Trace Metals and Radionuclides in Austrian Forest Ecosystems
نویسندگان
چکیده
An abundance of trace metals in the environment is a characteristic property of only a few terrestrial ecosystems. Serpentinite contains high concentrations of trace metals especially Ni and Cr that are released by weathering. Other natural sources of trace metals are volcanic eruptions and the deposition of marine aerosols. In the soil some trace metals are strongly adsorbed to the mineral matrix or fixed in stable complexes with soil organic matter, other ones are quite mobile. Trace metals show a high affinity to humic acids, iron oxides, clay minerals and carbonates in the soil.

Fungi Contaminated by Radionuclides: Critical Review of Approaches to Modeling
INTRODUCTION Data derived from sampling at areas contaminated by the Chernobyl fallout have demonstrated the organic layer of soil to be a major pool of radiocesium in forest ecosystems (Linkov and Schell, 1999, Ruhm et al., 1996). Fungi can directly bind or precipitate radionuclides; they also can indirectly affect radionuclide speciation and mobility in forest soils (Gadd, 1996). Fungi are th...
متن کاملLong-term Environmental Behaviour of Radionuclides
T his document provides an overview on the recent advances in Europe concerning the long-term environmental behaviour of radionuclides. It describes and illustrates the most significant scientific achievements gathered through three European projects, PEACE, LANDSCAPE and EPORA, which have been co-funded by the European Commission (DGXII) under the Nuclear Fission Safety Programme.

متن کاملTrace Metal Inventories and Lead Isotopic Composition Chronicle a Forest Fire’s Remobilization of Industrial Contaminants Deposited in the Angeles National Forest
The amounts of labile trace metals: [Co] (3 to 11 µg g-1), [Cu] (15 to 69 µg g-1), [Ni] (6 to 15 µg g-1), [Pb] (7 to 42 µg g-1), and [Zn] (65 to 500 µg g-1) in ash collected from the 2012 Williams Fire in Los Angeles, California attest to the role of fires in remobilizing industrial metals deposited in forests. These remobilized trace metals may be dispersed by winds, increasing human exposures...
