Abstract: | The lanthanide elements, Th and U were measured in soils and agricultural crops collected in an area polluted by emissions
from a phosphate fertilizer plant. Concentrations of the above elements in the soil and crop samples were determined by instrumental
neutron activation analysis (INAA). Selected crop samples were also analyzed using radiochemical neutron activation analysis
(RNAA) based on alkaline-oxidative fusion of the irradiated samples followed by precipitation of REE oxalates. Elevated levels
of lanthanides, Th and U were found in some samples, especially in wheat chaff and parsley. |
