Ventilation can control indoor humidity and airborne contaminants, both of which either contribute to or act as health hazards. The American Society of Heating, Refrigerating, and Air Conditioning Engineers (ASHRAE) and several states (Minnesota, Washington, and Vermont) have ventilation standards designed to ensure acceptable indoor air quality. High indoor humidity can spur mold growth. High humidity may result from poor construction/rehabilitation, site design that does not properly manage water, and/or inadequate air exchange. A reasonable target for relative humidity is 30-60 percent. A low cost hygrometer, available at hardware stores, can be used to measure relative humidity. In cool climates, inadequate ventilation in the winter can contribute to excessive moisture and humidity because normal activities create moisture (cooking, bathing, breathing), and there is insufficient natural ventilation (opening windows) or mechanical ventilation (fans, exhaust systems) to remove the moisture. In warmer climates, the heating, ventilation, and air conditioning (HVAC) system can pull warmer, humid air inside. In this case, the ventilation system may help create indoor humidity problems unless the system also dehumidifies the air.

Home About ELC Site Map Contact Us ... Food Indoor Air Pollution Concern about air quality has traditionally focused on outside air even though people generally spend more of their time indoors. Outdoor air pollutants tend to become dispersed and diluted by wind, rain, and other natural processes. Indoor pollutants, however, are shielded from nature's cleaning agents and can become quite concentrated. Improvements in residential insulation over the last twenty-five years have contributed to energy conservation, but these advances have not been followed by similar improvements in ventilation. Indoor air pollution comes from a variety of man-made and natural sources including combustion, cleaning agents, and a variety of other substances such as paints, residual chemicals in carpets, and adhesives. Improper ventilation has led to a number of accidental carbon monoxide poisonings. In many developing countries, wood, dung, and residual crop products are used for cooking and heat in many households, generating smoke and soot that contributes to respiratory illnesses. Natural pollutants, such as mold, mildew, pet dander, and bacteria can also pose a threat to health. Recently, studies have suggested that the increase in incidence of childhood asthma is connected to indoor pollutants such as dust mites and cockroach droppings. Natural contaminants pose the greatest risk when they are dispersed through heating, air conditioning, and ventilation systems. Probably one of the most well known cases of such contamination occurred during an American Legion convention in 1976. The Legionnaires were exposed to an airborne bacteria that circulated from a hotel air conditioning system where they had been staying. Twenty-nine people died and over one-hundred-eighty became ill as a result of the condition, later known as

Home Site Map Gardening Advice Top Houseplants for Improving Indoor Air Quality Top Houseplants for Improving Indoor Air Quality In the late 1980s, a study by NASA and the Associated Landscape Contractors of America (ALCA) resulted in excellent news for homeowners and office workers everywhere. The study concluded that common houseplants such as bamboo palms and spider plants not only make indoor spaces more attractive, they also help to purify the air! The study was conducted by Dr. B.C. Wolverton, Anne Johnson, and Keith Bounds in 1989. While it was originally intended to find ways to purify the air for extended stays in orbiting space stations, the study proved to have implications on Earth as well. Newer homes and buildings, designed for energy efficiency, are often tightly sealed to avoid energy loss from heating and air conditioning systems. Moreover, synthetic building materials used in modern construction have been found to produce potential pollutants that remain trapped in these unventilated buildings. The trapped pollutants result in what is often called the Sick Building Syndrome. With our ultra modern homes and offices that are virtually sealed off from the outside environment, this study is just as important now as when it was first published.

Rural St. Indianapolis, IN 46205 What is the Indoor Air Quality Program? The main focus of the Indoor Air Quality Program is to reduce exposure to health hazards in homes and businesses. This program offers a variety of inspection services aimed at identifying and eliminating various contaminants, including asbestos, radon and other indoor air health hazards. Significant Achievements: The indoor air quality staff joined a local team of professionals to address the incidence of pediatric asthma. The indoor air quality staff identify and reduce the environmental triggers which lead to the onset of pediatric asthma. Indoor air specialists concentrate their inspection, investigation and educational efforts in the homes and schools using both enforcement of codes and health education to control identified environmental triggers. Indoor Air specialists also works closely with the Environmental Protection Agency (EPA) and the Indiana State Department of Health (ISDH) to sponsor workshops for local school systems on how to use the "Tools for Schools" kit designed to assess indoor air risk factors. Reducing exposure to carbon monoxide has continued to be a major activity of the indoor air quality staff. A coalition of public and private partners provides education to the general public and specific trade groups such as heating contractors (repair men). Coalition members are trained about the dangers of carbon monoxide exposure and about increased awareness of the resources available to reduce the public's risk. The coalition is working with the fire departments to ensure identified problems are corrected.

LOG IN CALENDAR MEMBERSHIP BIBLIOGRAPHY ... EBN ARTICLES Feature from Environmental Building News November/December 1994 Carpeting, Indoor Air Quality, and the Environment Health Concerns So What DO We Know? After receiving several hundred complaints about possible carpet-related health effects, the U.S. Consumer Product Safety Commission (CPSC) commissioned a study by Hodgson and others at LBL of chemical emissions from carpets. Dozens of chemicals released from carpets were observed and 31 were positively identified. Emission levels of these chemicals were then compared to existing data about their health effects. As the measured emissions were considered peak values to which people would be exposed for only a few hours or days, they were compared only to known short-term health effects. No attempt was made to assess the possible effect of chronic or long-term exposure. As measured, none of the chemicals approached levels known to be hazardous upon short-term exposure. Of the chemicals released, most notable are styrene and 4-PC, both of which come from the SB latex backing that is used on 95% of carpets. Styrene is a known toxin and suspected carcinogen. 4-PC has not been shown to be toxic, but it has a detectable odor even at levels below one part per billion and is the chemical most responsible for the distinctive smell associated with new carpets. It is also less volatile than many of the other chemicals measured, so it continues to be emitted at measurable levels for a longer time.

REDUCING INDOOR AIR POLLUTION Indoor Air Pollution: A Serious Public Health Problem We spend most of our time indoors surrounded by sources of air pollution: consumer products, gas appliances, building materials, cigarettes, and furniture can all contribute to the problem. Yet, the toxic emissions from many of these sources are not controlled or are only partially controlled by federal, state, or local laws. This brochure will tell you about indoor air pollution and what the California Air Resources Board (ARB) is doing about it. Evaluating the Risk In a 1987 study, the U.S. Environmental Protection Agency (U.S. EPA) ranked indoor air pollution fourth in cancer risk among the 13 top environmental problems analyzed. Indoor radon ranked first. What factors contribute to the high risk from indoor air pollution? First, people spend most of their time indoors. A recent ARB-sponsored study found that Californians spend an average of 87 percent of their 24-hour day indoors. If pollutants are present indoors, people will almost certainly inhale them.
