For decades, we have observed a major biodiversity crisis impacting all taxa. Avian species
have been particularly well monitored over the long term, documenting their declines. In …

Biomonitoring using raptors as sentinels can provide early warning of the potential impacts
of contaminants on humans and the environment and also a means of tracking the success …

Biomonitoring using birds of prey as sentinel species has been mooted as a way to evaluate
the success of European Union directives that are designed to protect people and the …

Persistent halogenated compounds (PHCs), such as dichlorodiphenyltrichloroethane and its
metabolites (DDTs), hexachlorocyclohexane isomers (HCHs), polychlorinated biphenyls …

Feathers have many advantages that make them an excellent nondestructive tool for
monitoring polyhalogenated compounds (PHCs). This paper proposes a review on the …

To date, information is scarce on the accumulation and potential risks of persistent
chlorinated and fluorinated contaminants in birds. In this study, organohalogen …

Triazole compounds are among the most widely used fungicides in agroecosystems to
protect crops from potential fungal diseases. Many farmland birds spend a significant part of …

Initial studies on the pressure from environmental contaminants on raptor populations in
Spain date back to the 1980s, and they have been carried out from a range of viewpoints …

Organochlorine (OC) pesticides were widely used on the Canary Islands (Spain) for
intensive crop production and against plagues of African locust. A previous study performed …

The exposure to persistent pollutants such as organochlorine compounds (OCs) or metals
has been associated with declines in top predator populations, which can accumulate high …
