Course Outline
Air and Noise Pollution Engineering 2-3-3 W ENE- 539Chapter 1
Introduction to Air Pollution: Composition and properties of
atmosphere and pure air, Air pollution- definition and historical
background, unit and measurements, Different types of sources and
pollutant and their classification, Limit and standards.
Chapter 2 Effects of Air Pollution: Effect of dust, SPM, RPM,
COx, NOx, SOx, Hydrocarbon etc. on human health, plants, animals
and properties. Global Implications: Acid rain, green house effect,
heat island, ozone depletion, fog etc.
Indoor Air pollution: Sources, impact and control
measurement.Ambient & stack monitoring and laboratory
measurement: of Dust, SPM, RPM, COx, NOx, SOx, and
Hydrocarbons.
Chapter 3 Essential meteorology related to pollutant dispersion,
wind rose, lapse rate & turbulence, wind shear, moisture
humidity etc.
Air dispersion model: Eddy diffusion model, normal distribution
model for point, line, area and volume sources, Plume and puff
model, calculation of GLC & stack height. Development of air
pollutant monitoring network.
Chapter 4 Air pollution control system for stationary and mobile
sources. Principal of Air Pollution Control: self-purification,
dilution, process modification etc. Working principal of different
type of AP control instruments e.g. scrubber, collector, filter,
ESP, catalytic converter etc.Chapter 5 Noise pollution, Concept of
sound propagation, Basic physics and wave theory (octave and other
spectra) of sound, measurement of sound r m s and sound pressure
levels, Weighting networks A, B, C types, Effect of sound, Noise
rating system, limit and standards for different zone and sources,
Noise influence and mitigation for houses, transport, community,
industrial and commercial sector.
Chapter 6 Soil pollution, composition, pollution sources,
prevention, soil conditioning & Treatment
Discuss briefly about the ambient air indicating therein the
composition of clean air
What are the broad air pollution categories
Define particulate matter, aerosol, fume, mist & soot
