Book excerpt: The commercial polybrominated diphenyl ether (PBDE) mixture known as PentaBDE was once the primary flame retardant (FR) used in the US to comply with California's Technical Bulletin 117 (TB117) - a mandated flammability standard for polyurethane foam within upholstered furniture and baby products. In 2004, due to concerns about persistence, bioaccumulation, and toxicity, PentaBDE was voluntarily phased out, prompting an industry-wide shift toward the use of alternative flame retardant formulations containing at least one of the two major classes of organophosphate-based flame retardants (OPFRs) - chlorinated phosphate esters (CPEs) and aryl phosphate esters (APEs). Due to rapid adoption as PentaBDE replacements, organophosphate-based flame retardants (OPFRs) have been detected at concentrations comparable to and, in some cases, higher than total PBDE concentrations in household dust, suggesting that chronic human exposure to these alternative flame retardants following leaching from treated products is common within the United States. Despite the need for a better understanding of the potential developmental effects of OPFRs (since infants and children tend to (1) ingest more house dust than adults due to crawling and mouthing behaviors and (2) be exposed up to five times the acceptable daily OPFR intake level due to use in residential furniture), most studies to date have focused on the genotoxicity or neurotoxicity of OPFRs within adult animals. Using zebrafish as an animal model, the objective of these studies was to begin uncovering the mechanisms of developmental toxicity for OPFRs commonly detected within indoor environments. Our results demonstrate that the two major classes of OPFRs - CPEs and APEs - exhibit distinct mechanisms of toxicity during zebrafish embryogenesis. Specifically, exposure to the high-production volume CPE tris(1,3- dichloro-2-propyl) phosphate (TDCPP) delayed zygotic genome remethylation during early embryogenesis, while exposure to triphenyl phosphate (TPP) and monoisopropylated triaryl phosphate (Mono-ITP) - two APEs that account for 49% of Firemaster 550, a major PentaBDE replacement - resulted in severe cardiac abnormalities during early vertebrate development. Overall, these results are the first to show early developmental toxicity of widely used and detected OPFRs.

This book was released on 2019-07-19 with total page 103 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the 1970s, flame retardants began to be added to synthetic materials to meet strict flammability standards. Over the years, diverse flame retardants have been manufactured and used in various products. Some flame retardants have migrated out of the products, and this has led to widespread human exposure and environmental contamination. There also is mounting evidence that many flame retardants are associated with adverse human health effects. As a result, some flame retardants have been banned, restricted, or voluntarily phased out of production and use. This publication develops a scientifically based scoping plan to assess additive, nonpolymeric organohalogen flame retardants as a class for potential chronic health hazards under the Federal Hazardous Substances Act, including cancer, birth defects, and gene mutations.

This book was released on 2019 with total page 119 pages. Available in PDF, EPUB and Kindle. Book excerpt: Organohalogen flame retardants are extensively used in both industrial and consumer products but now are being phased out of circulation by both state governments and the United States Federal government. Organophosphate flame retardants have been chosen as the replacement for the halogenated flame retardants. However, relatively little is known about the potential hazard of these class of chemicals to cause adverse health and environmental effects. To address this, we conducted a health and environmental hazard screening of 90 halogenated and 97 organophosphate flame retardants based on the GreenScreen® or Quick Chemical Assessment Tool (QCAT©) methodologies. Priority consideration was given to human health hazards including carcinogenicity (including mutagenicity and genetic toxicity), reproductive or developmental toxicity, endocrine disruption, and acute mammalian toxicity. Environmental hazards given priority consideration included acute aquatic toxicity, persistence, and bioaccumulation. Using publicly available information, each hazard category was assigned a concern level (very-low, low, moderate, high, or very high) based on pre-defined numerical ranges, such as no-observed adverse effect levels and hazard classification schemes from authoritative sources, when available. Where empirical data were not identified, quantitative structure-activity relationship (QSAR) models were relied upon to predict hazard potential. After assigning concern levels for each priority health effect, each chemical received a score, similar to a report card (A, B, C, or F). The majority of the screened chemicals received an F grade due to empirical data suggesting high hazard, QSAR model predictions, and/or excessive data gaps. Acute Mammalian Toxicity was the most prominent potential health hazard identified based on empirical data. The most prevalent data gap was found in both reproductive toxicity and endocrine disruption endpoints due to the lack of identified empirical data or computer models able to predict this hazard. This study highlights the limited toxicity information available for these widely used chemical classes and indicates that more testing and oversight is critically needed to identify safer alternatives for fire prevention.

