Brodifacoum Residue Levels in Midway Atoll Wildlife Carcasses

Mean brodifacoum residue levels measured in carcasses from shorebirds, seabirds, ducks, egrets, passerines, fish, and invertebrates collected on Midway Atoll. Livers were analyzed for all avian samples, with data indicating method limits of detection (MLOD) and quantitation (MLOQ). The dataset was authored by Carmen C. Antaky and is available under a CC BY 4.0 license.

Use Cases

• Compare mean brodifacoum residue levels across taxonomic groups like shorebirds, seabirds, and fish to assess bioaccumulation patterns.
• Analyze the frequency of 'ND' (not detected) entries versus quantified residues to understand exposure prevalence in the ecosystem.
• Use MLOD and MLOQ values to evaluate the sensitivity and reliability of the toxicological analysis for different sample types.
• Investigate residue data from avian liver samples specifically to study the compound's metabolic impact on birds.

Strengths

• Data covers multiple wildlife taxa including birds, fish, and invertebrates, providing a broad ecological snapshot.
• Includes critical methodological metadata such as MLOD and MLOQ for interpreting analytical results.
• Geographic scope is precisely defined to Midway Atoll in the Northwestern Hawaiian Islands.

Limitations

• The dataset is very small at 13.5 KB, indicating limited sample size and analytical scope.
• Sample data and specific row/column counts are unavailable, hindering assessment of data structure and volume.
• Relies on mean residue levels, which may obscure individual sample variance and outlier data points.
