| 摘 要： | 本实验系用220V交流电源和直径2.0mm紫铜线为接触电极,在新鲜尸体腹部皮肤上做电烧伤实验。用原子吸收分光光度计对电烧伤皮肤中铜元素含量进行测定。结果表明电烧伤皮肤铜元素含量最高可达137.90μg/g。经10%福尔马林溶液固定40天以上的电烧伤皮肤铜元素含量有昕降低,但仍较正常皮肤含量为高。电烧伤皮肤铜元素含量以电流斑处为最高。本实验为电烧伤皮肤金属元素的定性与定量分析,检材的提取和处理,提供了一个较好的方法,有利于判定案件的性质和确定接触电极的金属种类。

| Abstract: | The electrical injuries of the corp abdominal skin were formed by contacting with a living copper wire probe of 2mm in diametre and 220V AC electrical current.The quantity of copper elements deposited on the skin was measured using atomical absorption spectrophotometer.Results indicated that the highest content of copper elements deposited on the injuried skin was 137.90μg/g.The content of copper elements deposited on the injuried skin reduced to 13.33μg/g,once the skin samples were fixed in 10% neutral formalin longer than 40 days.But this quantity is still higher than that of the normal skin. |
