dc.description.abstractThe occupational exposure to mercury (Hg) was assessed in four cooperatives of recyclable materials by air sampling in nine areas (recyclable materials pile, scale, baling press machine, e-waste room, cafeteria, office, forklift, conveyor belt, and outside patio). Of the 83 samples, only 14.5% showed concentrations above the limit of quantification (LOQ) while 53% were between the LOD (limit of detection) and LOQ. Most values > LOQ occurred at Cooperative A, at the pile (0.032 mu g.m-3) and scale (0.029 mu g.m-3). The higher values recorded at this Cooperative might be associated with the unloading of fluorescent lamps on the day of sampling. In cooperative B, the concentration was 0.033 mu g.m-3 on the conveyor belt and < 0.003 mu g.m-3 in other areas. In cooperatives C and D, all samples showed values < 0.007 mu g.m-3. The Hg concentrations were low in areas of e-waste handling and storage, probably due to the small amount of material and way of processing. The results were below the occupational reference values, showing that the workers are not exposed to Hg. However, the sampling design might not have been comprehensive due to the discontinuity of the e-waste processing and the unpredictable occurrence of fluorescent lamps mixed with recyclable materials.eng
dc.description.abstractA exposição ocupacional ao mercúrio (Hg) foi avaliada em 4 cooperativas de materiais recicláveis por meio de amostragens de ar em 9 áreas (monte de triagem, balança, prensa, sala de resíduos de equipamentos eletroeletrônicos-REEE, refeitório, escritório, empilhadeira, esteira e pátio externo). Das 83 amostras, apenas 14,5% apresentaram concentrações acima do limite de quantificação (LQ) e 53% entre o LD (limite de detecção) e LQ. A maioria dos valores > LQ ocorreu na cooperativa A, no monte (0,032 µg.m -3 ) e balança (0,029 µg.m -3 ). Nos dias de amostragem houve descarregamento de lâmpadas fluorescentes, o que pode explicar os maiores teores de Hg nessa cooperativa. Na cooperativa B a concentração foi 0,033 µg.m -3 na esteira e < 0,003 µg.m -3 nas outras áreas. Nas cooperativas C e D todos os valores foram < 0,007 µg.m -3 . As áreas de REEE apresentaram baixas concentrações, provavelmente devido ao baixo volume de REEE e forma de processamento do material. Os resultados estiveram abaixo dos valores de referência ocupacional, indicando que os trabalhadores não estão expostos ao Hg. No entanto, o desenho amostral pode não ter sido abrangente devido à intermitência no processamento de REEE e à imprevisibilidade da ocorrência de lâmpadas fluorescentes no material reciclável.
