Air PollutionInstructor zgr ZEYDAN (PhD.)Department of Environmental Engineering

Air PollutionExistence of air pollutants (gases and aerosols) in the atmosphere in a way that air becomes harmful to humans, animals, plants and materials.

2Air Pollutants GasesAerosolsSulfur oxides (SOx)Nitrogen oxides (NOx)Carbon monoxide (CO)Volatile organic compounds VOCsChlorofluorocarbons (CFCs)Ground level ozone (O3)

Pollute less!)Conserve energyBuy green (environmental friendly) productsDrive wisely or use public transportUse clean energy sources renewables are preferable instead of fossil fuels.Good city planningSeparate residential and industrial zonesReduce industrial emissionsWaste gas cleaning devices

Environmental Engineers' RoleEnvironmental Engineers study air pollution in several ways:Measure current air qualityDesign air pollution control equipmentsPrepare emission inventoriesMake air pollution modelingSuggest clean air plans
