随着科学技术的发展,稀有金属广泛被应用到电子学、半导体、光学等部门,特别是铯化合物例如氢氧化铯、砷酸铯已被利用。因此研究铯化合物的毒性以及制订车间空气中的卫生标准具有重要的现实意义。在文献中已报导了氯化铯、氢氧化铯、硝酸铯,碳酸铯、硫酸铯的毒性,但是关于砷酸铯的毒性还未见报导,本文主要对砷酸铯进行了急性、亚急性毒性实验,结果如下:
With the development of science and technology, rare metals are widely used in electronics, semiconductors, optics and other departments, especially cesium compounds such as cesium hydroxide, cesium arsenide have been used. Therefore, it is of great practical significance to study the toxicity of cesium compounds and to establish the hygienic standard in the air of workshop. The toxicity of cesium chloride, cesium hydroxide, cesium nitrate, cesium carbonate, and cesium sulfate has been reported in the literature. However, there is no report about the toxicity of cesium arsenate. In this paper, acute and subacute toxicity of cesium arsenate Experiment, the result is as follows:
