  • Even soil feels the heat

    Twenty years of field studies reveal that as the Earth has gotten warmer, plants and microbes in the soil have given off more carbon dioxide. So-called soil respiration has increased about one-tenth of 1 percent per year since 1989, according to an analysis of past studies in this week's issue of Nature. The scientists also calculated the total amount of carbon dioxide flowing from soils, which ...

  • Tree biodiversity increases release of carbon from soils

    Soils play an important role in the carbon cycle, containing more than two thirds of the total carbon held in terrestrial ecosystems. Concern about climate change and rising CO2 levels is driving research to understand carbon cycling through soils. New research suggests that in tropical regions greater tree diversity increases soil respiration (the release of carbon) rates, but also improves ...

  • Genome of nitrogen-fixing, soil-living bacterium sequenced

    A collaboration of researchers, which includes scientists at the Virginia Bioinformatics Institute (VBI) and Virginia Tech, have completed the genome sequence of Azotobacter vinelandii, uncovering important genetic information that will contribute to a more complete understanding of the biology of this versatile, soil-living bacterium. The work will help advance research on A. vinelandii's role ...

  • Do nanoparticles affect the health of the soil ecosystem?

    New research reveals that many microorganisms, including bacteria and protozoa, show little sensitivity to fullerene nanoparticles applied to soil samples. However, fast-growing bacteria decreased in number and the genetic diversity of bacteria and protozoa altered slightly. This could affect the bottom of the food chain, which may have long-term implications for the overall health of the soil ...

  • Mapping Earth`s soil moisture with NASA

    Professor Dara Entekhabi from the Massachusetts Institute of Technology is to lead a science team designing a NASA satellite mission to collect global soil moisture measurements and other data seen as key to improving weather, flood and drought forecasts and predictions of agricultural productivity and climate change. At present, scientists have no network for gathering soil ...

  • Soil CO2 emissions may continue for longer than previously thought

    Current models of soil carbon suggest CO2 emissions caused by rising temperatures will decrease over time. However, a recent study, which deliberately warmed soil for ten years, found no evidence of such a decline. The results indicate that our understanding of soil carbon dynamics may need revisiting. Soil is one of the most important carbon stores in the world. Just 0.1 per cent of carbon ...

  • Study helps clarify role of soil microbes in global warming

    Current models of global climate change predict warmer temperatures will increase the rate that bacteria and other microbes decompose soil organic matter, a scenario that pumps even more heat-trapping carbon into the atmosphere. But a new study led by a University of Georgia researcher shows that while the rate of decomposition increases for a brief period in response to warmer temperatures, ...

  • Common soil bacteria could clean up nuclear contamination

    Researchers are studying some common soil bacteria that “inhale” toxic metals and “exhale” them in a non-toxic form. The bacteria might one day be used to clean up toxic chemicals left over from nuclear weapons production decades ago. Using a unique combination of microscopes, researchers at Ohio State University and their colleagues were able to glimpse how the Shewanella oneidensis bacterium ...


  • Loss of soil carbon linked to climate change in England and Wales

    Soil and plants store around 5% of the world’s carbon, but carbon storage in some soils is in decline. Recent research has found that climate change accounted for 9–22% of carbon declines in organic soils in semi-natural habitats throughout England and Wales from 1978–2003. The researchers say monitoring soils rich in carbon should be a priority to ensure that more carbon is not ...

  • Puerto Rican Companies Turn to Zimmetry Environmental for Compliance with OSHA’s New Crystalline Silica Rule

    In March, the Occupational Safety & Health Administration (OSHA) issued their highly anticipated final rule to protect workers from exposure to respirable crystalline silica. OSHA estimates that the rule will save over 600 lives and prevent more than 900 new cases of silicosis each year, once its effects are fully realized. The Final Rule is projected to provide net benefits of about $7.7 ...

  • Management of rice paddy fields affects greenhouse gas emissions

    How rice paddy fields are managed significantly influences the release of greenhouse gases (GHGs), a recent study concludes. Permanently flooded soils release more methane than soils that are flooded and then dried between production periods, for example. In general, the researchers recommend growing other crops in dried soil between production cycles, as well as limiting nitrogen fertilisers, to ...

  • Mesothelioma risk and asbestos hazards prompt testing in Washington

    Due to the recent public health emergency declared in Libby, Montana, the Environmental Protection Agency (EPA) has begun testing residential yards near a former W.R. Grace & Company insulation factory in Spokane, Washington. EPA work crews are testing for the presence of asbestos, a toxic mineral associated with the development of malignant pleural mesothelioma. Vermiculite Northwest, which ...


  • NIOSH Posts Silicosis Update Highlighting the Need for Continued Worker Protection

    In June, the National Institute for Occupational Safety and Health (NIOSH) published a Silicosis Update.  It discusses how a wide range of workers in numerous industries are exposed to silica-containing dusts and new recently released data about silicosis.   The new data shows that the annual number of silicosis deaths declined 40% from 185 in 1999 to 111 ...

  • Rebuttal Regarding Regenesis EHC-O™ Claims

    Please find herewith as Appendix A, a copy of a letter dated March, 2007, by Mr. Scott B. Wilson, the current President & CEO of Regenesis. This enterprise was founded to commercialize ORC®; an oxygen release compound sometimes considered as an alternative technology to Adventus’ own EHCO™ oxygen releasing compound. It is our opinion that Mr. Wilson’s thesis is conspicuously written in the ...


  • California’s Prop 65 and Public Health Concerns over Crystalline Silica

    In 1986, California voters approved an initiative to address increasing concerns over exposure to toxic chemicals. That initiative, the Safe Drinking Water and Toxic Enforcement Act of 1986, is better known by its original name of Proposition 65.� Proposition 65 requires businesses to notify Californians about significant amounts of chemicals in the products they purchase, in their homes or ...

  • Macaulay Institute chooses Enviro Technology’s Picarro for their international research

    Leading Aberdeen based land-use research centre the Macaulay Institute has purchased two Picarro isotopic CO2 (Carbon Dioxide) analysers from Enviro Technology for its world-wide research programme. The analysers are being used for the Institute’s field campaigns, which look at the 13C isotope content of CO2 which leaves the soil surface. By measuring  the ...

  • Oldest trees are overlooked in the fight against climate change

    A new analysis shows that the role of old-growth or ancient forests in removing carbon from the atmosphere has been underestimated. The authors of the study suggest that such forests must be protected to aid the fight against climate change. Scientists have revealed that forests that are centuries old continue to remove carbon dioxide from the atmosphere. Up to now, the consensus was that these ...
