RIVM Report 601516015
A model has recently been developed at RIVM to predict the effects of variable exposure to pesticides of plant and animal populations in surface water. Before a pesticide is placed on the market, the environmental risk of the substance has to be assessed. This risk is estimated by comparing the exposure of plants and animals to the pesticide with the expected sensitivity of these plants and animals to the particular pesticide. The model presented here consists of a combination of two models: one describing the development of a population and one combining the variable exposure with growth and survival of plants and animals. This combination offers a practical solution to the problem that it is not possible to study all stages and all exposure regimes in the laboratory. Separate from the model itself, indications are given about the data needed to use the model.
