Primary Product Distribution from the Reaction of Hydroxyl Radicals with Toluene at ppb NOX Mixing Ratios
Journal of Atmospheric Chemistry - Tập 31 - Trang 349-350 - 1998
When this paper was first published Figure 5 was incorrect. The publisher regrets this oversight. The complete page with correct figure and original pagination is printed overleaf.
Characteristics of reactive nitrogen compounds and other relevant trace gases in the atmosphere at urban and rural areas of Korea during May–June, 2004
Journal of Atmospheric Chemistry - Tập 58 - Trang 203-218 - 2007
This study examines the general characteristics of reactive nitrogen oxides (NOy) at urban and rural sites in terms of measurement- and modeling-based analyses. In this field study, NOx at urban and rural sites were 92 and 89% of NOy on average, respectively. HONO levels (e.g., 1.8 ppbv) at the urban site were significantly higher than those at the rural site by a factor of 4.5. HONO concentration......
Rainwater Chemistry and Wet Deposition over the Equatorial Forested Ecosystem of Zoétélé (Cameroon)
Journal of Atmospheric Chemistry - Tập 46 - Trang 173-198 - 2003
Within the framework of IDAF (IGAC DEBITS AFRICA: International GlobalAtmospheric Chemistry/DEposition of Biogeochemically Important TraceSpecies/Africa) network, data analysis is realised on precipitation chemical composition collected in Zoétélé, in Southern Cameroon. This station, located atabout 200 km from the Atlantic Ocean, is representative of a so-called `Evergreen Equatorial Forest' ecos......
Model for estimating activity coefficients in binary and ternary ionic surfactant solutions
Journal of Atmospheric Chemistry - Tập 77 - Trang 141-168 - 2020
We introduce the CMC based Ionic Surfactant Activity model (CISA) to calculate activity coefficients in ternary aqueous solutions of an ionic surfactant and an inorganic salt. The surfactant can be either anionic or cationic and in the present development, the surfactant and inorganic salts share a common counterion. CISA incorporates micellization into the Pitzer–Debye–Hückel (PDH) framework for ......
On the scavenging of SO2 by cloud and raindrops: I. A theoretical study of SO2 absorption and desorption for water drops in air
Journal of Atmospheric Chemistry - Tập 1 - Trang 269-289 - 1983
An extention of our previous theory for trace gas absorption into freely-falling cloud and raindrops is presented. This theory describes the convective diffusion of a trace gas through air and into a water drop with internal circulation, the drop falling at its terminal velocity. Using flow fields for the circulating water inside and for the moving air outside the drop, obtained by numerical solut......
Reduction of Multiphase Atmospheric Chemistry
Journal of Atmospheric Chemistry - Tập 46 - Trang 131-157 - 2003
The aim of this article is to investigate the dynamical behaviour ofmultiphase atmospheric chemical mechanisms. Reducing procedures areapplied to a multiphase chemical box model including gas-phasereactions, aqueous-phase reactions and interfacial mass transfer. The lumping of species is computed in an automatic wayusing an efficient algorithm (apla). The computed lumped species arerelated to the ......
Bioaccumulation of Cobalt in Parmelia sulcata
Journal of Atmospheric Chemistry - Tập 49 Số 1 - Trang 67-82 - 2004
Six locations across mainland Portugal were selected for exposing Parmelia sulcata, for a one-year period (8 months for one site), with simultaneous measurement of total (dry + wet) deposition (one-month periods). The exposed lichens and the total (dry + wet) deposition were analysed for cobalt contents by INAA (instrumental neutron activation analysis) and ICP-MS (inductively coupled plasma mass ......
The Mechanism of Reactive NO3 Uptake on Dry NaX (X=Cl, Br)
Journal of Atmospheric Chemistry - Tập 34 - Trang 119-135 - 1999
A simple kinetic mechanism of nitrate radicals uptake on dry sea-salt NaCl, NaBr surfaces is proposed. The mechanism includes adsorption/desorption equilibrium and unimolecular decomposition of the adsorbed complex: NO3(g) + NaX(s) ↔ (NO3-NaX)(s); (NO3-NaX)(s) → NaNO3 + X(s) Two techniques were used: the matrix isolation ESR and mass spectrometry. The uptake coefficient (γ) is found to be dependen......
Second-order closure study of the covariance between chemically reactive species in the surface layer
Journal of Atmospheric Chemistry - Tập 16 - Trang 145-155 - 1993
A second-order modelling technique is used to investigate the influence of turbulence on chemical reactions. The covariance and variance equations for the NO-O3-NO2 system are developed as a function of the ratio of the timescale of turbulence (τ
t
) and the timescale of chemistry (τCh): the first Damköhler number (τ
t
/τCh). Spec......
