  • Sample Handling Strategies for Accurate Lead-In-Soil Measurements in the Field and Laboratory

    ABSTRACT The inhomogenous lead-in-soil matrix can present serious obstacles to accurate sample collection and handling. In typical lead-in-soil measurement, particle size related errors in sampling and sample handling often exceed all other sources of error. The magnitude of error can vary widely depending on the particulate nature of the lead contaminant and the effectiveness of control ...

  • The Five Factors of Smart Laboratory Success

    The Five Factors Research organizations are under pressure to cut costs while maintaining or increasing throughput. To improve their operations, many laboratories are considering investments in data management or support and automation systems like ELNs, LIMS or Robotics/HTS. Whatever the change that is introduced, there are many pitfalls on the way to delivery, roll-out and ...

  • Chronic sensitivity of White sturgeon (Acipenser transmontanus) and rainbow trout (Oncorhynchus mykiss) to cadmium, copper, lead, or zinc in laboratory water‐only exposures

    Chronic toxicity of cadmium, copper, lead, or zinc to White Sturgeon (Acipenser transmontanus) and Rainbow Trout (Oncorhynchus mykiss) was evaluated in water‐only exposures started with newly hatched larvae or about 1‐month‐old juveniles. The 20% effect concentration (EC20) for cadmium from the sturgeon tests was higher than the EC20 from the trout tests, whereas the EC20 for copper, lead, or ...

  • CU-Boulder leading study of wind turbine wakes

    While wind turbines primarily are a source of renewable energy, they also produce wakes of invisible ripples that can affect the atmosphere and influence wind turbines downstream -- an issue being researched in a newly launched study led by the University of Colorado Boulder's Julie Lundquist, assistant professor in the atmospheric and oceanic sciences department. The study, called the Turbine ...


  • Get the Lead Out - Standards Aid in RoHS Compliance

    RoHS, the seminal European sustainability directive, and others like it challenge manufacturers to eliminate hazardous substances in their products. With RoHS compliance deadlines ongoing through at least the next five years, and more to come from other regions and nations, ASTM Committee F40 is helping companies with testing standards and other resources. The recent introduction of the new Apple ...

  • Together we can get the lead out

    If there is one lesson to be learned from the Flint crisis, it is this: Our communities will be safer in the long run with no lead pipes in the ground. That’s why the board of the American Water Works Association – recognizing our first core principle is the protection of public health -- voted unanimously on March 7 to forge on a path toward the removal of all lead service lines. ...

  • Leading Corporate Strategies and Climate Change - CEO Table

    I’m an avid gardener. I revel in spending an afternoon under the warmth of the sun getting my hands into the soil, re-planting flowers, nurturing the unhealthy and staking blossoms. It is a time when good ideas seep into my mind and badideas creep out. It is my learning laboratory. One of the many things that my garden has taught me is that the plants fallinto three growing categories: those that ...

  • The AIJ pilot phase as laboratory for CDM and JI

    The Activities Implemented Jointly (AIJ) program has developed about 150 greenhouse gas reduction and sequestration projects in many economic sectors in over 40 countries during the last six years. Most of these projects are rather small and many of them have only been partially implemented due to lack of finance. The lack of emissions credits is the main reason. Only half a dozen investor ...

  • Extraction of lead and cadmium from soils by Cysteine and Glutathione

    Received for publication December 17, 2008. Metal-thiol complexes can enhance metal uptake by plant roots and microorganisms, therefore it is important to determine whether thiols effectively solubilize these metals from the soil matrix. Extractions were conducted by combining 1 g contaminated soil and 10 mL of 10 mmol L–1 thiol solution and shaking for 1 h. Both cysteine and glutathione ...
