Urinary PAH and VOC Metabolite Levels in California Schoolchildren, 2021

A 2021 pilot study in Stockton, California, USA, collected 69 urine samples from 18 children aged 5-13. The data, authored by Susan Hurley, compares metabolite levels of polycyclic aromatic hydrocarbons and volatile organic compounds to national reference data from the National Health and Nutrition Examination Survey.

Use Cases

• Assess disparities in naphthalene exposure based on demographic factors mentioned in the description
• Compare urinary metabolite levels for specific PAHs and VOCs to national reference data
• Identify potential exposure sources for elevated naphthalene levels in a specific community
• Analyze temporal trends in children's chemical exposure by comparing to older NHANES data

Strengths

• Includes a direct comparison to a national reference dataset (NHANES)
• Provides specific demographic context: 18 children, predominantly Hispanic (78%), aged 5-13
• Focuses on a vulnerable population in a community described as heavily burdened by air pollution

Limitations

• Row count is unknown, which may limit suitability assessment
• Column-level documentation is absent; field semantics must be inferred after download
• Small sample size (69 samples from 18 children) limits generalizability
