Total suspended particles and 12 airborne metals were determined in 4 sampling sites in the industrial region of Médio Paraíba, Brazil. The geometrical means for the four sampling locals were (in units of microg/m3): 65.9 in Barra Mansa, 57.3 in Jardim Paraíba (Volta Redonda), 41.7 in Resende, and 48.9 in Volta Grande (Volta Redonda). These values are lower than levels previously determined in urban and industrial locals of the Metropolitan Area of Rio de Janeiro. For metals, the higher concentrations were obtained for Ca, Zn, Al, Fe, and Mg. Ca, Zn, and Al levels are higher than those determined in other industrial areas. These three metals are used in steel manufacturing, the main economical activity of the region. Enrichment factors for Zn, Cu, Cd, and Pb are higher than 10, suggesting an industrial input. Statistical analysis show a high correlation among Ca, Mg, Zn, Cr, Al, Mn, and Fe, all of them used as raw materials in steel manufacturing and/or accumulated as industrial blast furnace slag and steelworks slag.
在巴西米迪奥帕拉伊巴工业区的4个采样点测定了总悬浮颗粒物和12种空气中的金属。这4个采样地点的几何平均值（单位为微克/立方米）分别为：巴拉曼萨65.9、雅尔迪姆帕拉伊巴（沃尔塔雷东达）57.3、雷森德41.7、大沃尔塔（沃尔塔雷东达）48.9。这些值低于先前在里约热内卢大都市区的城市和工业地点测定的水平。对于金属而言，钙、锌、铝、铁和镁的浓度较高。钙、锌和铝的含量高于在其他工业区测定的含量。这三种金属用于钢铁制造，而钢铁制造是该地区的主要经济活动。锌、铜、镉和铅的富集因子高于10，表明存在工业输入。统计分析表明，钙、镁、锌、铬、铝、锰和铁之间存在高度相关性，所有这些元素都用作钢铁制造的原材料和/或作为工业高炉矿渣和钢铁厂矿渣积累。
