The risk assessment tool WISPE (The World Integrated System for Pesticide Exposure) was developed which includes the environmental fate and transport models winPRZM and EXAMS. WISPE is a computer modelling tool developed to evaluate the potential impact of crop protection products on the environment in Norway. WISPE makes it possible to estimate pesticide exposure in surface- and groundwater resources considering Norwegian conditions for 11 different crops. Originally developed in 2013, WISPE was updated in 2021 to be more flexible with adding scenarios, outputs, weather files and to utilize the most recent enhancements to winPRZM. This version of WISPE also includes two northern FOCUS groundwater scenarios. This poster presents the new user input interface and shows examples of the results.
