Abstract:Air pollution by polychlorodibenzo-p-dioxins/polychlorodibenzofurans (PCDD/Fs) and dioxin-like polychlorobiphenyls (dl-PCBs) in three residential areas north, west, and south of Da Nang airport, was determined by using passive air samplers containing polyurethane foam (PUF) discs with three-month sampling intervals from 2017 to 2020. The total toxic equivalents (∑TEQs) of the PCDD/Fs and dl-PCBs, using WHO2005-TEFs, were highest north of the airport (134 to 10610 fg WHO-TEQ/PUF day with an average of 1108 fg W… Show more
