The Biomonitoring Exposures Study (BEST) Expanded is a continued joint effort between Biomonitoring California and the Kaiser Permanente Northern California (KPNC) Division of Research.  Expanded BEST is measuring environmental chemical exposures in 341 adult KPNC members living in California’s Central Valley.  Together with Pilot BEST, this is the first Biomonitoring California study to collect samples from participants randomly selected across gender, age, race/ethnicity, and location.  Expanded BEST places a special emphasis on sampling of Hispanics and Asian/Pacific Islanders.  English and Spanish questionnaires, medical information, and blood and urine samples were collected in 2013.
