AIR POLLUTION
One could claim that Air Pollution started when humans
began burning fuels or open-burning. In other words, all man made emissions into the air can be called air pollution, because they alter the chemical composition of the natural atmosphere.
Introduction
Air Pollution is the introduction of particulates or otherharmful materials into Earth’s Atmosphere.
Anthropogenic Sources (Man-Made) Natural Sources
Define of Air Pollution
Construction sites produce a lot of dustConstruction Sites
Releases the dangerous compoundsCarbon Monoxide, Benzene, Lead, Dioxin and other
Open Burning
Carbon monoxide gas from motor vehicle exhaustMotor Vehicle Exhaust
Ash from a volcanic eruptionVolcanic Eruption
Release of smoke, Ash, Dust, Carbon dioxide, Nitrogen oxidesForest Fires by lightning
Windblown dust from areas with little vegetationDesert Area
An air pollutant is a substance in the air that can haveadverse effects on humans and the ecosystem. The substance can be Solid particles, Liquid droplets, or Gases.
Primary Pollutants Secondary Pollutants
Pollutants
Pollutants emitted directly into the air. Primary pollutants are usually produced from a process.
Sulphur oxides (SOx) Carbon monoxide (CO) Nitrogen oxides (NOx) Ammonia (NH3)
Primary Pollutants
A chemical compound with the formula SO2 . Coal and petroleum often contain sulphur compounds, and theircombustion generates sulphur dioxide.
Sulphur oxides (SOx)
Sulphur Dioxide (SO2) released from factoriesSulphur oxides (SOx)
Petroleum combustionSulphur oxides (SOx)
It is a product by incomplete combustion of fuel such as natural gas, coal or wood.
Carbon monoxide (CO)
Natural gas is used for everyday cookingCarbon monoxide (CO)
Vehicular exhaust is a major source of carbon monoxideCarbon monoxide
Nitrogen oxides, particularly nitrogen dioxide, are expelled from high temperature combustion.
