Air Pollution

Objective

  • To evaluate the exposure of various air pollutants at work places for high risk population groups and general population through ambient and indoor air monitoring.

  • To assess the health impairments due to exposure to air pollutants for the high risk population through exposure assessment and biological monitoring.

  • To look for safety measure for various air pollutant exposure and associated risks. To create awareness among the exposed groups/general population about the associated risks due to air pollutants exposure.

Functions of the Department

  • The main function of the department is to evaluate the effect of air pollutants on high risk as well as general population. To achieve this department involves in monitoring of various air pollutants like Volatile Organic Compounds (VOCs), Polycyclic Aromatic Hydrocarbons (PAHs), aldehydes, esters and ketones. Inorganic gaseous pollutants (Oxides of Nitrogen, sulphur dioxide, ammonia, and ozone etc.) and Respirable Suspended Particulate Matter (RSPM/PM10, PM2.5) using air monitoring sampler and analysis using modern analytical instruments like Gas Chromatography (GC)/ Gas Chromatography-Mass Spectrometry (GC-MSMS)/High performance Liquid Chromatography (HPLC) and Ultraviolet (UV) Spectrophotometer.

  • Organize and participate in various teaching/ training programmes related to occupational and environmental health for students, academicians and industrials medical officer.

  • Awareness about the air pollutants exposure and its associated risks factors among factory workers, local residents and students/ academicians.
