摘要：

Airborne platinum concentrations sampled over 4 h in local buses in Munich during regular rides were analyzed by adsorptive stripping voltammetry. The detection limit was 0.5 pg/m(3), related to an air-sampling of 5 m(3). In 96 samples from 1993 and 1994 we found a mean concentration of 7.3 pg/m(3) (S.D. 6.5). The route with highest traffic showed 33.0 pg/m(3) compared to 3.0 pg/m(3) at a suburban bus route.
