Abstract Agriculture is estimated to have the greatest labour force in the world with over one billion people and employs about 450 million waged woman and men workers. In agricultural operations dust are generated due to seasonal work activities such as ploughing, seed bed preparation, sowing, harvesting and threshing. The severity of the effects of dust in terms of human health depends on the source of dust particles, particle sizes, dust concentration and exposure time. Due to continual exposure to breathing hazards, farm workers suffer from breathing difficulties such as asthma, organic dust toxicity syndrome (ODTS) etc. The present study was undertaken for environmental dust concentration evaluation during agricultural operations such as ploughing, seed bed preparation, sowing, harvesting and threshing in Rabi season and to identify the most hazardous dust producing operation and introduce dust protective measures. In the present study, Total five locations were selected for the measurement of dust concentration on each operation during Rabi season. Dust concentration was measured for 2.5 µm, 10 µm and total dust particle size by a real - time personal dust monitor and dust concentration for 5 µm particle size was measured by gravimetric respirable dust monitor at breathing zone of worker’s for 15 min. The measured dust levels were compared with standard exposure limits. It was found that, the respirable dust concentration varied from 0.512 mg/m3 to 3.353 mg/m3 in four different field operations and from 0.076 mg/m3 to 3.141 mg/m3 for three locations in threshing operation. The maximum values of 3.353 mg/m3 and 3.141 mg/m3 were above standard exposure limit of 3 mg/m3 as per ACGIH but below 5 mg/m3 as per OSHA in harvesting and threshing operation respectively. Five different types of dust protectors were selected for suitability tests. A Performa was designed to record different parameters to observe the suitability of dust protectors in terms of breathing resistance, air leakage from sides, dust filtration, feeling of tightness on face, rate of sweating, spoil and smudge of skin during use and any communication problem. Each of the workers was asked to give a comparative rank as per his preference for suitability. The comparative rank was converted to comparative acceptability score. It was observed that, the mask 5 i.e. cloth type dust protection mask was found most suitable and acceptable by the agriculture workers and is recommended for use in threshing operation. It will be helpful for agriculture workers to provide protection against the respirable dust. Besides, it is a cost effective and easily available.
