Current GerES and ESB results and updated exposure factors in RefXP are combined for the analysis of environmental health topics. Methods GerES is a cross-sectional population study carried out repeatedly since 1985. GerES comprises human biomonitoring (HBM), indoor monitoring and interviews. On a yearly basis, the ESB collects human samples which are cryo-archived and analyzed for various pollutants. All 20-29 years old ESB participants report on their behaviors and anthropometrics. RefXP includes approx. 1,000 entries on exposure factors for the German population, e.g. body-weight, food consumption, and soil/dust ingestion. <BR>Results:<BR>GerES and RefXP data were used to estimate German childrens inhalative exposure to indoor air pollutants. For alpha-pinene the median estimate is 2.7, for xylene 1.4 ìg/(kg d). GerES interviews revealed substantial seasonal differences in ventilation behavior, indicating the need for separate exposure models for summer and winter. ESB data documents time trends in human exposures and in exposure influencing factors: Urinary mercury decreased from 0.6 in 1997 to 0.07 ìg/L in 2013. This can partly be explained by a decreasing fraction of participants with dental amalgam (1997: 83% vs. 2013: 10%). <BR>Conclusions: <BR>Combining data from GerES, ESB, and RefXP yields a more complete view on environmental exposures in the German population: Integrating HBM and exposure modelling provides comprehensive data on exposures, relevant exposure pathways, and information on the potential effect of policy measures aiming for improving environmental health.
