Levels of metals and toxicity in sediments from a Ramsar site influenced by former mining activities
(Elsevier B.V., 2019-04-30)
This study aimed to evaluate the sediment quality in a Ramsar site located in the Southeast Brazil, by using several lines of evidence (LOEs). Chemical and sedimentological analyses, ecotoxicological tests, and whole ...
Source of polynuclear aromatic hydrocarbons found in sediment in a region of expanding sugarcane cultivation of São Paulo State, Brazil
(2016-05-01)
Purpose: Polycyclic aromatic hydrocarbons (PAHs) are unintentional products that are classified as persistent toxic substances. The goal of the present study was to generate data on the presence of 15 priority PAHs that ...
Sediment transport dynamics in a glacierized Andean basin: lessons from the Estero Morales, Chile
(2022)
Suspended and bedload transport dynamics on rivers draining glacierized basins depend on complex processes of runoff generation along with the degree of sediment connectivity and coupling at the basin scale. This thesis ...
Zircon fission track and U-Pb dating methods applied to São Paulo and Taubaté Basins located in the southeast Brazil
(2013-03-01)
Zircon samples from the Cenozoic São Paulo and Taubaté Basins and Mantiqueira Mountain Range (southeast Brazil) were concomitantly dated by zircon Fission Track Method (FTM) and in situ U-Pb dating method. While FTM ...

The Effects of Sediment Classification Pattern on a Water Column Organism, Ceriodaphnia dubia
(2018-06-01)
The sediment compartment stands out because it functions as both a temporary sink of pollutants and a potential source of these elements that may become available to the water column.This study aimed to correlate the ...
Development of a fast and inexpensive method for detecting the main sediment sources in a river basin
(Elsevier Science, 2018-11)
The sediments are a key link to understand the dynamics of a water basin, since they are the main transport and retention agent of nutrients and contaminants. Therefore, a method to identify the main sediment sources and ...
Distribution and geochemical partitioning of heavy metals in sediments of the Bahía Blanca estuary, Argentina
(Coastal Education & Research Foundation, 2005-12)
A long-term study programme has evaluated heavy metals in the Bahı ́a Blanca estuary, considering occurrence, concentration and distribution in the estuarine sediments, as well as their corresponding geochemical partitioning ...
Modelling deltaic progradation constrained by a moving sediment source
(Int Assoc Hydraulic Research, 2013-06)
A physically-based moving boundary model of deltaic progradation is developed. Surface of the axially symmetric, inner delta is free to grow or shrink in time, while the sediment source is allowed to migrate along the ...
Vegetation and topographic controls on sediment deposition and storage on gully beds in a degraded mountain area
(2009-05)
Active gully systems developed on highly weathered or loose parent material are an important source of runoff and sediment production in degraded areas. However, a decrease of land pressure may lead to a return of a partial ...
