In this study, the lead (Pb) levels in the air surrounding a battery repair shop were measured before and after installation of an exhaust system. Samples were collected in six and four points located at approximately 25 m and 500 m, respectively, from the battery repair shop. The limit of 1.5mg Pb.m-3 air was exceeded in 50% of the samples, ranging from 0.07 to 183.3mg Pb.m-3. After changes in the battery repair shop's interior layout and use of the exhaust system, three points were selected, corresponding to the highest concentrations found previously. The new levels ranged from 0.8 to 17.6 mg Pb.m-3, demonstrating a significant decrease in the lead content discharged into the environment after meeting the exhaust requirements.
