Seiterle-Winn, Hörold (2012) Impact of the Rainfall Criterion in the EFSA Soil Persistence Guideline on Kinetic Evaluation of Field Degradation Trials
In 2010 the EFSA published a new guidance on soil persistence for the derivation of field half lives of pesticides with the aim to exclude loss processes at the soil surface (i.e. photolysis, volatilisation) .

Wang, Erzgräber, Gottesbüren (2010), EPAT – An Exposure Pattern Analysis Tool
The behaviour of pesticides in water bodies adjacent to a single field is calculated for the registration in the EU with the surface water model FOCUS TOXSWA. The calculated pesticide concentrations in the water and sediment layer describe the exposure over time, which is typically characterized by rather short exposure peaks.

Wang, Wolf (2008), A Probabilistic Model for Estimating the Exposure and Effects After Spray Application in Real Landscapes
In current risk assessments for plant protection products applied via spray application, default drift-values are used which are based on a large number of field trials conducted by Ganzelmeier et al. and Rautmann et al.

Wang, Nikolakis, Wolf (2007), Reduction of Unvertainty in Chroni Avian Risk Assessments for Granular Organophosphate-Nematicides by the Use of Field Exposure Data and Probabilistic Risk Evaluation
First tier deterministic chronic avian risk assessments for organophosphate nematicides often indicate a high theoretical long-term risk to birds due to the generally high intrinsic toxicity of these compounds in conjunction with high application rates.
