Ecological parameter: SPEAR pesticide

Parameter group: habitat related parameters

Explanation:
The taxa are divided into sensitive species ("SPEcies At Risk") and insensitive species ("species not at risk") based on their ecological properties. The ecological properties used are: physiological sensitivity to organic pollutants, generation time, exposure in the water body at the time of maximum insecticide application and ability to migrate from refugia.
