This study was conducted to examine the emission of aerosols during different agricultural operation like mulching, ploughing etc. Grimm aerosol spectrometer (11-R LAS) was used to measure the emission levels in terms of respirable, thoracic, alveolic and particulate matter concentration (PM10, ) on an experimental farm at Dabbda village in Hisar district of Haryana. Field was in dry condition after harvesting different operations were performed on the field emission was recorded at nose level of the tractor operator seated on his seat during different operations. | Evaluation of aerosol emission during different agricultural operations using spectrometer
