The holy city of Haridwar is now emerging as a key industrial destination of the north India due to the presence of IIE Haridwar. Due to increased anthropogenic activities like vehicular emissions and industrial discharges in the Haridwar region, air pollution levels has raised greatly. The objectives of the study were (1) to determine the Spatial and seasonal variations of air quality in and around IIE, Haridwar and (2) to find out the Air Pollution Index (API). For this monthly monitoring of pollutant gases (SO2 and NO2) and particulate matter (SPM and RSPM) for two years (2012 and 2013) were done at six ambient air quality monitoring locations, one at each land use area (rural/agricultural, urban residential, protected area, industrial and commercial land use). The average SPM, RSPM, SO2, NO2 in the study area were found as 86.92 µg/m3, 81.04 µg/m3, 23.23 µg/m3, 24.73 µg/m3, respectively. It was observed that the average SPM levels exceed WHO standard limit of 120 µg/m3 at IIE Haridwar during study period. The average API during study period was 50.14 which indicates light air pollution. Meteorological conditions along with the distance from sources, particularly road transportation play a major role in deciding the ambient air quality over a region.

哈里瓦德SIDCUL综合工业区(IIE)附近颗粒物和气态污染物的时空变化:案例研究

由于IIE Haridwar的存在,圣城Haridwar现在正在成为印度北部的重要工业目的地。由于哈里德瓦尔地区的人为活动增加,如车辆排放和工业排放,空气污染水平大大提高。该研究的目的是(1)确定IIE,Haridwar及其周围地区空气质量的空间和季节变化,以及(2)找出空气污染指数(API)。每月对污染物气体(SO 2和NO 2)和颗粒物(SPM和RSPM)为期两年(2012年和2013年),分别在六个环境空气质量监测地点进行,每个土地使用区域(农村/农业,城市住宅,保护区,工业和商业土地使用一个) 。平均SPM,RSPM,SO 2,NO 2在研究区域中发现为86.92微克/米3,81.04微克/米3,23.23微克/米3,24.73微克/米3,分别。据观察,平均SPM水平超过了WHO的120 µg / m 3标准限值研究期间在IIE Haridwar工作。研究期间的平均API为50.14,表明空气污染轻。气象条件以及与源的距离,尤其是公路运输,在决定一个地区的环境空气质量方面起着重要作用。
