在制造重铬酸钠或钾的生产过程中,或电镀工厂中经常有含铬粉尘和铬酸雾蒸气析出。生产工人在防护不良的环境下长期接触,可导致鼻部病变,特别是鼻腔鼻中膈粘膜可呈现充血、糜烂、溃疡、甚至穿孔。我们对某重铬酸盐类制造厂341名生产工人进行了调查,发现有200名生产工人有不同程
Chromium dust and chromic acid mist vapors are often precipitated in the production of sodium or potassium dichromate or in electroplating plants. Long-term exposure of production workers in poorly protected environments can result in nasal lesions, especially in the nasal septum and diaphragmatic mucosa that can present congestion, erosion, ulceration, and even perforation. We conducted a survey of 341 production workers in a dichromate factory and found that there are 200 workers who have different processes
