Definitions

  • the ambient air quality monitoring system instrument are used in the different locations of industries to measure the pollutant concentrations dispersed from industries.
  • the typical approach to provide satisfactory ambient air quality level in the specified locations or residential places is to measure pollutants emitting either from the industries, vehicular emissions or any other sources of emissions.
  • the ambient air quality will be in the form of either gaseous or particulate, the particulate measurement to be conducted by gravimetric technique and gaseous pollutions to be measured by either absorption and or adsorption techniques.
  • the measured values are then compared with safe or recommended National Ambient Air Quality Monitoring (NAAQM) guidelines specified as per MoEF .
  • NAAQM National Ambient Air Quality Monitoring
  • FIG. 2 illustrates a diagram 200 depicting an assembly of ambient air sampling unit.
  • the system 200 includes a PM10 environmental air sampler 202, a high volume air sampler 204, a first suction brush less blower 206, a PM2.5 environmental air sampler 208, a gaseous sampler 210, a second suction brush less blower 214, a temperature sensor 216, a weather station 220, velocity sensors 228a and 228b and a cyclone unit cone 230.
  • the PM10 environmental air sampler 202 incorporated with a PM10 environmental air sampler filter paper for separating the pollutant concentrations form the ambient air received from environment and retain the pollutant concentrations greater than 10 micron size.
  • FIG. 3 illustrates a diagram 300 depicting an assembly of a PM2.5 environmental air sampler.
  • the PM2.5 environmental air sampler 308 is incorporated with a PM2.5 environmental air sampler filter paper for measuring the pollutant concentrations smaller than 2.5 micron size in the ambient air.
  • the PM2.5 environmental air sampler filter paper is used for separating the pollutant concentrations from the received ambient air and retaining the pollutant concentrations smaller than 2.5 micron size.
  • the PM2.5 environmental air sampler 308 further coupled to the temperature sensor 316 for detecting an ambient temperature.
