Course

Unit 1

Instrumental methods for analysis of contaminants in air, water and soil – colorimetry, Chromatography, spectroscopy, electrochemical probes

Indoor and outdoor air pollution – meteorology-influence of solar radiation and wind fields – lapse rate and stability conditions – characteristics of stack plumes – effective stack height.

Characteristics and health effects of various air pollutant particulates (PM2.5, PM10) and gaseous pollutants (CO, NOx, SOx, etc)- their behaviour in atmosphere – monitoring.

Photochemical reactions – secondary pollutants.

Control devices for Particulate and Gaseous pollutants – applications.
