Keyword:  肺功能陶瓷粉尘肺通气;
Abstract: 目的 探讨陶瓷粉尘作业工人肺功能损伤的特征.方法 采用美能(日本)AS507型肺功能仪,测定某陶瓷厂“无尘肺”的967名接尘工人(接尘组)和197名非接尘健康工人(对照组)的肺通气功能.结果 陶瓷粉尘总尘浓度为0.10 ~2.95 mg/m3,总尘浓度超标率为14.29%,呼吸性粉尘浓度超标率为3.57%;粉尘中游离SiO2含量为21.3% ~ 43.0%.接尘组VC、FVC、FEV 1、FEV 1%、FEF 25%和FEF 50%的数值均低于对照组,差异有统计学意义(P<0.05或P<0.01).接尘组肺通气功能损伤和小气道损伤的发生率均高于对照组,差异有统计学意义(P<0.05).接尘的吸烟者VC、FEV1和FEV1%数值与非吸烟者相比,差异有统计学意义(P<0.01).接尘工人肺通气功能损伤发生率为7.45%(72/967),其中轻度损伤者占98.61%(71/72),限制性肺通气功能损伤占97.22%(70/72).结论 陶瓷粉尘可引起接尘工人肺功能的损伤,其损伤程度以轻度为多,损伤类型以限制型损伤为主.肺功能损伤主要与粉尘、接尘工龄、工种和吸烟等因素有关.
