Development of a Passive Sampling Device Using Polyurethane Foam (PUF) to Measure Polychlorinated Biphenyls (PCBs) and Organochlorine Pesticides (OCPs) near Landfills

Abstract

Recently passive air sampling techniques have been extensively studied and employed in the environmental monitoring of semi volatile chemicals. Polychlorinated biphenyls (PCBs) and organochlorine pesticides (OCPs) samples were collected for 4-week intervals throughout one year from a landfill in Bursa, Turkey. In this study, a passive air sampler (PAS) was designed using polyurethane foam (PUF). The differences between PAS employed in this study and in literature are their shape and ventilation approach. Ventilation pipes, located on top and bottom of the sampler, were employed to prevent precipitation and particles from entering inside the sampler. The sampling rates (R) for PUF was calculated as 7.3 m 3 /d for PCBs and as 3.9 m 3 /d for OCPs. The determined average concentrations were 311 ± 178 pg/m 3 for PCBs, 198 ± 210 pg/m 3 for OCPs.

The first countrywide monitoring of selected POPs: Polychlorinated biphenyls (PCBs), polybrominated diphenyl ethers (PBDEs) and selected organochlorine pesticides (OCPs) in the atmosphere of Turkey

“…The average concentrations of γand δisomers were 7.34±45.7 pg/m 3 and 13.4±86.8 pg/m 3 , respectively (Supplementary Material, Figure S1a). β-HCH was also dominating HCH isomer in Bursa (Esen, 2013;Cindoruk and Tasdemir, 2014) whereas α-HCH was also the dominating isomer in the studies of Aliyeva et al (2012) and Devi et al (2011). The mean α-HCH/γ-HCH ratios for urban and rural sites were 2.26 and 7.68, respectively.…”

“…demolishing sites in the studies conducted in Aliaga (Kaya et al, 2012;Odabasi et al, 2015) and waste landfill in Hamitler (Esen, 2013). Odabasi et al (2016) reported average concentration of Σ PCBs in background and industrial sites in Iskenderun (Turkey) as 180±140 pg/m and 1600±900 pg/m 3 , respectively.…”

Passive air sampling for semi-volatile organic chemicals

“…182 Esen introduced a housing for a PUF-based PAS that seeks to minimise the inuence of wind. 183 A side-by-side comparison with the double-bowl PUF-PAS indicated lower SRs. 184 D.3.2 Activated carbon bre felt sampler.…”

Determination of organochlorine pesticide (OCP) residues in air and pollen samples and pollutant partition between these environments

“…Her iki örnekleme noktasında da α-HCH'ler (%32.3-33.9) ve β-HCH'ler (%24.1-27.1) baskın HCH izomerlerini oluşturmaktadır. Bursa'da yapılan önceki çalışmalarda, muhtemelen kontamine alanlardan atmosferik taşınma ve bitki örtüsünden buharlaşma nedeniyle α-ve β-HCH'lerin baskın HCH izomerleri olduğu rapor edilmiştir [33], [34].…”
