CPCB to Validate Sensor-Based Air Quality Monitoring System??
Rapid economic growth has brought many benefits to India; but the environment has suffered, exposing the population to serious air pollution. The consequences of pollution have led to poor urban air quality in many Indian cities. The air pollution and the resultant air quality can be attributed to emissions from transportation, industrial and domestic activities. Due to pollution, the ambient ...

Quantitative analysis of automotive exhaust gas by Fourier Transform Infrared spectroscopy
For monitoring gaseous emissions from muffler, instruments presently used can only measure quantitatively a given pollutant. Fourier Transform Infrared (FTIR) spectroscopy can provide quantitative and online real time analysis. Calibration of our FTIR spectrometer with CO, CO2, NO, NO2 and N2O was done and the limits of quantification obtained were shown to be as low as 80 ppm. The variation ...
