“…They estimated dry deposition of about 2 ug/m2/y as particulate Se, with wet deposition perhaps two orders of magnitude greater. Their estimate of the dry deposition velocity of particulate Se (0.07 mm/s) is much smaller than our estimates based solely on particle size and those of Wu et al (1994).…”

“…In Seoul, six components accounting for approximately 91.7% of the total variability were identified. The first component (44.4% of the total variance) with the high loadings of several elements (V, Pb, Zn, K, and S) suggest contributions from such sources as oil combustion, incineration, and motor vehicles (e.g., Wu et al, 1994). It may also be related to the re-suspension of soil dust, secondary aerosol, and marine aerosol.…”

In the present study, the distribution patterns of various metals were analyzed and compared using PM samples collected concurrently from three monitoring sites located in Korea (Seoul, Busan, and Jeju island) in December 2002. As these sites can represent metal pollution with different degrees of anthropogenic activities, their concentration levels were distinguished in a systematic manner in the order of Jeju, Busan, and Seoul. By comparing the present data sets with those measured previously from other locations in Korea and around the world, we attempted to diagnose the general status of elemental pollution on the Korean peninsula. Through an application of different statistical approaches, the major processes controlling elemental levels were assessed for each of the three study sites. The results indicated the importance of both crustal and anthropogenic sources in all sites with their relative roles varying significantly from each other. The results of the metal analysis data, when examined in relation to back trajectory analysis, confirmed that their concentration changes are affected quite sensitively with air mass movement patterns. The overall results of this study consistently indicated the contribution of a strong anthropogenic source area (e.g., China) to the observed metal concentration levels in the study area, but the strengths of such signals vary considerably across the Korean peninsula.

“…The effect of dust could be physical through deposition of particles on the surfaces of leaves, with adverse effect on the growth of plants (Iqbal and Shafig 2001) and variations of stomata activities (opening and closing mechanisms) (Krajickova and Mejstrik 1984), and it could be chemical through the nutrient absorption from the soil and modifications of cycling of nutrients necessary for plants and their availability for uptake by plants (Stoorvogel et al 1997;Kurtz et al 2001;Reynolds et al 2001). There has also been a focus on the seasonal variations of chemical composition of dust (Zhong et al 1994;Norra and Stüben 2004;Elemide and Abulude 2007).…”

The present study determines the source of dust particles and investigates their impact on the chemical compositions of plants and soils around a cement factory in Oman within a radius of 10 km of this disturbed ecosystem. A total number of nine samples of the species of plants (Rhazya stricta), nine samples of soils, and nine samples of dust were collected and analyzed for major ions and trace elements including rare earth elements (REEs). Principal component analysis applied to the major and trace element concentrations in the dust indicated the input of at least two sources to the dust in the study area: ophiolites and cement. The REE distribution in the plants and soils revealed that the most available elements to plants originated dominantly from ophiolites rather than from cement. The contribution of cement industry is significant only in the zone located at about 0.500 to 2 km around the cement factory, whereas the contribution of ophiolites increases with distance from the cement factory.
