Brodifacoum Residue Levels in Soil, Water, and Wildlife at Midway Atoll

Mean brodifacoum residue levels in soil, water, reptile, and contingency samples from Sand Island, Midway Atoll. The dataset, authored by Carmen C. Antaky, covers environmental monitoring from 2022 to 2024 and includes measurements relative to method detection limits (MLOD, MLOQ).

Use Cases

• Analyze brodifacoum residue levels across soil, water, and reptile sample types to assess environmental contamination pathways.
• Compare detected residue concentrations against method limits of detection (MLOD) and quantitation (MLOQ) to evaluate measurement reliability.
• Study the spatial and temporal distribution of brodifacoum contamination in the Northwestern Hawaiian Islands ecosystem from 2022-2024.

Strengths

• Data collection is temporally bounded, covering a defined period from 2022 to 2024.
• Focuses on a specific geographic location: Sand Island, Midway Atoll, Northwestern Hawaiian Islands.
• Includes multiple environmental matrices: soil, water, reptile, and contingency samples for a multi-media assessment.
• Data is openly shared under a CC BY 4.0 license, facilitating reuse.

Limitations

• The dataset is very small at 9.5 KB, indicating limited scope and likely a low number of individual measurements or samples.
• Column structure and sample data are unavailable, preventing assessment of data granularity, feature count, or specific analytical variables.
• Data entries include 'N/A' and 'ND' (not detected), which may require careful handling for quantitative analysis.
