Northern Leopard Frog Larval Development Under PFAS Exposure in Outdoor Mesocosms

A 30-day experimental dataset from Purdue University West Lafayette assesses the impact of perfluoroalkyl substances (PFAS) on amphibian development under semi-realistic conditions. Northern leopard frog larvae were reared in outdoor mesocosms with sediment spiked to low, medium, and high levels of PFOS or PFOA. The data likely contains measurements of developmental stages and chemical concentrations.

Use Cases

• Modeling developmental delays in amphibians based on PFAS concentration levels mentioned in the description
• Comparing toxicity effects between PFOS and PFOA compounds under semi-realistic conditions
• Assessing the relationship between sediment PFAS levels and aquatic concentrations for ecological risk assessment

Strengths

• Data was collected under semi-realistic outdoor mesocosm conditions, which the description suggests is more representative of environmental exposures than laboratory tests
• Developmental effects were observed at low PFOS concentrations in water (0.06 ppb), as stated in the description

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
