Mean Brodifacoum Residue Levels in Fish from Midway Atoll, 2022–2024

Midway Atoll's Sand Island provides a dataset of mean brodifacoum residue levels in systematically collected fish. The data includes method limits of detection (MLOD) and quantitation (MLOQ), with 'ND' for not detected and 'N/A' for non-applicable entries. It was authored by Carmen C. Antaky and covers the period from 2022 to 2024.

Use Cases

• Analyze mean brodifacoum residue levels across fish species to assess contamination trends on Sand Island.
• Compare detected residue values against the method limit of detection (MLOD) and method limit of quantitation (MLOQ) to evaluate measurement sensitivity.
• Identify samples marked as 'ND' (not detected) or 'N/A' (not applicable) to filter data for statistical analysis of contaminant presence.

Strengths

• Data is focused on a specific geographic location: Sand Island on Midway Atoll in the Northwestern Hawaiian Islands.
• Covers a defined time range of 2022 to 2024 for tracking recent environmental conditions.
• Includes key analytical metrics like MLOD and MLOQ for interpreting residue measurements.

Limitations

• The dataset is very small at 13.5 KB, indicating a limited number of observations or samples.
• Row and column counts are unknown, making it difficult to assess the dataset's scale and structure for analysis.
• Data entries include non-numeric codes ('ND', 'N/A') which require specific handling before quantitative analysis.
