MONTREAL, Dec. 16 /PRNewswire/ - Odotech Inc., winner of several prestigious innovation and Cleantech awards, has added another technology breakthrough to its list of firsts. Its new OdoSulf system measures H2S down to 2 ppb, close to the odor perception threshold. Using real-time automated dispersion modelling it can display on the plant operator's screen the H2S dispersion plume (impact), while archiving all H2S and weather data. Hydrogen sulfide is toxic at high concentrations. At...

DALLAS, June 15 /PRNewswire/ -- RealTime Laboratories, LLC announced today significant new findings regarding pervasive bacterial presence unique to contaminated drywall. RealTime has identified specific bacteria found only in symptomatic drywall and not in normal domestic drywall that are viable, pervasive and produce hydrogen sulfide and reduced sulfur gases under conditions similar to those found in residences. Cultures developed by RealTime using symptomatic contaminated drywall...

SEATTLE, June 11 /PRNewswire/ -- How is it that some people who apparently freeze to death, with no heart rate or respiration for extended periods, can be brought back to life with no long-term negative health consequences? New findings from the laboratory of cell biologist Mark B. Roth, Ph.D., of Fred Hutchinson Cancer Research Center, may help explain the mechanics behind this widely documented phenomenon. Reporting online ahead of the July 1 print issue of Molecular Biology of the Cell,...

Stratified marine basin sheds new light on early animal evolution, UC Riverside scientists say A research team led by biogeochemists at the University of California, Riverside has developed a detailed and dynamic three-dimensional model of Earth's early ocean chemistry that can significantly advance our understanding of how early animal life evolved on the planet. Working on rock samples from the Doushantuo Formation of South China, one of the oldest fossil beds and long viewed by...

NEEDHAM, Mass., Nov. 24 /PRNewswire/ -- Environmental Health & Engineering Inc. (EH&E), a leading Massachusetts-based engineering consulting firm, has completed a major indoor air quality study for the U.S. government which found a strong association between the presence of Chinese drywall, low level concentrations of hydrogen sulfide, and corrosion of metals in homes. The drywall issue has affected thousands of homes in the United States for more than two years. The five-month...

A new study showed a significant link between indoor pollution in homes with drywall imported from China, leading U.S. officials to take a deeper look at the affect that the product has on health. According to the Consumer Product Safety Commission (CPSC), it will be heading up an investigation into finding the origin and distribution of the drywall as well as the connection between the drywall and the reported health symptoms, and electrical and fire safety issues that some home owners...

Even low concentrations of oxygen can have profound effects on ocean chemistry Scientists widely accept that around 2.4 billion years ago, the Earth's atmosphere underwent a dramatic change when oxygen levels rose sharply. Called the "Great Oxidation Event" (GOE), the oxygen spike marks an important milestone in Earth's history, the transformation from an oxygen-poor atmosphere to an oxygen-rich one, paving the way for complex life to develop. Two questions that remain unresolved in studies...

A UC Riverside-led study reports on the effects of biological oxygen production nearly 100 million years before oxygen accumulated in the atmosphere Scientists widely accept that around 2.4 billion years ago, the Earth's atmosphere underwent a dramatic change when oxygen levels rose sharply. Called the "Great Oxidation Event" (GOE), the oxygen spike marks an important milestone in Earth's history, the transformation from an oxygen-poor atmosphere to an oxygen-rich one paving the way for...

Garlic provides cardioprotection, but freshly crushed garlic has more potent heart-healthy effects, U.S. researchers found. Researchers at the University of Connecticut School of Medicine in Farmington also challenge the widespread belief that most of garlic's benefits are due to its rich array of antioxidants. Dipak K. Das and colleagues point out that raw, crushed garlic generates hydrogen sulfide through a chemical reaction. Although best known as the stuff that gives rotten eggs their...

Sulfur (or Sulphur; see spelling below) is the chemical element in the periodic table that has the symbol S and atomic number 16. It is an abundant, tasteless, odorless, multivalent non-metal. Sulfur, in its native form, is a yellow crystaline solid. In nature, it can be found as the pure element or as sulfide and sulfate minerals. It is an essential element for life and is found in several amino acids. Its commercial uses are primarily in fertilizers but it is also widely used in gunpowder,...
