Primary Outcome Measures:
  • Investigate the dose-response relationship between benzene exposure and blood diseases in Shanghai workers. [ Time Frame: August 2003 - December 2009 ] [ Designated as safety issue: No ]
    Investigate the dose-response relationship between benzene exposure and blood diseases in Shanghai workers


Secondary Outcome Measures:
