作者对接触氧化铬(CrO_3)的158名生产工人的鼻腔损害和嗅敏度进行了观察,结果如下:嗅敏度测定作者根据国外资料介绍,让受测人员嗅装有不同浓度的苯酚水溶液瓶和蒸馏水对照瓶,用资料介绍的判分方法,来评价操作工人的嗅敏度。测定结果:男性嗅觉正常者观察组明显低于对照组,而嗅觉减退及丧失者观察组明显高于对照组,其中以31—40、41—50两个年龄组尤为明显; The authors observed nasal damage and olfactory sensitivity in 158 workers exposed to chromium oxide (CrO_3). The results were as follows: Determination of Odor Sensitivity According to foreign data, the test subjects were instructed to sniff the aqueous solutions of phenol in different concentrations And distilled water control bottle, with the information presented in the method of judgment, to evaluate the operating sense of smell. Determination results: the normal sense of smell of men in the observation group was significantly lower than the control group, while the sense of smell loss and loss of the observation group was significantly higher than the control group, of which 31-40,41-50 two age groups is particularly evident;
