Exposure to dust among agricultural workers.

The authors present results of studies of occupational exposure to dust in agriculture, conducted for the first time from the aspect of work site. Two work sites, typical of Polish agriculture, were considered: a tractor driver on a large state owned farm and a farmer on a private family farm. The studies covered all occupational activities performed within the annual work cycle. The results of the studies showed that the working conditions in agriculture were hazardous and exposure to dust was of a changeable character. This is due to the varied levels of dustiness according to the type of occupation and unequal distribution of working time.
