110mAg被认为是大亚湾核电站放射性流出物中对环境影响最大的关键核素 ,而对110mAg的有效监测和危害评价都赖于对其环境行为的了解。通过测定大亚湾水体、沉积物和部分生物体的110mAg含量 ,分析了 110mAg进入西大亚湾海域的大致过程、存在形式、水平分布和在各类生物体中的浓集系数。文章认为双壳类和腹足类软体动物是对110mAg长期环境监测的合适指示生物 ,马尾藻类则可作为春季补充监测的对象。
110mAg is considered to be the most important environmental nuisance to the radioactive effluent of Daya Bay Nuclear Power Station. The effective monitoring and assessment of 110mAg depend on understanding its environmental behavior. By measuring 110mAg of water, sediment and some organisms in Daya Bay, the general process, existence form, horizontal distribution and concentration coefficient of 110mAg entering the sea of West Daya Bay were analyzed. The article concludes that molluscs of bivalves and gastropods are suitable indicators of long-term environmental monitoring of 110 mAg, while the species of Sargassum can be used as supplemental monitoring in spring.
