  • Carbon Sequestration: Addressing Climate Change and Food Security through Sustainable Agriculture

    Introduction To meet the demands of a growing, increasingly urban global population (approximately 9 billion by 2050), the World Bank calculates that global food production must increase by 70% in the next 35 years. This is a great challenge not only because of the volume of food that must be produced, but because agricultural conditions will not remain constant or predicable ...

  • Protecting and restoring forests

    Protecting the earth’s nearly 4 billion hectares of remaining forests and replanting those already lost are both essential for restoring the earth’s health, an important foundation for the new economy. Reducing rainfall runoff and the associated flooding and soil erosion, recycling rainfall inland, and restoring aquifer recharge depend on simultaneously reducing pressure on forests and on ...

  • A Decade After Asian Tsunami, New Forests Protect the Coast

    The tsunami that struck Indonesia in 2004 obliterated vast areas of Aceh province. But villagers there are using an innovative microcredit scheme to restore mangrove forests and other coastal ecosystems that will serve as a natural barrier against future killer waves and storms. On the day that the Indian Ocean tsunami hit his village a decade ago, fisherman Hajamuddin was at sea. It was ...

  • Statistical modelling of the hormetic dose zone and the toxic potency completes the quantitative description of hormetic dose responses

    Quantifying the characteristics of hormesis provides valuable insights into this low‐dose phenomenon and helps to display and capture its variability. A prerequisite to do so is a statistical procedure allowing to quantify general hormetic features, namely the maximum stimulatory response, the ‘dose range of hormesis’, and the distance from the maximum stimulation to the dose where hormesis ...

  • Using the Terrestrial Residue EXposure (T‐REX) model to assess threatened and endangered bird exposure to and risk from pesticides

    The Terrestrial Residue EXposure (T‐REX) model, a spreadsheet‐based model developed by the U.S. Environmental Protection Agency (USEPA), is used to estimate the concentrations of pesticides on some representative avian terrestrial food items following a foliar pesticide application. T‐REX uses 5 or 6 categories of food items to assess exposure for birds. Different body size classes are used to ...

  • Ecotoxicity of halloysite nanotubes supported palladium nanoparticles on Raphanus sativus L.

    Halloysite nanotubes (HNTs) are natural nanomaterials, biocompatible and available in large amounts at low prices. They are emerging nanomaterials with appealing perspectives for application like support for metal nanoparticles (NPs). Potential environmental impacts of NPs can be understood taking into consideration phytotoxicity. Current research focuses on HNTs application in cell or animal ...

  • Mixture toxicity and interactions of Cu, Ni, Cd and Zn to barley at low effect levels: Something from nothing?

    Metal contamination is mostly a mixture of different metals and these multi‐component mixtures can produce significant mixture effects. This study was set up to investigate toxicity of multiple metal mixtures of Cu, Ni, Cd and Zn to plants at metal doses individually causing low level phytotoxic effects. Barley (Hordeum vulgare L.) root elongation toxicity tests were performed in resin ...

  • Mixture toxicity of copper, cadmium and zinc to barley seedlings is not explained by antioxidant and oxidative stress biomarkers

    Metal mixture toxicity analysis to plants is complicated by mutual interactions. Here, mixture effects of zinc (Zn), cadmium (Cd) and copper (Cu) on barley (Hordeum vulgare L.) root elongation were analysed using oxidative stress parameters. The hypothesis was that toxic mixture effects on plant growth are better explained by biochemical parameters than by exposure information, because the ...

  • An Atlas of pan-European data for investigating the fate of agrochemicals in terrestrial ecosystems

    In 2000, with the enforcement of the Water Framework Directive (WFD) 2000/60/EC the European Commission established a framework for the protection of surface, subsurface and coastal waters. The WFD requires Member States to implement all necessary measures to prevent deterioration of the status of surface water bodies, and to protect and enhance the status of surface water bodies. This will also ...


  • Salmon aquaculture could incorporate seaweed and sea urchins to reduce nitrogen enrichment

    Farming fish together with seaweed and other species could help improve the sustainability of aquaculture and reduce pollution. A new study provides a tool for designing sustainable fish farming systems and calculates their potential to recycle waste. An example of a salmon farming system incorporating seaweed and sea urchins could reduce nitrogen releases to the environment by 45%. Over half of ...

  • Clean, green and powered by cow patties

    Two dome-like structures rise out of the thick ice fog of a Prairie winter day. From a distance, a science-fiction city seems to be taking shape on the rolling grasslands of east-central Alberta. Then, as you draw near, another sensation takes hold – the oppressively pungent odour of cow manure. On this day, the enveloping fog is making the smell worse than usual, explains Bern ...

  • Book Byte: We Can Reforest the Earth

    Protecting the 10 billion acres of remaining forests on earth and replanting many of those already lost are both essential for restoring the earth’s health. Since 2000, the earth’s forest cover has shrunk by 13 million acres each year, with annual losses of 32 million acres far exceeding the regrowth of 19 ...

  • Biomimicry: solutions hidden in plain sight

    Some call it arrogance, the way human beings believe it is possible to out-smart nature with science and technology. Now, Houston and other large cities deal with excessive water runoff as a result of cutting down forests and paving over prairie. The fish in most ...

  • Organics in Action : Sustainable Practices Thrive In A National Park

    The Presidio is part of California’s Golden Gate National Recreation Area and the national park system. As an urban park on the northern edge of San Francisco, there are many challenges to be met in the quest to be a model of sustainability. An innovative composting program is becoming one way to help meet the park’s goals. Nearing the close of its second year, this program is well on its ...

  • Continuous mixing systems for the production of pharmaceutical tablets and granulates

    The Process Analytical Technology initiative demands the implementation of in-process monitoring systems and controls along with the mixing process. Gericke has developed continuous mixing and metering systems that meet the stipulated accuracy and the highest hygienic requirements. Own testing and model calculations demonstrate that their efficiency is determined not only by ...

  • Ordinances To Amend Soils Boost Compost Demand

    Municipalities everywhere are realizing that some of the environmental issues they are grappling with locally may be mitigated by healthier soils. In the late 1990s, when Puget Sound Chinook salmon was listed as threatened, Washington State officials scrambled to find ways to improve water quality in the Puget Sound and protect spawning streams. They identified a number of methods to reduce ...
