Unsupported 210Pb (Pbexc) is generated in air and is subsequently deposited on soil surface. The Pbexc can be used for sediment dating, soil erosion/sedimentation and air mass studies.In many cases, 210Pb activity determination ...

The Constant Flux and Constant Sedimentation (CF:CS) of supported/excess 210Pb model was successfully used to study sediment profiles from Antas stream, located in the region of Poços de Caldas city, Minas Gerais State, ...

Guajará Bay is an integral part of the Amazon Estuary system, and functions as the main receiver of urban and industrial wastes from the city of Belém, capital city of PA State (N Brazil). There is a lack of knowledge ...

The constant initial concentration (CIC) of unsupported/excess Pb-210 model was successfully used to assess Pb-210 data of nine sediment cores from Atibaia River basin São Paulo State Brazil The Pb-210-based apparent ...

The rivers, lakes and dam sediment analyses are able to predict the back conditions of these ecosystems and determine how the environment changed as a result of anthropogenic activities. In this way they can be used as ...

The constant initial concentration (CIC) of unsupported/excess Pb-210 model was successfully used to assess Pb-210 data of nine sediment cores from Atibaia River basin São Paulo State Brazil The Pb-210-based apparent ...

The Constant Flux: Constant Sedimentation (CF:CS) and Constant Rate of Supply (CRS) of unsupported/excess Pb-210 models have been applied to a Pb-210 data set providing of eighteen sediments profiles sampled at four riverine ...
