PFAS Exposure: Suspect Screening Data from LC-HRMS Reanalysis

Lapo Renai provides supplementary data tables supporting a wide-scope PFAS suspect screening and retrospective reanalysis of LC-HRMS exposomics datasets. The repository contains CSV files documenting the suspect list construction, filtering steps, and identification of homologous series across two datasets. The data was last updated on May 7, 2026.

Use Cases

• Validating suspect screening workflows based on the provided complete PFAS suspect list.
• Identifying homologous series of contaminants based on CF₂-normalized KMD patterns documented in the common_homolog_series.csv file.
• Anchoring retention behavior in analytical models based on the provided lists of PFAS internal standards.
• Inspecting feature detection steps based on the documented successive filtering criteria applied to the datasets.

Strengths

• Includes a complete suspect list with structural identifiers and physicochemical descriptors, forming a basis for analysis.
• Documents successive filtering steps applied to two distinct datasets, providing transparency.
• Data is provided in CSV format to facilitate reuse and downstream analysis.
• The dataset is openly licensed under CC-BY-4.0.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The total size is 4.9 MB, indicating a relatively small dataset.
