*Geometric mean was not calculated because the chemical was found in less than 65% of the study group.
▶CARE-LA data were weighted (a statistical method to adjust over-represented and under-represented demographic characteristics in a study sample) so that the summary results adequately reflect the population of California’s Los Angeles County. Unweighted results are available to download on the California Regional Exposure Study, Los Angeles County (CARE-LA) project page.
**LOD changed during the time that samples were analyzed for this project.
