Per- and polyfluorinated alkyl substances (PFAS), often referred to as per- (and poly) fluorinated compounds (PFCs), have been used for years in many everyday3⁄4 and some lifesaving3⁄4 products. However, their use has been linked to adverse health effects in humans, a problem compounded by their persistence in the environment. This book discusses the various challenges of PFAS in our environment today, including their historical use as well as their chemical and toxicological properties. It also presents robust discussion of analytical challenges and special considerations in sampling. The work goes on to give practical recommendations for dealing with these compounds in today's dynamic regulatory landscape and includes several chapters on various remediation techniques. Key Features: Comprehensive overview of per- and polyfluorinated alkyl substances (PFAS) historical use and chemical/physical properties which help us understand their persistence, transport, and transformation pathways in the environment In-depth analysis of PFAS toxicology Detailed descriptions of conventional and state-of-the-art remediation technologies Practical recommendations for dealing with PFAS in a dynamic regulatory landscape Robust discussion of important sampling and analytical considerations Perfluoroalkyl Substances in the Environment: Theory, Practice, and Innovation explores the challenges across the topical areas of regulation and management, toxicology, environmental remediation, and analytical sampling and analysis.Readers will find this text helpful in understanding complexities associated with PFAS and informing management strategies to effectively protect this and future generations.

A concise assessment of the risks to human health posed by exposure to 1 1 1 2-tetrafluoro-ethane, a gaseous fluorocarbon used primarily as a refrigerant for high-temperature refrigerators, including domestic refrigerators and automobile air conditioners. Concerning environmental behavior, the report cites evidence that 1 1 1 2-tetrafluoroethane partitions almost exclusively to the atmosphere. Limited evidence suggests that the chemical does not accumulate in biota or adsorb to soil or sediment. The chemical's overall lifetime in the troposphere is estimated to be 14.6 years. Recent observations show a rapid increase in atmospheric concentrations, mainly as a result of emissions over the past decade. Modeling indicates insignificant ozone depletion potential, significant global warming potential, and negligible acidification potential. Data on toxic effects are limited. Animal studies have identified a reduction in maternal body weight gain in rabbits and signs of delayed fetal development in rats. Studies of carcinogenicity were judged to be inconclusive. Data on health effects in humans are limited to a single study conducted in volunteers. The study found no abnormalities following exposure via inhalation and no clinical signs of toxicity. The low toxicity of 1 1 1 2-tetrafluoroethane to the few aquatic organisms tested, as well as the chemical's high volatility, indicate that risks to aquatic organisms are negligible.
