Epidemiological study on Kaolinosis
摘要
Abstract
Objective To study the harmfulness of Kaolin dust and the incidence of Kaolinosis.Methods A cross-sectional epidemiological investigation was carried out in 5 Kaolin processing enterprises and 622 Kaolin dust-exposed workers in Maoming city.Results The overproofrate of short time allowable concentration (C-STEL) was 2.53％,while the overproof rate of time-weighted average concentration (C-TWA) was 1.90％.The content of free silicon dioxide (SiO2) was 1.25％ on average in Kaolin dust.Nine cases of Kaolinosis in stage 1 were detected in 622 cases of dust-exposed workers in a rate of 1.45％.The sufferers were all of Kaolin packers in average age of 47.43 years old and average time of dust exposure in 13.91 years.Patients with Kaolinosis had cough (66.67％),sputum (66.67％),chest pain (33.33％),and other symptoms.The main clinical signs were dry rales (33.33％) and coarse breath sounds (22.22％).X-ray chest films showed small circular shadows in a diameter between 1.5 to 3.0 mm,which were called in "q" shadows.The rate of damage in pulmonary ventilation and loss or most loss of labor capacity was 33.33％ respectively.Conclusion The Kaolin dust has more serious harmful to the health of exposed workers.Kaolinosis is featured by more symptoms,signs and "q" shadows in chest X-ray film,damage of pulmonary ventilation and evident loss of labor capacity.It is recommended to list Kaolinosis in the classification and catalog of the national occupational diseases.关键词
