(3 RC) - The Health Hazard Evaluation Program received a request from employees at a police department in Ohio. The request concerned lead exposures in and around the firing range, a history of water intrusion and mold growth on the ceiling tiles in the juvenile office, and lack of ventilation in the property room where illicit drugs were stored. We made two site visits to the police department to evaluate exposures, work conditions, and employee health concerns… (NIOSH HEE, July 2013)
(4 RC) - In November 2009, NIOSH received an HHE request from a police department in Kentucky. The request concerned possible health effects from working inside a vault used to store drug evidence, including marijuana, cocaine, methamphetamine, and oxycodone. We conducted evaluations in December 2009 and July 2010… (NIOSH, July 2011)
(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)
(4 RC) - Indoor air contains a wide variety of chemical compounds. Some of these compounds, including volatile organic compounds (VOCs), originate mainly from indoor sources such as paints, building products, furnishings, glues, varnishes, and consumer and household products. Other pollutants, such as nitrogen dioxide (NO2) and ozone (O3), are classical pollutants of outdoor air that penetrate indoor environments in different ways in additional to releases from indoor sources… (WHO, Jan 2020)
(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)
(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) - 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)
(3 RC) - This report addresses two questions. First, are air formaldehyde levels in closed, unventilated trailers high enough to be associated with health effects in humans? Second, can simple measures such as running air conditioning or opening windows lower the levels of formaldehyde? Accordingly, the data were generated by conducting air sampling for formaldehyde in new, unoccupied trailers under three specific conditions.… (ATSDR, Oct 2007)
(2 RC) - This health consultation evaluates health risks from exposure to tetrachloroethylene and trichloroethylene associated with the operation and/or contamination at Pacific Cleaners. The owners of an adjacent health food store, Randy’s Nutrition Center, and the Thurston County Public Health and Social Services Department had raised concerns regarding potential exposure to PCE and TCE in indoor air.… (ATSDR, Mar 2005)
(1 RC) - The indoor air monitoring for homes surrounding Hill AFB began in 2003 and currently continues. Both homes residing directly over the plume as well as homes outside of the plume boundaries were sampled. During the routine sampling, indoor air samples were collected and analyzed for VOCs. One of the contaminants routinely detected in indoor air samples is 1,2-DCA; it has been detected in approximately 90 homes in Layton.… (ATSDR, May 2009)
(1 RC) - On May 24, 2016, CO2 alarms outside the school went off, prompting an evacuation of students and staff. Air monitoring and investigation began two days later on May 26. ATSDR recommends that the building not be reoccupied until thorough investigation and sampling demonstrate no potential health hazards from building indoor air. … (ATSDR, Sept 2006)
(2 RC) - The Environmental Toxicology Program (ETP) at Oregon State Public Health issued a public health advisory to all school districts in Oregon. The advisory was prompted by the release of two public health consultations from Ohio and Michigan related to flooring manufactured by the 3M Corporation from the early 1960’s to 1980. According to 3M, mercury was used as a catalyst when mixing the polymer to form the floor… (ATSDR, July 2006)
(4 RC) - The Oregon Public Health Division Environmental Health Assessment Program (EHAP) was asked by the Salem-Keizer School District to conduct this Health Consultation (HC). The purpose of this HC is to evaluate the public health risk for children who may have come into contact with contaminants found on several school buses in the Salem-Keizer School District. Following a fire that destroyed and/or damaged several school buses… (ATSDR, Feb 2009)
(2 RC) - The owners of Farmer’s Insurance expressed concerns about the potential for exposure to dry-cleaning chemicals in indoor air from subsurface and aboveground sources at Eastside Laundry. To address these concerns, DOH and TCHD conducted indoor air sampling at Eastside Laundry and two adjacent businesses (Farmer’s Insurance and Roy’s) in the winter of 2002. This sampling event revealed PCE levels in indoor air… (ATSDR, Sept 2007)
(2 RC) - Arizona Department of Health Services (ADHS) was requested to provide assistance in addressing concerns about air quality at Corona del Sol High School in Tempe, AZ. This health consultation follows up a previous report produced by ADHS in May 2008 and addresses previously unaddressed issues regarding possible exposure to and potential health risks from formaldehyde and volatile organic compounds (VOCs) in the indoor air at the school… (ATSDR, Sept 2008)
(2 RC) - Samples had an asbestos content greater than 1%, which is the regulatory level used to define an ACM. All three samples were found to contain 2-5% chrysotile asbestos. After receiving these sample results, GRIC OSH recommended that the Gila Crossing Presbyterian Church be closed until the ACM could be properly remediated… (ATSDR, Mar 2005)
(4 RC) - Bioaerosols are airborne particles that originate from biological sources including animals, plants, fungi, bacteria, protozoa, and viruses. Examples of bioaerosols encountered in occupational environments include plant pollen, algae, fungal spores, bacteria such as actinomycetes, droplets produced during coughing and sneezing that may contain bacteria and viruses, dust containing insect excreta, animal dander, and fragments derived from each of these sources. … (NIOSH, Feb 2020)
(3 RC) - The need for aerosol sampling is driven by research or regulatory needs to understand or quantify the properties of airborne particles in the workplace or ambient environments. The property of most common interest is the airborne concentration of particulate mass defined as the aerosol mass per unit volume of air … (NIOSH, Feb 2020)
