Sulfur dioxide emissions from Peruvian copper …

[1] We report the first daily observations of sulfur dioxide (SO 2) emissions from copper smelters by a satellite-borne sensor - the Ozone Monitoring Instrument (OMI) on NASA''s EOS/Aura spacecraft. Emissions from two Peruvian smelters (La Oroya and Ilo) were detected in up to 80% of OMI overpasses between Septeer 2004 and June 2005.

Molecular Diagnosis of Brettanomyces bruxellensis’ …

The yeast species Brettanomyces bruxellensis is associated with important economic losses due to red wine spoilage. The most common method to prevent and/or control B. bruxellensis spoilage in winemaking is the addition of sulfur dioxide into must and wine. However, recently, it was reported that some B. bruxellensis strains could be tolerant to commonly used doses of SO2.

Herbal Medicine Quality Assurance | KPC Products, Inc.

Sulfur dioxide bleaches the herbs Dioscorea (shan yao), Pueraria Root (ge gen) and dried ginger (gan jiang). KP opposes the use of sulfur dioxide in herbs because of the serious effects on the nature of Chinese herbs. Sulfur dioxide causes high sugar-content herbs, such as Cibotium (gou ji), to become noticeably more acidic.

Simplified Method for Free SO2 Measurement Using …

The classic Monier–Williams method for free sulfur dioxide (SO2) measurement in wines was modified using inexpensive SO2 detection tubes developed for the mining industry. An acidified wine sample was treated with an antacid tablet to evolve CO2 in situ and the gas flow directed to a commercial SO2 detection tube. The length of tube that changed color was proportional to the original free
