Ambient air quality monitoring (AAQM) is required to determine the existing quality of air, evaluation of the effectiveness of control programme and to identify areas in need of restoration and their prioritization.

Industrial activities, Vehicular Movement and other activities are sources of pollution. It is necessary to monitor pollution level concentration at regular interval to control, reduce and prevent damage to environs.

Ambient Air Monitoring and Emissions Measurement

Air quality monitoring is carried out to assess the extent of pollution, ensure compliance with national legislation, evaluate control options, and provide data for air quality modeling. There are a number of different methods to measure any given pollutant, varying in complexity, reliability, and detail of data. These range from simple passive sampling techniques to highly sophisticated remote sensing devices. A monitoring strategy should carefully examine the options to determine which methodology is most appropriate, taking into account initial investment costs, operating costs, reliability of systems, and ease of operation.

The major Parameters for AAQM:

Particulate Matter

  • Total Particulate Matter
  • Particulate Matter >PM10
  • Particulate Matter ≤PM10
  • Particulate Matter PM2.5

Main Gaseous Parameter

  • Sulphur dioxide SO2
  • Oxides of Nitrogen Nox
  • Hydrochloric Acid HCl
  • Chlorine
  • Hydrocarbons HC
  • Carbon monoxide CO

Instruments for Ambient Air Quality Monitoring:

  • Respirable Dust Sampler
  • High Volume Sampler
  • PM2.5 sampler
  • Handy Air Sampler
  • Personal Air Sampler
  • Impinger Module with Flow meter
