particles, liquid droplets, or gases which is made be natural or man-made.
4%of death in United State of America is caused by the air pollution . Sulphur oxides,nitrogen dioxide,nitroge oxide, carbon monoxide.carbon dioxide are the toxic gases produced by the air pollution which are very dangerous to living creature
Sources of air pollution refer to the various locations, activities or factors which are responsible for the releasing of pollutants in the atmosphere. These sources can be classified into two major categories which are:
Anthropogenic sources (human activity) mostly related to burning different kinds of FUEL and "Stationary Sources" include smoke stacks POWER PLANT , factories and waste materials, as well as furnaces and other types of fuel-burning heating devices
"Motor vehicles, marine vessels, aircraft and the effect of sound etc which makes loud and unnecessary sounds which directly effect to living creatures. Dust and chemicals practices in agriculture and forestry management.Controlling in burning is a technique sometimes used in forest management, farming, prairie restoration or greenhouse gas abatement. Controlled burning stimulates the germination of some desirable forest trees, thus renewing the forest.
Use of hair spray,perfumes also create air pollution as well as human mind.
Smoke and dust from natural sources, usually large areas of land with little or no vegetation.

pollution

The term pollution has become a greatest problem of today.It is the introduction of contaminants into an environment that causes instability, disorder, harm or discomfort to the nature and ecosystem i.e. physical systems or living organisms.Pollution can take the form of natural hazardous ,energy and chemical substance, such as noise, heat, or light. Pollutants, the elements of pollution, can be foreign substances or energies, or naturally occurring; when naturally occurring, they are considered contaminants when they exceed natural levels. Pollution is often classed as point and non point solution . Pollution has become a huge question among us.It is very unwanted and unnecessary though it is occuring.Lack of education doesn,t happen this,it is created due to the lack of consciousness.So to save environment we have to stop pollution which we are creating by our daily lives.
