[Clinical research].

Distinct differences were determined during the clinical examinations of the ten-year-old child population in the polluted area Rhine/Main (Wiesbaden/Frankfurt) and the control areas Freiburg and Starnberg. In the group with long-term exposure enlarged tonsils with a rough surface, enlarged lymphatic nodes in throat and mandible were frequently found. When determining body height and weight, no distinct differences between the individual areas under examination could be proved.
