Samples of rain, snow, cloud water, aerosols and soil were collected in Colorado to study the mechanisms of acid rain formation. Chemical compositions of various types of samples were analyzed to investigate the stepwise incorporation of impurities into precipitation. Local soil was generally alkaline...
The reaction pathways of acid rain formation from reaction of sulfur dioxide vapor and water vapor on the singlet potential energy surface have been investigated theoretically. The calculated results show that the reactants are initially associated with the adduct SO 2 –H 2 O through a barrier ...
aThere are many sources of chemical hazards including: 有化工危险的许多来源包括:[translate] aEgyptian Trading Directory 埃及贸易的目录[translate] aEffects and mechanisms of the combined pollution of lanthanum and acid rain on the root phenotype of soybean seedlings 正在翻译,请等待...[translate] ...
New particle formation (NPF) in the tropical upper troposphere is a globally important source of atmospheric aerosols1,2,3,4. It is known to occur over the Amazon basin, but the nucleation mechanism and chemical precursors have yet to be identified2. Here we present comprehensive in situ aircr...
Atmospheric aerosol particles are essential for forming clouds and precipitation, thereby influencing Earth’s energy budget, water cycle and climate on regional and global scales. However, the origin of aerosol particles over the Amazon rainforest durin
The interaction between nitrogen monoxide (NO) and organic peroxy radicals (RO2) greatly impacts the formation of highly oxygenated organic molecules (HOM), the key precursors of secondary organic aerosols. It has been thought that HOM production can be
Combustion model was developed by using the principle of chemical-reaction equilibrium. Simulation on the model in order to evaluate the composition of the flue gas was performed by minimization the Gibbs free energy. The results showed that by introduced of biomass in coal combustion can reduce ...
11.Furthermore, ecomat can increase the photo synthetic rate and transpiration rate of Panicled Goldraintree koelreuteha paniculata.此外,生态垫能提高栾树的蒸腾速率和光合速率。 12."Reaction rate: Speed at which a chemical reaction proceeds, in terms of amount of product formed or amount of react...
Such sulfate aerosols influence the surface temperature of the Earth7, acid rain formation8,9, and human health10, playing a key role in environmental chemistry and climate change6,11,12. Therefore, knowing the source(s) of aerosol sulfate and its transport and transformation in the atmosphere ...
Atmospheric nitrous acid (HONO) chemistry is of critical importance to air quality during polluted haze events, especially in China. However, current air quality models (such as WRF-CHEM, WRF-CMAQ, Box-MCM) generally underestimate the concentration of HO
