AIR POLLUTION AND ITS CONTROL
Group A

Introduction: History of air pollution, air pollution systems, concepts of air quality, air quality
criteria and standards, atmospheric chemistry and philosophy of air
pollution control.
Air Pollution sources: Stationary—industrial, domestic, non-point Mobile: Petrol and diesel-
driven vehicles.
Assessment of air pollution: Preparation of emission inventory, emission factors, pollution
loads.
Effects of air pollution: Human health, vegetation and property.
Air quality surveillance: Design of air quality monitoring network.
Meteorology: Physics of atmosphere—sun atmosphere, heat balance, wind speed, direction,
ventilation, mixing height, stability, class.













Group B

 

Transport and dispersion of pollutants: Turbulence, advection, diffusion equation, Gaussian
model and its variation, plume rise, fate process and migration pathways, dry and wet
deposition.
Engineering control: Setting chambers, inertial devices, bagfihers, dry and wet scrubbers,
mobile source control, two- and three-way catalytic converters.
Source sampling and monitoring: Isokinetic sampling. Air pollution legislations, international
treaties, emission standards. Global and regional air pollution issues.
