Abstract

A stable isotope based human exposure test to study SC>2 load effects P. Krumbiegel", 0. Herbarth", M. Richter", I.

S02 is known to come from large-scale lignite combustion used in power stations there. At the same time, children of two kindergartens near the power stations who belong to a typical risk group, were tested two times a year. i. e., in March and in September. For this, a stable isotope based function test was developed and used to study actual activities of the hepatic monooxygenases: A certain amount of the stable isotope diagnostic agent [I^Njmethacetin was administered orally. Over 9 hours, the total urinary amount of ^N characterizing the sum of eliminated metha
