  • Eliminating Man-Made Hazein Protected Areas: A Goal of the Regional Haze Rule

    In recognition of the value of good visibility in areas set aside for their scenic splendor, Section 169A of the 1977 U.S. clean Air Act Amendments established a national goal of remedying existing visibility impairment and preventing future visibility impairment resulting from man-made air pollution emissions at 156 national parks and wilderness areas, referred to as visibility-protected federal ...

  • Advantages of using the Ecotech three wavelength nephelometer for aerosol measurements

    The measurement of the scattering properties of aerosols is limited by the errors introduced by typical single wavelength integrating nephelometers. These limitations, however, can be reduced by implementing the features of the Ecotech Three Wavelength Integrating Nephelometer. These limitations are predominantly contributed by particle size, relative humidity, Lambertian distribution of the ...

  • Nordre Follo, Oslo, Norway municipal case study

    Challenge In 1993 the Norwegian Pollution Control Authorities instructed Nordre Follo WWTP to reduce their effluent discharge of nitrogen, BOD and phosphorus. The new effluent requirements were as follows: Phosphorus: 90% removal (annual average) Maximum - 0.6 mg/L Average - 0.3 mg/L Nitrogen: 70% removal (annual average) ...

  • Cost Savings: Setting and Meeting Targets

    Introduction SC Johnson, family-owned and family-managed for 112 years, has a long history of responsible environmental management.  Sam Johnson, owner and chairman, made history in 1975 by announcing his company's voluntary and unilateral decision to eliminate CFC propellants from its aerosols worldwide--the first company to do so.  It is not surprising that this global manufacturer ...


  • Engine detonation with bioethanol cavitation

    Bioethanol is an alcohol of an organic origin which receives from a sugar ferment reaction. In the process of ethanol formation, starch from grains of plants turns in simple sugar in reaction with enzymes. Natural sugar ferments with yeast and form a mix of alcohol, water and unfermented remains. Alcohol is separated from a mix in distillation capacities and additionally clears in rectifying ...

  • How to reverse the causes of ozone layer destruction

    Since the causes of ozone layer depletion were identified, solutions were put into place to reduce or eliminate their usage. The U.S. Clean Air Act and the Montreal Protocols address the problem internationally. The goal of these treaties is to stop the damage to the ozone layer by phasing out known contributors.Although there are numerous causes of ozone layer depletion, chloroflurocarbons have ...

  • 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 ...
