调查帕隆藏布流域水体水质和水化学特征,分析水体常规指标,包括pH、电导率、含盐量（SAL）、总溶解固体（TDS）和溶解氧（DO）.测定水和底泥样品23种金属元素,Ca是水体主要阳离子,水体离子均含量趋势符合Ca>Mg>Fe>K>Na>Mn>Zn>Ba>V>Pb>Cr>Ni>As>Cu>Co>Se>Hg>（Mo、Ag、Sb、Tl、Cd和Be）.采用《地表水环境质量标准》（GB3838—2002）及地质累积指数（Igeo）分别评价水质和底泥状况.水体Cu、Se、As、Zn、Cd和Pb达Ⅱ类及以上标准,Hg是潜在污染物,Hg含量略高(最高达0.3μg·L-1),但低于《国家生活饮用水卫生标准》(<1μg·L-1)限量;底泥重金属污染程度较轻,Zn、Pb、Ni、Cu和Cd几乎不存在污染,As是底泥主要污染物,其次为Cr.综合各项指标表明帕隆藏布流域水体水质良好.https://kns.cnki.net/kcms/detail/detail.aspx?dbcode=CJFD&dbname=CJFDLAST2018&filename=HJHX201804031&uniplatform=NZKPT&v=CpXbOzL4vZMvH%25mmd2B3FnVaAyVfZkpbjA8muwwPYj4D1BkSgbhJlOf%25mmd2BiFuBaXKHR1gIs
