Characterization of Air Pollutants in Sub-Urban Area of Lucknow

Abstract

In Indian cities, air pollution are mostly visible now days due to rapid increase in urbanization, commercialization and industrialization. In the last few decades, the human behaviours have changed the global atmospheric condition, the present study deals with the quantitative effect of vehicular emission on ambient air quality during Dec2016-Feb 2017 in three locations viz. Indira nagar (Residential area), Alambagh (Commercial area), Amousi (Industrial area) of Lucknow city. The air quality was based on measuring Specific air pollutants namely Particulate Matter (PM2.5 & PM10), and gaseous pollutant sulphur dioxide (SO2), nitrogen dioxide (NO2) & Heavy Metal Lead (Pb) & nickel (Ni). The PM2.5 & PM10 level at all the locations were higher than the NAAQS limits. The SO2 & NO2 levels at Indira nagar were below than the NAAQS limits and in Almabhag & Amousi, NO2 concentrations were higher than the NAAQS limits. At all locations, the concentrations of the Heavy Metal Lead (Pb) and Nickel (Ni) higher than the NAAQS limit.
