Evil 10 to 10 common indoor air quality conditions plaguing Us All
Mold and water damaged building materials
When there is leakage resulting in mold growth which in turn causes the release of pungent and irritating volatile organic compounds, and allergenic mold spores in air. People with allergies or asthma often have reactions to these pollutants in the air while others may have no reaction. People with immune systems committed, they can even get infections from some molds. Some common mold infections are associated with chronic allergic fungal sinusitis, it is an allergic reaction, such as infection and that the results of spores germinating in the sinuses, the agent of infection is usually cast Alternaria spores. Other people may develop lung infections caused by certain species of Aspergillus growing in the lungs. Fungal infections are a product of an ill health person that the environment they are in. Home inspectors, mold inspector s the creation of other investigators may use a moisture meter to detect hidden moisture inside water damaged building materials.
Infrared cameras can also be used to detect hidden moisture in walls and other areas by measuring very slight temperature differentials between cooler wet surfaces warm, dry surfaces. Where mildew is moisture is often not far away. Drying the water within 24 to 48 hours and repairing leaks can go a long way in prevention of mold problems.
Dust mites and dust particles
Air contaminated with excess particles can also cause negative reactions. Some particles cause direct irritation when levels are high. In the case of house dust people do not usually have an allergen, directly or irritation related reaction. Common dust is as much as 80% of dead cells from human skin so the powder itself is seen as a forging invader by your body. When people have allergic reactions to common household dust, dust is not causing the problem but allergenic proteins found in the feces of dust mites. The particle counters can be used to measure airborne particles, particle counters are scientific instruments using a highly sensitive laser internal to count the particles passing through it which are of a certain size range. Good quality filters with tables in his statement of AC unit can help reduce dust, also use a good quality vacuum cleaner is equipped with a HEPA filter. A vacuum cleaner to remove bad the dust from your carpets then blow into his face.
Carbon dioxide
High levels of carbon dioxide are not usually a direct threat to health human in the household and commercial properties. High levels of carbon dioxide usually indicate a lack of adequate outdoor air entering the building. The dust, chemicals, body odors and other indoor air pollutants often accumulate along with the carbon dioxide in poorly ventilated buildings, and it is these other pollutants giving rise to complaints of indoor air quality and health complaints. According to Parat and others "A properly maintained and operated mechanical ventilation system can reduce concentrations Indoor bioaerosols by limiting the infiltration of outdoor Bioaerosols and by diluting the outdoor sources (Parat et al., 1994, 1996).
By American Society of Heating Refrigeration and Air Conditioning Engineers ASHRAE 62-89 outdoor air supply in the building must be at least 20 cubic feet per person per minute in the offices and thus help maintain carbon dioxide levels below 1000 ppm. The new requirements of recommendations for no more than 700 levels ppm of carbon than outdoor levels of carbon dioxide. The outside air that is entering a building must meet U.S. EPA National Primary Standards Air Quality is short you have to clean or it must be filtered properly.
In conclusion let dry clean outdoor air in homes and commercial buildings can help dilute and flush out indoor pollutants.
Carbon Monoxide
WARNING: Carbon monoxide can rob your quick ability of blood to properly absorb oxygen so it can be deadly. If carbon monoxide levels in your home are dangerously high, the emergency measures such as immediate evacuation may be required. Although additional research slightly raised by a qualified majority, licensed, specialist is recommended and appropriate repairs or other measures may be necessary. The main cause of deaths from carbon monoxide poisoning in homes is automobile exhaust escaping garage, however improper combustion of fuel in gas appliances, improper ventilation of combustion gases outside exchangers, and cracked heat are also important sources of carbon monoxide exposure.
"At low concentrations health effects are fatigue in healthy and pain chest in people with heart disease. At high concentrations causes vision problems and coordination problems, headaches, dizziness, confusion, nausea. It can cause flu-like symptoms that disappeared after leaving home. Carbon monoxide is fatal at very high concentrations.
The average levels of 0.5 in homes without gas stoves to 5 ppm.
Levels near properly adjusted gas stoves are 5 to 15 ppm.
About poorly adjusted stoves 30 ppm or higher. "Information above is epa.gov / iaq / co.html
If you have an attached garage or any other gas appliances or devices in your building or home have it checked for carbon monoxide carbon. Make sure gas appliances are working properly and properly vented to the outside.
VOC
Volatile compounds Organic also known as volatile organic compounds are common indoor pollutants composed of organic chemicals that evaporate into the air easily, often cause chemical odors, respiratory irritation, headache, and indoor air quality related to other complaints. At certain high levels can be dangerous. These chemicals are released by paints, paint thinners, varnishes, new carpets, new cabinets and furniture panels containing particles, cleaning products, air fresheners, fuel gas, improperly vented combustion devices, machines, photocopiers, model, and many other sources. Refrain from excessive use of household products containing chemicals.
