Rice, Hammitt, and Evans publish results from a probabilistic model describing the possible monetary benefits of reducing methyl mercury. The article, published in Environmental Science & Technology (volume 44, issue 13) estimates an additional $860 million with a 10% reduction in exposure to the US population.

Grady Hanrahan has complied a list of respected researchers to contribute to the text 'Modelling of Pollutants in Complex Environmental Systems, Volume II'. Included in the contents is a chapter entitled 'An Overview of Exposure Assessment Models Used by the US Environmental Protection Agency'.

This section is an extension and complement to exposurescience.org and is meant as a space for researchers developing, using, and generally interested in simulations applied to environmental health and exposure science. Theoretical concepts in statistics, stochastic processes, computational methods, and modeling frameworks are all topics of interest, as are applications of simulations in environmental health, human exposure assessment and analysis, pharmacokinetics, health risk, and environmental science.
