To study the hazards of gem dusts and the epidemiological features of the occurrence of gem worker's silicosis (GWS).
Epidemiological investigation in a gem factory in Guangdong province was carried out.
The average dusts concentration in workshop was 2.3 mg/m(3), average free silica content was 94.64%. There were 47 patients diagnosed as silicosis. The prevalence of GWS was 4.58% (47/ 1,027). The age of patients suffering from silicosis and the duration of dust exposure were (27.04 +/- 3.25) years and (4.67 +/- 1.17) years respectively. Chest radiographic examination showed mainly small round opacities "q". The incidences of GWS complicated by pulmonary tuberculosis, spontaneous pneumothorax and pulmonary emphysema were 10.64%, 10.64%, 44.68% respectively.
The hazards of gem dust to workers might be serious. Higher incidence, younger age suffered from silicosis, shorter duration of dust exposure, more complications, and poorer prognosis in gem workers appeared to be the main epidemiological features of GWS in Guangdong.
研究宝石粉尘的危害及宝石加工工人矽肺（GWS）发病的流行病学特征。
对广东省一家宝石厂进行流行病学调查。
车间粉尘平均浓度为2.3mg/m³，游离二氧化硅平均含量为94.64%。确诊矽肺患者47例，GWS患病率为4.58%（47/1027）。矽肺患者年龄和接尘工龄分别为（27.04±3.25）岁和（4.67±1.17）年。胸部X线表现以小圆形阴影“q”为主。GWS合并肺结核、自发性气胸和肺气肿的发生率分别为10.64%、10.64%、44.68%。
宝石粉尘对工人危害可能严重。发病率较高、矽肺发病年龄较轻、接尘工龄较短、并发症较多、预后较差是广东GWS的主要流行病学特征。
