Research interests

My research group is interested in organic chemicals in the environment.  We quantify these chemicals in soils, sediment, fish, macroinvertebrates, plants, water, and air.  We aim to understand how these chemicals move around in the environment, what we can learn from them, and what their impacts might be.  For this research, we primarily focus on current-use pesticides, brominated flame retardants, polycyclic aromatic hydrocarbons and persistent organic pollutants. To better understand the fate of these chemicals, we conduct field work (often in remote locations), perform laboratory experiments (e.g. measurement of partition coefficients), and use chemical fate models.  We also quantify organic biomarkers, such as alkanes and alkenones, in marine and lake sediments and by working with paleogeologists, use these chemicals to gain information about past climates.

Pesticide volatilisation model

A user-friendly version of our model for predicting the volatilisation of pesticides from agricultural soils is available for download.  This model has been described in detail in the following publication: 

Davie-Martin, C.L., Hageman, K.J, Chin, Y.P.  An improved screening tool for predicting volatilization of pesticides applied to soils (2013).  Environmental Science and Technology, 47, 868-876. 

NOTE: In February 2016, we updated the user interface to include a new, more robust equation for predictions of pesticide Ksoil-air values, whose derivation is described in the following publication: Influence of temperature, relative humidity, and soil properties on the soil-air partitioning of semivolatile pesticides: Laboratory measurements and predictive models (2015). Davie-Martin, L., Hageman, K.J., Chin, Y.-P., Rougé, Fujita, Y. Environmental Science and Technology 49, 10431-10439.

If you would like access to the model version that uses the original equation for predicting Ksoil-air, contact Kimberly Hageman by e-mail.

Access is free although you will be asked to provide your name and institution.
