Uttar Dinajpur, West Bengal. The present report comprises of the Environmental Monitoring work covering the data of Ambient Air Quality, Noise Levels, Ground Water and Surface Water Quality during the period from 23/03/2015 to 19/04/2015. Page: 1 of 16 Environmental Monitoring Report at “Tantia Agro-Chemicals Pvt. Ltd., Village:Paschim Maheshpur, Dalkhola, Dist-Uttar Dinajpur. West Bengal. Chapter: 2 Ambient Air Quality Monitoring To quantify the impact of the proposed Project site activities on the ambient air, it is necessary at first to evaluate the existing ambient air quality of the environment. The existing ambient air quality, in terms of Particulate Matter 10 (PM 10), Particulate Matter 2.5 (PM 2.5), Sulphur dioxide (SO2) and Nitrogen dioxide (NO2), has been measured through a planned field monitoring.
