## (B) Modeling Example

Determination of Exposure EECs Using the RS method: An Example

Example is for Almonds which is applied at a si ngle rate of 2 lbs a. i. /A (2.242 kg a.i/ha). Rates used in the simulations were 1.009 kg a.i/ha for α -endosulfan and 0.426 kg a.i/ha for β -endosulfan and 0.839 kg a.i/ha for endosulfan su lfate. All of th e three chemicals were assumed to be applied at time zer o. Three PRZM/EXAMS modeling runs were executed using PE-5:

The first modeling run gives 1-in-10 years exposure EECs for α -endosulfan as shown below:
