Background and Aims: Agricultural workers are expose to various hazardous particles. Tractor and Combine drivers’ exposure to particulate matters causes vast types of diseases. This study aimed to evaluate combine driver’s exposure to respirable dust. Materials and Methods: In this descriptive-analytical study, 44 Combine drivers in Shahindej city and its surrounding agricultural fields, were included. The air sampling from breathing zone of drivers was taken applying NIOSH0600 method. statistical analysis was performed using SPSS16 with t-test and Partial Correlation. Results: The mean concentration of personal and environmental PM4 was 22680 and 521.8 µg/m3 respectively. PM4 level in non-cabin combines was 63% higher than cabined machines, which was 63.5% and 37.7% for PM2.5 and PM1 respectively. Significant relations were found between PM4, PM2.5 and PM1 with each other. High correlation was exists between temperature and mentioned PMs. Conclusion: Drivers’ exposure to particulate matter was higher than permissible exposure limits and required improvement. As a controlling method, upgrading of machine cabins and implementation of ventilation system could be suggested. It’s suggested that the future researchers adjust their objectives to chemical characterizing of PMs and evaluation of biomarkers of particulate matter in exposed workers’ blood and urine samples.
