Urinary Naphthalene Metabolite Levels in California Schoolchildren, 2021

A pilot study collected 69 urine samples from 18 children aged 5-13 in Stockton, California, USA, in 2021. The samples were analyzed for metabolites of polycyclic aromatic hydrocarbons and volatile organic compounds, with results compared to national NHANES data. The dataset was authored by Susan Hurley and published under a CC-BY-4.0 license.

Use Cases

• Assess disparities in naphthalene exposure based on demographic data mentioned in the description
• Compare temporal trends in PAH metabolite levels using the NHANES comparison data
• Identify potential sources of elevated naphthalene exposure in specific communities
• Support policy recommendations for expanded biomonitoring of schoolchildren

Strengths

• Includes direct biomarker measurements from 69 urine samples
• Provides a comparison to national NHANES data collected 3-11 years earlier
• Focuses on a specific vulnerable demographic: 18 children, 78% Hispanic, aged 5-13

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 very small at 18.0 KB, indicating limited scope
