| 摘 要： | 本文报告了川江上游核排污水环境中９０ Ｓｒ 的监测结果。表明：９０ Ｓｒ 在河水和底泥中的含量与排污距离密切相关，在不同水生物种之间的蓄积分布有显著性差异，其中底泥和含钙高的生物对９０ Ｓｒ 有较强的浓集作用。所以，选用指示性物种能提高９０ Ｓｒ 监测灵敏度，是核污染监测的较好方法。

| Abstract: | Sr monitoring results in rivers receiving nuclear wastes are reported It is shown that 1 90 Sr content in water and sediment is closely related to the discharge distance,the cumulation distributing of 1 90 Sr in different hydrophytic organisms has distinct difference,there in sediment and high-calcium organisms have high capacity of concentrating 1 90 Sr So selected species as indicator can heighten the monitoring sensitivity and it is a better way in nuclear contamination monitoring |
