“…Given that the hedgehogs' natural diet includes vertebrate cadavers [20][21][22][23][24], scavenging on poisoned rats and mice is not an uncommon behaviour for hedgehogs, potentially causing secondary poisoning with rodenticides. Furthermore, hedgehogs may also scavenge on carcasses of predatory species preying on rodents or ingest rodenticide pellets directly, if these are accessible to the hedgehogs in, e.g., bait boxes with holes large enough to fit a hedgehog head or by spreading the pellets directly on the ground [79][80][81]. Rodenticides are also detected in non-target invertebrates such as beetles and slugs [82,83], which constitute a considerable proportion of the natural diet of hedgehogs [22,23].…”

Monitoring data from several European countries indicate that European hedgehog (Erinaceus europaeus) populations are declining, and research exploring the causes of the decline, including exposure to potentially harmful xenobiotics and metals, may inform conservation initiatives to protect this species in the wild. Hedgehogs are ground-dwelling mammals, feeding on a range of insects, slugs, snails, and earthworms, as well as eggs, live vertebrates, and carrion, including carcasses of apex predator species representing higher levels of the food chain. Consequently, hedgehogs come into close contact with contaminants present in their habitats and prey. This review investigated the studies available on the subject of the occurrence of metals and organic xenobiotics in hedgehogs. This study found that a vast range of different pesticides; persistent organic pollutants (POPs), including organochlorine compounds and brominated flame retardants (BFRs); as well as toxic heavy metals could be detected. Some compounds occurred in lethal concentrations, and some were associated with a potential adverse effect on hedgehog health and survival. Due to their ecology, combined with the opportunity to apply non-invasive sampling techniques using spines as sampling material, we suggest that the European hedgehog is a relevant bioindicator species for monitoring the exposure of terrestrial wildlife to potential toxicants in urban and rural environments.

“…There are established methods to demonstrate the relevance of effects with population models to extrapolate from the laboratory to the field (e.g., Wang ; Liu et al ; Schmitt et al ; Topping and Elmeros ; Topping and Weyman ). Mintram et al () reviewed modeling approaches potentially applicable to the environmental risk assessment of endocrine‐active substances in fish and concluded that individual‐based models (IBMs) are a particularly useful model type because they can account for species‐specific traits and behaviors (e.g., breeding behaviors) and simulate interorganism interactions and organism–environment interactions (including responses to chemical exposure).…”

The European Commission intends to protect vertebrate wildlife populations by regulating plant protection product (PPP) active substances that have endocrine‐disrupting properties with a hazard‐based approach. In this paper we consider how the Commission's hazard‐based regulation and accompanying guidance can be operationalized to ensure that a technically robust process is used to distinguish between substances with adverse population‐level effects and those for which it can be demonstrated that adverse effects observed (typically in the laboratory) do not translate into adverse effects at the population level. Our approach is to use population models within the adverse outcome pathway framework to link the nonlinear relationship between adverse effects at the individual and population levels in the following way: (1) use specific protection goals for focal wildlife populations within an ecosystem services framework; (2) model the effects of changes in population‐related inputs on focal species populations with individual‐based population models to determine thresholds between negligible and nonnegligible (i.e., adverse) population‐level effects; (3) compare these thresholds with the relevant endpoints from laboratory toxicity tests to determine whether they are likely to be exceeded at hazard‐based limits or the maximum tolerated dose/concentration from the experimental studies. If the population threshold is not exceeded, then the substance should not be classified as an endocrine disruptor with population‐relevant adversity unless there are other lines of evidence within a weight‐of‐evidence approach to challenge this. We believe this approach is scientifically robust and still addresses the political and legal requirement for a hazard‐based assessment.

“…Bromadiolone, applied in the form of coated cereal grain baits has been allowed in Spain as a PPP until 2014 and approved exceptionally in Castilla y León during the years 2016-2017 (Junta de Castilla y León, 2016; Lauret et al, 2020). Currently, bromadiolone use continues as a biocide for domestic control of rodents in buildings and within farmhouses or barns, and exposed rodents may be eventually available for small mustelids in the surroundings (Coeurdassier et al, 2018;Topping and Elmeros, 2016).…”
