Confusion now hath made his masterpiece Macbeth II iii 72 Whence and what are those execrable shape? Paradise Lost Ib 1 681 Confusion worse confounded Paradise Lost Ib 1 995 When the manuscript for the first part of this book was proposed, it was anticipated that the discussion of the entire field of protein se quencing could be covered in a single volume - from purification and characterization of the protein through fragmentation by chemical or enzymic means and, finally, to reassembly of the identified individual peptides into the reconstructed total sequence. It soon became evident that this would not be possible. While the intent was to restrict the expose of procedures only to that information concerned with "hands on" wet chemistry, it became apparent that a thorough presentation would require, in addition, a discussion of certain instrumental and more theoretical approaches not included in the first volume. Furthermore, the entire understanding of the field of protein sequencing has advanced appreciably since the inception of this book. The purpose of the first volume was to provide practical information in sufficient detail to permit the researcher to undertake the actual sequencing procedures in his own laboratory."

Chromium in the Natural and Human Environments Edited by Jerome O. Nriagu and Evert Nieboer "Essential reading for researchers and students of environmental and occupational health effects of metals." - The Science of the Total Environment Representing the most comprehensive coverage to date on the uses of chromium, its sources (both natural and anthropogenic), and occurrence in the air, water, and soil, this timely volume addresses the growing concern about chromium's ultimate effect on the environment. The toxicity of chromium to terrestrial and aquatic biota is examined in relation to its chemistry and biochemistry, with discussion of toxicological models of chromium hypersensitivity, mutagenicity, carcinogenicity, and toxicokinetics. Features include graphical representation of the voluminous mutagenicity and animal carcinogenicity data according to chromium compound type. 1988 (0 471-85643-6) 571 pp. Cadmium in the Aquatic Environment Edited by Jerome O. Nriagu and John B. Sprague "This book contains a wealth of information useful to many different types of scientists." - Journal of the American Chemical Society Considered a priority natural water contaminant, cadmium has, like other toxic metals, been closely monitored. Featuring the latest research of some of the world's leading environmental specialists, this important text is a comprehensive look at the sources, distribution, and fate of cadmium in aquatic ecosystems, as well as the biocycling and ecotoxicity of cadmium in natural waters. The book's topical breadth also includes cadmium associations in freshwater and marine sediments, the latest techniques used for cadmium detection, and the scientific rationale needed to establish water quality criteria and standards for the presence of cadmium. 1987 (0 471-85884-6)272pp. Food Contamination From Environmental Sources Edited by Jerome O. Nriagu and Milagros S. Simmons "The quality of the writing is uniformly high the book will serve as a valuable reference to graduate-level readers in food science, public health, and toxicology, as well as to environmental biologists and chemists " - Choice The exposure of all levels of the human food chain to environmental contaminants has transformed the human body into a biomonitor of environmental pollutants. This international collection of 22 studies from leading researchers examines every facet of the problem. The book's far-ranging and detailed coverage includes the detection, sources, distribution, speciation, and bioavailability of environmental contaminants and their metabolites in various food products, as well as the toxicological and health significance of the observed contaminant levels in foods. 1990 (0 471-50891-8) 785 pp.
