Moreover, losing them will lead directly or indirectly to incalculable economic losses. We have come to appreciate the importance of our environment. Much has been said and written about environmental problems with nuclear power, and they will be discussed at great length in this book. They probably exceed those of any other human activity.

Do symptoms resolve when the individual is not in the building? Do symptoms recur seasonally heating, cooling? Have co-workers, peers noted similar complaints? Remedial Action Appropriate persons -- employer, building owner or manager, building investigation specialist, if necessary state and local government agency medical epidemiologists and other public health officials -- should undertake investigation and analysis of the implicated building, particularly the design and operation of HVAC systems, and correct contributing conditions.

Persistence on the part of individuals and health care consultants may be required to diagnose and remediate the building problems.

Comment The term "sick building syndrome" SBSfirst employed in the s, describes a situation in which reported symptoms among a population of building occupants can be temporally associated with their presence in that building.

Typically, though not always, the structure is an office building. Generally, a spectrum of specific and nonspecific complaints are involved. The key factors are commonality of symptoms and absence of symptoms among building occupants when the individuals are not in the building.

Sick building syndrome should be suspected when a substantial proportion of those spending extended time in a building as in daily employment report or experience acute on-site discomfort.

If is important, however, to distinguish SBS from problems of building related 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.

There has been extensive speculation about the cause or causes of SBS. The ventilation system itself can be a source of irritants.

Interior redesign, such as the rearrangement of offices or installation of partitions, may also interfere with efficient functioning of such systems. Another theory suggests that very low levels of specific pollutants, including some discussed in the preceding pages, may be present and may act synergistically, or at least in combination, to cause health effects.

Humidity may also be a factor: Other contributing elements may include poor lighting and adverse ergonomic conditions, temperature extremes, noise, and psychological stresses that may have both individual and interpersonal impact.

Air Emissions Factors and Quantification

The prevalence of the problem is unknown. 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 In a nationwide, random sampling of U.

When SBS is suspected, the individual physician or other health care provider may need to join forces with others e.

Both are known human carcinogens. Their carcinogenic effects are not immediate but are evident only years, even decades, after prolonged exposure. Asbestos Once widely used in structural fireproofing, asbestos may be found predominantly in heating systems and acoustic insulation, in floor and ceiling tiles, and in shingles in many older houses.

It was formerly used in such consumer products as fireplace gloves, ironing board covers, and certain hair dryers. When asbestos-containing material is damaged or disintegrates with age, microscopic fibers may be dispersed into the air.Chapter 44 - Indoor Air Quality INDOOR AIR QUALITY: INTRODUCTION.

Xavier Guardino Solá. The connection between the use of a building either as a workplace or as a dwelling and the appearance, in certain cases, of discomfort and symptoms that may be the very definition of an illness is a fact that can no longer be disputed.

Bill Text - AB Nonvehicular air pollution: criteria air pollutants and toxic air contaminants. Driving in cars, flying in airplanes, engaging in recreational activities, and being exposed to environmental pollutants all pose varying degrees of risk.

1 An Introduction to Air Pollution 5 pollutants such as ozone, that is quite different from the winter sulfur smog described earlier. This smog has been la beled “Los Angeles” smog, to differentiate.

The most common and widespread danger associated with drinking water is contamination, either directly or indirectly, by sewage, by other wastes, or by human or animal excrement.

A pollutant is a substance or energy introduced into the environment that has undesired effects, or adversely affects the usefulness of a resource.

A pollutant may cause long- or short-term damage by changing the growth rate of plant or animal species, or by interfering with human amenities, comfort, health, or property values. Chapter 2* - Water Quality Requirements * This chapter was prepared by Ute S.
