The aim of this study was the occupacional exposure assessment to lead and manganese of the workers in an armament repair workshop of a military organization. The air of the working environment was assessed in the environmental monitoring while the internal dose biological indicators for lead and manganese, in blood and urine, were used in biological monitoring. Metals concentration in filters and biological fluids were determined by electrothermal atomic absorption spectrometry. The results of the environmental monitoring showed lead and manganese levels above the TLV-TWA during the process of painting (313.33 g m-3) and solder (951 µ g m-3). The biological indicators revealed that five of the nine employees present Pb-S levels that suggest an environmental exposure to lead (values between 5 and 10 μ g dL-1). It can be concluded that there is a small occupational exposure to lead and manganese in the superficial treatment workshop. This exposure is influenced by weather conditions and the variable demand of work.Key words lead, manganese, air, blood, urine, exposure assessment
