The value of the species sensitivity distribution concept for predicting field effects: (non-)confirmation of the concept using semifield experiments

The aim of the study is: 1) to substantiate the role of uncertainties and assumptions within the SSD concept 2) to derive scientific conclusions on various aspects of the SSD concept 3) to express the limitations and points of concern regarding the use of the SSD-based extrapolation procedure in the derivation of environmentakl quality criteria and ecological risk assessment
