Title Exposure Science in the 21st Century: A Vision and a Strategy.

Abstract We are exposed every day to agents that have the potential to affect our healththrough the personal products we use, the water we drink, the food we eat, the soil and surfaces we touch, and the air we breathe. Exposure science addresses the intensity and duration of contact of humans or other organisms with those agents (defined as chemical, physical, or biologic stressors)1 and their fate in living systems. Exposure assessment, an application of this field of science, has been instrumental in helping to forecast, prevent, and mitigate exposures that lead to adverse human health or ecologic outcomes; to identify populations that have high exposures; to assess and manage human health and ecosystem risks; and to protect vulnerable and susceptible populations. Exposure science has applications in public health and ecosystem protection, and in commercial, military, and policy contexts. It is central to tracking chemicals and other stressors that are introduced into global commerce and the environment at increasing rates, often with little information on their hazard potential. Exposure science is increasingly used in homeland security and in the protection of deployed soldiers. Rapid detection of potentially harmful radiation or hazardous chemicals is essential for protecting troops and the general public. The ability to detect chemical contaminants in drinking water at low but biologically relevant concentrations quickly can help to identify emerging health threats, and monitoring of harmful algal blooms and airborne pollen can help to identify health-relevant effects of a changing climate. With regard to policy and regulatory decisions, exposure information is critical in budget-constrained times for assessing the value of proposed public-health actions.
