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.
