Since the symptoms could not be explained on the basis of the knowledge at that time, both the Federal and the State governments initiated

Die Vierspindel-Automaten System Acme,ss are quite different and depend strongly on the attendant conditions, the constituent to be measured and the quality of the available technique. In any case, the quantification of dry deposition is much more difficult and subject to errors as compared to that of wet deposition.

The pronounced dependence of the amount of precipitation on the wind direction (cf. Fig. 7.5) suggests that the wet deposition is predominantly influenced by sources

The relative contributions of the individual size fractions to the total flux vary from element to element, since the concentration distributions can be quite different. Here, the origin plays an important par

Das Einrichten von Halbautomatenc gas concentrations are subject to the influence of the current weather conditions. Such phenomena which have already been described for the particulate concentrations and the dry deposition of trace elements (Chap. 9) find an analogue above all in the case of the sulphur dioxide immission, which a
