OBJECTIVETo analyze the monitoring results of the occupational hazard factors in workplaces in Zhejiang Province, China in 2006 - 2010.

METHODSDescriptive analysis was performed on the monitoring results of the occupational hazard factors in workplaces in Zhejiang Province from 2006 to 2010.

RESULTSFrom 2006 to 2012, the number of monitored objects for each occupational hazard factor increased gradually, and the qualified rate for each factor remained unchanged or rose slightly. The qualified rates for silica dust and asbestos dust were less than 60%. The qualified rates for benzene, toluene, and xylene, which were always the factors highlighted in the monitoring of toxic chemicals, were all above 85%. The numbers of monitored objects for hexane, hydrogen sulfide, and cyanide grew significantly in recent years. However, the qualified rates for physical factors, which mainly included high temperature and noise, were less than 70%, lower than those for chemical factors.

CONCLUSIONThe qualified rate is as important as the number of monitored objects in the monitoring of the occupational hazard factors in workplaces in Zhejiang Province, China. The acute and chronic factors, physical and chemical factors, and traditional and new factors should be balanced in monitoring.
