摘要
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。
mAg released from normal operation of the Daya Bay nuclear power plant had been assessed the critical radionuclide to the environment. Availability monitoring and assessment of environmental impacts depend upon comprehension of the environmental behaviors. The 110mAg contents in various environmental media involving seawater, sediment, and some marine organisms are measured in the West Daya Bay. Some environmental behaviors of 110mAg in the bay are discussed primarily. The result of screening biological indicator shows that the bivalvia and gastropod are probably appropriate objective for 110mAg environmental monitoring in the Bay. Sargassum is also available indicator in spring.
