What is known, however, is that trophoblasts, a type of fetal cell exerting vital immunologic functions to maintain a successful pregnancy, are usually involved in the pathogenic mechanism of pregnancy complications. Objective To study the effect of SO2 derivatives (bisulfite and sulfite, 1:3 M/...
Laboratory simulation studies have found that it is difficult for SO2 to convert to sulfate on the surface of mineral dust other than Fe2O3 and MgO, but the coexistence of O3 can convert SO2 to sulfate22. As a kind of secondary pollutant, the atmospheric concentration of O3 is closely ...
In addition, pure SO2 was injected with either primary or secondary combustion air up to a maximum level of 1% in the flue gas. A clear relationship between SO2 and other pollutant emissions was noted in this study regardless of coal type, limestone addition, or SO2 injection location. The ...
Sulfur dioxide (SO2) emitted from the combustion of fossil flues is a major atmospheric pollutant that seriously threatens the environment and human health. The traditional methods for the removal and recovery of SO2 are irreversible and can result in secondary pollution or suffer from solvent loss....
Sulfur dioxide (SO2) in the planetary boundary layer (PBL) as a kind of gaseous pollutant has a strong effect regarding atmospheric environment, air quality, and climate change. As one of the most po...
A marked reduction of SO2 and NOx emission levels can be achieved by means of process-control methods. Sulfur capture by limestone additions into the bed can be optimized by the selection of appropriate process conditions, e.g., bed temperature and the ratio of primary to secondary air. Effect...
University, near the main roads on both sides to carry out environmental monitoring of air distribution on the basis of preliminary find out its ambient air quality status, draw more than one point of the trunk roads on both sides of a number of pollution indicators in national secondary ...
The invention realizes the electrostatic spraying, SO2 absorption and product oxidization in one reactor, not only realizes high efficiency for removing SO2 pollutant, but also effectively prevents secondary pollution.潘卫国王文欢豆斌林强金
Moreover, such technology can be applied at atmospheric pressure and room temperature without any obvious secondary pollution [23]. Dielectric Barrier Discharge (DBD) is a kind of NTP reactor. It can generate electrical discharge when the two electrodes are imposed by high voltage alternating ...
Method name: A new method for estimation of industries development on air pollutant emission by modeling. Name and reference of original method: Air pollution modeling Resource availability: NA Method details There is a well-established correlation between economic progress and environmental contamination ...
