Abstract
Amongst environmental contamination problems, soil contamination with metals and metalloids may represent a big threat due to the high toxicity and widespread presence of mining activities. Electrokinetic (EK) process relies on the application of a low level direct current between electrodes in a partially saturated or even saturated soil and appears as a promising in situ strategy for fine-grained contaminated soils. Due to its mobilization potential, EK process can be considered as an integrated tool for contaminants removal, alone and coupled with phytoremediation. The coupling of EK process with phytoremediation (also known as EK-assisted phytoremediation) is an innovative technique that deserves a deeper knowledge to enlarge the scope of EK application. The EK-enhanced phytoremediation aims to use the presence of plants to counteract the effects of the electric current as it brings most of the benefits of a “regular” phytoremediation scheme (e.g., recovery of soil properties and improvement of its structure).
