Superfund Research Program
A Holistochastic Approach to Human Exposure Assessment
Project Leader: George Christakos
Grant Number: P42ES005948
Funding Period: 1995 - 2006
The work in project 7 during the past year has led to theoretical and computation advances in human health exposure modeling. These advances include the development of (i) novel physico-epidemiologic criteria of exposure-health effect analysis and (ii) Bayesian Maximum Entropy (BME) computational techniques for human exposure spatiotemporal mapping and risk assessment; as well as their application to several real world case studies (North Carolina temperature exposure-mortality association, east US population risk assessment, prediction of environmental fate and transport in the subsurface, etc.). The development of the BME computational library provides a powerful practical tool for human exposure modeling and S/T mapping, and it is leading to a new book under contract with Springer-Verlag to be published in early 2001.
