The study is comprised of air quality monitoring during the day time at three municipalities of Banepa, Dhulikhel and Panauti in Kavre district of Nepal. The study was conducted in order to establish a baseline air quality data for those municipalities as the first time ever in the district. In each of the municipalities three air monitoring stations were established representing Industrial, Commercial and Residential areas. Total Suspended Particulate Matter, PM10, PM2.5, SO2, NO2 and Noise level have been estimated which spanned 7 months and a total of 63 to 126 days reflecting all the three...
The study is comprised of air quality monitoring during the day time at three municipalities of Banepa, Dhulikhel and Panauti in Kavre district of Nepal. The study was conducted in order to establish a baseline air quality data for those municipalities as the first time ever in the district. In each of the municipalities three air monitoring stations were established representing Industrial, Commercial and Residential areas. Total Suspended Particulate Matter, PM10, PM2.5, SO2, NO2 and Noise level have been estimated which spanned 7 months and a total of 63 to 126 days reflecting all the three seasons. High Volume air Sampler, Low Volume air Sampler, Personal air Sampler and SPL meter were used for estimation of the pollution concentration. The mean level of TSP, PM10, PM2.5, SO2 and NO2 was found to be 314.90µg/m3, 188.02µg/m3, 155.75µg/m3, 38.37µg/m3and 24.6µg/m3 respectively. The seasonal trend in pollution levels show that winterre-monsoonmonsoon. The pollution concentration trend noted among the areas was commercialindustrialresidential on almost all the occasions. The study also found that, the traffic noise in Banepa is very high with a range of 52.5 to 110.2 decibel.
