10 common indoor air quality problems

Mold and water damaged building materials
When the loss is the result in mold growth, which in turn the release of pungent and irritating volatile organic compounds, mold spores and allergens in the air. People with allergies or asthma often have reactions to these contaminants in air, while others may have no reaction. People with compromised immune systems, infection can also molds.Fungal some infections are more a product of poor environmental health of a person found in
Dust mites and dust particles
Air contaminated with excess particles can also cause negative reactions. Some particles cause direct irritation when levels are high. If a person is house dust usually does not have a direct irritation or allergic reactions related. Dust is common because 80% of dead cells from human skin as the powder itself is not seen as a forging invader by your body. When people have allergic reactions to common household dust, dust is not the cause of the problem but allergenic proteins found in the feces of dust mites. Particle counters can be used to measure particulates, particle counters are highly sensitive scientific instruments to use an internal laser to count particles passing through it are a series of predetermined size. Good quality pleated filter in your statement of CA units may help to reduce dust, also use a good quality vacuum cleaner has a HEPA filter. Bad vacuum cleaner to remove dust from your carpets then blow in the face.
Carbon dioxide
The levels of carbon dioxide are often not a direct threat to human health in home and commercial property. The levels of carbon dioxide usually indicates a lack of adequate outdoor air is introduced into the building. Dust, chemicals, body odors and other indoor air pollutants often accumulate, along with carbon dioxide in poorly ventilated buildings and other indoor pollutants are those that give rise to complaints about indoor air quality and health complaints. According to Parat and others "Proper maintenance and management of mechanical ventilation system can reduce the concentrations of indoor bioaerosols by limiting the infiltration of outdoor bioaerosols and diluting the external sources (Parat et al., 1994, 1996).
According to the American Society of Heating, Refrigeration and Air Conditioning Engineers ASHRAE 62-89 in the supply of outdoor air in the building must be at least 20 CFM per person in office and thus help maintain carbon dioxide levels below 1,000 ppm . Latest requirements recommend levels no more than 700 ppm above the levels of carbon dioxide in the atmosphere. Outside air is introduced into a building must comply with the U.S. EPA Primary National Ambient Air Quality Standards is short, must be clean and must be filtered.
In conclusion, I would dry clean outdoor air in homes and commercial buildings can help dilute and remove indoor pollutants.
Carbon Monoxide
CAUTION: The carbon monoxide can quickly steal your Bloods ability to absorb oxygen properly so that it can be fatal. If levels of carbon monoxide in the home are dangerously high, the emergency measures such as immediate evacuation as deemed necessary. Although research is still a bit 'high qualified majority, licensed, specialist is recommended and appropriate repairs or other measures may be needed. The main cause of deaths from carbon monoxide poisoning in homes is automobile exhaust escaping from garages, however improper combustion of fuel in gas appliances, improper ventilation of combustion gases to the outside, and cracked exchanger heat sources of heat are also important exposure to carbon monoxide.
"At low concentrations the health effects are fatigue in healthy people and chest pain in people with heart disease. At higher concentrations cause impaired vision and coordination problems, headaches, dizziness, confusion, nausea. It can cause flu-like symptoms that clear after leaving home. Carbon monoxide is fatal at very high concentrations.
Average levels in homes without gas stoves 0.5-5 ppm.
Levels near properly adjusted gas stoves are 5 to 15 ppm.
About Maladjusted stoves 30 ppm or more. "The 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 house that they checked for carbon monoxide. Ensure that gas appliances are working properly and adequately ventilated to the outside.
VOC
Volatile organic compounds, also known as VOCs are common indoor pollutants composed of organic chemicals that easily evaporate into the air, often cause chemical odors, respiratory irritation, headaches, and other air quality complaints in indoor environments. At certain high levels can be dangerous. These chemicals are released from paints, thinners, varnishes, new carpets, cabinets and furniture containing chipboard, cleaning products and air fresheners, fuel gas, poorly ventilated combustion plants, machines, photocopiers, model, and many more sources. To refrain from excessive use of household products containing chemicals.
