NAIROBI, Kenya (Reuters) Illegal trade in ozone-depleting substances (ODS) is rising as the deadline for zero production and consumption of such chemicals draws closer, a London-based lobby group said on Monday. The Environment Investigation Agency (EIA) released a report at the United Nations Environmental Programme headquarters in Nairobi showing trends in global chlorofluorocarbons (CFCs) smuggling and the need for faster phase out under the Montreal Protocol. The protocol requires signatory states to phase out the use of some 95 chemicals blamed for damaging the ozone layer, a stratum of the atmosphere that protects the earth from ultraviolet radiation, which can cause skin cancer. But some countries, especially developing nations, have not yet complied with the protocol, which commits them to phasing out CFCs often used in refrigerators and other chemicals by certain dates.

Extractions: NATIONAL SCIENCE AND TECHNOLOGY COUNCIL COMMITTEE ON ENVIRONMENT AND NATURAL RESOURCES FACT SHEET NORTH AMERICAN RESEARCH STRATEGY FOR TROPOSPHERIC OZONE RESEARCH INITIATIVE Activities under the National Science and Technology Council (NSTC) The NSTC's Committee on Environment and Natural Resources (CENR) identified ground-level ozone as an initiative in 1995. A signing ceremony for the charter of the North American Research Strategy for Tropospheric Ozone (NARSTO) was held at the White House in February of that year. The establishment of NARSTO is a direct response to the identification by the National Research Council (NRC) of the need for a better fundamental understanding of urban and regional ozone and its call for a coordinated national program. In addition to coordinating funding for field research, NARSTO is currently preparing a State-of-Science Assessment that will comprehensively review advances in the chemical, physical, and meteorological science of tropospheric ozone. Throughout 1997, seventeen critical review papers will be prepared by experts in the relevant research areas. These will be presented at a NARSTO Science Symposium to be held in November 1997 and will also appear in a special issue of an air quality scientific journal. The Assessment Report, which will synthesize the review papers, is scheduled for completion by the end of December 1998. It will address how recent scientific progress can be used to develop improved options for ozone management. U. S. Federal agencies participating in NARSTO include the Departments of Agriculture, Commerce (National Oceanic and Atmospheric Administration), Energy (Office of Energy Research), the Interior, and Transportation, as well as independent agencies, such as the Environmental Protection Agency, the National Science Foundation, the National Aeronautics and Space Administration, and the Tennessee Valley Authority.

http://www.environment.no/templates/themepage____2144.aspx

Extractions: The ozone layer is still being depleted, but recent measurements suggest that concentrations of ozone-depleting substances in the atmosphere have peaked and begun to drop. Consumption of these substances is dropping rapidly in Norway and in the world as a whole, and concentrations in the atmosphere are expected to be back to the 1980 level by 2050. The ozone layer is expected to recover significantly by 2050, however the greenhouse effect may slow down this process. The ozone layer is found in the stratosphere, 15-35 km above the surface of the earth. Ninety per cent of the ozone (O3) present in the atmosphere is concentrated here. Ozone is continually generated and broken down through natural processes in the stratosphere. Anthropogenic emissions of ozone-depleting substances have disturbed the balance in the stratosphere. Measurements have shown a decline in global stratospheric ozone levels over the last 20 years. Since 1969, the global average loss of ozone has been 5 per cent at middle-latitudes. Ozone-depletion of up to 10 per cent during winter and spring and up to 5 per cent in summer and autumn has been recorded over Europe, North America and Australia. If we ignore the effect of other factors that influence the ozone layer, such as climate change and volcanic eruptions, it seems probable that the ozone layer is now at its thinnest.

