COMPARATIVE STUDIES OF THE AIR POLLUTANTS IN THE INDUSTRIAL AREA OF BADLAPUR AND DOMBIVLI REGION OF THANE DISTRICT FOR THE PERIOD OF THREE YEARS FROM 2018 - 2020

Abstract

The Industrial (MIDC) area of Badlapur and Dombivli have around 870 chemical and dyesmanufacturing Industries, these industries release numerous air pollutants in surroundingenvironment. This air pollutant content is required to be below the standard norms given byNAAQS. Ambient air monitoring station of MPCB monitors the Sulfur dioxide (SO2), Oxides ofNitrogen (NOx), and Respirable Suspended Particulate Matter (RSPM) regularly in the area. Theassessment was done at three sites, BIWA house Badlapur, CETP and MIDC Dombivli for theduration of three years from January 2018 – December 2020. Results obtained from the study haveshown that RSPM level of all the stations were decreased several fold amidst lockdown comparedto the previous years. The level of Sulfur dioxide and Oxides of Nitrogen were also drasticallydeclined during the lockdown period. Hence the Air Quality Index (AQI) recorded at all threestations is satisfactory to moderate for the year 2020.
