PFAS Concentrations in Hongyingzi Sorghum Soil, 8 Sample Sites

248 ± 106 ng/kg average concentration of seven polyfluoroalkyl substances (PFASs) in tilled soil from the Hongyingzi sorghum cultivation base in China. The data, published by Yin Qin in 2026, includes measurements from eight sample sites, with concentrations ranging from 87.8 to 446 ng/kg. It provides a first-time assessment of PFAS contamination in this agricultural area.

Use Cases

• Model spatial distribution of PFAS contamination based on the eight sample sites and ordinary kriging method mentioned.
• Assess ecological and human health risks based on the provided risk evaluation results for PFOA and other PFASs.
• Analyze source contributions of PFAS pollution using the principal component analysis results linking pollutants to rural living, agricultural, and industrial activities.
• Track substitution trends from legacy to emerging PFASs based on the reported 41.8% contribution from emerging compounds.

Strengths

• Includes specific concentration measurements for seven PFASs, with an average of 248 ± 106 ng/kg.
• Provides source attribution analysis linking specific PFASs to rural living, agricultural, and industrial activities.
• Contains both ecological and human health risk assessments for the detected contaminants.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is a 1.3 MB PDF, which may require extraction of underlying tabular data.
