“…The exception was site A 10 , which showed significantly higher concentrations in summer than in winter. This trend was consistent with trends observed in many other studies (Ding et al 2013;Gao et al 2014;Li et al 2011;Li et al 2008b;Lohmann and Jones 1998;Raun et al 2005). Min et al (2014) observed the opposite trend for PCDD/F concentrations in 10 cities near Seoul.…”

“…The main contributors to the 2,3,7,8-PCDD/F concentrations in summer were 1,2,3,4,6,7,8-HpCDF; 2,3,7,8-TCDF; and 1,2,3,6,7,8-TCDF, which accounted for 13.6-27.1 % (mean 19.4 %), 4.0-17.6 % (mean 10.8 %), and 7.4-13.0 % (mean 9.8 %) of the total 2,3,7,8-PCDD/F concentrations, respectively. In winter, 1,2,3,4,6,7,8-HpCDF; OCDD; and 2,3,7,8-TCDF dominated the PCDD/F concentration profiles, providing relative contributions of 9.9- (Gao et al 2014;Li et al 2008b;Moussaoui et al 2012;Yu et al 2006). Our results indicated that PCDFs (70.1 % in summer and 72.2 % in winter) were more dominant than PCDDs (29.9 % in summer and 27.8 % in winter).…”

The seasonal and spatial variations, compositional profiles, and possible sources of polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans (PCDD/Fs) in ambient air samples in Shanghai of China were investigated by passive air samplers, and the potential inhalation risks posed by these chemicals were evaluated. The following results were obtained: (1) The World Health Organization (WHO) toxic equivalency (TEQ) values for PCDD/Fs were in the range of 10.8-259 fg m(-3) (mean 63.4 fg m(-3)) in summer and 24.1-154 fg m(-3) (mean 83.4 fg m(-3)) in winter. Atmospheric PCDD/F levels were in the following order: industrial areas > commercial and residential areas > rural areas. (2) 2,3,4,7,8-PeCDF (24 %), 2,3,7,8-TeCDD (16 %), 1,2,3,7,8-PeCDD (13 %), and 2,3,7,8-TeCDF (12 %) were the predominant contributors to the TEQ of PCDD/Fs. (3) There was a slight seasonal trend with higher TEQ values in winter than in summer, which could be related to seasonal variations in the dispersion of PCDD/Fs in ambient air. (4) The children's daily intake was at the lower end of the range for the tolerable daily intake of PCDD/Fs recommended by WHO, which indicates that the inhalation risk of PCDD/Fs for local residents in Shanghai is relatively low.

“…Figure 2 shows the map of the sampling area. Air samples were collected using polyurethane foam (PUF) passive samplers [17][18][19]. The passive sampler consisted of two different sizes of stainless steel bowls (30 and 24 cm) and polyurethane filters (14 cm diameter, 1.35 cm thick, with a surface area of 365 cm 2 and density of 0.030 g/ cm 3 ).…”

Open burning of municipal solid waste (MSW) is a common practice in Nigeria. Emission of compounds of polycyclic aromatic hydrocarbon (PAHs) in ambient air and ash residues from burning of these wastes pose a great danger to the environment. This study investigated the contribution of open burning of MSW to the levels of PAHs in ambient air and ash residues from the burning site. Ash samples were obtained from six sampling locations at a MSW burning site. Polyurethane foam passive samplers were used in collecting ambient air samples. Quantification of PAHs was carried out using GC-MS operated in selected ion monitoring mode. The trend of ambient concentration of PAHs was; ∑ PAHs AS-A (4.023) > AS-B (3.798) > AS-D (3.468) > AS-C (3.288), while average concentration of PAHs in the ash was 6.12 mg/kg. Concentrations of PAHs in ash samples ranged from 5.69-6.34 mg/kg. Principal component analysis (PCA) showed that most of the PAHs in the ambient were from MSW combustion. The results obtained suggest that concerted effort of the government and the relevant stakeholders is required to safeguard the environment and humans from PAH pollution from open burning of MSW.

“…Passive samplers was installed at a minimum of 2 m from the ground in an unobstructed air flow (Schuster et al, 2015). Sampling rate of 3.5 m 3 /day was used to calculate the sampling volume (Shoeib and Harner, 2002;Pozo et al, 2011;Gao et al, 2014). Before air sampling, PUF discs were cleaned by means of soxhlet extraction with toluene as a solvent over first 24 h, then over next 24 h with acetone and the last 8 h in toluene.…”
