(1 RC) - These specifications were developed by the U.S. Environmental Protection Agency to recognize new homes equipped with a comprehensive set of Indoor Air Quality features. They were developed with significant input from stakeholders, based on best available science and information about risks associated with IAQ problems, and balanced with practical issues of cost, builder production process compatibility, and verifiability… (EPA, Feb 2008)
This HHE conducted by the CDC and NIOSH explores the ventilation system at Blue Cross and Blue Shield of MI in Grand Rapids MI. Workers at the auto industry were experiencing flu like symptoms which they believed were due to inadequate air ducts.
(4 RC) - Possible exposure pathways associated with this site include inhalation of contaminated indoor air as well as dermal exposure to and incidental ingestion of contaminated soil, sediment, and surface water. The indoor air pathway was selected for evaluation first because of the potential for nearby residents to be exposed to volatile chemicals in their homes throughout the year… (ATSDR, Sept 2014)
(.50 RC) - The U.S. EPA collected six sub-slab samples and six indoor air samples at Holden Elementary School in July 2011. The primary contaminants of concern at the site are components of the petroleum-based product gasoline and include benzene, hexane, and trimethylbenzenes. In addition, chlorofluorocarbon products were identified… (ASTDR, Apr 2012)
(1 RC) - In response to a request from a health care provider about a patient and husband with elevated mercury levels in blood and urine and related health symptoms, the Wisconsin Division of Public Health investigated for mercury contamination in their west-central Wisconsin house. DPH inspected the house and tested for mercury vapors and found high mercury levels associated with adverse health effects. The U.S. Environmental Protection Agency cleaned up elemental mercury at the affected house… (ASTDR, July 2009)
(1 RC) - Milwaukee Public Schools requested assistance from the Wisconsin Department of Health Services, to evaluate potential health concerns associated with mercury-catalyzed polyurethane flooring in the gymnasium of South Division High School, Milwaukee, Wisconsin. The intent of this health consultation is to characterize and assess the human health implications of elemental mercury vapor levels in the air of the SDHS gym… (ASTDR, Dec 2010)
(2 RC) - A soil gas data screening indicates that 1,4 dioxane is a concern for vapor intrusion in a WI building occupied by workers and children. As 1,4dioxane is highly soluble in water, it is possible that its presence in soil gas samples indicates the leading edge of the groundwater plume may be approaching the building. A complete indoor air investigation of the WI is necessary to evaluate the potential for current exposures… (ASTDR)
This Health Hazard Evaluation (HHE), conducted by the CDC and NIOSH, investigates a Ronald McDonald house in Durham North Carolina in response to employees experiencing diarrhea, stomach cramps, vomiting, dizziness, weakness, and fatigue.
(3 RC) - What can communities do to reduce their exposure to wildfire smoke indoors? What interventions are effective for reducing wildland fire smoke exposures and risks? What science is available to support recommendations for communities to develop cleaner air spaces in larger buildings (e.g., schools, community centers)…(EPA, April 2021)
(1 RC) - Asthma has reached epidemic proportions in the United States, affecting millions of people of all ages and races. An average of one out of every 10 school-age children now has asthma, and the percentage of children with asthma is rising more rapidly in preschool-age children than in any other age group. Asthma is a leading cause of school absenteeism due to a chronic condition, accounting for nearly 13 million missed school days per year… (EPA, Aug 2010)
(3 RC) - Observations show that warming of the climate is unequivocal. The global warming observed over the past 50 years is due primarily to human-induced emissions of heat-trapping gases. These emissions come mainly from the burning of fossil fuels (coal, oil, and gas), with important contributions from the clearing of forests, agricultural practices, and other activities… (EPA)
(3 RC) - Conservation-minded building codes have the potential to reduce naturally occurring air exchange for buildings by tightening the envelope and reducing pressurization of unconditioned spaces (e.g. duct sealing). Indoor moisture, altered airflows, lowered air exchange all have the potential for increasing occupant risk of exposures to indoor generated contaminants..… (EPA, Sep 2009)
(1 RC) - The draft proposed sampling plan provides an overview of how buildings (residential, office, and public) south of Houston Street, in Manhattan, would be sampled to determine if any remaining WTC-related contamination is present. As proposed, only dust samples would be taken from buildings made available by the owners or managers. Samples would be taken from locations where exposures are likely to occur, such as in elevated horizontal surfaces.… (ATSDR, Mar 2005)
(2 RC) - Schlage Lock Company, located in Security, Colorado, discovered that the groundwater beneath their manufacturing facility was contaminated with the chemical tetrachloroethylene, which is also known as perchloroethylene (PCE). Schlage utilized the solvent as a metal cleaner and degreaser during the production of door locks and related hardware… (ATSDR, Nov 2006)
