    Notes: Abstract Thirty two cores were collected from Lake Geneva sediments along one longitudinal and eight transverse profiles. Rates of sedimentation determined by137Cs vary from 0.01 to 1.86 g cm−2 y−1. The average deposition rates in coastal and slope areas amounts to 0.37 g cm−2 y−1 in the Upper Lake (Grand Lac) and 0.12 g cm−2 y−1 in the Lower Lake (Petit Lac). In the deep basins, average rates of 0.13 and 0.05 g cm−2 y−1 were found for the Grand Lac and Petit Lac, respectively. The estimated mass of sediment deposited yearly outside of the principal deltas and turbidity current depositional areas is about 1.0 million tons (about 13% of the estimated total river load). One turbidite is clearly identified in the deepest, central lake area. There is little variation of surface sediment texture (mean grain size about 8–9µm) with the exception of delta areas. Since the beginning of the twentieth century, both carbonate and organic matter have increased as a result of lake eutrophication.

    Notes: Abstract Sedimentation rates were determined by210Pb in three sediment cores from the main basin of Lake Constance. Rates vary from 0.094 to 0.133 g cm−2y−1, in agreement with previous determinations. A constant radionuclide flux (CR) model reveals long-term, quasi-synchronous fluctuations of sedimentation rate on the basin-wide scale. On average, the rate of sedimentation remains much the same from the beginning of this century indicating little effect of human activity in the watershed on fine-silt sediment supply. The anthropogenic fluxes of Zn, Pb, and Cd in the three cores are compared and the application of210Pb as a heavy metal tracer in Lake Constance is examined. It seems to be a very good tracer for Pb, moderately good for Zn and Cu, and not useful for Cd.

    Notes: The integrability of R2-gravity with torsion in two dimensions is traced to an ultralocal dynamical symmetry of constraints and momenta in Hamiltonian phase space. It may be interpreted as a quadratically deformed iso(2,1)-algebra with the deformation consisting of the Casimir operators of the undeformed algebra. The locally conserved quantity encountered in the explicit solution is identified as an element of the center of this algebra. Specific contractions of the algebra are related to specific limits of the explicit solutions of this model.

    Partition of metals in the Vistula River and in effluents from sewage treatment plants in the region of Cracow (Poland) (2000)

    Notes: The Vistula River suffers from heavy pollution with multiple origins. In the upper reaches, metallic and chlorine pollution originates from the mining and industrial region of Upper Silesia. Downstream from Upper Silesia, urban and industrial sewage adds more metallic and organic contaminants from the large urban agglomeration of Cracow. Although the river status is monitored routinely, little is known about the partition of metals between particulate and dissolved forms. This study focuses on metal partitioning and on the impact of the two main wastewater treatment plants at Cracow on metal concentrations in the Vistula River. The Cd, Co, Cu, Mn, Pb and Zn content was measured in both dissolved and particulate fractions. High metal concentrations in the Vistula River persist, although current levels seem to be lower than those in the past. Metal concentrations in the Vistula River and effluents from the sewage treatment plants at Cracow are similar, indicating a relatively minor contribution from the treated sewage. However, untreated sewage may be a significant source of contaminants. Despite high anthropogenic metal concentrations, the metal partitioning coefficients (Kd) in the Vistula are similar to these found in unpolluted rivers. Within a narrow pH range, Kd values depend on the metal affinity to particles, but there is no evidence of dependence on particle or chloride concentrations. An important fraction of the toxic metals Pb and Cd is associated with particles, which may decrease their immediate availability to the biota of the river.

    Forms of particulate phosphorus in suspension and in bottom sediment in the Danube Delta (2000)

