Objectives-Increased concentrations of polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs) in pooled blood samples from workers at municipal waste incinerators have been reported.
This study was undertaken to confirm these results in individual blood samples from potentially exposed and unexposed workers at municipal waste incinerators compared with matched unexposed controls and compared with concentrations in the slag and fly ash from the municipal waste incinerators.
Methods-Concentrations of PCDDs and PCDFs were determined in the blood of 10 workers from an old municipal waste incinerator without adequate pollution controls, 11 workers from a newer incinerator with modern pollution controls, and 25 controls from the general population group matched for age (±10 years), sex, and race, and in the slag and fly ash from the older incinerator.
Significant increases of certain PCDDs and PCDFs were found in the blood of the workers from the older incinerator.
The workers from the older incinerator with the greatest exposure were found to have the most significant increases of the blood PCDDs and PCDFs.
No significant differences were found between the blood concentrations of the workers at the newer incinerator and the controls.
Conclusion-Occupational exposure to slag and fly ash from municipal waste incinerators may increase the blood concentrations of PCDDs and PCDFs.
