建议还是按照类似的PCDDF的TEF值进行计算吧，请参考这篇文献
Gullett B.K., et al., Environ. Sci. Technol. 2010, 44, 394–399

PCDD/F TEQ values were calculated based on World
Health Organization (WHO) toxic equivalency factors (TEFs)
(16) and PBDD/F TEFs were assigned as those of their
PCDD/F equivalents (14). This latter assumption was based,
in part, on recently published in vitro bio- and immunoassay
assessments ofPBDD/Faryl hydrocarbon (AhR) agonist
properties and dioxin-like toxicity (9, 10, 26). The International
Programme on Chemical Safety (IPCS) of WHO
suggested that until TEFs for PBDD/PBDF are established,
the preliminary use of the same TEF values as described for
the chlorinated analogues appears to be justified (14). Initially,
filters and PUFs were extracted separately to determine the
distribution of the targets. Since virtually all of the target
analytes were found on the filter, subsequent analyses were
done with combined filters and PUFs. This also minimized
the impact of copious nondetects on the PUFand their effect
on the emission factor calculation when nondetects were set
to the detection limit.
