In auto paint workshops there are several chemical, physical and biological agents that are harmful to health, making it essential to guarantee the well-being and safety of workers. In this sense, the assessment of the Indoor Air Quality (IAQ) of these places, in an associated context of occupational health, proves to be important. The present study had as main objective to evaluate the occupational exposure of workers in an automobile painting workshop to particles and air pollutants. The data collection consisted of the evaluation of air quality, using for this purpose, the assessment of atmospheric pollutants carbon monoxide (CO), carbon dioxide (CO2), Volatile Organic Compounds (VOC), formaldehyde (CH2O), carbon dioxide sulfur (SO2), nitrogen dioxide (NO2), hydrogen sulfide (H2S) and particulate matter (PM2.5, PM10, breathable and inhalable particles) and the meteorological variables temperature and relative humidity. The collected data was processed using the statistical software IBM SPSS version 27.0. The interpretation of the statistical tests was performed with a 95% confidence level for a maximum random error up to 5%. We found that the concentrations of inhalable particles recorded in some workstations exceeded the legally established exposure limit value. IAQ should be a priority concern for the government and for all professionals working in the area of Occupational Health and Safety having in mind the implementation of measures that promote the continuous improvement of the IAQ of the facilities, thus guaranteeing a good assessment and monitoring of workstations, preventing atmospheric pollutants from reaching concentrations that could put workers' health at risk.
