Release of particles and metals into seawater following sediment resuspension of a coastal mine tailings disposal off Portmán Bay, Southern Spain

A method to reproduce pH and Eh environmental changes due to sediment resuspension

“…The dredge intensification related to world economic development increased the concern with possible ecosystem damages due to sediment resuspension, this encouraged research to pursue knowledge over the sediment metals release process and kinetic. In order to predict those metals release impacts, several resuspension experiments were developed during the last Decades [ 1 , 2 , [5] , [6] , [7] , 9 , 11 , 13 ].…”

“…Most of these experiments are based on the oxidation of the sediment, in a variety of methods. Oxidation by agitation is the most common, however, other oxidation processes are also performed, such as using an air pump or pumping oxygen directly from a gas cylinder [ 2 , 8 ]. Mostly related to biogeochemical studies, microcosmos is also used to simulate environmental Physico-chemical changes [ 4 , 10 ].…”
