Brodifacoum Residue Levels in Midway Atoll Environmental Samples, 2022-2024

Mean brodifacoum residue levels in plant, soil, and water samples collected systematically on Sand Island, Midway Atoll from 2022 to 2024. The dataset includes method detection limits (MLOD) and quantitation limits (MLOQ), with 'ND' for not detected and 'N/A' for non-applicable results. It was authored by Carmen C. Antaky and is available under a CC BY 4.0 license.

Use Cases

• Compare mean brodifacoum residue levels across plant, soil, and water sample types to assess environmental distribution.
• Analyze detection frequency using the 'ND' (not detected) flag against the MLOD and MLOQ values to evaluate contamination prevalence.
• Map the temporal trend of residue levels from 2022 to 2024 for a specific environmental medium (e.g., soil).

Strengths

• Data collection was systematic across three environmental matrices (plant, soil, water) on Sand Island.
• Includes explicit method quality metrics: MLOD (method limit of detection) and MLOQ (method limit of quantitation).
• Covers a defined multi-year time range from 2022 to 2024.

Limitations

• The dataset is very small at 9.5 KB, indicating a limited number of samples or observations.
• Row and column counts are unknown, preventing assessment of statistical power or feature scope.
• Data granularity is limited to mean residue levels, lacking raw individual sample measurements for variance analysis.
