    Environmental assessment of arsenic released from potential pollution sources (1984)

    Notes: Abstract An assessment study of the environmental pathways of arsenic released from a coal-fired power plant (CFPP) or introduced into soil as a contaminant by phosphatic fertilizers has been carried out using a time-dependent forecasting model. The long-term predictions indicate that arsenic can be taken up by plants and that it can migrate into the groundwater system through soil layers. However, arsenic exhibits such a high degree of mobility that its retention and accumulation in biota should remain low. This fact may explain the relatively low concentrations of arsenic in environmental media as well as in groundwater systems.

    Use of cell cultures, nuclear and radioanalytical techniques for metallotoxicological studies at the JRC-Ispra (1993)
    Springer
    Cytotechnology 11 (1993), S. S24 
    Details
    ISSN: 1573-0778

    Topics: Biology , Medicine , Process Engineering, Biotechnology, Nutrition Technology
    Notes: Abstract This paper reviews the JRC-Ispra research activity on toxicological studies related to the environmental and occupational exposure of trace metals, as carried out by a combination of cell culture methodologies with nuclear and radioanalytical techniques. Applications concern the setting of uptake-effect relationships and the study of the mechanisms of toxicity of specific metals (Al, As, Cd, Co, Cr, Mo, Se, V), as well as the establishment of ranking of metal toxicity by carrying out systematic studies (screening tests).

    Application of radiotracers with high specific radioactivity to metallotoxicological studies (1992)
    Springer
    Journal of radioanalytical and nuclear chemistry 160 (1992), S. 493-503

    ISSN: 1588-2780

    Notes: Abstract The use of radiotracers with high specific activity in research on health impact of trace metals overcomes many of the analytical difficulties associated with experimentation carried out at metal levels which are typical of the polluted environment. It allows one to detect and measure ultratrace amounts of metals in biological samples and to follow them into different biochemical compartments, such as subcellular fractions and molecular components. This work shows typical examples of metallotoxicological studies carried out at the JRC-Ispra using radioisotopes with high specific radiactivity produced in the nuclear reactor and in the cyclotron. Applications refer to the use of45Ti,48V,64Cu,95Nb and106mAg in in-vivo and in-vitro studies related to environmental and occupational toxicology research on trace metals.

    Preparation of high specific activity radiotracers for radioanalytical studies (1992)
    Springer
    Journal of radioanalytical and nuclear chemistry 160 (1992), S. 549-561

    Notes: Abstract High specific activity radiotracers are very suitable for studies related to the toxicological impact of trace elements onto human health. In order to investigate the metabolic behaviour of Low Level Exposure (LLE) to trace elements, it is necessary to carry out in-vitro and in-vivo experiments with tracers whose concentration is of the same order of magnitude as the present environmental exposure values (ng-μg/kg day). Preparations, separations and purifications of some No Carrier Added (NCA) radiotracers (48V,95m,96Tc,195m,g,197m,gHg,199Au,202Tl) produced by either cyclotron or nuclear reactor irradiation, are presented and discussed. This work reviews the more recent advances in this field carried out by our groups.
