Download or read book Formaldehyde and Acetaldehyde Exposure Mitigation in US Residences written by and published by . This book was released on 2014 with total page 33 pages. Available in PDF, EPUB and Kindle. Book excerpt: Measurements were taken in new US residences to assess the extent to which ventilation and source control can mitigate formaldehyde exposure. Increasing ventilation consistently lowered indoor formaldehyde concentrations. However, at a reference air exchange rate of 0.35 h-1, increasing ventilation was up to 60% less effective than would be predicted if the emission rate were constant. This is consistent with formaldehyde emission rates decreasing as air concentrations increase, as observed in chamber studies. In contrast, measurements suggest acetaldehyde emission was independent of ventilation rate. To evaluate the effectiveness of source control, formaldehyde concentrations were measured in Leadership in Energy and Environmental Design (LEED) certified/Indoor airPLUS homes constructed with materials certified to have low emission rates of volatile organic compounds (VOC). At a reference air exchange rate of 0.35 h-1, and adjusting for home age, temperature and relative humidity, formaldehyde concentrations in homes built with low-VOC materials were 42% lower on average than in reference new homes with conventional building materials. Without adjustment, concentrations were 27% lower in the low-VOC homes. The mean and standard deviation of formaldehyde concentration were 33 [mu]g m-3 and 22 [mu]g m-3 for low-VOC homes and 45 [mu]g m-3 and 30 [mu]g m-3 for conventional.

Available in PDF, EPUB and Kindle. Book excerpt: Formaldehyde is virtually ubiquitous in the modern environment due to its cost-effective nature, its use in resin formation, and its preservative properties. Though formaldehyde is necessary for many products and processes important to the world’s economy, this economic dependence on formaldehyde comes at a cost to public health. Growth and consequent industrialization rely heavily on formaldehyde use. New buildings—residences, public places, and offices—are not only built with timber preserved by formaldehyde, but they are also furnished with wood, wool, and textile products that contain formaldehyde. The general population faces environmental exposure from indoor and outdoor air pollution, food, and even medicine. Scientific inquiry into formaldehyde exposure has grown in response. This book consolidates the new and established body of formaldehyde research in the scholarly community, focusing on exposure, genotoxicity, and adverse health outcomes. Through this resource, we hope to increase awareness of the broad range of health effects posed by formaldehyde exposure, and to encourage interdisciplinary interest, as well as research, into this pervasive compound—especially in the United States and China, where formaldehyde production and usage is high. This book will be useful to researchers of environmental and occupational exposure, students, and government regulators and anyone exposed to formaldehyde in the workplace and/or at home.

Download or read book Formaldehyde written by R. Liteplo and published by . This book was released on 2002 with total page 90 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book evaluates the risks to human health and the environment of formaldehyde. Formaldehyde is a colorless, highly reactive gas with a pungent, irritating odor at room temperature. Sensory irritation of the eyes and respiratory tract by formaldehyde has been observed consistently in clinical studies and epidemiological surveys in occupational and residential environments. Formaldehyde is produced commercially and used predominantly in the synthesis of resins, but the largest direct human source of formaldehyde in the environment is the combustion of organic materials. Releases from industrial processes are considerably less.
Download or read book Formaldehyde as an Indoor Air Quality Metric for Homes written by Mark Cree Jackson and published by . This book was released on 2017 with total page 996 pages. Available in PDF, EPUB and Kindle. Book excerpt: The renewed emphasis on energy conservation in the building sector has resulted in advances in residential building envelope design and construction that have led to ever tighter homes, lower energy consumption and reduced emissions of greenhouse gases. To keep pace with these advances, indoor air quality (IAQ) engineers are seeking ways to cost effectively achieve aldehyde, particularly formaldehyde (HCHO), and volatile organic compound (VOC) concentrations that meet government reference exposure limits (RELs). This work investigates four key concepts: (1) the efficacy of using HCHO as a surrogate for the impact of all aldehydes and VOCs on IAQ, (2) energy use/cost, compared with baseline energy used to achieve ASHRAE 62.2-2016 ventilation rates, required to attain desired RELs, (3) Disability Adjusted Life Year (DALY) benefits/value of reaching desired RELs and, (4) energy savings/value, identification and initial testing of a real-time HCHO monitor/controller to control variable speed ventilation and gas-phase filtration to achieve desired HCHO concentrations. This work is expected to inform decision makers and potentially be incorporated into several national standards and building programs such as ASHRAE 62.2, RESNET HERS® ratings, the U.S. EPA’s EnergyPlus and U.S. DOE’s Building America programs.

Download or read book Climate Change the Indoor Environment and Health written by Institute of Medicine and published by National Academies Press. This book was released on 2011-10-01 with total page 286 pages. Available in PDF, EPUB and Kindle. Book excerpt: The indoor environment affects occupants' health and comfort. Poor environmental conditions and indoor contaminants are estimated to cost the U.S. economy tens of billions of dollars a year in exacerbation of illnesses like asthma, allergic symptoms, and subsequent lost productivity. Climate change has the potential to affect the indoor environment because conditions inside buildings are influenced by conditions outside them. Climate Change, the Indoor Environment, and Health addresses the impacts that climate change may have on the indoor environment and the resulting health effects. It finds that steps taken to mitigate climate change may cause or exacerbate harmful indoor environmental conditions. The book discusses the role the Environmental Protection Agency (EPA) should take in informing the public, health professionals, and those in the building industry about potential risks and what can be done to address them. The study also recommends that building codes account for climate change projections; that federal agencies join to develop or refine protocols and testing standards for evaluating emissions from materials, furnishings, and appliances used in buildings; and that building weatherization efforts include consideration of health effects. Climate Change, the Indoor Environment, and Health is written primarily for the EPA and other federal agencies, organizations, and researchers with interests in public health; the environment; building design, construction, and operation; and climate issues.

Available in PDF, EPUB and Kindle. Book excerpt: This book presents WHO guidelines for the protection of public health from risks due to a number of chemicals commonly present in indoor air. The substances considered in this review, i.e. benzene, carbon monoxide, formaldehyde, naphthalene, nitrogen dioxide, polycyclic aromatic hydrocarbons (especially benzo[a]pyrene), radon, trichloroethylene and tetrachloroethylene, have indoor sources, are known in respect of their hazardousness to health and are often found indoors in concentrations of health concern. The guidelines are targeted at public health professionals involved in preventing health risks of environmental exposures, as well as specialists and authorities involved in the design and use of buildings, indoor materials and products. They provide a scientific basis for legally enforceable standards.
