Human Biomonitoring At Food Authorities

Human biomonitoring (HBM) can be defined as the systematic standardized measurement of a concentration of a substance or its metabolites in human tissues and is an important tool in evaluating exposure to chemicals. This report maps HBM studies performed at or initiated by food safety authorities in the Nordic countries and discuss problems and options for further work. The report shows that only few studies have been performed and it differs among the countries. Reasons for this could be that sampling blood and urine is demanding, there are ethical and privacy issues and analytical costs are high. More cooperation with researchers and between countries is needed. Food safety authorities have special responsibilities in cases of emergencies and disasters. In these cases HBM provides a good tool for exposure measurement but cooperation and infrastructure should be established beforehand.

This report is based on the seminar “Human biomonitoring (HBM) as a tool in policy making towards consumer safety” directed towards professionals involved in HBM programs, legislators and other policy-makers, risk assessors as well as researchers from universities and other higher educational institutions. It was organized by the Swedish National Food Agency in collaboration with the Norwegian Food Safety Authority, the Norwegian Institute of Public Health, the University of Iceland, and Karolinska Institute, Sweden. Experts from Europe, USA, and Canada within the field of HBM participated. It was agreed that HBM provides a powerful tool in policy making towards consumer safety. It was also concluded that there is interest to develop the Nordic collaborative efforts within the area of HBM and that there would, unquestionably, be benefits from this in terms of harmonization.

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.

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.

Mineral elements are found in foods and drink of all different types, from drinking water through to mothers’ milk. The search for mineral elements has shown that many trace and ultratrace-level elements presented in food are required for a healthy life. By identifying and analysing these elements, it is possible to evaluate them for their specific health-giving properties, and conversely, to isolate their less desirable properties with a view to reducing or removing them altogether from some foods. The analysis of mineral elements requires a number of different techniques – some methods may be suitable for one food type yet completely unsuited to another. The Handbook of Mineral Elements in Food is the first book to bring together the analytical techniques, the regulatory and legislative framework, and the widest possible range of food types into one comprehensive handbook for food scientists and technologists. Much of the book is based on the authors’ own data, most of which is previously unpublished, making the Handbook of Mineral Elements in Food a vital and up-to-the-minute reference for food scientists in industry and academia alike. Analytical chemists, nutritionists and food policy makers will also find it an invaluable resource. Showcasing contributions from international researchers, and constituting a major resource for our future understanding of the topic, the Handbook of Mineral Elements in Food is an essential reference and should be found wherever food science and technology are researched and taught.
