该研究通过对三岔河两支流水样、底质进行采样分析，探讨了河流水质、底质中砷污染特征及其相互关系。结果表明，两支流水质砷浓度远超地表水环境质量标准V类，且花石头河远高于天生桥河，前者是后者的6倍，其差异性达到显著性水平。花石头河水质砷浓度是丰水期高于平水期；天生桥河砷浓度是丰水期低于平水期。两支流水质砷浓度丰水期波动大，平水期则趋于平稳。在丰水期的前期，两支流底质砷的浓度最高，然后逐渐降低，到丰水期的后期河流底质砷浓度接近于平水期底质砷的浓度。研究还表明，花石头河底质砷对水质中砷有显著性正相关关系；而天生桥河，底质砷浓度对水质砷浓度呈显著性负相关关系。

Based on sampling and analyzing the water sample and sediment of two tributaries in Sanchahe River, the arsenic pollution characteristics of the river sediment and water quality and their relations were discussed. The results showed that the arsenic concentration of two tributaries surpassed the V class standard of surface water, and the arsenic concentration in Huashitou River was six times higher than that of Tianshengqiao River, a significant distinction degree. The arsenic concentration in flood flow period was higher than of average flow period in Huashitou River, but the arsenic concentration in Tianshengqiao River was opposite. In two sampling periods, the arsenic concentration of the two tributaries in flood flow period fluctuated significantly and the arsenic concentration in average flow period is steady. The sediment arsenic concentration in the former period of flood flow pe- riod was the highest, and the sediment arsenic concentration decreases from then on. The sediment arsenic concentration in the later period of flood flow period was close to the sediment arsenic concentration of average flow period. Furthermore, there was positive significant correlation between the sediment arsenic concentration and arsenic concentration in Huashitou Rriver. However, there was negative significant correlation between the sediment arsenic concentration and arsenic concentration in Tianshengqiao River.
