摘　　要：目的探讨LEC评价法在陶瓷企业职业健康风险评估中的实用性。方法分别采用LEC评价法和定量分级法对陶瓷企业可能存在的职业健康危害程度进行评估、比较。结果压砖位作业岗位LEx,8 h为87.2 dB(A),进料作业岗位总尘时间加权平均浓度(CTWA)为1.9 mg/m3,窑炉出口作业岗位WBGT为29.3℃,窑炉出口作业岗位CO CTWA为0.09 mg/m3、短时间接触浓度(CSTEL)为1.01 mg/m3,CO2CTWA为1 134 mg/m3、CSTEL为1 362 mg/m3。结论 LEC评价法与定量分级法评估该陶瓷企业职业健康危害风险结果基本一致,其在陶瓷企业职业健康风险评估中具有其实用性,亦有其局限性。[ Objective] to explore the application of LEC method in occupational health risk assessment of the ceramic enterprises. [ Methods ] LEC and quantitative classification methods were used to evaluate and compare respectively for occupational health haz- ards in the ceramic enterprises. [ Results] LEx ,8 h of pressed brick-bit operating position was 87.2 dB（ A）, CTWA of total dust for feeding operating position was 1.9 mg/m3 , WBGT of furnace export position was 29.3 ℃, CTWA of CO in furnace export position was 0.09 mg/m3 ICSTEL was 1. 01 mg/m3, and CTWA was 1 134 mg/m3 ICSTEL was 1 362 mg/m3 for CO2. [ Conclusion] LEC method and quantitative classification method are basically consistently in results of assessing the risk of occupational hazards in ceramic en- terprises, and LEC method has its usefulness in occupational health risk assessment of ceramic enterprise, also has its limitations.
