  • A biofilm microreactor system for simultaneous electrochemical and nuclear magnetic resonance techniques

    Nuclear magnetic resonance (NMR) techniques are ideally suited for the study of biofilms and for probing their microenvironments because these techniques allow for noninvasive interrogation and in situ monitoring with high resolution. By combining NMR with simultaneous electrochemical techniques, it is possible to sustain and study live biofilms respiring on electrodes. Here, we describe a ...

  • How Shasun maximises the investment in it`s biological wastewater treatment plant

    At the Dudley Shasun facility we have a 7500 m3 biological treatment plant that can treat up to 36 tonnes of waste COD per day. Part of this capacity is utilised to treat up to 15 tankers per day of third party aqueous waste. The waste is very varied, covering everything from leachates at only 2000ppm COD to industrial waste at up to 500,000ppm COD. The Strathkelvin respirometer forms a central ...

  • Assessment of ambient air quality in Bishnumati corridor, Kathmandu metropolis

    The Kathmandu valley urban area is growing as a metropolis. Bishnumati corridor in Kathmandu valley is is a target of increased pollution. The unabated solid waste land-filling on either side of the river-bank and animal slaughter houses and biological waste arising from these activities, busy commercial and high residential density characterize the corridor. Six areas, namely Teku Dovan, ...

  • Demonstration of DeconGel at Oak Ridge National Laboratory building 2026

    Challenge In 2003 an area behind the hot cells in Building 2026 at the Oak Ridge National Laboratory (ORNL) was flooded with highly contaminated liquids when a liquid low level waste pipe became clogged. The main contaminants of concern are uranium and plutonium. Transferrable contamination levels are in the 1,000,000 disintegrations per minute range. The area is posted as an airborne ...

  • Mercury Spill Control Procedures

    Mercury is a dangerous neurotoxin that can have damaging affects on both the central nervous system and renal system of humans. Exposure to mercury can cause serious developmental delays in children, and high level exposure is life threatening. When exposed to air, mercury vaporizes, readily becoming a dangerous aerosol that can be absorbed into the lungs and spread throughout the body. This is ...


  • Mercury spill control procedures - industrial hygiene news

    Mercury is a known neurotoxin that is extremely toxic even in small amounts. It directly affects the central nervous and renal systems, causing developmental delays, motor and brain problems like those associated with autism. Mercury’s hidden danger also lies in when at room temperature, when exposed it vaporizes readily. Once it has become an aerosol, it is absorbed into the lungs and ...


  • EPA Proposes SNUR for Functionalized Carbon Nanotubes (Generic)

    On October 27, 2016, the U.S. Environmental Protection Agency (EPA) proposed significant new use rules (SNUR) for three chemical substances that were the subject of premanufacture notices (PMN), including functionalized carbon nanotubes (generic). According to the notice, the PMN states that the substance will be used as a thin film for electronic device applications. Based on structure-activity ...
