Footnote
●Expanded BEST data from 218 participants was weighted, a statistical method to adjust over-represented and under-represented samples, so that the summary results adequately reflect the population of California’s Central Valley. Unweighted results are available to download on the Biomonitoring Exposures Study (BEST) – 2. Expanded project page.
