Measurements of organochlorine pesticides and polybrominated diphenyl ethers in species from the Adelie penguin food web near McMurdo Station. Data includes concentration levels for cod, krill, and penguin eggs, with specific readings such as ΣPBDE6 at 311 ng/g in cod. The dataset was produced by the organization SCIOPS and last updated in January 1996.
Use Cases
- Analyze ΣPBDE6 concentration in cod to assess pollution hotspots near McMurdo Station.
- Compare organochlorine pesticide levels between species like krill, rock cod, and penguin eggs.
- Model long-range transport of volatile pollutant congeners across the Antarctic food web.
- Investigate biologically mediated export of contaminants from polluted to pristine areas using cod location data.
Strengths
- Provides specific concentration measurements, such as 311 ng/g ΣPBDE6 in cod.
- Includes comparative data from a 2006 study with concentration ranges of 3.06 to 5.81 µg/kg.
Limitations
- Dataset is temporally stale, with a last update in 1996.
- Sample size and row count are unknown, limiting statistical robustness.
- Geographic coverage is limited to specific Antarctic sites like Cinder Cones and Terra Nova Bay.
