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.

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. See similar questions...

Excessive drinking both in the form of heavy drinking or binge drinking, is associated with numerous health problems, including but not limited to Chronic diseases such as liver cirrhosis (damage to liver cells), pancreatitis (inflammation of the pancreas), various cancers, including liver, mouth, throat, larynx (the voice box), and esophagus, high blood pressure, and psychological disorders.

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. See similar questions...

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! See similar questions...

In tests that do use ionizing radiation, the dose is usually very small, and is often similar to what you would get from natural background radiation in everyday life. As an example, a dose for a typical X-ray procedure might be 30 - 1,000 mr. Despite extensive study of the effects of radiation, direct evidence does not show that these doses are harmful to humans.

Trans fats can raise the level of low-density lipoprotein (LDL) cholesterol (also called the ??bad?? cholesterol) of our body, while at the same time lower the level of high-density lipoprotein (HDL) cholesterol (also called the ??good?? cholesterol). This increases the risk of coronary heart disease, which is the second killer in Hong Kong . See similar questions...

No. FDA and UL specify that ozone should not exceed 50 parts per billion (ppb). Kronos™ products have been designed to ensure ozone is minimized to less than 50 ppb regardless of the room size in which a Kronos™ product may be used. More specifically, Kronos™ products are subject to section 37 of the Electrostatic Air Cleaner Standard, UL 867 (an ozone performance test in a 100 square foot room for 24 hours is conducted before Kronos obtains UL approval for each product).

No. They are designed to produce between 0.02 ppm and 0.04 (max) ppm. This is within FDA and OSHA safety standards of 0.05 ppm. At this level, the ozone will be safe, effective, and pleasant, and may only be barely detectable. Ozone will not reach a point where it could be considered even a minor lung irritant until it reaches 0.1 to 0.2 ppm. Neo-Tec Ionizer purifiers stay within the 0. See similar questions...

EPA's answer: "The same chemical properties that allow high concentrations of ozone to react with organic material outside the body give it the ability to react with similar organic material that makes up the body, and potentially cause harmful health consequences. When inhaled, ozone can damage the lungs. Relatively low amounts can cause chest pain, coughing, shortness of breath, and, throat irritation. See similar questions...

Suspended particulate matter (PM) is an air pollutant derived from the combustion of fossil fuels in the form of dust, soot, or smoke. Diesel engines account for about one quarter of the particulate air pollution from all on-road sources. More than 98 percent of the particles emitted from diesel engines are fine particles, less than 1 micron in diameter, which can bypass respiratory defense mechanisms and penetrate deep into the lungs. See similar questions...

Nitrogen oxides (NOx) are a family of reactive gaseous compounds that contribute to air pollution. NOx emissions are produced during the combustion of fuels at high temperatures. Nitrogen oxides can irritate the lungs, cause bronchitis and pneumonia, and lower resistance to respiratory infections. They are an important precursor to both ozone and acid rain, and may affect both terrestrial and aquatic ecosystems.(5) See similar questions...

Styrene is not harmful in the very small amounts most people might sometimes encounter in air or food. Someone working with resin solutions containing styrene (patching the surface of a fibreglass boat, for example) may find the odour of styrene causes slight nausea if instructions to ensure adequate ventilation are not heeded. This goes away with exposure to fresh air, and there is no lasting effect. with all chemicals it is important to control one's level of exposure to the product. See similar questions...

If the water is discoloured you should not assume that it is safe to drink until you have sought advice from your water company. If the discolouration is due to mains deposits, these are mostly iron and manganese as such are not likely to be harmful to your health. However you may not wish to drink the water, or give it to your family, because it looks or tastes unpleasant. See similar questions...

unstable, poisonous allotrope of oxygen, O3, which is formed naturally in the ozone layer, is also produced in the lower atmosphere by the photochemical reaction of certain pollutants. Electrical appliances, especially those in the office, emit unhealthy amounts of ozone. When inhaled, ozone can damage the lungs. Relatively low amounts can cause chest pain, coughing, shortness of breath and throat irritation. See similar questions...

Ozone can irritate the respiratory system, causing coughing, throat irritation, and/or an uncomfortable sensation in the chest. Ozone can reduce lung function and make it more difficult to breathe deeply and vigorously. Breathing may become more rapid and shallow than normal. This may limit a person's ability to engage in vigorous activities. Ozone can aggravate asthma. When ozone levels are high, more people with asthma have attacks that require a doctor's attention or use of medication. See similar questions...

The 8-hour average ozone National Ambient Air Quality Standards is a health-based standard. According to former Environmental Protection Agency (EPA) Administrator Carol Browner in testimony before Congress[21], this standard is the product of "one of the most thorough and extensive scientific reviews ever" conducted by the EPA.
