Abstract/OtherAbstract:
The wet deposition for particulate matter (PM) and polycyclic aromatic hydrocarbons (PAHs) was modelled from the consecutive measurements of atmospheric concentration and wet deposition for particulate matter and PAHs in Higashi-Hiroshima city, Japan. In order to estimate the model in detail, the wet deposition was classified with that from gaseous and PM phase. The gaseous PAHs assumed to be dissolved into raindrops according to Henry's constant, and the PAHs attached on atmospheric PM were assumed to be trapped with PM. The PM was classified with coarse (>7 μm) and fine (0.6-7 μm) PM for the calculation of trap. PM and PAHs depositions estimated with the wet deposition model were compared with measured data. The ratios of the measured to the estimated values of PM and PAHs gave close agreement with measurements (0.41-4.29 (1.35: average) for PM and (0.32-3.83 (1.42)) for PAHs) regardless of precipitation. The depositions of PAHs of liquid and particulate phase were on the other hand significantly different from those from gaseous and PM phases respectively. From those differences, the transfer from particulate to liquid phase was suggested to occur during the precipitation.
