摘要(Abstract)：

在小浪底水库坝上约10 km处主航道上设置采样垂线,采集水体不同深度的样品,采用冷原子荧光光谱法和电感耦合等离子体质谱法测定了样品中汞、砷、铅、镉、铬、铜、锌、锰、镍等元素的质量浓度。结果表明,在所有样品中,铬、镉、锌、铅均未检出,汞、铜和砷的质量浓度分别为(0.95±0.44)ng/L、(0.35±0.07)μg/L和(1.12±0.20)μg/L,锰和镍的质量浓度分别为(0.14±0.06)μg/L和(0.59±0.09)μg/L。汞质量浓度随水深增加逐渐升高,至水深7.5 m处达到最大值,然后逐渐降低,在接近底层时重新升高,达到次峰值。其他重金属质量浓度呈现随水深增加而升高的趋势。健康风险评价结果表明,致癌物质砷引起的健康危害较高,风险值为10-6¹0-5a-1,底层水中砷的风险值接近国际辐射防护委员会(ICRP)推荐的最大可接受风险水平;非致癌物质汞、铜、镍和锰引起的健康风险分别为1.43×10-12a-1、0.31×10-10a-1、0.13×10-10a-1和0.45×10-12a-1,均远低于ICRP推荐的最大可接受水平。
