Health-relevant exposures to environmental pollutants, fungi, bacteria, noise, and air pollution have to be identified at an early stage. At the same time, impacts on health and their potential environmental causes need to be investigated and documented. The German Environmental Survey for Children and Adolescents 2014-2017 (GerES V) is the environmental module of KiGGS Wave 2 of the Robert Koch Institute and takes a deeper look at the sections living conditions and health status of the KiGGS study. GerES V collects up-to-date information on the exposure of children and adolescents in Germany aged 3 to 17 to chemicals and investigates chemical and physical environmental pollutants in their living environments. The survey contributes to identifying environmental hazards and measures that effectively reduce or prevent such hazards in order to protect and promote the health of the young generation.
