Urinary Naphthalene Metabolite Levels in California Schoolchildren, 2021

A 2021 pilot study collected 69 urine samples from 18 schoolchildren in Stockton, California. The data compares levels of polycyclic aromatic hydrocarbon (PAH) and volatile organic compound (VOC) metabolites to earlier national survey data. The dataset was authored by Susan Hurley and published on figshare.

Use Cases

• Analyzing disparities in naphthalene exposure based on demographic factors like age and ethnicity mentioned in the description.
• Comparing urinary metabolite levels for specific PAHs and VOCs to national reference data (NHANES).
• Identifying potential sources of elevated naphthalene exposure in specific communities.
• Monitoring temporal trends in children's exposure to common air pollutants.

Strengths

• Direct comparison to a national reference dataset (NHANES) for context.
• Specific demographic details provided: 18 children aged 5-13, 78% Hispanic.
• Clear temporal and geographic scope: samples collected in Stockton, CA, USA in 2021.

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.
