  • Ozone-depleting substances 2014

    Aggregated data reported by companies on the import, export, production, destruction, and feedstock and process agent use of ozone-depleting substances in the European Union Background The Montreal Protocol on Substances that Deplete the Ozone layer, which entered into force in 1989, aims to protect the stratospheric ozone layer by phasing out more than 200 ...

  • Monitoring of petroleum hydrocarbon degradative potential of indigenous microorganisms in ozonated soil

    This study was performed to investigate the petroleum hydrocarbon (PH) degradative potential of indigenous microorganisms in ozonated soil to better develop combined pre-ozonation/bioremediation technology. Diesel-contaminated soils were ozonated for 0–900min. PH and microbial concentrations in the soils decreased with increased ozonation time. The greatest reduction of total PH (TPH, 47.6%) and ...

  • Production of ozone in the Chamonix Valley (France)

    In the framework of the Pollution of Alpine Valleys (POVA) programme, a numerical investigation aims to better understand how a reduction of traffic emissions can affect air quality in the Chamonix Valley (France). The MM5 model coupled with the Chemistry Transport Model (CTM) TAPOM using a 1-km cell grid for the period 5–12 July 2003 showed that the ozone formation in the Chamonix Valley was ...

  • Automatic Ozone Mapping in France with ISATIS

    In France, air quality data are acquired by associations in charge of the air quality monitoring (Agences Agréées pour la Surveillance de la Qualité de l’Air - AASQA) These associations use the automatic procedures of ISATIS to daily update the pollution maps they publish on their websites. These automatic procedures make use of batch and allow to save time in the cartography because they enable ...

  • The CaroMont Health Ozone Laundry System

    Abstract Ozone generating equipment was retrofit into the laundry washroom of the Gaston Memorial Hospital in Gastonia, NC, and began operating in the early part of July, 2010. Three ozone generating systems service six washer-extractors in the washroom. The performance of this fine-bubble ozone diffusion laundering system has been monitored since that time, with various adjustments made ...

  • U.S. EPA Propses Revisions to Ozone NAAQS

    In May 2008, states, environmental groups, and industry groups filed petitions with the D.C. Circuit Court of Appeals (Court) for review of the 2008 ozone standards.  In March 2009, the Court granted a U.S. EPA request to stay the litigation so that the Obama administration could review the standards and determine whether they should be reconsidered. On September 16, 2009, U.S. EPA announced ...

  • Sophisticated control system - effective ozone generator

    At the Freshwater Institute in Shepherdstown, West Virginia (USA) they are convinced that ozone water treatment is essential to optimize production in water recirculating aquaculture systems (RAS). Scientists at the Freshwater Institute have been studying ozonation for years but have never before used such a sophisticated ozone generator as the Primozone® Ozone Generator. The Freshwater ...

  • Bio-fouling control on marine vessels with ozone

    A recent pilot study on how to control accumulation of marine organisms on heat exchangers of marine vessels show that applying ozone is both effective and sustainable. Large economic impact Marine bio-fouling, or accumulation of marine organisms on heat-exchangers for cooling systems, is a challenge in the maritime sector and has both an economic and environmental impact. Worldwide ...

  • Air pollution by ozone in Europe in summer 2005

    Ground-level ozone is one of the air pollutants of most concern in Europe. Ozone pollution is produced by photochemical processes involving nitrogen oxides and volatile organic compounds in the lower parts of the atmosphere. Ozone levels become particularly high in regions close to high ozone precursor emissions and during summer when stagnant meteorological conditions with high insolation and ...

  • EPA enforcement of the ozone depleting substance (ODS) regulations

    Is Your Organization Flirting With EPA Compliance Risk? The EPA Enforcement Office will issue fines for undocumented refrigerant gas usage as it relates to ozone depleting substances. Do you know how to mitigate this compliance risk? The phase-out program of refrigerant gas is now in full swing and facilities that use equipment requiring the use of ozone-depleting substances (ODS) are at risk for ...

  • Determination of transport processes of nocturnal ozone in Istanbul atmosphere

    Ozone, usually having a minimum value at night, often increase its concentration level which is known as nocturnal ozone. In this study, the magnitude, frequency and timing of nocturnal ozone maxima were determined between May and September for four years (2001-2004) for stations in the Asian and European sides of Istanbul, Turkey. The magnitude and frequency of late and early peaks for peak ...

  • Impacts of Ozone Nonattainment Designation and Strategies for Compliance

    In 1997, the U.S. Environmental Protection Agency (U.S. EPA) revised the National Ambient Air Quality Standards (NAAQS), to include an 8-hour ozone standard. The previous 1-hour ozone standard addressed the effects of exposure to short periods of high concentrations of ground-level ozone. The intent of the new standard is to address exposure to lower ozone levels over longer durations. With the ...