    Notes: In the summer of 1995, samples of suspended solids and bottom sediments were collected from the lower course of the Danube, downstream from potential pollution sources such as tributaries draining industrialised and densely populated watersheds (the Jiu, Olt, Arges and Ialomita rivers) or big cities on the border of the river (Tulcea, Galati, Braila), and from the Danube Delta. Chemical and toxicological analyses were carried out on these samples. In the present paper, the results of the measurements of the forms of particulate phosphorus are discussed. Phosphorus occurring in the bottom sediments and the suspended solids has various origins and chemical forms. These forms may be operationally defined as: organic phosphorus (OP), apatite inorganic phosphorus (AP) and non-apatite inorganic phosphorus (NAIP). The AP shows low variability, ranging from 350 to 400 p.p.m. for suspended solids and from 425 to 500 p.p.m. for bottom sediments. This is essentially due to the detrital origin of this form. These values are typical for freshwater sediments in European rivers. The NAIP, which originates both from natural sources and from human pollution, shows a high variability. This indicates that the nutrient pollution is derived from both point and non-point sources in the watershed. The NAIP concentrations of 800 p.p.m. (Vadul Oii) and 850 p.p.m. (Oltenita) are very high (fourfold the average for European rivers), indicating that strong anthropogenic sources of phosphorus are present in the lower Danube watershed. As the NAIP is potentially bioavailable, its high concentration may contribute to eutrophication in the lower Danube and the Danube Delta.

    Zur Chronologie anthropogener Schwermetalle in den Sedimenten des Attersees (Österreich) (1983)

    Description / Table of Contents: Summary The investigation of the heavy metal concentrations of a sedimentary core from the northern part of the Attersee (Austria) revealed a bipartition of the core: a lower part (below 20 cm depth within the sediment) with generally low metal concentrations and an upper (above 20 cm depth) section, in which Cd, Zn and Pb begin to rise until a 5.6-fold (Cd), 3.1-fold (Zn) and 1.9-fold (Pb) increase is attained in the uppermost 6-4 cm layers within the sediment.210Pb and137Cs dating designate 1870–1880 as the initial stage of heavy metal pollution originating from anthropogenic sources and 1960–65 as the stage of maximum enrichment. The highest metal concentrations are in the same range as concentrations described from sediments from 7 lakes in Upper Bavaria with a similar setting (recreational areas with little or no industry). Domestic sewage and rural runoff in connection with the immission of atmospheric dust enriched in heavy metals which result mainly from coal combustion are believed to be the major metal sources. The overall low P-concentrations in the lake sediments do not vary with depth; they indicate that present oligotrophic conditions of the lake have persisted for centuries.
    Notes: Zusammenfassung Die Untersuchung eines Sedimentkerns aus dem nördlichen Teil des Attersees (Österreich) zeigt, daß die Schwermetalle Cd, Zn und Pb ab einer Sedimenttiefe von 20 cm (Sediment-Alter 1870–1880) nach oben hin±kontineuierlich ansteigen und ihre Maximalkonzentration in einer Sedimenttiefe von 6-4 cm (1960–1965) erreichen. Im Vergleich zu den unterhalb von 20 cm abgelagerten Sedimenten (die Schwermetallgehalte entsprechen dem “präzivilisatorischen Background”) sind die Schwermetallkonzentrationen in den obersten 5 cm des Kerns 5,6fach (Cd), 3,1fach (Zn) und 1,9fach (Pb) höher als Folge des Schwermetalleintrags aus häuslichen und ländlichen Abwässern sowie aus dem Eintrag von stark schwermetall-belastetem Flugstaub, der vor allem aus der Verbrennung von Steinkohle stammt. Die in den obersten Lagen des Attersee-Kernes gemessenen Konzentrationen an Cd, Zn und Pb liegen ähnlich hoch wie in Oberflächen-Sedimenten mehrerer anderer Seen Oberbayerns in Gebieten, deren Struktur mit dem Atterseegebiet vergleichbar ist. Der (insgesamt niedrige) Phosphatgehalt der Sedimente zeigt keine Abhängigkeit von der Tiefe und bestätigt den auch heute noch andauernden oligotrophen Zustand des Gewässers.

    Notes: Environmental education at technical schools and at universities has distinctive features, the profiles of which are tailored according to the teaching models of engineers and academics respectively. In this paper we suggest that the exchange of teachers and teaching methods between polytechnics and universities can be profitable for both parties. For engineers it should bring a broader perspective and more global understanding of environmental systems, while for university graduates it should help them to understand better the practical problems and limits of technical solutions. The forms of exchange and their potential benefits are still not explored sufficiently. Examples of some relatively modest forms of collaboration in environmental education between the Polytechnic of Lausanne and the University of Geneva are given to show that more vigorous exchange would facilitate mutual understanding of graduates in their future environmental careers. Better mutual understanding between engineers and natural scientists clearly will increase the societal relevance of environmental education and increase the efficiency of interdisciplinary teams.
