  1. The Establishment of Job Exposure Matrix in Shanghai工种接触矩阵的建立 Shouzheng XUE (薛寿征 教授) National Cancer Institute 美国国家肿瘤研究所, 职业与环境流行病学处 Shanghai Municipal CDC 上海市疾病控制中心

  2. Subject of Hazard Monitoring

  3. Employees Exposed to Occupational Hazards, Shanghai 1986

  4. Collect and Bending Record

  5. Transcript and coding

  6. Processes Collecting, Bending, Transcript Coding (Trade, Occupation, Hazard) Keying and Checking Cleaning-up Assign Sample Source Exclude ELV and Duplicate Rating IPF (trade code & occupation code) Regression and Prediction (Modification) Validation Individual and Group TWA estimation

  7. Coding, Reviewing, Keying

  8. First Prediction of Benzene JEM

  9. Second Prediction of Benzene JEMpaired t test, t=1.4346, P=0.1542

  10. Calculate TWA from Spot Sample • Using rate of Frequency of exposure to modifying the exposed level, Intensity for calculate TWA (time weighed average) • Using rate of Possibility of employee exposed to modifying the individual TWA obtain TWA of job group (JTWA) • Using validated data take TWA as gold Standard to verifying the calculated TWA and JTWA

  11. Usefulness of the JEM of Occupational Hazard Monitoring • Establish the database for hazards • Evaluate the status of occup. health • Supporting the diagnosis of occupa-tion diseases and occupation cancer • Setting priority and direction on work of occupation health • Basis for occupation epidemiology
