Amaç & Hipotez:Air samples were collected using polyurethane foam passive samplers from 26 air-monitoring stations located inthe Pearl River Delta, China and two in Shaoguan City in Guangdong Province in 2015 to investigate the occurrenceand distribution of priority polycyclic aromatic hydrocarbons (PAHs).
📊
Temel Bulgular & Veri:Sixteen PAHs were identified and15 of them (except for naphthalene) were quantified at a total concentration (∑15PAHs) that varied from3.56 ng/m3 to 37.2 ng/m3 (average value 19.8 ± 9.69 ng/m3).

Özet

Air samples were collected using polyurethane foam passive samplers from 26 air-monitoring stations located inthe Pearl River Delta, China and two in Shaoguan City in Guangdong Province in 2015 to investigate the occurrenceand distribution of priority polycyclic aromatic hydrocarbons (PAHs). Sixteen PAHs were identified and15 of them (except for naphthalene) were quantified at a total concentration (∑15PAHs) that varied from3.56 ng/m3 to 37.2 ng/m3 (average value 19.8 ± 9.69 ng/m3). The results indicated that PAHs with 3–4 benzenerings accounted for approximately 80% of all PAH compounds, among which phenanthrene and fluoranthenewere the predominant components. Diagnostic parameters suggested that the possible sources of PAHsin the Delta region were mixed of petrogenic and pyrogenic sources from fuel/biomass/coal combustion. Basedon the measured PAHs concentrations, the Carcinogenic Potency Risk (BaPeq) and Inhalation Cancer Risk (ICR)were assessed, and indicated that two air samples from Guangzhou and one from Foshan exceeded the BaPeqlimit (1 ng/m3), whereas all samples from the 28 sampling locations exceeded the health-based guideline concentrationfor ICR. The results of this research suggest that a potential human health risk exists from PAHs in thestudy area via the respiration and inhalation pathway.
