Trends in urinary metabolites of polycyclic aromatic hydrocarbons (PAHs) in the non-smoking U.S. population, NHANES 2001-2014.

ABSTRACT:

Background

Recent studies indicate airborne PAH levels have decreased in the U.S., but it is unclear if this has resulted in PAH exposure changes in the U.S.

Population

Objective

Examine temporal trends in urinary metabolites of Naphthalene, Fluorene, Phenanthrene, and Pyrene in U.S. non-smokers, 6+ years old.

Methods

We used biomonitoring data from the National Health and Nutrition Examination Survey (NHANES) program, 2001-2014, (N = 11,053) using survey weighted linear regression. Models were adjusted for age, sex, race/ethnicity, creatinine, BMI, income, diet, and seasonality. Stratified models evaluated the effect of age, sex, and race/ethnicity on trends.

Results

Between 2001 and 2014, Naphthalene exposure increased 36% (p < 0.01); Pyrene exposure
