  • ALKION column and eluant system

    Introduction: The stationary phase in the ALKION column is a rigid, non-porous polymeric phase that is surface sulfonated. The two modes of separation are ion-exchange and moderate partitioning. The low capacity of the ion-exchange resin makes it an ideal phase for the separation of strongly basic and positively charged compounds. The reversed-phase character allows for ...

  • Comparison of Reducing Agents for Dechlorination in a Simulated Aquifer (PDF)

    A simulated aquifer system (Aquifer Simulation Vessel – ASV) was used to study the efficacy of various reducing agents to assist microbial dechlorination. The soil samples are homogenized and the soil is packed into 6.0-foot long tubes with an internal diameter of 5.75 inches. Flow rates can be calibrated for flow at 0.1 to 2.0 feet/day. The system has a volume of 2025.44 in3.  A solution of ...

  • Rt-Ribosyn – A New Method to Measure the Specific Growth Rates of Distinct Microbial Populations in Engineered Systems

    ABSTRACTA molecular biology based method called RT-RiboSyn has been developed to measure the specific growth rate of microbial populations. This method analyzes culture samples that have been exposed to chloramphenicol for defined times. Chloramphenicol disrupts ribosome synthesis, which causes a buildup of the level of precursor 16S rRNA within the cells. Specific microbial populations can be ...

  • Performance-Based Measurement Systems

    Many of the Environmental Protection Agency's (EPA's) methods used to monitor air, water and soil for environmental contaminants prescribe step-by-step details on how the chemical analysis must be conducted and prohibit any deviations or variations. The EPA has recognized that monitoring equipment and technology have improved tremendously over the last few years; that environmental media do not ...

  • Monitoring Environmental Quality

    ' In order to determine the effectiveness of actions to improve environmental quality it is necessary to be able to measure relevant environmental parameters at a level of detail which is accurate enough to distinguish the anticipated changes. However, the establishment and maintenance of monitoring systems is time-consuming and expensive and therefore the scale of such systems needs to be kept ...

  • Least-Cost Approaches to Reducing Acid Emissions

    ' The costs of meeting sulfur emission targets can be high. It is essential, therefore, that countries adopt policies which (a) minimize the net economic and social costs of reducing emissions to the agreed target levels, and (b) maximize the overlap between measures designed to reduce acidifying emissions and those addressing other forms of air pollution. This note discusses alternative ...
