Ambient Air Quality and Noise monitoring in Haridwar City of Uttarakhand State (India)

In the present study, four parameters viz. RSPM, SPM, SO 2 and NO 2 were studied during October to December 2011, at three busy intersections of Haridwar city namely; Singh Dwar, Prem Nagar Ashram Chowk and Chandi Chowk to assess the impact of vehicular emission on air quality of concerned area. Noise levels were also monitored for sites with the help of Sound Level Meter. The minimum and maximum value for RSPM were recorded 86.20 µgm -3 and 99.75 µgm -3 at Prem Nagar Ashram Chowk and Chandi Chowk, respectively. The minimum 285.90 µgm -3 and maximum 400.50 µgm -3 value for SPM were recorded at Prem Nagar Ashram Chowk and Singh Dwar, respectively. The minimum 7.15 µgm -3 and maximum 9.10 µgm -3 values for SO 2 were recorded at Prem Nagar Ashram Chowk and Chandi Chowk, respectively. The minimum 9.99 µgm -3 and maximum 11.39 µgm -3 value for NO 2 were recorded at Prem Nagar Ashram Chowk and Chandi Chowk, respectively. In the present study, it was found that the noise level in all three different sites was higher as comparison to the standard prescribed limit of noise. (Sushil Bhadula and B. D. Joshi.
