In order to evaluate the chromium contamination from tannery discharges into rivers in the State of Minas Gerais, Brazil, samples of fluvial sediment, vegetation and fish were collected and submitted to chemical analysis. The chromium content in the samples was measured by atomic absorption spectrophotometry. Metal inputs were related to effluent discharges into the rivers. High concentrations of chromium were found in samples when compared with controls. Sediment investigations indicated strong enrichment and high geoaccumulation indices, while chromium concentrations in the analyzed vegetation were higher than those normally found in these materials. Chromium levels in fish exceeded 35 times the Brazilian recommendation value for human intake.
为了评估巴西米纳斯吉拉斯州制革厂排放物对河流的铬污染情况，采集了河流沉积物、植被和鱼类样本并进行化学分析。通过原子吸收分光光度法测量样本中的铬含量。金属输入与河流中的废水排放有关。与对照相比，样本中发现了高浓度的铬。沉积物调查表明有强烈的富集和高地累积指数，而分析的植被中的铬浓度高于这些物质中通常发现的浓度。鱼类中的铬含量超过了巴西人类摄入量建议值的35倍。
