NEVES, Eduardo Borba; MENDONCA JUNIOR, Nelson and MOREIRA, Maria de Fátima Ramos. Exposure assessment to metals in an armament repair shop of a military organization. Ciênc. saúde coletiva [online]. 2009, vol.14, n.6, pp.2269-2280. ISSN 1413-8123. http://dx.doi.org/10.1590/S1413-81232009000600036.
The aim of this study was the occupational exposure assessment to lead and manganese of workers in an armament repair shop 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 μg m-3). The biological indicators revealed that five of the nine employees presented Pb-S levels that suggested an environmental exposure to lead (values between 5 and 10 μg dL-1). It can be concluded that there is a small occupational exposure to lead and manganese in the superficial treatment repair shop. This exposure is influenced by weather conditions and the variable demand of work.
