Chemical Exposures

Traditionally, industrial hygienists and environmental engineers have been responsible for conducting chemical exposure assessments, however, this task is now becoming a team effort taken on by scientists, businessmen, and policymakers. Assessment of Chemical Exposures: Calculation Methods for Environmental Professionals addresses the expanding scope of exposure assessments in both the workplace and environment. It discusses the basics of gathering data and assessing exposure, including how to estimate exposure to chemicals using fundamental chemical engineering concepts. The book opens with a brief discussion on the history of exposure assessments and provides terms and nomenclature needed for communications between various disciplines involved in exposure assessments. The potential impact of chemical exposures on humans, the environment, and communities is discussed in detail The book also addresses modeling source generation, pathway transport, and receptor impact. With the clear explanations presented in this text, even a novice will be able to practice the art of exposure assessment.

Providing material for practitioners and students alike, Chemical Exposure and Toxic Responses is a clear and straightforward presentation of industrial toxicology. Exposure to toxic chemicals is of major concern to health professionals. In recent years, the scope and importance of hazardous materials toxicology has expanded and now impacts financial institutions, government, private corporations, and many other organizations as well. Chemical Exposure and Toxic Responses presents the myriad health implications of hazardous chemicals in a single source. This book is organized so that readers can proceed from a general perspective on the problem of chemical exposure and toxic responses to an understanding of toxicology and a method of inquiry. Written for anyone who needs practical toxicological information, the book compactly and efficiently presents the scientific basis of toxicology as it applies to the workplace. It covers the diverse chemical hazards encountered in the work environment and provides a practical understanding of these hazards for those charged with protecting the health and well being of people at work. Chemical Exposure and Toxic Responses consists of three parts: Part I establishes the general principles of industrial toxicology; Part II addresses specific effects of toxic agents on specific physiological organs and systems; and Part III is devoted to the evaluation of hazards in the workplace.

People are exposed to a variety of chemicals throughout their daily lives. To protect public health, regulators use risk assessments to examine the effects of chemical exposures. This book provides guidance for assessing the risk of phthalates, chemicals found in many consumer products that have been shown to affect the development of the male reproductive system of laboratory animals. Because people are exposed to multiple phthalates and other chemicals that affect male reproductive development, a cumulative risk assessment should be conducted that evaluates the combined effects of exposure to all these chemicals. The book suggests an approach for cumulative risk assessment that can serve as a model for evaluating the health risks of other types of chemicals.

In fact, with the control and containment of most infectious conditions and diseases of the past millennium having been achieved in most developed countries, and with the resultant increase in life expectancies, much more attention seems to have shifted to degenerative health problems. Many of the degenerative health conditions have been linked to thousands of chemicals regularly encountered in human living and occupational/work environments. It is important, therefore, that human health risk assessments are undertaken on a consistent basis - in order to determine the potential impacts of the target chemicals on public health.

The bestselling resource on industrial chemical assessment just got better. A practical guide to biological monitoring for industrial chemical exposure assessment, the THIRD EDITION of INDUSTRIAL CHEMICAL EXPOSURE: GUIDELINES FOR BIOLOGICAL MONITORING has been completely revised to include the latest developments in the field. In addition to an update of each chapter, major revisions have been made to take into consideration new information available since the publication of the second edition. SEE WHAT'S NEW IN THE THIRD EDITION: Major changes to the sections on lead, benzene, trichloroethylene, and dimethylformamide Fourteen completely new topics: bromine, molybdenum, perchlorate, platinum, n-heptane, ethene, 1,3-butadiene trimethylbenzene, naphthalene, terpenes, acrylamide, pesticides, tetrahydrofuran, methyl tertiarybutyl ether, n-nitrosodiethylamine Discussion of the metabolic fate of chemicals Increased information on the threshold of adverse effects levels Development of biological monitoring methods for assessing the internal dose of additional chemicals This authoritative book summarizes what is known about biological monitoring for inorganic, organic and organometallic substances. It provides a summary table with practical recommendations, giving you quick and easy access to the data. With INDUSTRIAL CHEMICAL EXPOSURE: GUIDELINES FOR BIOLOGICAL MONITORING you will understand the objectives of biological monitoring, the types of biological monitoring methods, their advantages and limitations, as well as practical aspects that must be considered before initiating a biological monitoring program.

The NIOSH Pocket Guide to Chemical Hazards presents information taken from the NIOSH/OSHA Occupational Health Guidelines for Chemical Hazards, from National Institute for Occupational Safety and Health (NIOSH) criteria documents and Current Intelligence Bulletins, and from recognized references in the fields of industrial hygiene, occupational medicine, toxicology, and analytical chemistry. The information is presented in tabular form to provide a quick, convenient source of information on general industrial hygiene practices. The information in the Pocket Guide includes chemical structures or formulas, identification codes, synonyms, exposure limits, chemical and physical properties, incompatibilities and reactivities, measurement methods, respirator selections, signs and symptoms of exposure, and procedures for emergency treatment.

The book contains the contributions at the NATO Study Institute on Exposure and Risk Assessment of Chemical Pollution – Contemporary Methodology, which took place in Sofia – Borovetz, Bulgaria, July 1–10, 2008. Rapid advances in mathematics, computer science and molecular biology and chemistry have lead to the development in of a new branch of toxicology called Computational Toxicology. This emerging field is addressing the estimation and prediction of exposure risk and effects of chemicals based on experimental data, measured concentration and biological mechanisms and computational models of biological systems. Mathematical models are also being used to predict the fate and transport of substances in the environment. Because this area is still in its infancy, there has been limited application from governmental agencies to regulating controllable processes, such as registration of new chemicals, determination of estimated exposure and risk based limits and maximum acceptable concentrations in different compartments of the environment – ambient air, waters, soil and food products. However, this is soon to change as the ability to collect, analyze and interpret the required information is becoming increasingly more efficient and cost effective. Full implementation of the new processes have to involve education on both part of the experimentalists who are generating the data and the models, and the risk assessors who will use them to better protect human health and the environment.
