Ab initioPOL–CI calculations, augmented by a dispersion term, are used to predict the potential energy surface for the reaction Cl+HCl. The saddle point i... BC Garrett,DG Truhlar,AF Wagner,... - 《Journal of Chemical Physics》
The outer layers of the mammalian epidermis protect the organism from water loss and external injury. The bather as visualized with tracers has been shown to develop initially in the stratum granulosum concurrent with the intercellular deposition of extruded lamellar-body contents. This lamellar ...
Daily fine particulate (PM2.5) samples were collected in Chengdu from April 2009 to February 2010 to investigate their chemical profiles during dust storms (DSs) and several types of pollution events, including haze (HDs), biomass burning (BBs), and fireworks displays (FDs). The highest PM...
InMAP calculates the annual average concentration of pollutants by using equations that account for the travel and deposition of air pollution (advection, mixing, chemical reactions, and deposition equations) across a variable spatial grid. Advection is the transport of air pollution from the wind. Mi...
Although traffic, power plants, and industrial and chemical plants produce the majority of Earth's outdoor air pollution, many other factors contribute to the problem. The causes of indoor air pollution are very different. In many parts of the world, people still rely on burning solid fuels (...
"Severe air pollution events still happen in over half of the cities across the country," it said. The ministry noted increasing ozone density as another prominent problem for air pollution control. "Ozone pollution has become an increasingly prominent problem, especially in summer," it said. ...
Acid rain is also a form of pollution induced by pollutants emitted by combustion processes of fuels, SOx and NOx. Arrived in the atmosphere, sulphur and nitrogen oxides react with oxygen, water vapors and other substances forming acid compounds, such as dilute solutions of H2SO4, HNO3 and th...
CSL researchers also found that submicron aerosol composition during pollution events is dominated by ammonium nitrate, which is formed from the reaction of ammonia (mostly from agriculture) and nitric acid (mostly from urban emissions). Furthermore, nighttime and early morning chemistry in the upper...
The pollutants formed by the intermingling and reaction of primary pollutants are known as secondary pollutants. Smog, formed by the intermingling of smoke and fog, is a secondary pollutant. Also Read: Water Pollution Causes of Air Pollution Following are the important causes of air pollution: Bu...
