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.

Grimm et al. (2019) Bats, birds & shrews in environmental risk assessment
Bats are not specifically considered in pesticide risk assessments. The implicit assumption is that bats are covered by the current avian or mammalian risk assessment scheme according to EFSA (2009) which focusses on birds and mammals, such as rodents, shrews and lagomorphs.

Lückmann et al. (2019) Chronic oral exposure of adult honey bees to PPPs: sensitivity and impact analysis of EFSA Bee GD
In 2013 the European Food Safety Authority (EFSA) published a guidance document (GD) on the risk assessment of plant protection products on bees, which intended to provide guidance for notifiers and authorities in the context of the review of plant protection products (PPPs) and their active substances under Regulation (EC) 1107/2009 (EC 2009).

Amossé, Henkes (2019) Assessing the effects of plant protection products on enchytraeids under field conditions: test of carbendazim as a toxic reference
According to the Scientific Opinion addressing the state of the science on risk assessment of plant protection products for in-soil organisms (EFSA PPR Panel, 2017), Specific Protection Goal options have been identified for different groups of soil organisms.

Ibrahim et al. (2019) A common issue Wildlife risk assessment supported by population modelling: a case study on potential herbicide effects on common vole populations
Environmental risk assessments ( for pesticides usually require higher tier data for the small herbivorous mammal scenario represented by the vole. Population modelling for a relevant vole species is one way to provide such data. This exemplarily case study conveys all relevant steps conducted in a population modelling application for higher tier ERA within a submission process.

Katzschner et al. (2019) Accuracy of GPS tag tracking for wildlife risk assessment relevant field scenarios the current situation
Automatic acquisition of detailed animal movement data via GPS tags is nowadays a common scientific method and is still evolving. The main requirement of monitoring data intended for regulatory risk assessments is the continuous (or at least minute based) recording of the exact position of tagged individuals in the agricultural landscapes.

Ludwigs et al. (2019) Calculating realistic long term PT values for wildlife risk assessment insights from telemetry field studies
The current EFSA guidance document (GD) on risk assessment for birds and mammals (2009) assumes, if no specific data are available, that animals feed exclusively on pesticide treated fields.

Hahne et al. (2019) New proposed Residues on Fruits (RUD’s) for frugivorescenarios in EFSA Bird and Mammal Risk Assessment
The Guidance Document on Risk Assessment for Birds and Mammals (EFSA 2009) provides default ‘Residue per unit dose’ or RUD values for food items to be used in wild life risk assessments. Most of these RUD values are based on large numbers of registration relevant residue studies conducted by industry members and provided to EFSA.

Lückmann, Faupel, Ludwigs (2018) ‘Focal species’ – can this well-known concept in higher-tier risk assessments be an appropriate approach for solitary bees?
Bumble bees and solitary bees have to be considered in addition to honey bees regarding environmental pollinator risk assessments. For solitary bees it is proposed to use Osmia cornuta (LATR., 1805) or O. bicornis (L., 1758) as test organisms.

Sgolastra et al. (2018) Pesticide Exposure Assessment Paradigm for Solitary Bees
Current pesticide risk assessment for bees relies on a single (social) species, the western honey bee, Apis mellifera L. (Hymenoptera: Apidae). However, most of the >20,000 bee species worldwide are solitary.
