Bioavailability of Pesticides in Soil
Angela R. Soemo
Dr. Barbara K. Kramer, Faculty Mentor

Bioavailability is defined as the amount of a contaminant that is available to be desorbed into systematic circulation where it can be harmful to the individual. In this case, we’re specifically looking at how much of a pesticide is bioavailable once it’s been in a soil matrix. A method developed by Ruby, et al called a Physiologically Based Extraction Test (PBET) has proven to be a fairly good estimate of this measurement based on previous experiments with animal models. However, this model squanders a large amount of time and space for the apparatus. Further studies have shown that an aqueous-based microwave extraction test gives similar, but not statistically equivalent, results. The goal of this research project is to develop a microwave assisted extraction test that will render statistically equivalent results to the PBET.
