Ozone pollution poses a significant health risk, especially for the elderly, young children, and those with respiratory difficulties. In addition, high levels of ozone can damage crops and forests.

Although it acts as a protective layer high above the earth, ground-level ozone can be harmful to breathe. Ozone is the prime ingredient of smog; it is not emitted directly into the air but rather is formed by gases called nitrogen oxides (NOx) and volatile organic compounds (VOCs). In the presence of strong sunlight, these gases react with oxygen in the air to form ozone concentrations that can remain high over large regions. Certain urban areas tend to have high ozone levels.

Ground-level ozone can be harmful to people and the environment. Levels above the health-based standards established by the U.S. Environmental Protection Agency (EPA) are known to cause chest pain, coughing, throat irritation, and congestion, and may also worsen bronchitis, heart disease, emphysema, and asthma. Healthy people as well as those with respiratory problems experience breathing problems when exposed to ozone.

Ozone is a gas that is formed in the atmosphere when three atoms of oxygen are combined. Ozone gas is not directly emitted into the air. There are chemical compounds, called precursors, which are emitted from both natural sources and human activities that react together to form ozone. These reactions are driven by light energy from the sun. Ozone is both a good and bad thing.

The depletion of the ozone layer leads, on the average, to an increase in ground-level ultraviolet radiation, because ozone is an effective absorber of ultraviolet radiation. The Sun emits radiation over a wide range of energies, with about 2% in the form of high-energy, ultraviolet (UV) radiation. Some of this UV radiation (UV-B) is especially effective in causing damage to living beings, for example, sunburn, skin cancer, and eye damage to humans.

According to research, at very high concentrations, ozone can be a lung irritant. Our ionic air purifiers should not be confused with ozone generators that hardly produce any negative ions. Our units will not create ozone levels higher than 0.04 ppm (parts per million), which is well within the FDA and OSHA safety standards and at levels shown to have beneficial effects against odors and microorganisms. Ozone at levels between 0.10 and 0.

Turn off lights in any room you are not using; reduce overall lighting. Use fluorescent fixtures rather than incandescent fixtures. Do not refuel your vehicle or lawn mower on Ozone Action Days. If you must, do so after dark - remember that sunlight assist ozone forming reactions.

Ground-level ozone is formed when nitrogen oxides (NOx) and volatile organic compounds (VOCs), such as xylene, react in the atmosphere in the presence of sunlight. NOx and VOCs are called ozone precursors. Motor vehicle exhaust, industrial emissions, and chemical solvents are the major sources of these chemicals. Ozone pollution is a concern during the summer months when the weather conditions needed to form it - lots of sun, hot temperatures - normally occur.

Stratospheric ozone or A good ozone @ is a layer surrounding the earths atmosphere. It protects all life on earth from the damaging effects of the sun = s rays. Ground level ozone is formed by a photochemical reaction between atmospheric oxygen (O2) and smog forming chemicals at the earths surface. It is odorless and colorless, but can have profound effects on the human respiratory system.

Ozone can be explained as "natures cleaning agent". If the pollutants are high, it is necessary for the ozone levels to increase proportionally. The National Weather Service issues OZONE ALERTS for heavy smog or pollution in the air. Many ionizer manufacturers downplay the ozone levels in ionization. The OSHA laws set specific limits for exposures to ozone (.04 parts per million is unhealthy). Pentex ionizers emit levels of .01 parts per billion, virtually undetectable!

The Environmental Protection Agency (EPA) released new Ozone standards. They established an 8-hour standard of 0.08 parts per million (ppm) and defines the new standard as a concentration-based form, specifically the 3-year average of the annual 4th-highest daily maximum 8-hour ozone concentrations. The EPA also stated, In setting the 8-hour standard at 0.

IN USA offers a wide range of ozone monitors and ozone analyzers. We have ozone monitors to measure the ozone levels in the ambient to detect leaks and ensure workplace safety from ppb to ppm levels. We have ozone monitors that measure the ozone concentration produced by the ozone generators from ppm levels up to 900 g/Nm3 or 26 %w/w. We have ozone monitors that measure ozone residual in liquid from ppb levels all the way up to several hundreds of ppm.

Rinks can be built on uneven ground. The instructions with the kit will show you how to level the border to compensate for the drop. It's very easy to do - but the greater the drop, the more preparation will be needed. Backyard rinks can have a maximum 10" drop from the high to low side - "municipal" rinks can handle an 8" drop.

Yes. After the shoe is nailed on, simply hold a plastic pad over the shoe and dispense the material at the heels, and fill it up to the heels or bulbs. Note: Equi-Pak Hoof Packing will adhere to Foam Boards, leather and rubber pads, as well as some types of polyethylene pads. Cover the pad where the Equi-Pak will contact it.

The radars produced about 10,000 watts, about the same as 15 microwave ovens. This power was spread out over an oval area about 6 X 20 kilometers (120 square kilometers or 30 square miles). The power measured on the ground was about one 50,000th the level of a radio station and about one ten millionth the level of a cell phone. In addition, SRTM only illuminated a given area for about 1/10 of a second. The microwaves were emitted in a very narrow beam, which never came close to the orbiter.
