  • Managing Compostable Bags At Anaerobic Digestion Plants

    The highest and best use for treating residential food waste is through source separation, sending organics first to anaerobic digestion (to capture energy), followed by aerobic composting (to return nutrients to the soil). Sending food waste to anaerobic digestion (AD) facilities requires appropriate tools and planning for capturing high volumes of material with low contamination. Compostable ...

  • The Use of Models For Ecological Risk Assessment in Coastal Ecosystems: Thresholds Point of View

    Ecological Risk Assessment (ERA) can be defined as “the process for systematically evaluating how likely it is that adverse ecological effects may occur as a result of exposure to one or more stressors” (U.S. EPA, 1998). The idea of adopting ERA as a fundamental component in the management of ecosystems has gained an increased recognition due to the fact that it is impossible to eliminate all ...


  • ENVIRONMENTAL MANAGEMENT: Algae recruited for waterways clean-up

    Most people have heard about the canary in the cage; the hapless sentinel that warns miners of lethal build-ups of poisonous gas by falling off its perch, dead. Researchers have applied a similar principle to their development of a procedure for identifying and removing toxicants from estuarine and coastal waters, using highly sensitive algae as toxicity test subjects. The use of such ‘lower ...

  • Homeland Security for Drinking Water Supplies

    As it has done with other jurisdictions, Congress has recently passed legislation aimed at protecting our nation's drinking water resources. Historically, water supply protection has been a high priority, including reservoir protection, continuous monitoring, and secure and redundant facilities to ensure an uninterrupted supply of drinking water. The Clean Water Act (1972), requires pollution ...

HACH LANGE analysers therefore offer a range of options ...


  • Dialysis with a semipermeable membrane – a new sample-preparation technique for determination of Polybrominated Diphenyl ethers in fatty matrices

    Summary Dialysis with a low-density polyethylene semipermeable membrane (SPM) is an efficient means of removal of lipids in the determination of bioaccumulative, persistent, halogenated organic compounds. In this study an SPM was used for preconcentration of polybrominated diphenyl ethers (PBDE) from food samples. The method is useful for determination of PBDE and other halogenated ...

  • The toxic legacy of Thailand’s ‘Great Flood’ will remain long after the waters have receded

    This year’s unusually long rainy season has left many part of Thailand, Lao and Cambodia inundated and resulted in the worst flooding crisis in Thailand for at least 50 years. The provinces of the central plains and many districts in the north, east and west of metropolitan Bangkok are now effectively under water. The huge volume of floodwater is such that flood levels are 3 metres deep in ...

  • Survey on Existing Sample Archives For The Assessment of Time Trends of Pollutants in The Environment of New EU Member States and Candidate Countries

    Foreword Potentially high levels of chemical pollution in the EU+10 compared to the EU 15 Member States generate concern on the environmental status of the former. Especially contaminations in the agro-environment of the new EU MS may result in an increase of the overall human exposure in the enlarged EU. First attempts to collect concrete data on polychlorinated dioxins (PCDDs), -furans ...

  • A Trace of Arsenic

    The cans of baby formula invaded Brian Jackson’s Dartmouth College lab late in 2010. His team picked up an armful of popular brands at the food co-op in Hanover, N.H. Then another armload. Eventually Jackson had a cabinet full of the brightly labeled canisters. Today, he still keeps a few in his office. Not as clutter — that’s not his style. He just likes to keep his toxicology ...
