Analysis of Persistent Organic Pollutants in Silver Gull Eggs Using the Scion™ TQ GC-MS/MS System

The use of whole seabird egg for environmental contaminant testing is well established. In this study, the levels of organochlorine pesticides (OCPs), a significant group of persistent organic pesticides (POPs), were investigated in the eggs of silver gulls. Egg samples were initially separated into individual yolk, albumen and eggshell components, subsequently measured and freeze-dried. The components were extracted using a modified QuEChERS method.
