Indoor air quality thesis

In addition, residents should be alert to the emergence of signs of inadequate ventilation, such as stuffy air, moisture condensation on cold surfaces, or Indoor air quality thesis and mildew growth. Health effects from indoor air pollutants may be experienced soon after exposure or, possibly, years later.

Fuel-buring combustion appliances Building materials and furnishings as diverse as: Inexpensive devices are available for measuring radon. Pollutant Sources There are many sources of indoor air pollution. However, measures such as installing storm windows, weather stripping, caulking, and blown-in wall insulation can reduce the amount of outdoor air infiltrating into a home.

Signs that can indicate your home may not have enough ventilation include: Although the presence of such sources does not necessarily mean that you have an indoor air quality problem, being aware of the type and number of potential sources is an important step toward assessing the air quality in your home.

EPA provides guidance as to risks associated with different levels of exposure and when the public should consider corrective action. Another way to judge whether your home has or could develop indoor air problems is to identify potential sources of indoor air pollution.

In some cases, whether a person reacts to a pollutant depends on individual sensitivity, which varies tremendously from person to person.

These factors include poor ventilation lack of outside airproblems controlling temperature, high or low humidity, recent remodeling, and other activities in or near a building that can affect the fresh air coming into the building.

Additional weatherization measures should not be undertaken until these problems have been corrected. Deteriorated asbestos-containing insulation Newly installed flooring, upholstery or carpet Cabinetry or Indoor air quality thesis made of certain pressed wood products Products for household cleaning and maintenance, personal care, or hobbies Central heating and cooling systems and humidification devices Excess moisture.

These include irritation of the eyes, nose, and throat, headaches, dizziness, and fatigue. Before monitoring your home for pollutants besides radon, consult your state or local health department or professionals who have experience in solving indoor air quality problems in non-industrial buildings.

Weatherization generally does not cause indoor air problems by adding new pollutants to the air. The following States have Indoor Air regulations: While pollutants commonly found in indoor air can cause many harmful effects, there is considerable uncertainty about what concentrations or periods of exposure are necessary to produce specific health problems.

Many factors affect IAQ.

Introduction to Indoor Air Quality

Identifying Problems in the Indoor Environments Long-Term Effects Other health effects may show up either years after exposure has occurred or only after long or repeated periods of exposure.

Inadequate ventilation can increase indoor pollutant levels by not bringing in enough outdoor air to dilute emissions from indoor sources and by not carrying indoor air pollutants out of the area.

There are specific mitigation techniques that have proven effective in reducing levels of radon in the home. While weatherization is underway, however, steps should also be taken to minimize pollution from sources inside the home.

People also react very differently to exposure to indoor air pollutants.

Identifying Problems in the Indoor Environments

Some effects may be made worse by an inadequate supply of outdoor air coming indoors or from the heating, cooling or humidity conditions prevalent indoors.

High temperature and humidity levels can also increase concentrations of some pollutants. Weatherizing Your Home Some health effects can be useful indicators of an indoor air quality problem, especially if they appear after a person moves to a new residence, remodels or refurnishes a home, or treats a home with pesticides.

It is prudent to try to improve the indoor air quality in your home even if symptoms are not noticeable.

For this reason, it is important to pay attention to the time and place symptoms occur. Such immediate effects are usually short-term and treatable. Certain immediate effects are similar to those from colds or other viral diseases, so it is often difficult to determine if the symptoms are a result of exposure to indoor air pollution.

Top of Page Measuring Radon Levels The federal government recommends that you measure the level of radon in your home. If the symptoms fade or go away when a person is away from the area, for example, an effort should be made to identify indoor air sources that may be possible causes.

The right ventilation and building care can prevent and fix IAQ problems. These effects, which include some respiratory diseases, heart disease and cancer, can be severely debilitating or fatal.

Without measurements there is no way to tell whether radon is present because it is a colorless, odorless, radioactive gas. If you think that you have symptoms that may be related to your home environment, discuss them with your doctor or your local health department to see if they could be caused by indoor air pollution.

Finally, look for signs of problems with the ventilation in your home. Soon after exposure to some indoor air pollutants, symptoms of some diseases such as asthma may show up, be aggravated or worsened.1 Na Li Indoor Air Quality (IAQ) Using Temporal Data and GIS to Visualize IAQ in Campus Buildings Bachelor’s Thesis Environmental Engineering.
