Since the first edition in 1948, Patty's Industrial Hygiene and Toxicology has become a flagship publication for Wiley. In the course of its nearly six decades in print, it has evolved into a standard reference for the fields of occupational health and toxicology. The volumes on Industrial Hygiene are cornerstone reference works for chemists, engineers, toxicologists, and occupational safety personnel. Volume 1 covers Introduction of Industrial Hygiene and Recognition of Chemical Agents. In addition to revised and updated chapters, a number of new chapters reflect current technology and concerns. The chapters include Nano-Materials, Chemical Toxicants including endocrine disruptors, Exposures in a Multicontaminant Environment, and Real Time Assessment for Contaminants.
