Abstract

The aim of this study was to provide a comprehensive risk assessment for medical waste incineration fly ash from another aspect through various leaching methods. The differences and connections between leaching concentrations achieved via the toxicity characteristic leaching procedure (TCLP), the physiologically based extraction test (PBET) and the sequential extraction procedure were also described. Heavy metal contents of the used medical waste incineration fly ash were 1.7–31 times higher than that from Japan, indicating poor medical waste management in China. The fly ash leaching concentration in the TCLP test exceeded the regulation value and can be characterized as hazardous waste under current regulations. However, the PBET concentrations were only 1/10 of the TCLP value or even lower, and the calculated ingested contents of all heavy metals were lower than tolerable daily intake, demonstrating that TCLP might have overestimated the environment risk to some degree. The leaching metal content of TCLP ranged from exchangeable to residual forms, and the leaching percentage varied from 7.75 to 92.55 %, while the content for PBET was equal to or lower than the exchangeable form.
