  • A Critical Evaluation of the South African Air Quality Offsets Guideline

    There is wide recognition in South Africa to the link between the quality of life and quality of the air we breathe. The Department of Environmental Affairs (DEA) attempts to improve air quality through two key regulatory tools; emission limits, which regulate the maximum concentration of certain pollutants permissible within certain, ‘listed’ industrial stacks or vents, and ambient ...

  • Wind Energy Production Estimates: Moving Beyond Time Averages

    No need to be a statistician to see that averages are often useful to compare different things. And yet, they often fall short as a true measure of performance. For instance, we use averages to compare the current weather against the climate normals or to get a sense of how our favorite sport team or player is doing. Team (player) statistics are a concise way of combining the scores from many ...

  • Get the Lead Out

    EPA rethinks air quality standards, seeks comments.  By any independent standard, the federal government has made significant progress in reducing lead concentrations in ambient air. Average lead concentrations have dropped 96% since the 1980s, primarily due to the ban on lead in motor vehicle gasoline. Since the late 1970s, bloodlead concentrations for children ages 1 to 5 have decreased ...

  • Lead in the environment and in drinking water

    Everywhere you look metal lead is in the headlines. The majority of the recent press attention however, has not focused in lead in contaminated water, air, or soil but rather on high concentrations of lead found in toys and children?s jewelry that have been produced in developing countries where lax standards apply. Regardless of the particular source of lead contamination, the fact is lead can ...

  • The history of leaded gasoline

    Forensic investigations are often a combination of both scientific techniques and historical background studies. One example that is often used is the background to leaded gasoline. Gasoline service stations can be found on many street corners and, in fact, there were many more service stations in the United States in the 1960s than there are today. This means that potential sources of ...


  • Getting the lead out — at the faucet

    You might be surprised at where you’ll find a customer’s lead. Lead is making headlines. First, we should note that the current attention is not due to water, air or soil contamination, but from lead contamination recently found in toys and children’s jewelry made in China. This is very frightening for any parent because of the harm lead can to cause in children. How could this happen? How ...

    OEM reduces engineering costs by 50 percent through standardizing on the Rockwell Automation® Logix control BACKGROUND According to the United States Environmental Protection Agency (EPA), each year millions of tons of air toxins are released into the air, mostly from man-made sources. Anguil Environmental Systems Inc., a Milwaukee-based air pollution ...

  • Rethinking the California Air Resources Board`s ozone standards

    The California Air Resources Board (CARB), California’s state air-pollution regulatory agency, recently adopted the most stringent ozone air-pollution standard in the United States. Attempting to attain the new standard will impose great hardship on Californians in exchange for small and imperceptible health benefits.By CARB’s own estimates, the incremental benefits of attaining its new ...

  • Lead in Paint and Soil in Karnataka and Gujarat, India

    Blood lead surveys in several areas of India have found very high percentages of children with elevated blood lead levels. Fifty-three percent of children under 12 years of age in a sevencity screening had blood lead levels equal to or greater than 10 μg/dL, the level currently considered elevated by the U.S.  Centers for Disease Control and Prevention (CDC). A number of these surveys ...

  • 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 ...


  • Comparison of two standard odor intensity evaluation methods for odor problems in air or water

    Government agencies responsible for ensuring healthful water and/or air quality are often faced with resolving public complaints of nuisance odors. Understanding variations in odor intensity may ultimately lead to the establishment and application by such agencies of quantitative limits for effective odorant control. An odor panel was trained in suprathreshold odor intensity evaluation using ...

  • Expanding lead monitoring in support of EPA`s revised NAAQS

    On October 15, 2008, the U.S. Environmental Protection Agency (EPA) substantially strengthened the National Ambient Air Quality Standards (NAAQS) for lead. The revised standards are 10 times lower than the previous standards and will improve health protection for at-risk groups with a particular focus on children. In conjunction with this strengthening of the lead NAAQS, EPA changed the existing ...

  • 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 ...
