Chemical pollution gets to Antarctic marine bird colonies

[font size=3]Latitude is the main factor which determines the organic pollutant concentration in Antarctic giant petrels –emblematic species in the Antarctic and sub-Antarctic regions-, according to an article from the journal Environmental Research in which Professor Jacob González Solís, from the Department of Evolutionary Biology, Ecology and Environmental Sciences and the Biodiversity Research Institute of the University of Barcelona (IRBio) takes part.
The research, directed by experts of the Institute of General Organic Chemistry (IQOG-CSIC), analyses the impact by persistent organic pollutants (COP) –toxic compounds with a high permanency on the environment which bio-accumulate in organisms- on oceanic birds present in areas of different latitudes in the Antarctic Ocean.
Northern giant petrels (Macronectes halli) and southern ones (M. giganteus) are the great scavengers in sub-Antarctic and Antarctic environments, and they have an extreme life strategy based on a long longevity and low fecundity (an only egg per each reproductive period). They are widely distributed in the southern ocean and can cover thousands of kilometres to feed themselves, but their population are highly vulnerable to any threat affecting their adult survival.

Albatross and giant petrels are the ocean birds with more exposure to mercury pollution in Antarctic and sub-Antarctic environments, according to another study by González Solís (Environmental Pollution, 2016).
