ABSTRACT
Calculating pesticide residue levels in feed items for terrestrial species requires accounting for the application rate of the pesticide, the frequency and interval of application, the half-life of the pesticide on the food item, and the residue unit dose. Microsoft Excel™-based applications such as the US Environmental Protection Agency's Terrestrial Residue Exposure model (T-REX) and Terrestrial Herpetofaunal Exposure Residue Program (T-HERPS) calculate the residue levels in feed items using a recursive sequence. A recursive sequence is an unwieldy calculation method that presents a barrier to creating a software-based tool capable of conducting flexible assessments. Therefore, we determined the closed form of the recursive mathematical equation used by both T-REX and T-HERPS. With this formula, we can both duplicate screening-level assessments (T-REX, T-HERPS) as well as incrementally refine the assessment with data-driven inputs.
