    Inorganic chemical investigations in the Forest Biosphere Reserve near Kalinin, USSR (1991)
    Springer
    Plant ecology 95 (1991), S. 127-135 
    Details
    ISSN: 1573-5052
    Keywords: Bioindication ; Heavy metals ; Plant analysis ; Chemical elements ; Peat profiles
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Abstract To get a first impression of the degree of pollution in the Forest Biosphere Reserve 350 km northwest of Moscow, samples of Polytrichum commune and peat profiles were measured by ICP/MS after decomposition by high-pressure ashing. Comparing the results with data found in similar systems in Central Europe the Forest Biosphere Reserve can be described than ‘medium-polluted’ by heavy metals. Pb shows lower values as in comparable systems in Germany, due to the fact of lower traffic density in Sowjetunion. The status of the nutritional elements Ca, Mg and K is in the same order of magnitude as found in German forest ecosystems.

    Presence and significance of naturally occurring chemical elements of the periodic system in the plant organism and consequences for future investigations on inorganic environmental chemistry in ecosystems (1992)
    Springer
    Plant ecology 103 (1992), S. 1-30 
    Details
    ISSN: 1573-5052
    Keywords: Element Concentration Cadasters ; IUBS project ; Multielement analysis ; Element toxicity ; Occurrence ; Essentiality ; Accumulation ; Consumption
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Abstract After acceptance of the “Element Concentration Cadasters in Ecosystems” (ECCE) programme as an international project sponsored by the International Union of Biological Sciences (IUBS) at the 24th General Assembly of IUBS in Amsterdam in Sept 1991, the present status of “Biological Trace Element Research” (BTER) is presented here from the biological point of view. Especially information on occurrence, essentially, toxicity and uptake form of all 88 naturally occurring chemical elements is presented. In addition an estimated annual production of each element in the year 2000 and examples of their technical application is given. A scientific proposal for further research work on a local, regional and global scale has been discussed.
