Nitro - polycyclic aromatic hydrocarbons - gas - particle partitioning , mass size
14 Nitro-polycyclic aromatic hydrocarbons (NPAH) are ubiquitous in polluted air but little is 15 known about their abundance in background air. NPAHs were studied at one marine and one 16 continental background site i.e., a coastal site in the southern Aegean Sea (summer 2012) and 17 a site in the central Great Hungarian Plain (summer 2013), together with the parent 18 compounds, PAHs. A Lagran...
متن کاملAir–sea exchange and gas–particle partitioning of polycyclic aromatic hydrocarbons in the Mediterranean
Polycyclic aromatic hydrocarbon (PAH) concentration in air of the central and eastern Mediterranean in summer 2010 was 1.45 (0.30–3.25) ng m−3 (sum of 25 PAHs), with 8 (1–17) % in the particulate phase, almost exclusively associated with particles < 0.25 μm. The total deposition flux of particulate PAHs was 0.3–0.5 μ g m−2 yr−1. The diffusive air–sea exchange fluxes of fluoranthene and pyrene w...
متن کاملGas/particle partitioning and global distribution of polycyclic aromatic hydrocarbons--a modelling approach.
The global atmospheric distribution and long-range transport (LRT) potential of three polycyclic aromatic hydrocarbons (PAH) - anthracene, fluoranthene and benzo[a]pyrene - are studied. The model used is a global aerosol-chemistry-transport-model, which is based on an atmospheric general circulation model. The model includes an in-built dynamic aerosol model coupled to two-dimensional surface c...
متن کاملPartitioning of crude oil polycyclic aromatic hydrocarbons in aquatic systems.
This paper investigates the hypothesis that observed polycyclic aromatic hydrocarbon (PAH) concentrations in an aqueous system are equal to the sum of the organic phase and soluble phase molar concentrations. While the organic phase concentrations are proportional to the PAH mole fraction in the oil, the soluble phase molar concentrations are estimated using Raoult's law. A batch laboratory mix...
متن کاملPolycyclic Aromatic Hydrocarbons in the Atmosphere of Two Subtropical Cities in Southeast China: Seasonal Variation and Gas/Particle Partitioning
Eighteen polycyclic aromatic hydrocarbons (PAHs) were measured in the gas and particle phase from four sites in two cities, Quanzhou and Xiamen, in Southeast China during January (winter), March (spring), August (summer) and November (fall) 2010. The total concentration in the gas phase ranged from 10.7 ± 2.4 to 507.8 ± 57.0 ng/m, while in the particle phase between 1.4 ± 0.5 and 46.5 ± 19.1 ng...
