Polycyclic aromatic hydrocarbons, polychlorinated biphenyls, and chlorinated pesticides in background air in central Europe – investigating parameters affecting wet scavenging of polycyclic aromatic hydrocarbons
Concentrations of polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs), and chlorinated pesticides (CPs) were measured in air and precipitation at a background site in central Europe. ∑ PAH concentrations in air and rainwater ranged from 0.7 to 327.9 ng m<sup>−3<...

| description | Concentrations of polycyclic aromatic hydrocarbons (PAHs), polychlorinated
biphenyls (PCBs), and chlorinated pesticides (CPs) were measured in air and
precipitation at a background site in central Europe. ∑ PAH
concentrations in air and rainwater ranged from 0.7 to 327.9 ng m<sup>−3</sup> and
below limit of quantification (< LOQ) to 2.1 × 10<sup>3</sup> ng L<sup>−1</sup>. The concentrations of PCBs and CPs in rainwater were
< LOQ. ∑ PCB and ∑ CP concentrations in air ranged from
< LOQ to 44.6 and < LOQ to 351.7 pg m<sup>−3</sup>, respectively.
The potential relationships between PAH wet scavenging and particulate
matter and rainwater properties were investigated. The concentrations of
ionic species in particulate matter and rainwater were significantly
correlated, highlighting the importance of particle scavenging process.
Overall, higher scavenging efficiencies were found for relatively less
volatile PAHs, underlining the effect of analyte gas-particle partitioning
on scavenging process. The particulate matter removal by rain, and
consequently PAH wet scavenging, was more effective when the concentrations
of ionic species were high. In addition, the elemental and organic carbon
contents of the particulate matter were found to influence the PAH
scavenging. |
