Abstract

We present an extensive investigation of pollutants respirable suspended particulate matter (RSPM) and suspended particulate matter (SPM), oxides of nitrogen (NOx), sulphur dioxide (SO₂) of Kidwai Nagar (S1), Darshanpurva (S2), Panki site (S3), Shastri Nagar (S4), Awas Vikas (S5) Meteorological parameters (temperature, relative humidity, wind speed and rainfall) present in air samples of Kanpur for Jan -2010 to Dec-2011. Each air pollutant is marked with a subscript k,d,p,s,a representing the name of area from which it belong to. In the present study, it was noticed that the observed values of SPM and RSPM levels at all selected stations exceeds the standard limits recommended by Central Pollution Control Board (CPCB) New Delhi, India. SO₂ and NOx levels in residential, industrial and commercial areas remain under recommended limits of CPCB. Correlation coefficients were calculated between different pairs of pollutants and Meteorological parameters. To identify the highly correlated and interrelated air quality parameters, t-test was applied for checking significance. Pollutants RSPM and SPM show significant positive correlations with p<0.01. An appreciable significant positive correlation have been found for RSPMk with SPMk, RSPMd, SPMd, RSPMp, SPMp, Noxp, SPMs and SPMa. A significant positive correlation was also found between wind speed and relative humidity. Relative humidity bears negative correlation with RSPMp, SPMp, RSPMs and SPMs Similarly rain fall also shows negative correlation with RSPMk, SPMk, RSPMd, SPMd, RSPMp, SPMp and SPMs.
