Global PFAS Burden and Estrogenic Risk in Cetaceans, 96 Substances

96 per- and polyfluoroalkyl substances (PFAS) assigned to 17 classes were discovered in cetaceans from the East China Sea, including 6 classes reported for the first time. The dataset, created by Kai Huang and last updated in May 2026, integrates global data to analyze drivers of PFAS burden and associated estrogenic risks. It reveals that 82.6% of studied cetacean populations were under potential estrogenic risk.

Use Cases

• Modeling PFAS accumulation drivers based on feeding ecology and habitat type mentioned in the description.
• Assessing estrogenic risk to cetacean populations based on exposure data and predicted activities.
• Identifying geographic hotspots of high risk in coastal regions of Europe, North America, and East Asia.
• Studying the transformation and contribution of fluorotelomer precursors to PFAS accumulation.

Strengths

• Identifies 96 specific PFAS across 17 classes, providing a detailed chemical profile.
• Integrates global data to analyze key determinants like feeding ecology and habitat.
• Reports 6 classes of fluorotelomer sulfates in cetaceans for the first time.
• Quantifies risk, stating 82.6% of studied populations face potential estrogenic effects.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is small (139.0 KB), indicating a limited scope of raw data.
