  • The certification of the contents (mass fractions) of seven polychlorodibenzo-p-dioxins (D48, D54, D66, D67, D70, D73, D75) and ten polychlorodibenzofurans (F83, F94, F114, F118, F121, F124, F130, F131) in low level fly ash, BCR-615


The report describes the preparation, the homogeneity and stability studies and the certification of polychlorodibenzo-p-dioxins and polychlorodibenzofurans in a low level fly ash (BCR 615). The analytical methods used for the homogeneity, the stability and the certification studies are summarised and all results are given. The certified values with their uncertainties are given in the table below; the associated uncertainties U were calculated from the combined uncertainties uc multiplied by a coverage factor (k=2) (see report).
