Polycyclic aromatic hydrocarbons (PAHs) are a major category of ubiquitous environmental contaminants. PAHs are of major concern because of ubiquity, mutagenicity/carcinogenicity, bioaccumulative nature and ability to transport to longer distances as well as in the food chain. These pollutants are contaminating all segments of the environment in large quantities by various anthropogenic activities resulting in ecological imbalance. The rapid advancement of technology, industrial development and application of toxic substances has resulted in the contamination of different components of the environment. This contributed volume serves as a comprehensive compilation of different sources and remediation methods for PAH contamination in the environment.

Résumé
Polycyclic aromatic hydrocarbons (PAHs) are an emerging contaminant of global concern due to their carcinogenic/mutagenic nature, ubiquitous occurrence, long range transport, bioaccumulative characteristics, involvement in food chain and food web as well as toxicity in almost all segments of the environment. This contributed volume offers chapters that provide a detailed description of PAH ubiquity, sources, distribution, fate, derivatives, transport, detection techniques as well as remediation methods. Various anthropogenic activities are responsible for their dangerous concentrations of PAHs in the environment. The detection and remediation of such contaminants is the major challenge that this book aims to address. The chapters here provide cases detailing different adsorptive as well as photochemical and biological mechanisms for PAH removal . Green technologies, multidisciplinary approaches and new advancements for PAH remediation are also emphasized for better applicability with the aim of environmental sustainability.
