Abstract: Agricultural dust are generated due to seasonal work activities such as ploughing, harrowing, cultivation, sowing, crop harvesting, threshing, and animal breeding. The present study was conducted to determine the dust levels during manual harvesting and threshing of wheat crop, the particle size distribution of dust and their comparison with the standard exposure limits. Four operational positions were selected for study such as workers harvesting with sickle, workers feeding crop into thresher, workers giving crop to feeder and workers collecting threshed grains. A real - time personal dust monitor was used to measure the dust levels in the breathing zone of workers for 10 min. It was found that of all the operations the dust level was highest for the workers feeding the crop into thresher i.e. 11.89, 4.67 and 3.20 mg/m3 respectively for inhalable, thoracic and respirable dust. These exceeded the standard exposure limits of 10 mg/m3 and 3 mg/m3 for inhalable and respirable fractions respectively. For other three operations, the concentrations were well below the threshold limit. In the particle size distribution there was relatively low mass proportion of particles smaller than 2.5 μm and contains high percentage of particles with diameters above 7 μm.
