A team of researchers from the University of Concepción (UdeC), in collaboration with specialists from Harvard University and Purdue University, conducted an innovative study on metal pollution in Humboldt penguins.
The study detected the presence of metals and metalloids in the bones and claws of the Humboldt penguin, a vulnerable species on the coasts of northern Chile.
Context and Methodology
The Humboldt penguin is a seabird that plays a crucial ecological role in the coastal ecosystems of northern Chile. Pollution from heavy metals, a result of the massive development of mining activities, could be negatively affecting these populations.
The study, published in the Austral Journal of Veterinary Sciences, used the technique of X-ray Fluorescence Spectrometry to carry out a non-destructive and more sustainable analysis.
Findings and Collaboration
The results showed levels of metals that could be a consequence of acute or chronic exposure while the penguins were alive. This data can serve as a basis for future studies that help protect this vulnerable species.
Collaboration with experts from prestigious universities and the use of state-of-the-art analytical equipment were fundamental for the development of this study.
Impact and Population of Humboldt Penguins
Pollution from heavy metals has significantly affected Humboldt penguin colonies, whose population has decreased notably compared to previous censuses.
The species resides along the Pacific coast of South America, from La Foca Island in Peru to Metalqui Island in Chile.