Purchase paints and new carpets with low emissions of VOC. Solid wood cabinets and furnishings contain less VOC compound material type of particle board. When using chemicals or when installing new carpet, paint, cabinets and other furniture to allow air to property in a safe and reasonable. Building healthy and generally contain less than 1 ppm or less, 5 ppm.
Formaldehyde
Formaldehyde is a common volatile organic compounds, which translates into 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.
It is also found in some spray-on foam insulation. These resins slowly give off formaldehyde over time. Formaldehyde is one of the most common indoor air pollutants. 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, burning sensation in the throat, and shortness of breath and trigger symptoms of asthma.
The recommendations made earlier than other volatile organic compounds, also applies to formaldehyde.
Sewer gas
Hydrogen sulfide is the gas that produces rotten egg or sulfur smell in water, sewage, rotten eggs, and other areas where water and organic compounds have a shortage of oxygen.
The odors of hydrogen sulfide can lead to complaints of odors and eye and throat irritation, coughing and difficulty breathing. According to Wikipedia ", 0047 ppm is the threshold for recognition, the concentration at which 50% of humans can detect the characteristic rotten egg smell of hydrogen sulphide." 10 to 15 ppm concentration limit irritation eyes.
Drainage pipes have letter u shaped curve that traps water, which saw this under the sink and the water trapped is intended to keep sewer gas to back up the sewer system and into your home. Make sure drains and basement drains, sink drains, and even toilets, etc. contain some 'of water. If the water evaporates from a drain p trap then sewer gas is then copied into the building. Vacant property by anaerobic bacteria can invade the heating of water and produce sulfur gas odors in drinking water, the properties of water and similar bacteria can invade the system of wells and create strong sulfur smell. The last two conditions are annoying but are generally considered harmless and can be repaired by a plumber or water services company.
NO2
Nitrogen dioxide is made up of nitrogen and oxygen atoms, incomplete combustion in vehicles or gas appliances that can create this outburst of pollutants and improper combustion gases, such as gas appliances, loading docks and parking can lead to gas entering the internal environment. Nitrogen dioxide is a respiratory tract irritation. If you have any gas appliances or devices in your building or home have the Checked property of nitrogen dioxide, carbon monoxide and other combustion gases. Ensure that gas appliances are working properly and adequately ventilated to the outside.
O3
Ozone is a molecule of oxygen, fresh fragrance composed of 3 atoms of oxygen, the oxygen we breathe is composed of only two molecules of oxygen. In the upper atmosphere ozone blocks out harmful UV light thus protecting living organisms below ground-level ozone is an air pollutant that can adversely affect our respiratory system in fact ozone is a constitute of smog pollution. Asthma are particularly at risk from the effects of exposure to ozone.
Despite the accusations of security levels, the fresh smell of ozone emitted by ozone producing machines, some machines have found ozone to produce ozone at levels that can cause respiratory irritation in some people. It is true that ozone can reduce the smoke, odors and other air pollutants, but the product continues to violate the most basic laws of physics and therefore it does not exist, but these products end up in the air when some may serve as irritants for sensitive people.

Radon
Last but not least, or a list of 13 victims IAQ (IAQ) problems is radon, a colorless, odorless gas that finds its way into buildings through cracks in foundation. If a building is under negative pressure after the negative pressure can cause radon absorbed actively in the building. Radon is unknown in some areas like South Florida and in other areas, like New England, radon is common. Radon is a carcinogen or cancer-causing agent. Often, people living with radon have no idea that the problem exists only when it is too late. Even in non smokers radon causes lung cancer. If you know of a house where a non-smoker developed lung cancer should be suggested that the home or former residence of radon victim. According to the EPA and the Surgeon General, radon is responsible for 15,000 deaths a year.
