由于我国的能源结构以煤炭为主，煤炭燃烧产生的SO2污染是我国面临的重大环境问题之一。除了SO2本身对人体健康有严重的影响，其通过气粒转化形成的二次气溶胶粒子会加剧灰霾的发生和发展。在“十一五”之后，SO2污染物总量减排成为我国的一项重要任务。许多研究工作都表明，我国SO2的排放量呈现显著的下降趋势。但是，仍有一些科学问题尚未弄清：(1) SO2是单调持续下降，还是存在一些复杂波动过程？(2) 不同...
Geoengineering by stratospheric SO2 injection: results from the Met Office HadGEM2 climate model and comparison with the Goddard Institute for Space Studies ModelE

In anthropogenically influenced atmospheres, sulphur dioxide (SO2) is the main precursor of gaseous sulphuric acid (H2SO4), which in turn is a main precursor for atmospheric particle nucleation. As a ...
East Asian SO2 pollution plume over Europe – Part 1: Airborne trace gas measurements and source identification by particle dispersion model simulations

A large SO2-rich pollution plume of East Asian origin was detected by aircraft based CIMS (Chemical Ionization Mass Spectrometry) measurements at 3–7.5 km altitude over the North Atlantic. The measure...
Oxidation of SO2 by H2O2 on ice surfaces at 228 K: a sink for SO2 in ice clouds

2009/3/12
The heterogeneous reaction SO2 + H2O2 H2SO4 on ice at 228 K has been studied in a low temperature coated-wall flow tube. With H2O2 in excess of SO2, the loss of SO2 on an ice surface is time depende...
