Medical waste incinerator emissions are an important source of environmental PCDDs/PCDFs and may pose a significant health risk to local populations. In the present study, hospital employees who were considered most likely to have had the greatest exposure to the hospital's MWI emissions were identified and serum from these employees was analyzed for PCDDs/PCDFs/cPCBs. Results show that the employees' serum PCDD/PCDF/cPCB levels are within the range of background serum levels found in the U.S. and do not reflect excessive PCDD/PCDF/cPCB exposure. Based on these findings, it is likely that other employees at the hospital who had similar or less exposure to incinerator emissions would also not have elevated PCDD/PCDF/cPCB levels. Though it is possible that some of the hospital employees' past health problems (e.g. headaches, respiratory effects) may have resulted from exposure to MWI emissions, concerns regarding excessive PCDD/PCDF exposure appear to be unfounded.
