Monitoring of contaminants in gannet eggs began in 1971.

Gannet eggs are collected biennially by licensed egg collectors from two colonies, Bass Rock in the Firth of Forth and Ailsa Craig in the Irish Sea, and from other sites when available. 

There has been a statistically significant decline in PCB congener sum concentrations in gannet eggs during the monitoring period of 1969-2009.
