Kunz et al. (2024) Extraction Efficiency for Food and Feed
Extraction methods can vary greatly in their efficiency to extract so-called incurred residues that form when plant protection products are applied to agricultural crops. Active substances and their metabolites can be incorporated into food or feed crops, and thus may occur in tissues and animal products.

Laucht et al. (2024) Ornamental Phoenix palm trees as habitat for fauna in the Mediterranean Region – results from a full year monitoring
In the European Mediterranean Region, palm trees are a common element in cities and semi-urban landscapes and have become important habitat structures for local fauna. This study aimed to monitor the invertebrate and vertebrate fauna occurring on and associated with ornamental palms of the genus Phoenix, over the course of one year.

Bauer et al. (2023) A Toxicokinetic–Toxicodynamic Modeling Workflow Assessing the Quality of Input Mortality Data
Toxicokinetic–toxicodynamic (TKTD) models simulate organismal uptake and elimination of a substance (TK) and its effects on the organism (TD). The Reduced General Unified Threshold model of Survival (GUTS‐RED) is a TKTD modeling framework that is well established for aquatic risk assessment to simulate effects on survival.

Faupel et al. (2023) Precision farming and environmental pesticide regulation in the EU—How does it fit together?
Precision farming technology allows pesticides to be applied precisely to the target while leaving the rest of the field untreated. In the regulation of pesticides, however, a homogeneously sprayed field is considered as the standard scenario.

Wittwer, Jakoby (2023) Evaluation of wind speed measurements published by th German Meteorological Service (DWD) for the years 2004 to 2020
Sowing of seeds treated with agrochemicals is common practice in agriculture. German regulatory authorities are requesting that seeds treated with plant protection products must not be sown at average hourly wind speeds exceeding 5 m/s (at 2 m above ground) unless the environmental risk assessment indicates a large margin of safety.

Singer, Nickisch, Gergs (2022) Joint survival modelling for multiple species exposed to toxicants
In environmental risk assessment (ERA), the multitude of compounds and taxa demands cross-species extrapolation to cover the variability in sensitivity to toxicants. However, only the impact of a single compound to a single species is addressed by the general unified threshold model of survival (GUTS).

Sur, Herrmann (2022) Determination of transfer factors for solute concentrations from agricultural fields to drinking water abstraction points
The stepwise attenuation of solute concentrations has been determined, starting from the unsaturated zone underneath treated fields across the deeper aquifer, down to drinking water abstraction wells. The partial or overall transfer or attenuation factor may help to make informed decisions on the magnitude of the decrease in concentrations from shallow leachate to drinking water abstraction, which is largely caused by mixing.

Herrmann, Sur (2021) Natural attenuation along subsurface flow paths based on modeling and monitoring of a pesticide metabolite from three case studies
Groundwater—especially for the use as drinking water—is a strictly protected resource in the existing guidelines for pesticide registration and drinking water protection in the EU.

Klopper et al. (2020) How to reduce computation effort for GUTS modelling while retaining output reliability for risk assessment use?
The practicability of approaches can influence their usability in environmental risk assessment (ERA). The anticipated 20- year data in aquatic RA would considerably amplify computational effort and therefore pose a challenge for General Unified Threshold Model of Survival (GUTS) applications in ERA.

Lückmann et al. (2020) Precision pesticide application as a tool to reduced exposure of crop visiting pollinators?
Recent publications on severe declines of insects moved the topic of biodiversity in agricultural landscapes into the focus of public attention. Consequently, European policy is under increasing public pressure to minimize the amount of synthetic pesticides applied and to reform the criteria for their authorization and use.

Ludwigs et al. (2019) Response to David R. Crocker and Steven D. Langton “When Is It Legitimate to Downplay Individual Differences?”
In their letter, Crocker and Langton (2019) critically discuss the approach of 21‐dMonte Carlo PT (portion of diet from a pesticidetreated area) simulations proposed in Ludwigs et al. (2017). The aim of this method is to assess realistic 21‐d PT values by including daily variability in habitat use for individual animals.
