Effects of dredging operations on sediment quality: contaminant mobilization in dredged sediments from the Port of Santos, SP, Brazil
(Springer Heidelberg, 2009-10-01)
Background, aim, and scope Contaminated sediments are a worldwide problem, and mobilization of contaminants is one of the most critical issues in environmental risk assessment insofar as dredging projects are concerned. ...

Dredging impacts on the toxicity and development of sediment quality values in a semi-arid region (Ceará state, NE Brazil)
(2021-02-01)
Sediment dredging impacts coastal environments by promoting the resuspension of fine particles and remobilization of contaminants that may trigger toxic effects. In this study, we evaluated the sediment quality in harbor ...
Short term impact of artisanal dredges in a Patagonian mussel fishery: Comparisons with commercial diving and control sites
(Elsevier, 2012-02)
Mussels in the San Matías Gulf fishery are targeted using artisanal dredges and diving. The main objective of this study was to assess the direct impact of artisanal dredging on the biota and sediments, and to compare the ...
Ecotoxicological assessment of sediments from the Port of Santos and the disposal sites of dredged material
(Universidade de São Paulo (USP), Instituto Oceanográfico, 2007-06-01)
A dragagem dos sedimentos do Canal de Santos é necessária para permitir o trânsito de navios que operam no Porto de Santos. As áreas de disposição do material dragado estão situadas na zona costeira, em frente à Baía de ...

Effects of Green Waste Compost Addition to Dredged Sediments of the Matanza-Riachuelo River (Argentina) on Heavy Metal Extractability and Bioaccumulation in Lettuce (Lactuca sativa)
(Springer, 2021-05)
Soil amendments can be an effective and low-cost treatment to reduce metal bioavailability of contaminated dredged sediments disposed on land. The effect of green waste compost addition on Cu, Cr, Ni, Pb, and Zn extractability ...
Efeitos da dragagem sobre a qualidade de sedimentos contaminados do canal do porto de Santos : biodisponibilidade e toxicidade de metais e compostos orgânicos persistentes
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Química - PPGQ, 2007-10-19)
Contaminated sediments is a worldwide problem, and mobilization of contaminants is one of the most critical issue in environmental risk assessment when dredging projects are concerned. Considering this, we decided to ...
Contamination of port zone sediments by metals from Large Marine Ecosystems of Brazil
(Pergamon-Elsevier B.V. Ltd, 2012-03-01)
Sediment contamination by metals poses risks to coastal ecosystems and is considered to be problematic to dredging operations. In Brazil, there are differences in sedimentology along the Large Marine Ecosystems in relation ...
