This document outlines the syllabus for a course on air and noise pollution control. It covers topics such as the composition of the atmosphere, classification of air pollutants, air pollution chemistry, ambient air quality standards, and methods for controlling air and noise pollution. Specific control methods discussed include particulate control technologies like cyclones and fabric filters, gaseous pollutant controls like absorption and combustion, automotive emission controls, and noise pollution fundamentals and control strategies.

KCE 057

2. SYLLABUS
Unit 1
• Air pollution: composition and structure of
atmosphere, global implications of air
pollution, classification of air pollutants:
particulates, hydrocarbon, carbon monoxide,
oxides of sulphur, oxides of nitrogen and
photochemical oxidants. Indoor air pollution.
Effects of air pollutants on humans, animals,
property and plants.

3. • Air pollution chemistry, meteorological
aspects of air pollution dispersion;
temperature lapse rate and stability, wind
velocity and turbulence, plume behaviour,
dispersion of air pollutants, the Gaussian
Plume Model, stack height and dispersion.
UNIT-2

4. • Ambient air quality and standards, air
sampling and measurements. Control of
particulate air pollutants using gravitational
settling chambers, cyclone separators, wet
collectors, fabric filters (Bag-house filter),
electrostatic precipitators (ESP).
Unit 3

5. • Control of gaseous contaminants: Absorption,
Adsorption, Condensation and Combustion,
Control of sulphur oxides, nitrogen oxides,
carbon monoxide, and hydrocarbons.

convertor, Euro-I, Euro-II and Euro-III
specifications, Indian specifications.
Unit 4

6. UNIT-5
• Noise pollution: Basics of acoustics and
specification of sound; sound power, sound
intensity and sound pressure levels; plane, point
and line sources, multiple sources; outdoor and
indoor noise propagation; psychoacoustics and
noise criteria, effects of noise on health,
annoyance rating schemes; special noise
environments: Infrasound, ultrasound, impulsive
sound and sonic boom; noise standards and limit
values; noise instrumentation and monitoring
procedure. Noise indices. Noise control methods.

7. UNIT – 1
• Structure and composition of atmosphere-:
Earth's atmosphere is composed of about 78%
nitrogen, 21% oxygen, and 0.93% argon. The
remainder, less than 0.1%, contains such trace
gases as water vapor, carbon dioxide, and ozone.

9. • Definition of Air pollutants: Substances
introduces into the air, natural or manmade, in
• concentrations detrimental to human, plant or
animal life, or to property.
• Major Classification of Air Pollutants:
• 1] Primary – Secondary
• 2] Natural – Manmade
• 3] Criteria Air Pollutants
• 4] Physical - chemical - biologicaL

10. • Primary pollutants and secondary pollutants:
Primary pollutants are substances that are
directly emitted into the atmosphere from
sources. Primary pollutants are those that are
emitted directly from identifiable sources.

11. • Primary Air pollutants:-
• (i) Fine (less than 100μ) and coarse (more than
100μ) suspended particulate matter
• (ii) Oxides of sulfur
• (iii) Oxides of nitrogen
• (iv) Carbon monoxide
• (v) Halogens
• (vi) Organic compounds
• (vii) Radioactive compound

12. • Secondary air pollutants are those that are
produced in the air by the interaction of two or
more primary air pollutant.
• Secondary Air pollutants:-
• (i) Ozone
• (ii) PAN (peroxi aceyl nitrate)
• (iii) Photochemical smog
• (iv) Acid mists

13. • Air pollutants arise from both manmade and
natural processes. The ambient air quality may
be defined by the concentration of a set of
pollutants which may be present in the
ambient air we breathe in.
• These pollutants may be called criteria
pollutants.
