One hundred and thirty one workers occupationally exposed to phosphorite and apatite dusts and a control group underwent repeated laryngological and cytological examinations of nasal mucosa smears. The clinical examination showed chronic simple or atrophic rhinitis. The cytological test revealed metaplasia of the respiratory epithelium towards squamous epithelium in all smears. Both the rate of catarrhal changes and the degree of epithelial metaplasia varied with the duration of exposure.
131名职业性接触磷矿石和磷灰石粉尘的工人以及一个对照组接受了鼻黏膜涂片的多次喉科和细胞学检查。临床检查显示为慢性单纯性或萎缩性鼻炎。细胞学检测在所有涂片中均发现呼吸上皮向鳞状上皮化生。卡他性改变的发生率和上皮化生程度均随接触时间的延长而变化。
