Polluting characteristics, sources, cancer risk, and cellular toxicity of PAHs bound in atmospheric particulates sampled from an economic transformation demonstration area of Dongguan in the Pearl River Delta, China

Probing the occurrence, sources and cancer risk assessment of polycyclic aromatic hydrocarbons in PM2.5 in a humid metropolitan city in China

“…The ILCR in Chongqing is higher than those from Hefei (children: 0.07 × 10 −6 , adolescents: 0.01 × 10 −6 , and adults: 0.20 × 10 −6 ) 59 and Guangzhou (children: 0.06 × 10 −6 , adolescents: 0.06 × 10 −6 , and adults: 0.02 × 10 −6 ), 60 comparable to that in Nanjing (children: 0.26 × 10 −6 and adults: 0.41 × 10 −6 ), 61 but much lower than that in Dongguan (children: 3.81 × 10 −6 and adults: 4.83 × 10 −6 ). 62 Detailed comparisons with other cities are summarized in Table S9 †…”

“…They constitute a very low fraction (i.e., usually lower than 1%) of the mass of particulate matter with an aerodynamic diameter less than or equal to 2.5 mm (PM 2.5 ). 1,2 However, PAHs remain a focus for atmospheric researchers due to their carcinogenic and mutagenic effects on human health, and their multiple and various emission sources. PAHs are mostly from anthropogenic sources, such as crude and rened petroleum (i.e., petrogenic PAHs) and incomplete combustion of fossil fuel (i.e., pyrogenic PAHs).…”

FMS-TTP-SPE Ön Hazırlık Sistemi Kullanılarak Polisiklik Aromatik Hidrokarbonların Analizi için Yöntem Geliştirilmesi: Yöntemin Isparta İli Gölcük Gölünden Alınan Su Numunelerine Uygulanması

“…Sularda bulunan PAH konsantrasyonları, PAH'ların lipofilik özellik göstermelerinden dolayı çok düşüktür (ng mL −1 (ppb) seviyelerinde veya daha düşük) [10,11]. Kalıcı, toksik, mutajenik ve kanserojen özelliklerinden dolayı çevredeki PAH riski ile başa çıkmak önemlidir [12]. Yaygın olan PAH'lardan on altı tanesi, asenaften, asenafetilen, antrasen, benz[a]antrasen, benzo[a]piren, benzo[b]floranten, benzo[ghi]perilen, benzo[k]floranten, krizen, dibenz[a,h]antrasen, floranten, floren, indeno [1,2,3-cd]piren, naftalin, fenantren ve piren US EPA tarafından öncelikli kirleticiler olarak listelenmişlerdir.…”
