[Clinical analysis of 24 cases of occupational chromium rhinopathy].

Occupational chromium rhinopathy is chronic nasal damage caused by chromic anhydride, chromate and dichromate 6-valent chromium compounds. In 2016, 700 people who were exposed to chromium slag in steel plant were checked out. 24 people were found to have nasal injuries. The expert group confirmed 1 case of occupational severe chromium rhinosis and 23 cases of occupational mild chromium rhinosis.There was no significant difference in the incidence, type of work and duration of injury among 24 patients (P>0.05) . Active measures should be taken to prevent chromium rhinopathy and the technological process should be reformed. Occupational health education and occupational health monitoring should be strengthened to avoid exposure of chromium and its compounds through nose and respiratory tract, and to reduce or eliminate the occurrence of chromium rhinosis.
