Along with the Cubans love for music, there is a love for dance as well. Privacy Policy In rocks, they occur as minerals in different chemical forms, such as sulfides and oxides [, As heavy metals are transported into the water, most fractions (>90%) are trapped in sediments by adsorption, precipitation, complexation, and chelation reactions [, Traditionally, remediation of metal-contaminated sediments has been achieved through in situ and ex situ treatment [, Sediment washing extracts metals from dredged sediment to the washing solution through high-pressure water jets or adding some chemical washing agents (such as inorganic acid, chelators, and surfactants) (, EKR can be applied both in situ and ex situ, which involves inserting electrodes into a contaminated medium and applying an electric field to move the contaminant towards the electrodes [, Floatation is a possible technique for remediation of dredge sediment, which is obviously affected by the sediment properties (e.g., particle size), bubbles, and extraction agents [, Recently, microwave and ultrasonic-assisted heavy metal extractions have been emerging, which have the advantages of labor-less, time-saving, lower reagents usage, reduced contamination, and enhanced operator safety in comparison with conventional chemical extraction (, Ex situ phytoremediation seems to have strong potential for treatment contaminated sediments. ; Torre, A.G.D.L.
