Environmental, Toxicological and Biomedical Research on Trace Metals: Radiochemical Separations for Neutron Activation Analysis

TWENTY-TWO RADIOCHEMICAL SEPARATION PROCEDURES FOR NEUTRON ACTIVATION ANALYSIS (NAA) OF ENVIRONMENTAL AND BIOLOGICAL SAMPLES ARE PRESENTED. THEY ARE CURRENTLY APPLIED IN THE CONTEXT OF TRACE METAL RESEARCH RE- LATED TO THE PROTECTION OF THE ENVIRONMENT AND HUMAN HEALTH. THE RADIO- CHEMICAL PROCEDURES ARE REFERRED TO THE SEPARATIONS OF THE ELEMENTS INTO GROUPS WHICH ALLOW THE DETERMINATION OF AT LEAST 50 ELEMENTS IN EACH SAMPLE OR TO SPECIFIC SEPARATIONS FOR SINGLE ELEMENTS. THE EXPE- RIENCE GAINED IN THE APPLICATION OF THESE RADIOCHEMICAL SEPARATIONS OVER MORE THAN TEN YEARS ALLOWS US TO CONSIDER THEM AS RELIABLE FOR SENSITIVE DETERMINATIONS OF TRACE METALS IN ENVIRONMENTAL AND BIOLOGI- CAL SAMPLES.NA-NOT AVAILABL

Trace and nutrient element transfer from sewage sludge-amended soil to crop - A study on Brassica oleracea.

Brassica oleracea was used for plant availability studies and the material will also be available for quality control purposes. The cabbage, grown on sludge-amended soil, was harvested and processed to a homogeneous powder. The results of a preliminary test on homogeneity and a broad spectrum of element concentrations determined are reported. The soil around the plants was also collected and examined. Estimates of uptake coefficients Ccrop/Csoil are given
