WITHIN-PERSON REPRODUCIBILITY OF RED BLOOD CELL MERCURY OVER A 10–15 YEAR PERIOD AMONG WOMEN IN THE NURSES’ HEALTH STUDY II

摘要

BackgroundMost epidemiologic studies of methylmercury (MeHg) health effects rely on a single measurement of a MeHg biomarker to assess long-term exposures. Long-term reproducibility data are, therefore, needed to assess the reliability of a single measure to reflect long-term exposures. In this study we assessed within-person reproducibility of red blood cell (RBC) mercury (Hg), a marker of methyl-mercury, over 10–15-years in a sample of 57 women.
