Diesel emissions have been classified as carcinogenic to humans and have been linked to increases in cases of respiratory and cardiovascular diseases. Scientific evidence has reported that the highest levels of exposure to diesel emissions occur in underground mining activities. Although these investigations have exposed this problem, they have been carried out in countries that have specific regulations, and there is still little research that addresses this situation in developing countries that do not have a specialized regulatory framework on the matter. The objective of this study was to evaluate the occupational exposure to diesel particulate matter (DPM) in underground activities of a polymetallic mine located in Peru. In this research, the levels of exposure to DPM were determined using elemental carbon (EC), organic carbon (OC), total carbon (TC) and submicron particulate matter (PMS) as indicators, and an analysis of the correlations between indicators of DPM and factors influencing exposure levels were identified. To determine the exposure levels, similar exposure groups (SEG) were established based on the main activity. Full-time personal DPM monitoring was performed following the NIOSH 5040 method and MSHA recommendations. As for the PMS measurements, these were carried out using a real-time aerosol monitor. The results show that the mean EC concentrations for the SEG is in the range of 150.18 to 871.16 µg / m3, exceeding the DPM exposure limit by at least 8 times. The logarithmically transformed concentrations of EC and OC, TC, PMS were significantly correlated, with Pearson's correlation coefficients greater than 0.8 (p <0.01). Significant exposure differences are reported according to main activity (p <0.01). The exposures of scooptram operators were higher than the rest of GES. In the GES scooptram operator, exposures were higher according to factors such as age and the type of cabin (open or closed) of the equipment (p <0.05). It stands out that the average concentration of EC when the equipment had open cabins was 3.9 times higher compared to the cases where the operators used equipment with closed cabins.
