Per- and polyfluorinated alkyl substances (PFAS), often referred to as per- (and poly) fluorinated compounds (PFCs), have been used for years in many everyday¾ and some lifesaving¾ 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.
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.

This series presents the fundamentals of emerging issues in environmental and occupational health. It specifically focuses on their impact to human health. With advances in analytical technology, our understanding of environmental health issues has dramatically increased over the past several years. Topics such as drinking water treatment in austere environments, air pollution in urban and developing areas, indoor air quality, and emerging contaminants in wastewater treatment are relevant to today’s researchers and policy makers. Likewise, protection for workers’ health is ever-increasing, and this series addresses the state-of-the-art in topics such as respiratory protection, radiation protection, engineering controls, and management techniques.