Available in PDF, EPUB and Kindle. Book excerpt: This text/reference book provides the most comprehensive coverage of anticholinesterase compounds (Organophosphates and Carbamates), which constitute the largest number of chemicals that are primarily used as insecticides in agriculture, industry, and around the home/garden. Some OPs (nerve agents) have been used in chemical warfare and terrorist attacks, while some OPs and CMs have been recommended as therapeutic agents in human medicine as well as in veterinary medicine. Many chemicals of both classes are extremely toxic and lack selectivity, thus their inadvertent/accidental use continues to pose a threat to human and animal health, aquatic systems and wildlife. These anticholinesterase agents produce a variety of toxicological effects in target and nontarget organs. In light of this complexicity, this multi-authored book is written by the well known scientists from many countries. The book is organized into nine sections, with a total of 49 chapters, to provide in-depth knowledge on various aspects of OP and CM compounds, including their use, classification, mechanism-based toxicity, and prophylactic and therapeutic measurements. Several chapters are written with special emphasis to cover timely topics, such as chemical warfare agents, physiologically-based pharmacokinetic modeling, structure and function of cholinesterases, paraoxonase, carboxylesterases; developmental neurotoxicity, the intermediate syndrome, oxidative stress, endocrine disruption, and DNA damage/gene expression and carcinogenesis. Section-VI with 5 chapters is specifically devoted to risk assessment, and safety and regulatory guidelines for pesticides. Describes everything you need to know about Organophosphates and Carbamates Extensively covers pesticides, nerve agents, therapeutic drugs, and flame retardants Describes epidemiology of the world's major disasters involving Organophosphates and Carbamates Covers animal, human, aquatic, and wildlife toxicity of Anticholinesterases Insights into in-depth cholinergic and noncholinergic mechanisms of toxicity Describes recent advancements in cholinesterases, paraoxonases, carboxylesterases, oxidative stress, endocrine disruption, cardiac and pulmonary toxicity, and carcinogenesis Provides in vitro and in vivo models for neurotoxicity testing Integrates knowledge of studies in lab animals and humans Offers risk/safety assessment and national/international guidelines for permissible levels of pesticide residues Describes management of Anticholinesterase poisoning in humans

Available in PDF, EPUB and Kindle. Book excerpt: A one-stop, practical handbook containing all of the current commercial non-halogenated flame retardant technologies as well as experimental systems near commercialization In response to the emphasis on replacing halogenated flame retardants with alternate technologies, this handbook focuses on existing non-halogenated flame retardants and the experimental close-to-production systems that are available today. The Non-Halogenated Flame Retardant Handbook starts with an overview of the regulations and customer perceptions driving non-halogenated flame retardant selections over older halogenated technologies. It then moves on to cover the known major classes of non-halogenated flame retardants, before concluding with the current niche-performing technologies and untried commercial contenders of the future. The Non-Halogenated Flame Retardant Handbook: Takes a practical approach to addressing the narrow subject of non-halogenated flame retardancy—placing more emphasis on flame retardant selection for specific plastics, practical considerations in flame retardant material design, and the various technologies’ strengths and limits Focuses on the proper use of non-halogenated flame retardants, rather than the mechanics of how they work Discusses important future trends in flame retardancy Features sections written by industrial and chemical experts who know how to apply the technology to polymers for fire safety needs

