Klein et al. (2022) Results of Ring‐Testing of a Semifield Study Design to Investigate Potential Impacts of Crop Protection Products on Bumblebees (Hymenoptera, Apidae) and a Proposal of a Potential Test Design
In Europe, the risk assessment for bees at the European Union or national level has always focussed on potential impacts on honeybees. During the revision of the European Food Safety Authority bee guidance it was explicitly stated that bumblebees and solitary bees should be considered as well and consequently concerns were raised regarding the representativeness of honeybees for these other bee species.

Ludwigs et al. (2022) Assessing the Portion of Diet Taken by Birds and Mammals from a Pesticide‐Treated Area—Proposal for a Joint Way Forward
An environmental risk assessment for birds and mammals is an important part of any application package for potential registration of pesticides in Europe. A realistic estimation of the exposure of a certain species to the pesticide under field conditions is a refinement factor in long‐term higher‐tier risk assessments.

Nickisch et al. (2022) Fish Species Sensitivity Ranking Depends on Pesticide Exposure Profiles
In the regulatory environmental risk assessment of plant protection products, the exposure tested in standard toxicity tests assumes simple exposure dynamics, such as constant exposure at the first stage of testing. However, environmental exposure can be highly dynamic.

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).

Lückmann, Kaiser, Blankenhagen (2020) Precision farming – consideration of reduced exposure in the pollinator risk assessment
Observed declines in the distribution and abundance of various insect species have moved the topic of biodiversity and the protection of honey bees, an insect species of particular economic interest, into the focus of public attention. This also resulted in an increasing public pressure to reform the European agricultural policy and as part of this to minimise the amount of synthetic plant protection products used.

Mair et al. (2020) The Minimum Detectable Difference (MDD) Concept for Establishing Trust in Nonsignificant Results: A Critical Review
Current regulatory guidelines for pesticide risk assessment recommend that nonsignificant results should be complemented by the minimum detectable difference (MDD), a statistical indicator that is used to decide whether the experiment could have detected biologically relevant effects.

Schabacker et al. (2020) Residue Levels of Pesticides on Fruits for Use in Wildlife Risk Assessments
The guidance document on risk assessment for birds and mammals (GD) provides generic residue values of pesticides on potential diet items for use in wildlife risk assessments. For most diet items, these values are based on a large number of residue studies.

Schimera et al. (2020) Consideration of nectarivorous birds in wildlife risk assessments
In subtropical and tropical climate zones where crops exhibit a flowering phase before harvest, nectar-feeding birds (see table) may be attracted to crop flower nectar. We present points to consider on whether and how a nectarivorous avian scenario might be included in higher tier environmental risk assessment (ERA) for plant protection products (PPPs) and what data would be needed.

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.
