Risk Assessment Model

Pesticides RIsks in the tropics to Man, Environment and Trade (Risk)
Decision Support System was developed to
estimate risks of pesticide use to organisms in soil,
groundwater, and surface water and to humans.
PRIMET is developed to be used in developing
countries, and is based on simplifications of
sophisticated approaches, such as TOXSWA and
PEARL. The risk assessment is expressed in Exposure
Toxicity Ratio's which are calculated by dividing the
predicted exposure by the safe concentration.
