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.

Formaldehyde is ubiquitous in indoor and outdoor air, and everyone is exposed to formaldehyde at some concentration daily. Formaldehyde is used to produce a wide array of products, particularly building materials; it is emitted from many sources, including power plants, cars, gas and wood stoves, and cigarettes; it is a natural product in come foods; and it is naturally present in the human body as a metabolic intermediate. Much research has been conducted on the health effects of exposure to formaldehyde, including effects on the upper airway, where formaldehyde is deposited when inhaled, and effects on tissues distant from the site of initial contact. The U.S. Environmental Protection Agency (EPA) released noncancer and cancer assessments of formaldehyde for its Intergated Risk Information System (IRIS) in 1990 and 1991, respectively. The agency began reassessing formaldehyde in 1998 and released a draft IRIS assessment in June 2010. Given the complexity of the issues and the knowledge that the assessment will be used as the basis of regulatory decisions, EPA asked the National Research Council (NRC) to conduct an independent scientific review of the draft IRIS assessment. In this report, the Committee to Review EPA's Draft IRIS Assessment of Formaldehyde first addresses some general issues associated with the draft IRIS assessment. The committee next focuses on questions concerning specific aspects of the draft assessment, including derivation of the reference concentrations and the cancer unit risk estimates for formaldehyde. The committee closes with recommendations for improving the IRIS assessment of formaldehyde and provides some general comments on the IRIS development process.

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.

A New York Times Notable Book The inspiration for PBS's AMERICAN EXPERIENCE film The Poison Squad. From Pulitzer Prize winner and New York Times-bestselling author Deborah Blum, the dramatic true story of how food was made safe in the United States and the heroes, led by the inimitable Dr. Harvey Washington Wiley, who fought for change By the end of nineteenth century, food was dangerous. Lethal, even. "Milk" might contain formaldehyde, most often used to embalm corpses. Decaying meat was preserved with both salicylic acid, a pharmaceutical chemical, and borax, a compound first identified as a cleaning product. This was not by accident; food manufacturers had rushed to embrace the rise of industrial chemistry, and were knowingly selling harmful products. Unchecked by government regulation, basic safety, or even labelling requirements, they put profit before the health of their customers. By some estimates, in New York City alone, thousands of children were killed by "embalmed milk" every year. Citizens--activists, journalists, scientists, and women's groups--began agitating for change. But even as protective measures were enacted in Europe, American corporations blocked even modest regulations. Then, in 1883, Dr. Harvey Washington Wiley, a chemistry professor from Purdue University, was named chief chemist of the agriculture department, and the agency began methodically investigating food and drink fraud, even conducting shocking human tests on groups of young men who came to be known as, "The Poison Squad." Over the next thirty years, a titanic struggle took place, with the courageous and fascinating Dr. Wiley campaigning indefatigably for food safety and consumer protection. Together with a gallant cast, including the muckraking reporter Upton Sinclair, whose fiction revealed the horrific truth about the Chicago stockyards; Fannie Farmer, then the most famous cookbook author in the country; and Henry J. Heinz, one of the few food producers who actively advocated for pure food, Dr. Wiley changed history. When the landmark 1906 Food and Drug Act was finally passed, it was known across the land, as "Dr. Wiley's Law." Blum brings to life this timeless and hugely satisfying "David and Goliath" tale with righteous verve and style, driving home the moral imperative of confronting corporate greed and government corruption with a bracing clarity, which speaks resoundingly to the enormous social and political challenges we face today.

The International Space Station is a closed and complex environment, so some contamination of its internal atmosphere and water system is expected. To protect space crews from contaminants in potable and hygiene water, the National Aeronautics and Space Administration (NASA) requested that the National Research Council (NRC) provide guidance on how to develop water exposure guidelines and review NASA's development of the exposure guidelines for specific chemicals. NASA selects water contaminants for which spacecraft water exposure guidelines (SWEGs) will be established; this involves identifying toxicity effects relevant to astronauts and calculating exposure concentrations on the basis of those end points. SWEGs are established for exposures of 1, 10, 100, and 1,000 days. This report is the second volume in the series, Spacecraft Water Exposure Guidelines for Selected Chemicals. SWEG reports for acetone, alkylamines, ammonia, barium, cadmium, caprolactam, formate, formaldehyde, manganese, total organic carbon, and zinc are included in this report. The committee concludes that the SWEGs developed for these chemicals are scientifically valid based on the data reviewed by NASA and are consistent with the NRC (2000) report, Methods for Developing Spacecraft Water Exposure Guidelines. SWEG reports for additional chemicals will be presented in a subsequent volume.

Pharmacokinetics, the study of the movement of chemicals within the body, is a vital tool in assessing the risk of exposure to environmental chemicals. This bookâ€"a collection of papers authored by experts in academia, industry, and governmentâ€"reviews the progress of the risk-assessment process and discusses the role of pharmacokinetic principles in evaluating risk. In addition, the authors discuss software packages used to analyze data and to build models simulating biological phenomena. A summary chapter provides a view of trends in pharmacokinetic modeling and notes some prospective fields of study.
