Name of Department

Air Pollution Unit


  • To assess the exposure to various air pollutants at the places of work 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 measure to minimize the exposure and associated risks. To create awareness/communicate the associate risks of exposure to air pollutants to the exposed groups/general population through various media like radio and TV programmes.

Functions of the Department

  • Air monitoring for various air pollutants like Volatile organic compounds, Poly Aromatic Hydrocarbons, aldehydes, esters and ketones. Inorganic gaseous pollutants ( NOx, SO2, phosgene, carbon disulfide, so etc) and particulate matter ( RPM / TSPM ) using advance-sampling and Analysis using modern analytical instruments like GC/GC-MS/HPLC.
  • Organize / participate in various teaching / training programmes for various population groups such as PG students/academicians/industrials medical officer.
  • Communicate to masses through radio / TV programmes for creating awareness.