This book was released on 2000-07-06 with total page 534 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ignition of upholstered furniture by small open flames from matches, cigarette lighters, and candles is one of the leading causes of residential-fire deaths in the United States. These fires accounted for about 16% of civilian fire deaths in 1996. On average, each year since 1990, about 90 deaths (primarily of children), 440 injuries, and property losses amounting to 50 million dollars have resulted from fires caused by the ignition of upholstered furniture by small open flames. Certain commercial seating products (such as aircraft and bus seats) are subject to flammability standards and sometimes incorporate FR-treated upholstery cover materials, but there is no federal-government requirement for residential upholstered furniture, and it is generally not treated with FR chemicals. It is estimated that less than 0.2% of all U.S. residential upholstery fabric is treated with flame-retardant (FR) chemicals. The Consumer Product Safety Act of 1972 created the U.S. Consumer Product Safety Commission (CPSC) as an independent federal regulatory agency whose mission is to protect the public from unreasonable risks of injury and death associated with consumer products. CPSC also administers the Flammable Fabrics Act, under which it regulates flammability hazards and the Federal Hazardous Substances Act (FHSA), which regulates hazardous substances including chemicals. In 1993, the National Association of State Fire Marshals petitioned CPSC to issue a performance-based flammability standard for upholstered furniture to reduce the risk of residential fires. The Commission granted that portion of the petition relating to small open flame ignition risks. In response to concerns regarding the safety of FR chemicals, Congress, in the fiscal year 1999 appropriations report for CPSC, requested that the National Research Council conduct an independent study of the health risks to consumers posed by exposure to FR chemicals that are likely to be used in residential upholstered furniture to meet a CPSC standard. The National Research Council assigned the project to the Committee on Toxicology (COT) of the Commission on Life Sciences' Board on Environmental Studies and Toxicology. COT convened the Subcommittee on Flame-Retardant Chemicals, which prepared this report. Subcommittee members were chosen for their recognized expertise in toxicology, pharmacology, epidemiology, chemistry, exposure assessment, risk assessment, and biostatistics. Toxicological Risks of Selected Flame-Retardant Chemicals is organized into 18 chapters and two appendices. Chapter 2 describes the risk assessment process used by the subcommittee in determining the risk associated with potential exposure to the various FR chemicals. Chapter 3 describes the method the subcommittee used to measure and estimate the intensity, frequency, extent, and duration of human exposure to FR chemicals. Chapters 4-19 provide the subcommittee's review and assessment of health risks posed by exposure to each of the 16 FR chemicals. Data gaps and research needs are provided at the end of these chapters.

Available in PDF, EPUB and Kindle. Book excerpt: Green toxicology is an integral part of green chemistry. One of the key goals of green chemistry is to design less toxic chemicals. Therefore, an understanding of toxicology and hazard assessment is important for any chemist working in green chemistry, but toxicology is rarely part of most chemists' education. As a consequence, chemists lack the toxicological lens necessary to view chemicals in order to design safer substitutions. This book seeks to fill that gap and demonstrate how a basic understanding of toxicology, as well as the tools of in silico and in vitro toxicology, can be an integral part of green chemistry. R&D chemists, product stewards, and toxicologists who work in the field of sustainability, can all benefit from integrating green toxicology principles into their work. Topics include in silico tools for hazard assessment, toxicity testing, and lifecycle considerations, this book aims to act as a bridge between green toxicologists and green chemists.

Available in PDF, EPUB and Kindle. Book excerpt: Flammability has been recognized as an increasingly important social and scientific problem. Fire statistics in the United States (Report of the National Commission on Fire Prevention and Control. "America Burning:' 1973) emphasized the vast devastation to life and property--12.000 lives lost annually due to fire. and these deaths are usually caused by inhaling smoke or toxic gases: 300.000 fire injuries: 11.4 billion dollars in fire cost at which 2.7 billion dollars is related to property loss: a billion dollars to burn injury treatment: and 3.3 billion dollars in productivity loss. It is obvious that much human and economic misery can be attributed to fire situations. In relation to this. polymer flammability has been recognized as an in creasingly important social and scientific problem. The development of flame-retardant polymeric materials is a current example where the initia tive for major scientific and technological developments is motivated by sociological pressure and legislation. This is part of the important trend toward a safer environment and sets a pattern for future example. Flame retardancy deals with our basic everyday life situations-housing. work areas. transportation. clothing and so forth-the "macroenvironment" capsule within which "homosapiens" live. As a result. flame-retardant polymers are now emerging as a specific class of materials leading to new and diversified scientific and technological ventures.

Available in PDF, EPUB and Kindle. Book excerpt: This book serves as a comprehensive resource on toxicants that can be released from food packaging materials and household plastics. Chapters include sources and levels of chemical exposure, known and suspected health effects and the identification of data gaps with recommendations for further research. In addition, regulatory approaches and risk assessment challenges in the United States and Europe are discussed. Chapters cover both the more widely known chemicals that can migrate from food packaging (bisphenol A, perfluorinated chemicals), and household plastics (lead, phthalates, brominated flame retardants), as well as chemicals that are just entering use in food packaging (nanomaterials in polymer food packaging) and chemicals recently identified as migrating from food packaging to food stuffs (phthalates, benzophenones, antimony, methylnaphthalene and the alkylphenols nonylphenol and octylphenol). Chapters on phthalates and brominated flame retardants discuss challenges that arise with the use of replacement chemicals. The health effect sections of chapters have drawn on a wide variety of toxicological endpoints and recommend approaches to better assess toxicological risks in vulnerable human populations. Reflecting the global nature of our food supply and household consumer goods, contributions have been drawn from international experts. A wide range of scientists will find this book to be useful, including toxicologists, environmental health scientists, food scientists, and regulators.
