A preliminary study of trace metals and porphyrins in excreta of Gentoo penguins (Pygoscelis papua) at two locations of the Antarctic Peninsula

Abstract: RESUMENAunque las concentraciones de la mayoría de los elementos químicos en la Antártica son bajas en comparación con otras áreas del planeta, éstas se han ido incrementando con el tiempo debido al gran crecimiento de la población y desarrollo industrial de los países del Hemisferio Sur, lo cual podría estar afectando a especies vulnerables como los pingüinos. Se determinaron las concentraciones (peso seco) de arsénico (As), cadmio (Cd), mercurio (Hg) y plomo (Pb) y porfirinas (copro-, uro-y proto-) en heces … Show more

“…The Gentoo penguin is a seabird at the top of the food chain of Antarctic marine ecosystems, thus playing an important role in the ecology of the coastal zones of Antarctica (Celis et al 2012). There are some important colonies of this species that inhabit the Antarctic Peninsula.…”

“…Moreover, seabirds are significant biovectors of contaminants via excreta from the ocean to the land (Michelutti et al 2009). For that reason, excreta and feathers have been used as appropriate bioindicators to study pollution in marine ecosystems with a minimum of human intervention (Sun and Xie 2001;Ancora et al 2002;Yin et al 2008;Jerez et al 2011;Celis et al 2012).…”

“…[1][2][3] Devido ao isolamento, os bens naturais desse continente demoraram um tempo para ser explorados. Foi a partir de 1900 que as Ilhas Antárticas começaram a ser exploradas principalmente para a pesca de baleias e outros animais marinhos, o que provocou o transporte e introdução de espécies animais e vegetais exóticas, acarretando um desequilíbrio ambiental.…”

“…[12][13][14] A determinação dos elementos traço nestas matrizes ambientais contribui na avaliação da disponibilidade desses contaminantes para os seres vivos que habitam o local e no controle dos impactos das atividades antrópicas. 2,3,15 Diante disso faz-se necessário o uso de técnicas analíticas que sejam adequadas para a avaliação e monitoramento dos teores dos elementos traço.…”

“…Ecosystems with little human presence, such as Antarctica, are of great importance to study the health status of the biota that lives there, being of great concern among scientists (Ballschmiter et al 2002, Corsolini et al 2003, Barbosa et al 2007. Within this biota, marine birds, such as penguins, are excellent bioindicator organisms of the health of Antarctic ecosystems, since they can clearly express the biological effects of man-made chemical pollutants (Boersma 2008, Celis et al 2012.…”
