Failed or abandoned sparrowhawk eggs were taken from nests by licensed egg collectors and archived as part of the monitoring activities of the PBMS in the UK. The period studied was 1985 to 2007. Data are presented in three tables including detected PBDEs, interpolated PBDEs and sample properties which are described in a metadata file. The Predatory Bird Monitoring Scheme (PBMS) is a long-term, national monitoring scheme that quantifies the concentrations of contaminants in the livers and eggs of selected species of predatory and fish-eating birds in Britain.

Egg weight, length and breadth were measured and the eggs were then blown or cracked open. The shells were washed, air-dried and reweighed, while the egg contents were homogenised and stored in glass jars at -20 deg C until analysed. \n\nSamples were selected from the PBMS archive for PBDE analysis based on the criteria of covering the longest temporal period in eggs from the smallest possible geographical area, which was found to be the region of England directly east and within 250 km of the Welsh border. \n\nSampling years were determined by the availability of eggs in the archive, the criterion being that three to five eggs, each from a different nest, were available for analysis for each sampling year. There were sufficient eggs for ten sampling years that spanned the period 1985-2007. When more than one egg was available from any given nest, the egg for analysis was selected at random as laying order was not known.","metadataDate":"2026-06-29T17:16:07","notGEMINI":false,"onlineResources":[{"url":"https://data-package.ceh.ac.uk/data/5fdccbe5-066b-4130-8431-d6389c31cea2","name":"Download the
