A world group with the participation of researchers from the Nationwide Museum of Pure Sciences (MNCN-CSIC) has analyzed the feces of three species of Antarctic penguins –the Adelia (Pygoscelis adeliae), the chinstrap (Pygoscelis antarcticus) and the papua (Pygoscelis papua– and has discovered giant quantities of microplastics, What polyester Y polyethylene, amongst different particles of non-natural origin.
The truth that penguins are predators make them good indicators of the well being of the ecosystems during which they dwell
Andrés Barbosa, from the MNCN
The target of the research, printed in the journal Science of the Complete Setting, was to investigate the presence of microplastics in the antarctic peninsula and in the scotia sea, southeast of Argentina, given the nice ecological significance of these habitats.
“Penguins are used for a lot of research as a result of their biology and ecology are well-known and the incontrovertible fact that they’re predators makes them good indicators of the well being of the ecosystems during which they dwell,” he explains. Andres Barbosa, scientist at the Nationwide Museum of Pure Sciences (MNCN-CSIC) and writer of the work.
The research, which has included researchers from Portugal, the United Kingdom and Spain, emphasizes the must know the results of these particles in Antarctic fauna and to determine more practical measures to regulate the contamination by plastics and different particles of human origin on the frozen continent.
The lengthy life of plastics
Microplastics are particles of lower than 5 mm which are more and more widespread in marine ecosystems, one thing worrisome given their persistence in the surroundings, the place they will final for greater than 50 years, and their eventual accumulation in marine ecosystems. Trophic chains. “These pollution attain seas and oceans primarily by the trash and waste from anthropic actions “, he explains Barbosa.
Microplastics can final in the surroundings for greater than 50 years, accumulating in meals chains
“Given the low human presence in the Antarctic Ocean and Antarctica, low contamination by microplastics can be anticipated in these areas. Nevertheless, analysis stations, fishing and vacationer boats and ocean currents trigger these particles to succeed in these habitats, which might trigger a excessive focus at the native degree ”, he says. Jose Xavier, researcher at the College of Coimbra (Portugal).
“The outcomes present that the diet of the three species consists of totally different proportions of antarctic krill (Euphausia superba), 85% in the case of the Adélie penguin; 66% in the chinstrap and, lastly, 54% in the Papua. Microplastics have been present in 15%, 28% and 29% of the samples, respectively, in the three species studied ”, he factors out. Joana Fragão, from the College of Coimbra.
“The frequency of look of these substances it was comparable in all colonies, which leads us to imagine that there isn’t a particular level of origin of contamination inside the Scotia Sea. It’s essential to proceed finding out on this line to higher perceive the dynamics of these substances and their results on these ecosystems to information new administration insurance policies in the Antarctic continent ”, he concludes Filipa Bessa, one other of the research’s authors.
