Heamatological parameters of rice mill workers in Thiruvarur District: A Case study
Rice is the staple food for most of the population especially in south India. It is the largest source of the food grains consumed with calorific value. Rice milling is the oldest and the largest agroprocessing industry of the country. A large amount of dust is generated, especially during the milling processes, and the labourers involved are exposed, which causes health problems including lung diseases and breathing problems. Perusal of literature proved that study on such aspects are scanty. Hence it was planned to evaluate the haematological parameters associated with occupational exposure to rice husk dust. In this study a group of 75 exposed labourers working in the rice mill, and another group of 30 healthy workers in villages of Thiruvarur district were randomly selected with age group of 25-35, 35-45 and 45-55 years. They were interviewed using standardised questionnaire and haematological parameters were evaluated. The role of rice husk dust exposure for a longer duration declined majority of haematological parameters (Haemoglobin, RBC, MCV, MCH, MCHC and Platelets) in rice mill workers. It is concluded that the rice husk dust causes adverse effect on haematological parameters in rice mill workers. The findings suggest that there is the urgent need of care for the rice mill workers to prevent occupational health hazards.
