Volume 4, Issue 4 , Autumn 2018, , Pages 483-492

http://dx.doi.org/10.22034/gjesm.2018.04.008

Abstract
  Different methods have been designed to calculate the air quality index in form of mathematical formula. But the formula designed by Central Pollution Control Board in 2014 is more robust to find out the air quality category. The index has been calculated based upon four parameters like particulate matters ...  Read More
