Data comprise concentrations of second-generation anticoagulant rodenticides (SGARs) in Eurasian sparrowhawk (Accipiter nisus) livers found dead in Great Britain between 1995 and 2015. The liver SGARs measured include Bromadiolone, Difenacoum, Brodifacoum, Difethialone, Flocoumafen and sum of SGARs in nanograms per gram-wet weight. The data also include demographic information (Age and Sex) for each bird and location where the bird was found.

Members of the public and other interested parties submitted Sparrowhawks to the Predatory Bird Monitoring Scheme (PBMS) after being found dead. The collection, examination, and archiving of birds and their tissues was conducted by the PBMS and supported by the Natural Environment Research Council award number NE/R016429/1 as part of the UK-SCAPE programme delivering National Capability. Contaminants and data analysis was conducted under the CHEMPOP project, NERC grant NE/S000100/1. The UKAS Accredited UK Centre carried out liver analysis for Ecology & Hydrology Lancaster Analytical Chemistry Facility.

Provenance & quality

Dead sparrowhawks were submitted to the Predatory Bird Monitoring Scheme and frozen. Necropsies were carried out on each bird in which tissue samples were taken and stored at -20C prior to chemical analysis. Macroscopic observations were recorded to determine age and sex of the bird. Chemical analysis to determine rodenticide concentrations were performed by UKAS accredited Laboratories. Gloria Pereira Head of Centralised Chemistry performed quality assurance of the resulting data.

Chemical, provenance and necropsy data were collated by Richard Broughton and quality assured by Lee Walker in laboratories conforming to JCOPr.
