Ean. Fernandes et al., TRACE-ELEMENTS DISTRIBUTION IN THE AMAZON FLOODPLAIN SOILS, Journal of radioanalytical and nuclear chemistry, 179(2), 1994, pp. 251-258
Neutron activation analysis was performed on aluvial soil samples from
several sites on the floodplains of the Amazon River and its major tr
ibutaries for trace elements determination. The spatial and temPoral v
ariations of chemical composition of floodland sediments in the Amazon
basin are discussed. No significant difference was found in trace ele
mental distribution in the floodland soils along the Amazon main chann
el. even after the source material has been progressively diluted with
that from lowland draining tributaries. It was also seen that the ave
rage chemical composition of floodplain soils compares well with that
of the suspended sediments.