Purchase paints and new carpets with low emissions of VOCs. Solid wood cabinets and furniture contain fewer volatile organic compounds composed of particulate materials table type. When using chemicals or When installing new carpet, paint, cabinets and other furnishings let the property air out in a safe and reasonable. healthy buildings usually contain less of 1 ppm or even less than 5 ppm.
Formaldehyde
Formaldehyde is a common volatile organic compounds resulting in a lot of problems of indoor air quality, is at the glues used in the manufacture of particle board, veneer, wood furniture, plywood, and other wood products.
Also in some spray-on insulating foams. These resins slowly give off formaldehyde over time. Formaldehyde is one of the most common air pollutants indoors. At concentrations above 0.1 ppm in air, formaldehyde can irritate the eyes and mucous membranes, resulting in watery eyes. If inhaled, formaldehyde at this concentration may cause headaches, a burning sensation in the throat and difficulty breathing, as well as triggering asthma symptoms.
The previous recommendations made in relation to other volatile organic compounds also applies to formaldehyde.
Sewer Gas
Hydrogen sulfide is the gas that produces rotten egg or sulfur like odors in well water systems sewage, rotten eggs, and other areas where water and organic compounds have a lack of oxygen. Hydrogen sulfide odors may lead to allegations of ill- odors and eye and throat irritation cough and shortness of breath. According to wikipedia ".0047 ppm is the recognition threshold, the concentration in which 50% of humans can detect the characteristic rotten egg smell of hydrogen sulphide. "10 to 15 ppm is the limit of the concentration of eye irritation.
drainage pipes have shaped curve letter U that traps water, you have seen this under your sinks, and this trapped water is intended to maintain sewer gas backup of the sewer system and at home. Make sure drains and basement drains, sinks, toilets and even contain some water, etc. If gas water evaporates from a drains p trap then sewer is backed up on the building. In the properties vacant for anaerobic bacteria can invade your water heater and produce sulfur gas odors in drinking water on their properties and similar water bacteria can invade your system as well water and create strong sulfur odors. The latter two conditions are annoying but are generally considered harmless and can be repaired by a plumber or service company of water.
No2
Nitrogen dioxide is made up of nitrogen and oxygen atoms, incomplete combustion in vehicles or equipment gas can create this pollutant and improper venting of combustion gases of these gas appliances, loading docks and parking garages, can result in gas entering the indoor environment. Nitrogen dioxide is a respiratory tract irritation. If you have any gas appliances or devices in your building or home have the property checked for nitrogen dioxide, carbon monoxide and other combustion gases. Make sure gas appliances are working correctly and properly ventilated to the outside.
O3
Ozone is a fresh smelling oxygen molecule composed of 3 atoms of oxygen, oxygen we breathe is composed of only two molecules of oxygen. In blocks of ozone in the upper atmosphere of harmful UV light thus protecting organisms living below in the tropospheric ozone is an air pollutant that can have harmful effects on our respiratory system, in fact, ozone pollution is a form of smog. Asthmatics are especially at risk from the effects of ozone exposure.
Despite claims of safe levels of fresh smelling ozone issued by ozone-producing machines, some ozone machines have been found to produce ozone at levels that can cause respiratory irritation in some people. True that ozone can break down smoke, odors and other air pollutants, but the decomposition product, follow the most basic laws of physics and thus do not disappear of existence, but these products have end up in the air where some of them may serve as irritants to sensitive individuals.
– According to the EPA some health effects from excessive exposure to ozone are:
– The decrease in lung function
– Worsening of asthma
– Sore throat and cough
– Chest pain and shortness of breath
– Inflammation of lung tissue
– Increased susceptibility to respiratory infection

Radon
final list but not less than 10 casualties or Indoor Air Quality (IAQ) problems is radon, a colorless, odorless gas that makes its way into buildings through cracks in the foundations. If a building is negative pressure after the negative pressure can cause radon to be actively absorbed by the building. Radon is unknown in some areas like southern Florida and in other areas such as New England, radon is common. Radon is a carcinogen causing agent or cancer. A Often people living with radon have no idea that there is a problem until it is too late. Even in non smokers radon causes lung cancer. If you know of a home where a non-smoker who developed lung cancer should suggest that the home or former residence of the victim radon test. According to EPA and the Surgeon General of the radon is responsible for 15,000 deaths a year. About the Author
