Indoor air pollution and home contaminants term paper

The linear no-threshold model of radiogenic cancer is false. This linear "dose-response" assumption was made even though there was considerable uncertainty for the validity of the extrapolation at lower levels of SLRDs.

Additionally, it was assumed that houses with high exchange rates would have lower radon concentrations than houses with few air changes per hour.

Chapter 5: Indoor Air Pollutants and Toxic Materials

Pollutant Sources There are many sources of indoor air pollution. The left-most column indicates the 7 studies that are selected for this research. We have to remember that there are degrees of exposure, ranging from massive doses seen in miners who also inhale other contaminants, to minimal, negligible doses seen in residential scenarios.

The granodiorite has been shown in some cases to be the sole source of radon in a structure. Yes, but only in part. Wood stoves and fireplaces should only be used to burn properly sized and aged wood, since other types of fuel may emit toxic compounds. Unfortunately there is no universal definition of acceptable air pollution.

Indoor Air Pollution Paper

The body will absorb, ingest, or inhale the exposed pollutant which causes illness. The latter term is reserved for situations in which signs and symptoms of diagnosable illness are identified and can be attributed directly to specific airborne building contaminants.

Like many other household products and furnishings, new carpet can be a source of chemical emissions. It is the emission of high-energy alpha particles during the radon decay process that increases the risk of lung cancer. Air cleaning alone cannot adequately remove all pollutants typically found in indoor air.

In fact, the linear model has long been known to be invalid 26and the EPA has long recognized that the linear model is invalid, but decided to use it anyway. Manufacturers of particular products may also be able to supply information. However, an ER of 0.

Studies have been done to ascertain both the causes of air quality problems and their possible solutions. There are few conclusive studies on the subject, whether relating to public buildings and offices or private dwellings. A person who is exposed to high concentration of pollutants in an indoor setting may find that they feel discomfort, irritation, illness, and may even die as a result of the pollutant.

Indoor Air Quality&nbspTerm Paper

Hire Writer In with the oil embargo came the rise of energy conserving practices and devices. Dust can also be found in refrigerator coils and allows for growth of micro flora. Indoor pollutants must be handled in a similar fashion.

A World Health Organization report suggested that as many as 30 percent of new and remodeled buildings worldwide may generate excessive complaints related to indoor air quality National Heart Lung and Blood Institute.

Asthma is a chronic long-term lung disease that inflames and narrows the airways. If there is no forced ventilation with a ventilator this value is difficult to determine, although it is considered to vary between 0.

The gamma radiation is similar to X-rays and has an even lower probability of being stopped. Contaminants from the outside can contribute to human exposure both directly and indirectly if they get inside a building. Even new carpets and furniture must be aired out by the manufacturer or distributor prior to delivery in order to eliminate the many toxins that are used in the manufacturing and storing of these possessions.

The process is frequently of a repetitive nature, so that the study has to be started again several times, using more sophisticated techniques on each occasion.

The only human data available for predicting the risks to the public are studies examining the health effects of exposure to radon and its progeny in underground miners. Criteria Air Pollutants. The Clean Air Act regulates six common air pollutants: particle pollution (particulate matter), ground-level ozone, carbon monoxide, sulfur oxides, nitrogen oxides, and lead.

Indoor Air Pollution: An Introduction for Health Professionals

This module provides the fundamentals to understanding indoor air quality. It provides a rudimentary framework for understanding how indoor and outdoor sources of pollution affect the indoor air quality.

Air pollution can have short- and long-term health effects. Asthma from air pollution can have short- and long-term effects.

Short-term effects of asthma are irritation to the eyes, nose, and throat. Long-term reactions to air pollution can include upper respiratory infections such as bronchitis and pneumonia. Indoor air quality (IAQ) is a term which refers to the air quality within and around buildings and structures, especially as it relates to the health and comfort of building mobile-concrete-batching-plant.com can be affected by gases (including carbon monoxide, radon, volatile organic compounds), particulates, microbial contaminants (mold, bacteria), or any mass or energy stressor that can induce adverse health.
