Biomarkers have emerged as an exciting tool in disease prevention, particularly in the workplace. They may be used to document workers' exposure to toxins, signal the onset of health effects, or identify individuals with susceptibility to certain environmental threats. But the uncertainty is as great as the potential. Are biomarkers suitable for widespread use? How can they be deployed in diverse contexts? How can biological information about workers be handled fairly and ethically? Biomarkers and Occupational Health describes the state of biomarker development, including the implications of the Human Genome program, and presents a range of viewpoints on the future of biomarkers from the leaders in the field. This book explores the three basic types of biomarkers (markers of exposure, markers of health effects, and markers of susceptibility to disease) from a variety of perspectives. It examines what can be learned from well-known exposure sitesâ€"Hiroshima and Nagasaki, Chernobyl, and the Hanford nuclear site in the United States, for exampleâ€"and a wide range of human cases and animal studies. The book also explores the costs and ramifications of developing a large-scale program to monitor potentially exposed workers (e.g., at a cleanup site). A framework is offered for the use of biomarkers based on the mandate to "change the environment before you change the worker." The book explores how to identify ethical issues, how to set development priorities, and how to integrate biomarkers into an occupational health and safety program. The authors present the latest technical findings about markers for chronic beryllium disease as well as markers for exposure to carcinogens, radiation, and chroniumâ€"including prospects for detecting long-past exposures. Biomarkers and Occupational Health offers an update on biomarker development and explores a wide scope of issues. This book will be important to occupational health professionals, biomedical researchers, toxicologists, epidemiologists, and labor and management officials involved in worker health issues.

Biological markers (biomarkers) are useful tools for understanding the nature and extent of human exposure and risk from environmental toxicants. Biomarkers are classified into three basic categories: exposure, effect, or susceptibility. A marker of exposure is the product of the interaction between a target cell or molecule and a foreign substance (NAS, 1989). These markers can be used to determine the biologically effective dose necessary to elicit a particular physiological change in an organism. A marker of effect is a biochemical or physiological change in an organism that can predict the onset of adverse health effects resulting from a given exposure. Lastly, markers of susceptibility act as indicators of an inherent or acquired tendency of an organism to experience an adverse health effect (NAS, 1989). These markers are already used to detect a variety of diseases and show great promise for developing a better understanding of the mechanicisms of disease. Additionally, biomarkers can be used to establish a more rational basis for quantitative risk extrapolation between species, as weIl as to obtain more precise estimates of the time of critical exposure. These markers can also prove helpful in identifying potentially damaging exposures before the onset of adverse health effects. Biomarkers serve as a valuable exposure assessment tool because they take into account exposure from all routes and integrate exposure from all sources. They have the potential to yield better risk estimates than current monitoring and modeling protocols. In lune 1992, Dr. Travis and Dr.

A research and development priority in the area of occupational environmental health surveillance (OEHS) is the development of biomarkers of exposure, effect, and susceptibility. As exposure monitoring using environmental sampling equipment can be impractical and doesn't account for differences in individual responses, new methodologies must be sought. Biomarkers offer the opportunity to quantify toxic exposures and effects in individuals before, during, and after deployments. Therefore, concerted efforts in this area of research are underway at the U.S. Army Center for Environmental Health Research (USACEHR). This report demonstrates the feasibility of using in vitro cellular models as biomarker discovery tools. The combination of these models with state of the art proteomic screening technologies and an enzyme-linked immunosorbent assay (ELISA), provides insight into the effects of trinitrotoluene (TNT), dinitrobenzene (DNB), and the carbamate aldicarb. The results of these toxicant exposures are discussed.

Biomonitoring—a method for measuring amounts of toxic chemicals in human tissues—is a valuable tool for studying potentially harmful environmental chemicals. Biomonitoring data have been used to confirm exposures to chemicals and validate public health policies. For example, population biomonitoring data showing high blood lead concentrations resulted in the U.S. Environmental Protection Agency's (EPA's) regulatory reduction of lead in gasoline; biomonitoring data confirmed a resultant drop in blood lead concentrations. Despite recent advances, the science needed to understand the implications of the biomonitoring data for human health is still in its nascent stages. Use of the data also raises communication and ethical challenges. In response to a congressional request, EPA asked the National Research Council to address those challenges in an independent study. Human Biomonitoring for Environmental Chemicals provides a framework for improving the use of biomonitoring data including developing and using biomarkers (measures of exposure), research to improve the interpretation of data, ways to communicate findings to the public, and a review of ethical issues.

Volume 17, entitled Lead: Its Effects on Environment and Health of the series Metal Ions in Life Sciences centers on the interrelations between biosystems and lead. The book provides an up-to-date review of the bioinorganic chemistry of this metal and its ions; it covers the biogeochemistry of lead, its use (not only as gasoline additive) and anthropogenic release into the environment, its cycling and speciation in the atmosphere, in waters, soils, and sediments, and also in mammalian organs. The analytical tools to determine and to quantify this toxic element in blood, saliva, urine, hair, etc. are described. The properties of lead(II) complexes formed with amino acids, peptides, proteins (including metallothioneins), nucleobases, nucleotides, nucleic acids, and other ligands of biological relevance are summarized for the solid state and for aqueous solutions as well. All this is important for obtaining a coherent picture on the properties of lead, its effects on plants and toxic actions on mammalian organs. This and more is treated in an authoritative and timely manner in the 16 stimulating chapters of Volume 17, which are written by 36 internationally recognized experts from 13 nations. The impact of this recently again vibrant research area is manifested in nearly 2000 references, over 50 tables and more than 100 illustrations (half in color). Lead: Its Effects on Environment and Health is an essential resource for scientists working in the wide range from material sciences, inorganic biochemistry all the way through to medicine including the clinic ... not forgetting that it also provides excellent information for teaching.

Human biomonitoring has developed from a research tool in occupational and environmental health to identify and quantify exposures to harmful substances in urine and blood. The analytical methods for detection of substances in biological media have considerably improved with smaller detection limits and more precise and specific measurements. Human biomonitoring is a valuable tool in exposure estimation of selected populations and currently used in surveillance programs all over the world. This two volume set provides an overview of current available biomarkers and human biomonitoring programs in environmental health, which is timely given the present debate on adverse health effects from environmental exposures. The books decribe both previous and ongoing studies as well as the newer biomarkers of exposure and effects. Volume one describes current human biomonitoring programs in Germany, Romania, France, Canada, India and Belgium, providing convincing evidence of a global decline in human exposures to lead and increasing concern from exposure to endocrine disruptors and the genotoxic compound. Biomarkers of specific exposures to a wide range of widely used everyday compounds such as phthalates, PFCs, bisphenol A, brominated flame retardants, PAHs, dioxins, mercury and arsenic are also discussed. Volume two decribes human biomonitoing of exposures to environmental tobacco smoke, mycotoxins, physiological stress, hormone activity, oxidative stress and ionizing radiation, as well as effect biomarkers of hemoglobin adducts, germ cells, micronuclei and individual susceptability. The books will be essential reading for toxicologists, environmental scientists and all those working in the safety and risk assessment of chemicals.
