碘是一种易挥发、有腐蚀性、极毒的褐色结晶。生产车间空气碘最高容许浓度我国未做规定,苏美国家卫生标准为1.0毫克/立方米。碘对作业工人的健康危害比较严重,对皮肤的慢性损害尤为突出。因此,为贯彻“预防为主”的卫生工作方针,摸清碘危害与作业场所空气碘浓度的关系,测定空气碘浓度是很必要的。空气碘浓度测定方法国内未见报导。国外有人主张用硫代硫酸钠滴定法测定,我
Iodine is a volatile, corrosive, extremely toxic brown crystal. The highest allowable concentration of air iodine in the production workshop is not stipulated in our country. The standard of health in the Soviet Union and the United States is 1.0 mg / m3. Iodine is more harmful to workers’ health and chronic skin damage. Therefore, in order to carry out the principle of “prevention-based” health work and find out the relationship between the iodine hazard and the concentration of iodine in the workplace, it is necessary to determine the concentration of air iodine. Air iodine concentration was not reported in the country. Some people abroad advocated using sodium thiosulfate titration method, I
