dc.description.abstractA study about household dust is being conducted to determine the level of metal contamination in the São Paulo Metropolitan Area (SPMA). The SPMA, with 18 million inhabitants, is one of the largest urban areas of the world, with serious environmental problems, due to the great amount of industries, heavy traffic and the disordered growth of population. The pollutants originate from a multiplicity of indoor and outdoor sources. Indoor sources are originated from residual (hair, skin scales), pets, human activities, construction materials, and furnishings as well as biological material (pollen, insect parts).and outdoor pollution, usually from the urban traffic. The pollutant mixture involved in numerous physical and chemical processes and changes its characteristics with time. Its composition and concentration depend on the strengths of indoor sources, the concentration of pollutants outside and the properties of ventilation and air-conditioning systems. It is well recognized that many metals have chronic effects on humans, in particular toddlers, who are at an higher risk compared to adults because they engage in greater hand to-mouth activity and their neurological systems are still developing. The household dust samples were collected from different localities, using vacuum cleaner, and sieved up to particle size <63μm, which were then analyzed for 7 elements by X-ray fluorescence technique. The fundamental parameters method (FP) was applied and the simple pressed powder technique for sample preparation was used. The concentrations preliminary results of metals in the household dust were Cr, 18-188 μg g-1; Mn, 119-369 μg g-1; Fe, 372-1464 μg g-1; Ni, 33-85 μg g-1; Cu, 42-303 μg g-1; Zn, 156-1369 μg g-1 and Pb, 26-160 μg g-1.
