Instrumentierung in der Erfassung von Umweltsproblemen

Abstract

Analytical and physical chemists have made significant contributions in the field of monitoring water and air pollutants where very specialized and reliable instrumentation is required. Usually, as is shown on some examples, standard analytical methods are first developed into apparatus for series measurements. Most methods can, nowadays, be partly or fully automated and can be operated by unskilled personnel. The continuous large scale monitoring of air and water quality requires an integrated computerized surveillance system depending on the measurement of one or a few selected tracer pollutants. The difficulties of sampling and of detecting one particular pollutant at low concentration in the presence of a great number of other substances is pointed out. Internationalization of standards and of efforts to control emissions is particularly important.
