K. Sugita et al., SURVEY OF POLYCHLORINATED DIBENZO-P-DIOXINS, POLYCHLORINATED DIBENZOFURANS AND POLYCHLORINATED-BIPHENYLS IN URBAN AIR, Chemosphere, 29(9-11), 1994, pp. 2215-2221
PCDD, PCDF and PCB concentration levels in urban air were measured by
HRGC/HRMS system. The seasonal variations in PCDD/DF and PCB were only
slight. The concentration levels of PCDD/DF in winter were higher tha
n in summer but concentration levels of PBC in summer were higher than
in winter. It seems that low chorinated biphenyls in back-ground evap
olate to air in summer. The TEqs in urban air were estimated by method
of Safe et al.. PCDF contributed to toxicity mainly in urban air.
