Assessment of persistent organic pollutants and their relationship with immunoglobulins in blood of penguin colonies from Antarctica

ABSTRACT: Persistent organic pollutants (POPs) may affect the immune system of seabirds, and some field studies have examined this effect. There are evidences that POPs cause negative effects on the immune system, but in Antarctic penguins data are scarce. In order to assess the risks that POPs may...
