For a case study of environmental contamination, radiochemical activation analysis has been applied to the crucians collected in the Han River. Sixteen trace elements (Hg, Cd, As, Br, Cu, Na, K, Se, Cr, Hf, Rb, Fe, Zn, Co, La, and Cs) were separated into three groups using distillation and diethyldithiocarbamate extraction methods, and their contents were determined by a single comparator method. Compared with the values 15 years ago, the values for mercury and cadmium have been drastically decreased at the middle and lower part of the river, but no typical change is found in other elements.
针对一个环境污染案例研究，放射化学活化分析已应用于汉江采集的鲫鱼。采用蒸馏和二乙基二硫代氨基甲酸盐萃取法将16种微量元素（汞、镉、砷、溴、铜、钠、钾、硒、铬、铪、铷、铁、锌、钴、镧和铯）分为三组，并通过单比较器法测定其含量。与15年前的值相比，河流中下游汞和镉的值大幅下降，但其他元素未发现典型变化。
