“…The deposition velocity (V d ) of the measured ions can be used as a measure of mass transfer onto the receiving surface (Hosker and Lindberg, 1982) and is calculated according to the formula V d = F/C. In the present study DD velocities of major ions are determined by taking ratio of the fluxes of major ions (F) to the simultaneously measured air concentrations (C) of the respective ions.…”

Wet deposition (WD) and Dry deposition (DD) samples were collected during a period of 4 year (2006 to 2009) + is higher (64-80%) than the DD flux at three locations and slightly lower (48%) at a high altitude location. In case of sea salt (Na and Cl), WD fluxes were higher (63-90%) than the DD fluxes at all the four locations. The dominant ion in DD was NO 3 − at Pashan (semi-urban) and Sinhagad (high altitude), Ca 2+ at Swargate (traffic junction) and SO 4 2− at Bhosari (industrial). The difference in deposition fluxes between the four sites was attributed to the effect of the local sources. Deposition velocities of SO 4 2− and NH 4 + were < 1 cm/s while Ca 2+ , Mg 2+ , Na + , K + , NO 3 − , and Cl − exhibited deposition velocities ≥ 1 cm/s. At one of the sites Pashan, where the earlier data is available; DD rates showed increase in all the chemical components, except for NH 4 + after a period of about 2 decades.

“…The particles can enter into soil as dry, humid or occult deposits and can undermine its physico-chemical properties. The deposit of the particles is complex and it is controlled by the atmospheric stability, the roughness of the surfaces as well as the diameter of the particles (Hosker and Lindberg, 1982). Certainly, the dry deposit of the atmospheric particles is a longer process than the two other types of deposits (Hicks, 1986).…”

ABSTRACT:To evaluate the impact of the cement's dust emitted by the eastern Moroccan cement factory (Oujda Holcim) and deposited on the soil of the Ain Lahjar commune, 58 samples of soil were collected around the factory on a radius of 3 km approximately. The physicochemical analyses of the upper 3 cm of the soil surface samples correspond to the pH, electrical conductivity, the chlorides and the oxides of Ca, Al, Fe, K, Mn, S and Si which were analyzed by the fluorescence of X-rays. The preliminary results demonstrate that this dust are especially basic and contain a high free lime (43% CaO). The principal component analysis (applied on the 58 samples of soil) allows deducting that the free lime and the sulfur oxide are the tracer elements of this form of pollution. Furthermore, the spatial projection of the factor scores of the principal component analysis using the geographical information system permits to determine the spatial distribution of more polluted areas of soils as well as to estimate their surface (63.3% of the survey zone).

“…is the conductance of the cuticle for the direct transcuticular uptake of HNO3 (assumed to be a constant). While the equation for stomatal deposition of HNO3 based on water vapour flux through leaves has been widely applied to trace gas deposition processes (O'Dell, Taheri & Kabel, 1977;Hosker & Lindberg, 1982;Fowler, 1984;Taylor, Hanson & Baldocchi, 1988), the analogous equation for direct transcuticular uptake is chosen for simplicity because the exact mechanism for such a transfer is not yet known. Accumulation of surface sorbed HNO3 CXorp) ^nd subsequent post-exposure cuticular uptake CX.,,) expressed in nmol s"^ m"^ of leaf area are calculated as follows:…”

SUMMARYNitric acid vapour enriched with "N (H^'^NOj) was volatilized into the cuvette of an open-flow gas exchange system containing red maple (Acer rubrum L.), white oak (Quercus alba L.), or loblolly pine {Pinus taeda L.) seedling shoots to facilitate direct measurements of total foliar deposition, and subsequent assessments of the rate of HNO3 movement across the cuticle (transcuticular uptake). Total H^'^NOj vapour deposition to foliar surfaces ranged from < 5 to 27 nmol m'-s \ the variability being largely accounted for by differences in HNO,, concentrations and leaf conductance. Mean whole-leaf conductance to HNO,, ranged between 09 and 34 mm s ' for hardwoods and between 6 and 34 mm s"' for loblolly pine. Of the total H^'^NO,^ vapour deposited to leaves, an average of 39 to 48 % was immediately ' bound' into hardwood foliage whereas only 3 "o was bound to loblolly pine needles. This implies that rain events might extract greater amounts of HNO.^-derived nitrate in throughfall from conifer canopies as compared to hardwood canopies. Post-exposure H^'NOj uptake rates across the leaf cuticle increased with surface nitrate concentrations, but were 1 to 2 orders of magnitude lower (006 to 0-24 nmol m ' s~^) than total HNO^ deposition during exposures.A generalized leaf-level model of HNO3 deposition to foliage capable of simulating deposition pathways to sorption sites on the leaf surface, and to the metabolically active leaf interior via transcuticular or stomatal pathways is formulated and suggested for use m planning future work on HNO.j deposition.
