Lutzmann, Vogel, Böhme (2012) Are the Mediterranean chameleon species possible focal species for risk assessments for PPPs in Southern Europe?
According to the new data requirements under the EU regulation 1107/2009, reptiles come into question regarding risk assessments of plant protection products (PPP). Although no specific data requirements on reptiles are stipulated in the respective EU documents some toxicity data are available in the open literature. These data are intended to be used in the risk assessment.

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) .

Körner et al. (2012), Relevant snakes and turtle species for the risk assessment of plant protection products in Northern and Central Europe
According to the new data requirements under the EU regulation 1107/2009, reptiles come into question regarding risk assessments of plant protection products (PPP). Although no specific data requirements on reptiles are stipulated in the respective EU documents (e.g. SANCO 11802/2010/rev July 2010), some toxicity data are available in the open literature.

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.

Gericke, Nekovar, Hörold (2010), Estimation of Application Dates of Plant Protection Products for Environmental Fate Modelling Based on Phenological Stages of Crops
According to the EU directive 91/414/EEC potential environmental concentrations of pesticides have to be assessed with environmental fate models. For the calculation of pesticide concentrations it is necessary to provide an application date which has to match the specific BBCH stage at which the pesticide shall be applied.

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.

Höller, Norman, Riffel (2007), Novel approaches in monitoring effects of pesticide products on wild small mammals
A field experiment was conducted in Southwest France where small mammal populations were monitored in azinphos-methyl (OP insecticide) treated pome fruit orchards. Small mammal abundance within the orchards was regularly measured by live trapping which followed a Capture-Mark-Recapture design.

Ludwigs et al. (2007), Comparison of dehusking experiments of laboratory mice and wild Apodemus spec. mice
Concerning treated seeds, dehusking behaviour (the peeling of seeds before ingestion) of small mammals may reduce exposure to pesticides used as treated seeds. The active substance is mainly located on the husk and therefore dehusking can reduce the amount of active substance ingested.

Schwarz, Norman, Riffel (2007), Novel approaches in monitoring effects of pesticide products
A field experiment was conducted in Southwest France and Northern Italy to investigate potential impacts of azinphos-methyl (OP insecticide) applications in pome fruit orchards on the natural bird community.

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.

Wang, Grimm (2007), Modelling of Home Range Dynamics for the Estimation of Population-Level Impacts in an Individual-Based Model of the Common Shrew (Sorex Araneus)
Probabilistic models have recently been introduced into risk assessment methodology for plant protection products, which marks a first step into a scientific evaluation of effects, their probability and magnitude. When it is probable that an effect occurs, the next logical step in risk analysis is to evaluate which impact that effect might have on local populations of focal species.
