[Air and noise pollution caused by traffic in a small Swiss town].

In order to evaluate the extent of annoyance caused by air pollution and noise immissions, we measured the values in the small town of Uznach, which is crossed by a narrow and sloped street with a heavy traffic. The results revealed that noise immissions exceed the "alarm-value" of 70 dB(A) and that pollution of the air is situated in the range of limit values.
