Book Description
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.

Publisher: National Academies Press
ISBN: 0309453518
Category : Nature
Languages : en
Pages : 201

Book Description
Over the last decade, several large-scale United States and international programs have been initiated to incorporate advances in molecular and cellular biology, -omics technologies, analytical methods, bioinformatics, and computational tools and methods into the field of toxicology. Similar efforts are being pursued in the field of exposure science with the goals of obtaining more accurate and complete exposure data on individuals and populations for thousands of chemicals over the lifespan; predicting exposures from use data and chemical-property information; and translating exposures between test systems and humans. Using 21st Century Science to Improve Risk-Related Evaluations makes recommendations for integrating new scientific approaches into risk-based evaluations. This study considers the scientific advances that have occurred following the publication of the NRC reports Toxicity Testing in the 21st Century: A Vision and a Strategy and Exposure Science in the 21st Century: A Vision and a Strategy. Given the various ongoing lines of investigation and new data streams that have emerged, this publication proposes how best to integrate and use the emerging results in evaluating chemical risk. Using 21st Century Science to Improve Risk-Related Evaluations considers whether a new paradigm is needed for data validation, how to integrate the divergent data streams, how uncertainty might need to be characterized, and how best to communicate the new approaches so that they are understandable to various stakeholders.

Exposure Assessment in Occupational and Environmental Epidemiology

Exposure Assessment in Occupational and Environmental Epidemiology PDF Author: Mark J. Nieuwenhuijsen
Publisher: OUP Oxford
ISBN: 0191015687
Category : Medical
Languages : en
Pages : 298

Book Description
Set against a background of growing public, media and political concern about occupational and environmental health issues, and a scientific need to better understand and explain the effects of pollutants on human health, this book is a unique resource. Contributions from an expert panel of international practitioners provide a comprehensive reference on the state of the art methods and applications in the field of occupational and environmental pollution and the adverse health effects, particularly the exposure assessment in epidemiological studies. Risks associated with occupational and environmental exposure are generally small, but the exposed population, and hence the population attributable risk, may be large. To detect small risk, the exposure assessment needs to be very refined. Exposure assessment is the study of the distribution and determinants of potentially hazardous agents, and includes the estimation of intensity, duration and frequency of exposure, the variation in these indices and their determinants. The aim of this book is to develop an understanding and knowledge of exposure assessment methods and their application to substantive issues in occupational and environmental epidemiology. The emphasis is on methodological principles and good practice. It is focused on exposure assessment in both occupational and environmental epidemiology since there are many similarities but also some interesting differences. The book outlines the basic principles of exposure assessment, and examines the current status and research questions in the exposure assessment of occupational and environmental epidemiological studies of allergens, particulate matter, chlorination disinfection by-products, agricultural pesticides and radiofrequencies. The book will be of interest to all concerned with exposure assessment and epidemiology. It will be a valuable source for undergraduate and postgraduate courses in exposure assessment, occupational hygiene, environmental science, epidemiology, toxicology, biostatistics, occupational and environmental health, health risk assessment and related disciplines and a useful resource of reference for policy makers and regulators.

Book Description
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.

Book Description
The Council of the North Atlantic Treaty Organization (NATO) established the "Committee on the Challenges of Modern Society" (CCMS) in 1969. The CCMS was charged with developing meaningful environmental and social programmes for solving existing problems and developing long-range goals for environmental protection. In 1983, at the Fall Plenary of the CCMS, the Norwegian delegate Dr. H.C. Christensen, proposed a Pilot Study on "Risk Management of Chemicals in the Environment". A draft proposal, written by Dr. Kari Kveseth of the Center for Industrial Research in Oslo, was presented. Dr. Christensen also informed the participants at the meeting that Norway was willing to act as the Pilot Country. The project was initially planned for 3 years, but it was later extended through 1987. The inaugural meeting was held in Oslo in April 1984 with participants from Denmark, Greece, France and Italy, in addition to representatives from several Norwegian institutions. The attendees concluded that a Pilot Study, as delineated in the draft proposal, would be useful, and it was decided to work out a detailed project plan based on the proposal.