http://www.environment.no/templates/PageWithRightListing____2142.aspx

Extractions: The earth's climate has become noticeable warmer during the past hundred years. Unless emissions of greenhouse gases are reduced, we risk major climate change and serious environmental problems in the future. Many industrial countries, amongst them Norway, have ratified the Kyoto Protocol, agreeing to reduce their overall greenhouse gas emissions. Norway has committed to stabilising emissions at 1 per cent above the 1990 emission level. The norwegian greenhouse gas emissions rose by 6 per cent from 1990 to 2002. Without new measures the emissions are expected to increase by 22 per cent during the period 1990 - 2010. Included in this figure are the emissions from two planned gas-fired power plants. During the past 20 years, man-made chemicals have reduced the amount of ozone in the stratospheric ozone layer. Depletion of the ozone layer allows larger doses of harmful ultra-violet (UV) radiation to reach the surface of the earth and increases the risk of skin cancer and infectious diseases. More than 160 countries have signed the 1987 Montreal Protocol, in which they agreed to phase out the use of substances that deplete the ozone layer. If all these countries achieve their targets, the ozone layer will probably return to normal by about 2050.

Extractions: Home About ELC Site Map Contact Us ... Food The primary component of photochemical smog is ozone. Ozone (O ) is not emitted directly into the air. It is formed through a complex series of reactions from nitrogen oxide, volatile organic compounds, and sunlight during periods when temperatures are elevated. Ground-level ozone levels increase in the spring and summer when there is more sunlight and temperatures are higher. Formation of ozone is lowest in the morning and highest in the late afternoon when sunlight intensity and temperature peak. Ozone breaks down quickly when the sun goes down, and does not accumulate from day to day. This is why, on Ozone Action Days (see below), public officials often request that certain activities, such as filling a gas tank, be postponed until after sundown. Issues concerning ozone near the surface of the earth (ground-level, or tropospheric ozone) should not be confused with those concerning ozone in the upper level of the atmosphere, the stratospheric ozone layer. At the ground-level, ozone is considered a pollutant, and can cause damage to human respiratory systems, plant life and man-made materials such as plastic and rubber. The stratospheric ozone is a layer of gas that begins about 10 miles above the surface of the earth. The stratospheric ozone layer surrounds and protects the earth from the sun's ultraviolet rays.

Insects Home Eastern Wildflowers General Topics Natural History Ecology Family Environment Evolution Home Education Home Conservation Geophysics Paleontology Commercial Organizations Return to Geophysics Main Page About 90 percent of the earth's ozone molecules are concentrated in a layer of the stratosphere called the "Ozone Layer". Stratospheric ozone is a naturally occurring gas that filters the sun's ultraviolet (UV) radiation. A depleted ozone layer allows more radiation to reach the Earth's surface. Among other problems overexposure to UV rays can lead to skin cancer, cataracts, and a weakened immune systems in humans. Increased UV can also lead to reduced crop yields and disruptions in the marine food chain. Ozone depletion is caused by the release of chlorofluorocarbons (CFCs) and other ozone-depleting substances (ODS), which were used widely as refrigerants, insulating foams, and solvents. Although CFCs are heavier than air, they are eventually carried into the stratosphere in a process that can take as long as 2 to 5 years. When CFCs reach the stratosphere, the ultraviolet radiation from the sun causes them to break apart and release chlorine atoms which react with ozone, starting chemical cycles of ozone destruction, and depleting the ozone layer. One chlorine atom can disassociate more than 100,000 ozone molecules.

ANSWER: QUESTION: I HAVE NOTICED THAT SOME WEB SITES CLAIM THAT THE OZONE GENERATORS THEY SELL DO NOT PRODUCE NITROGEN OXIDE, DO YOURS? ANSWER: Do not believe claims about corona discharge ozone generators that claim "zero" or "no nitrogen oxides". ALL CORONA DISCHARGE OZONE GENERATORS CREATE A SMALL AMOUNT OF NITROGEN OXIDES" unless they use pure oxygen for feed gas and have absolutely no steel of any kind in the generation chamber. The amount produced is negligible, approximately 1/100 of the amount of ozone being produced. In an ozonated area that is safe to occupy (>0.04 ppm) the nitrogen oxide level would be around 0.0004, well below the safe level. Some companies have used a testing method that does not work, Draeger gas testing tubes and Matheson gas detector tubes for nitrogen are not usable in an ozone environment. Both companies state in their instructions that they will not give an accurate reading in an ozone environment. Draeger say's that the nitrogen oxide tests are "not compatible with an ozone environment" and Matheson states that "the stained layer is decolorized by ozone"
