India is a second largest rice growing countries in the world. A large number of unskilled laborers are
employed for paddy processing. In rice mills, most of the workers have shown adverse health effects associated with
occupational exposure to rice husk dust (WHO, 1968). Present study was conducted to determine the hematological
disorders in rice mill workers in rural/urban areas of Uttar Pradesh. Total numbers of 100 blood samples were collected
from rural and urban area from rice mill workers of Lucknow district. Majority of hematological test parameters
showed reduced levels in rice mill workers. This study would be helpful in preventing longstanding harmful effects of
such exposures. It is also useful for preventing environmental risks. It is concluded that rice husk dust causes
deterioration of hematological parameters in subjects working at rice mills. The findings of this study recognized the
role of rice husk dust for a longer duration in decline of hematological parameters as per tests conducted among rice
mills workers. Significant hematological disorders were observed in rice mill workers.
