Untersuchungen über die Eignung verschiedener Probenarten als Indicatoren für Schwermetallbelastung
Indicators for long-and short-term environmental pollution in different regions with different environmental influences (agriculture, industry, etc.) become world-wide more and more of interest. The main question in this connection is how a substance can give evidence for environmental research.
Different materials like human placenta, animals (or some organs of these), plants and soils have been discussed in the last few years for use as indicator substances. The use of bioindicators will be discussed in this paper by means of some examples from the research work of our laboratory. About twenty elements, including nearly all the heavy metals like As, Hg, Cd, Pb, etc. and essential trace elements like Cu, Fe, Mn, Zn, etc. have been investigated in these experiments. Main emphasis is laid on the differentiation between “normal” biological scattering of data and the environmental influence.
