Paper Title
Dissolved Uranium in Surface Waters of Alambari River, São Paulo State, Brazil

Abstract
This paper describes the characterization of the natural radioelement uranium surface waters of Alambari river occurring at São José dos Campos city, São Paulo State, Brazil. The Inductively Coupled Plasma Mass Spectrometry (ICP-MS) technique was successfully applied to the analysis of 32 samples collected in two field campaigns, the first realized in late October and early November 2019 and the second in December 2020, both at previously defined and regularly distributed points along the channel drainage.The analytical results were submitted to statistical analysis taking into account several physicochemical and chemical parameters previously determined in the same water samples, which allowed identify the relevant contribution of chloride for the U-transport in the studied site.
