【 摘 要 】

Both interstitial water and plant tissue associated with the DC-A substrate exhibited low metal concentrations. Also in agreement with the previous study, plant performance in the DC-A substrate was found to be comparable to plant performance in the dredge spoil and topsoil substrates. This was extremely important because it indicated that the drill cuttings themselves served as an excellent substrate for wetland plant growth, but that the processing and stabilization techniques and drilling fluid formulations required further refinement.
