Human Biomonitoring For Environmental Chemicals

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.

In this context, the science-policy interface of the EU project HBM4EU -is particularly important, ensuring up-to-date and coordinated science-based information for policy makers. HBM in research in all Nordic countries has substantially benefited from HBM4EU participation – time trends, aligned studies, mechanistic studies, and method development/improvement are examples of HBM4EU activities in Nordic countries. And also vice versa, as- high quality, structured, reliable, well planned and effectively conducted HBM studies in Nordic countries have contributed significantly to HBM4EU.The chromate study conducted in HBM4EU can be considered exemplary, in terms of providing a science-based answer to a policy question.

Biomonitoring is the assessment of human exposure to chemicals by measuring the chemicals of their metabolites in such human specimens as blood and urine. Most chemicals or their metabolites were measured in blood, serum and urine samples from random subsamples of about 2500 participants from the National Health and Nutrition Examination Survey conducted by the Centers for Disease Control (CDC). This book explores the ongoing assessment of the exposure of the U.S. population to environmental chemicals by the use of biomonitoring. It provides unique exposure information to scientists, physicians, and health officials to help prevent exposure to some environmental chemicals. (Imprint: Nova)

Book & DVD. This book provides an ongoing assessment of the exposure of the U.S. population to environmental chemicals by the use of biomonitoring.

From the use of personal products to our consumption of food, water, and air, people are exposed to a wide array of agents each day-many with the potential to affect health. Exposure Science in the 21st Century: A Vision and A Strategy investigates the contact of humans or other organisms with those agents (that is, chemical, physical, and biologic stressors) and their fate in living systems. The concept of exposure science has been instrumental in helping us understand how stressors affect human and ecosystem health, and in efforts to prevent or reduce contact with harmful stressors. In this way exposure science has played an integral role in many areas of environmental health, and can help meet growing needs in environmental regulation, urban and ecosystem planning, and disaster management. Exposure Science in the 21st Century: A Vision and A Strategy explains that there are increasing demands for exposure science information, for example to meet needs for data on the thousands of chemicals introduced into the market each year, and to better understand the health effects of prolonged low-level exposure to stressors. Recent advances in tools and technologies-including sensor systems, analytic methods, molecular technologies, computational tools, and bioinformatics-have provided the potential for more accurate and comprehensive exposure science data than ever before. This report also provides a roadmap to take advantage of the technologic innovations and strategic collaborations to move exposure science into the future.

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.

This overview is a companion piece to the Third Report on Human Biomonitoring of Environmental Chemicals in Canada. It provides context for the Report as well as some background information on biomonitoring.
