Abstract: Indoor-outdoor-personal particulate matter (PM) sampling was conducted in five selected welding workshops of Durg-Bhilai area, Chhattisgarh. Indoor-Outdoor-Personal PM<sub>5</sub> and Indoor-Outdoor PM<sub>10</sub> samples were collected using recommended methods and instruments for PM monitoring. O/I ratios, correlation coefficient values, infiltration factors, and intercept values are calculated between indoor-outdoor concentrations of PM<sub>5</sub> and PM<sub>10</sub>. In some cases, indoor concentrations have been found to be 2-3 times higher than outdoor PM concentrations. Personal PM<sub>5</sub> concentrations have been found highest among Indoor-Outdoor-Personal PM<sub>5</sub> levels and positively correlated with indoor PM<sub>5</sub> concentration and not much positive correlation with outdoor PM<sub>5</sub> concentration.
