Inclusion of 13C12-labelled mono-, di-, and tri-chlorinated dibenzo-p-dioxin and dibenzofuran standards in US EPA methods 0023A/8290.

摘要: 13C12-Labelled mono-, di-, and tri-chlorinated dibenzo-p-dioxin (CDD) chlorinated dibenzofuran (CDF) standards have been tested for their applicability to standard EPA sampling analytical Methods 0023A/8290. These methods target analysis only the tetra- through octa-CDD/CDF homologues. Extension of isotope dilution method include those lower homologues is important toward obtaining reliable species concentration data on complete, mono- octa-chlorinated homologue profile. will improve our ability model poly-CDD/CDF concentrations understanding mechanisms formation, chlorination, dechlorination.
