Levels of several organohalogenated pollutants, such as p,p-DDE, HCB, CHLs and PCBs, were 10 to 100-fold higher in soil samples collected from penguin colonies than in soil from reference areas. This is likely related to local penguin activity, such as a higher abundance of guano and the presence of bird carcasse. While background contamination of the Antarctic region is mostly explained by the long-range atmospheric transport, this paper suggests that bird populations contribute also substantially to the local redistribution of contaminants.
