Resumo
The Cananéia-Iguape system is a complex of lagoon and estuarine channels located in the south of state of São Paulo. This
system received the waters of Ribeira de Iguape River, after the construction of a channel in 1852, which changed its original
characteristic. This study evaluated the uranium and thorium concentrations in superficial bottom sediments samples from
this system by spectrophotometric determination. The mean uranium concentration found was 2.9 mg kg−1 and 6.6 mg kg−1
for thorium. Geo-accumulation index classified the sediments as “unpolluted to moderately polluted”. Statistical analysis
showed that uranium and thorium presented a non-homogeneous behavior along the system.
