This study elucidates the characterizations of polychlorinated dibenzo-p-dioxin and
polychlorinated dibenzofuran (PCDD/F) emissions from heavy duty diesel vehicles (HDDVs), diesel passenger vehicles (DPVs) and sport utility vehicles (SUVs) using chassis dynamometer tests. The tested SUVs, DPVs and HDDVs are vehicles of the top sale brands in Taiwan. The test procedures followed the driving pattern FTP-75 (federal test procedure), new European driving cycle (NEDC), and US transient cycle for the SUVs, DPVs and HDDVs, respectively. For the SUVs, DPVs and HDDVs, the mean PCDD/F emission factors were 2.28 (relative standard deviation, RSD: 55%), 1.48 (RSD: 64%) and 38.8 ng km-1 (RSD: 132%), respectively, with the corresponding mean emission factors (in total PCDD/F I-TEQ) of 0.12 (RSD: 58%), 0.08 (RSD: 74%) and 1.69 (RSD: 102%) ng I-TEQ km-1, respectively. OCDD, OCDF and 1,2,3,4,6,7,8-HpCDF (1,2,3,4,6,7,8-HpCDD for HDDV) were the dominant congeners in the vehicular emissions. Attributed to the impaired operating conditions of engine and the catalytic converter in cold-start tests, the PCDD/F emission factors of tested vehicles were greater than those of individual type vehicles in previous studies.
