Wang, Z.; Li, B.; Sun, Y.; Yang, W. Leaching remediation of dredged marine sediments contaminated with heavy metals. 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. ; Prica, M.D. ; Souza, I.D.C. ; Domini, C.E.

The role of planting in the restoration of southern pine ecosystems that are underrepresented on the landscape is simple to the point of being rudimentary--when a seed source of the desired species is absent from a stand, planting is the only way to re-establish the desired species in the stand being restored. Newly planted forests improve land degraded by mining, growing crops, and over-grazing livestock. At present, resource-oriented utilization is classified as ecosystem restoration, construction materials, and agricultural activities. Falciglia, P.P.
