    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.

    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.
