Oxidation kinetics of Fe(II) in a eutrophic Swiss lake

Article Abstract:

An automated flow injection analysis system was employed in determining the oxidation rate of ferrous iron in lake Greifen, Switzerland. The pH levels for unfiltered samples were shown to be between 6.8 and 8.3 and showed traces of carbon dioxide and synthetic air. Levels of pH 6.8 and pH 7.3 may be accounted for by natural phenomena which speed up oxidation of ferrous iron. Results also revealed oxidation rates for unfiltered samples to be at 2-2000 nM Fe(II).

Mossbauer study of atmospheric aerosols of Shanghai

Article Abstract:

The concentration of iron and iron compounds in atmosphere of Shanghai City, China, were studied by Mossbauer spectroscopy combined with SPM (scanning proton microprobe). The chemical compositions of iron compounds in aerosols are explored by means of SPM (scanning proton microprobe). Using the results, the chemicals process by which iron oxides are converted to iron sulfate in air are discussed.

Application of a LRT model to acid rain control in China

Article Abstract:

A model of the long-range transport and deposition of sulfur dioxide is used to develop a policy for regional acid rain control in eastern China. Maps of eastern China show sulfur emission sources taken from a Chinese Research Academy of Environmental Sciences database, and policy goals are set for each province.
