Summary

Descripción general del contenido del recurso.

Feathers are useful to determine mercury (Hg) contamination. We evaluated the mercury concentration in feathers of Magellanic penguins (Spheniscus magellanicus) age 1.5. years to 25. years at Punta Tombo, Argentina before and during their molt. Mercury ranged between <1.4 and 367. ng/g. dry. weight, with three extreme high values (8996. ng/g, 3011. ng/g and 1340. ng/g) all in young adults. The median concentration was lowest for juveniles and significantly higher for adults but with high variation among older adults. Males and females had similar mercury loads. Compared with other penguin species, concentrations in Magellanic penguins were low. Mercury levels for Magellanic penguins in the Southwest Atlantic for older adults averaged 206 ± 98 ng/g, and serve as a baseline for biomonitoring and/or ecotoxicological studies.
