“…2 suggests similar levels of vapor-phase PCDD/F concentrations at Rural Site 1, Rural Site 2, and Urban Site 1 but higher particle-phase PCDD/F concentrations at Urban Site 1 than in the rural sites. The higher particlephase PCDD/F concentration at every sampling sites was due to the fact that more than 90% of PCDD/F congeners exist in particle phase in the atmosphere (Saral et al, 2015). However, the gas phase PCDD/F increase with PM 2.5 at LRT periods suggested that LRT not only brought particle phase PCDD/Fs to the sampling stations but also gas phase PCDD/Fs.…”

Winter monsoonal air masses traveling from Inner Mongolia to downwind nations can transport cold temperature and air pollutants. This study investigated the effects of the long-range transport (LRT) of air pollutants by northeastern monsoons and local pollution (LP) episodes on atmospheric PM 2.5 , polychlorinated dibenzo-p-dioxin (PCDD), and polychlorinated dibenzofuran (PCDF) concentrations in northern Taiwan during the winters of 2014 and 2015. Air samples were collected in rural (Rural Site 1 was mountainous; Rural Site 2 was coastal) and urban (Urban Site 1 was urban; Urban Site 2 was suburban) areas in northern Taiwan as well as at a background site (Lulin Mountain) in central Taiwan. Atmospheric PCDD/F concentrations measured at different sites ranged from 11.0 ± 2.70 to 39.7 ± 22.7 fg international toxicity equivalency quantity (I-TEQ) m -3 in 2014 and 7.99 ± 5.58 to 17.5 ± 12.3 fg I-TEQ m -3 in 2015. During LRT and LP, the proportion of PCDFs was higher than that of PCDDs. Rural Site 1 (122 pg I-TEQ g

<p>In this study, the seasonal variation of atmospheric concentrations of PCDD/F and Dl-PCB and the effect of meteorological factors on concentration were investigated. Ambient air samples were collected monthly between May 2011 and October 2013 by using high volume samplers. Based on these samples, average PCDD/F and dl-PCB concentrations were obtained as 1482 fg/m3 and 4983 fg/m3 respectively. PCDD/F congeners did show seasonal variations. 58% share in total PCDD/Fs belongs to winter season while 4% to summer season. No significant seasonal change has been observed for dl-PCBs. 92% (1397 fg/m3) of PCDD/Fs were detected in particulate phase while 20% (926 fg/m3) of dl-PCBs were found in particulate phase. Strong negative correlations were obtained between all homolog groups and T, UV, SR. Correlation between five-chlorinated dl-PCBs, the most abandoned homolog group, with T, UV and SR generated positive meaningful correlation. No meaningful correlations were observed with other parameters. Correlations with particle phase were found to be more meaningful compared to gas phase for both PCDD/Fs and dl-PCBs.</p>

“…Several field measurements were conducted to determine the gas/particle partitioning for SVOCs (Cincinelli et al, 2014;Saral et al, 2015;Wang et al, 2014 andXie et al, 2014a,b). In those studies, filter-sorbent samplers were used extensively, in which air was pulled through a filter to collect the particle-phase SVOCs and then followed by a sorbent to collect the gas fraction.…”
