摘要
本研究采用火焰原子吸收光谱法(FAAS)测定了车辆使用和维修场所附近的环境隔间(水和浅层沉积物)中微量元素(Cd、Cr、Cu、Pb和Zn)的浓度，目的是了解这些场所中微量元素的浓度是否较高。样品中发现的微量元素含量与CONAMA (Conselho Nacional do Meio Ambiente) 2005年第357号决议建议的最大值进行了比较，其中水和沉积物的最大值分别为2012年第454号决议建议的最大值。第11点和第13点是最关键的，它们的浓度高于水或沉积物样品中铜和铅元素的推荐浓度。沉积物样品中Cd和Cr的地质累积指数(Igeo)在第5点和第13点显示高污染至极端污染，而其他元素显示中度污染。
Trace Elements in Sediment and Urban Water Samples: an Assessment of Metal Pollution
In this study, trace elements (Cd, Cr, Cu, Pb and Zn) concentrations were determined by flame atomic absorption spectrometry (FAAS) in environmental compartments (water and superficial sediments) near places of vehicle use and maintenance, aiming to investigate if in these places the trace elements had high concentrations. The content of trace elements found on the samples was compared to the maximum values recommended by resolutions of CONAMA (Conselho Nacional do Meio Ambiente) n. 357 from 2005 for water and n. 454 from 2012 for sediments. Points 11 and 13 were the most critical, with concentrations higher than the recommended for the elements Cu and Pb, either for water or sediment samples. Geoaccumulation index (Igeo) for Cd and Cr in the sediment samples indicated high to extreme contamination in points 5 and 13, while the other elements indicated moderated contamination.
