This title includes a number of Open Access chapters. The focus of this book is on unique exposures that occur indoors, typically, but not exclusively in residences, where recent advances have been made on identification of the pollutants in indoor environments, the health effects associated with indoor or personal exposures, or interventions that can be implemented by typical occupants to mitigate exposures. The book covers a wide selection of indoor exposures to chemical and biological pollutants, including lead, phthalates, flame retardants, mold, infectious diseases, traffic-related particulate, pesticides, PCBs, VOCs, and asthma triggers (ETS, mold, cat allergen). This book is unique in that very recent research is discussed in this rapidly expanding field.
