Exposure assessments are indispensable for the conduct of effective risk assessments, for the success of epidemiologic research, for the surveillance of environmental and health stresses in populations and ecosystems, and for development and evaluation of the efficacy of risk management activities.

Risk management, in fact, almost invariably relies on management of exposures. As the attached report indicates, however, anticipated developments in both the near-term and the long-term offer significant possibilities for advancement in exposure assessment capabilities in the areas of databases of exposure and exposure-related information, personal sampling technologies e.

By embracing a leadership role in catalyzing advances in these areas, the Agency can create new capabilities that would allow it to more credibly model population exposures from sources through health risks in support of its risk assessments and risk management activities. The contents of this database must match the data needs for modeling environmental fate and transport, for conducting exposure-dose assessments, and for surveillance of environmental and health effects in populations and ecosystems, and as measures of exposure control efficacy.

In summary, we believe that an increased recognition of the importance of the exposure paradigm as a fundamental approach for early identification of environmental stresses and the human health and ecological problems they may cause is necessary within EPA in order to effectively and efficiently prevent the occurrence of adverse effects.

To this end, we strongly recommend the adoption of the above recommendations. The Board is structured to provide balanced, expert assessment of scientific matters related to problems facing the Agency. This report has not been reviewed for approval by the Agency and, hence, the contents of this report do not necessarily represent the views and policies of the Environmental Protection Agency, nor of other agencies in the Executive Branch of the Federal government, nor does mention of trade names or commercial products constitute a recommendation for use.

The titles are listed below: The Committee noted that early recognition of the nature and extent of potentially adverse exposures could be of immense benefit in avoiding adverse effects to public health and ecological systems.

Opportunities for advancement were noted in key areas of microsensor and microprocessor technologies, the development and understanding of biomarkers of exposure, and the expansion of federal and industry databases on human exposures to toxic substances in the work place and at home.

They encourage the Agency to develop integrated research programs to track and apply these developments to monitoring and assessment models, to work constructively to improve and validate exposure assessment models, to collaborate widely with governments and industry, to promote improvements in databases, and employ interdisciplinary teams to address exposure problems.

The Committee anticipates that the importance of the exposure paradigm will increase significantly in the future, leading to a combined approach for human health and ecological resource protection.

Edward Bender provided staff support to complete this report. Historical Development 8 2. The objective of the Project was to produce reports and guidance to help EPA improve its readiness to anticipate problems and to develop and implement an appropriate strategy for the protection of human health and the environment now and in the future.

The Indoor Air and Total Human Exposure Committee IAQTHEC focused its report on anticipated future developments in the science of exposure assessment, and how these developments can be advanced and harnessed to help EPA and the nation achieve substantial risk reductions related to environmental hazards.

For the near-term, i.

For the longer-term, i. Advances in exposure assessment will help to provide a sound scientific basis for ranking environmental risk and for developing effective risk management policies. The weaknesses that are highlighted include the severe weaknesses of the currently available databases containing exposure and exposure-relevant data, the reliance by EPA on exposure assessments based on numerous assumptions which have been proven incorrect, or are not supported by common experience and systematic verification by direct observation, and the current fragmentation and lack of coherence of available models for different media, pathways, chemicals, etc.

Chapter Four focuses on developments and prospects for improvements in exposure assessment in five areas: The report emphasizes the need for more comprehensive exposure databases and outlines four steps that should be taken: Targeted surveys and improved uses of regulatory compliance data are identified as two complementary technical approaches to meet some of the above goals.

In the area of personal samplers and monitors, the report highlights the need to obtain measures of breathing rates or exercise patterns concurrent with air measurements, the need to develop personal monitoring devices for dermal exposures, and the need for techniques to obtain better information about contaminant ingestion.

Biomarkers of exposure and of response are discussed as future tools for exposure assessment that will be technically valuable yet ethically thorny. Major advances in questionnaire technology are described as requiring substantial improvements in applications of behavioral science, although increasingly automated methods involving computer and video administration can be anticipated for collecting useful data on personal activities.

Finally, the chapter emphasizes the need to validate exposure models, to link multiple models into comprehensive integrated models, and to improve the efficacy of models as tools for prioritizing the major routes and media of concern.

Chapter Five presents a number of findings. First, the report uses some emerging issues for which improved exposure measurement techniques are needed, i. Using the inhalation route as an example, the report discusses a number of areas where substantial progress in monitoring capabilities can be anticipated, including passive monitors, electrochemical sensors, and optically-based particle sensors.View Professor Prashant Kumar’s profile on LinkedIn, the world's largest professional community.
