“…In regard to particle-bound dlPCBs, no seasonal pattern was observed during the sampling campaign (Table 3), with concentrations and WHOTEQ 2005 values for each congener (Figure 6) being quite similar between the cold and warm periods. This result is in agreement with other studies [20], although there are papers reporting elevated concentrations during warm periods for PCBs in gas phase [38,64], assuming that PCBs evaporated more easily from soil to gaseous phase and could be transported long-range under high temperatures [38,70,71].…”

“…The relative abundances of these four compounds were 19.7-58%, 23.1-26.0%, 8.7-29.6%, and 2.2-7.7%, respectively. The results are in agreement with those from other studies in industrial sites in Shanghai [55] and Anshan [38], China, in Seoul, Korea [64], and in Umm-Al-Aish oil field, Kuwait [20]. Seasonal variations of dioxins are presented in Figure 5 and according to the Mann-Whitney test only 1,2,3,4,6,7,8-HpCDD, 1,2,3,4,7,8-HxCDF were found significantly higher during the cold period.…”

“…Thus, according to Figure 8, the most abundant congener was PCB118, accounting for 45.9-46.1% of the relative abundance followed by PCB105 (13.7-15.2%), PCB167 (8.1-16.7%), and PCB77 (5.1-5.7%). The outcome from our study matches the profile from other studies in both gas and particulate phase [6,20,23,72], except for PCB167, reinforcing the conclusion that the dlPCBs' profile does not depend on the sampling location. In regard to particle-bound dlPCBs, no seasonal pattern was observed during the sampling campaign (Table 3), with concentrations and WHOTEQ 2005 values for each congener (Figure 6) being quite similar between the cold and warm periods.…”

“…The PCDD/F and dlPCB results obtained in this study are summarized in Tables 3 and 4 [20], and in PM10 from Rome with 5.43-734 fg WHOTEQ 98 m −3 [54]. Higher concentrations were also presented in many industrial sites worldwide (Table 5), and our results were classified among the lowest in global literature.…”

Atmospheric Concentrations and Health Implications of PAHs, PCBs and PCDD/Fs in the Vicinity of a Heavily Industrialized Site in Greece

Background: Thriassion Plain is considered the most industrialized area in Greece and thus a place where emissions of pollutants are expected to be elevated, leading to the degradation of air quality. Methods: Simultaneous determination of polycyclic aromatic hydrocarbons (PAHs), polychlorinated dibenzo-p-dioxins/dibenzofurans (PCDD/Fs), and polychlorinated biphenyls (PCBs) was performed in PM10 samples. SPSS statistical package was employed for statistical analysis and source apportionment purposes. Cancer risk was estimated from total persistent organic pollutants’ (POPs) dataset according to the available literature. Results: POPs concentrations in particulate matter were measured in similar levels compared to other studies in Greece and worldwide, with mean concentrations of ΣPAHs, ΣPCDD/Fs, dioxin like PCBs, and indicator PCBs being 7.07 ng m−3, 479 fg m−3, 1634 fg m−3, and 18.1 pg m−3, respectively. Seasonal variations were observed only for PAHS with higher concentrations during cold period. MDRs, D/F ratios, and principal component analysis (PCA) highlighted combustions as the main source of POPs’ emissions. Estimation of particles’ carcinogenic and mutagenic potential indicates the increased toxicity of PM10 during cold periods, and cancer risk assessment concludes that 3 to 4 people out of 100,000 may suffer from cancer due to POPs’ inhalation. Conclusions: Increased cancer risk for citizens leads to the necessity of chronic POPs’ monitoring in Thriassion Plain, and such strategies have to be a priority for Greek environmental authorities.

Assessment of Air Pollution with Polychlorinated Dibenzodioxins (PCDDs) and Polychlorinated Dibenzofuranes (PCDFs) in Lithuania

et al. 2020

Polychlorinated dibenzodioxins and polychlorinated dibenzofurans (PCDD/F) are highly bioavailable in humans, either through direct inhalation or indirectly by trophic transfer from contaminated food or water. The main sources of pollution with PCDD/F include industrial and non-industrial combustion sources, like domestic contaminated wood burning, house fires, burning of leaves from trees, etc. When looking for alternative energy sources and reduced energy costs, solid waste incineration plants are intended to be built in the vicinity of urbanized areas, and thus, the need emerges for examination and prediction of to what extent the solid waste incineration plants might affect the surrounding ecosystem, air pollution, and human health. Polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs) (or simply PCDD/F congeners) belong to the group of semi-volatile organic compounds with environmental stability and long-range transfer in the ambient air. Dioxin isomers are highly toxic and may have carcinogenic and mutagenic effects in humans. PCDD/F is detected in air, water, sediment, plants and animals. PCDD/F is generally distributed in the particulate phase in ambient air. For solid waste incineration plant emissions, the distribution of PCDD/F particles into particles with a diameter of <10 μm is more than 81% of the total particulate matter, and more than 54% of the PCDD/F is distributed into particles with a diameter of <2.5 μm. The aim of this study is to investigate the sources of PCDD/F, emissions and potential hazards, i.e., a toxic equivalent in Lithuania. The measurements were performed in two largest cities of Lithuania Vilnius and Kaunas, where the level of PCDD/F discovered was from 0.015 to 0.52 pg/m3 and from 0.02 to 0.05 pg/m3, respectively. The sites for the monitoring were selected based on their proximity to the locations of the planned cogeneration power plants in these cities.
