ES 610 AIR POLLUTION                                                                                 (2L+IP) III

Objective
To impart theoretical and practical knowledge about the air pollution and pollutants, their sources and formation in the air, effects on crop plants and control measures,

Theory

UNIT I
An overview of air pollution course; air quality, contamination, pollution, and source of various air pollutants; physical and chemical properties of air pollutants

UNIT II
Classification of  air pollutants (primary/secondary /photochemical air pollutants); Physical monitoring of gaseous pollutants and SPM; chemical synthesis of photochemical smog; dispersion and transport of air pollutants

UNIT III
An introduction to air pollution biology; mode of entrance of pollutants into plans; effect of air pollution on vegetation and animal; factors affecting plant response to air pollutants; mode and mechanism of plant-pollutants interaction; defense mechanism against gaseous pollutants in plants; toxicity/injury/symptoms of air pollutants on plants

UNIT IV
Biological (physiological, biochemical and structural) effects of air pollutants (SO2, HF, PAN &O3) and on vegetation; effect of different air pollutants on crop growth and yield; mode of air pollutants interaction and their individual and combined effects on vegetation; tolerant and susceptible plant species; Heavy metal pollution, their source and sinks, movements, uptake and biological effects on crops; heavy metal tolerance in plants, adaptation of  plant species to heavy metals; phytoremediation of heavy metals.

UNIT V
Volatile organic compounds as an air pollutants; acid rain and its effects on vegetation; vegetation as a biological indicator for air pollution; physical, biological and legal control of air pollution and air pollution law; land use planning for polluted areas.

Practicals
Sampling of gaseous pollutants from atmosphere; Measurement of mass concentration of SPM in the air; Measurement of SO2, NOx and O3  concentration in ambient air; Measuring techniques crop response to gaseous air pollutants; Measurement of chlorophyll and carotenoids in plants; Measurement of protein and carbohydrate in plants; Diagnosis of air pollutants effects on vegetation.
