摘要: Fly ashes from three municipal solid waste (MSW) incinerators in Taiwan were collected and segregated into different fractions for determining the physical chemical properties dioxin contents. Analysis of with each fraction indicated that fine particles had higher contents than large particles. Dioxin homologue components generated large-scale mass burn MSW incinerator less toxic small-scale batch incinerators, contained non-2,3,7,8 PCDD/Fs. Correlation analysis did not reveal a consistent trend between dioxins content ashes' properties, while strong positive correlation was found chloride content. Positive heavy metals such as copper zinc fly ash also established.
