Soil contamination is a problem that exists in many locations around the world. Soil can be contaminated by a variety of chemicals or microorganisms. The most common soil pollutants are pesticides, heavy metals, hydrocarbons and microplastics. Appropriate methods must be developed to remove such contaminants from soils, as they alter the physical, chemical, and biological nature of the soil and make it unsuitable for plant growth and/or human use. One method is to use plants that absorb and store pollutants from the soil. In this work, the concentration at which different plants absorb different possible metals (e.g. copper) and microplastic was investigated. Within a controlled atmosphere, parsley and mustard plants were grown. The finite concentration of the metals was introduced in the soil used for plantation. After harvesting plants thermal and electrochemical methods for the recovery of metals were employed. The resulting samples before and after were characterised using the ICP-MS method to determine the concentration of the contaminants. This reports the feasibility of these processes to recover metal contaminants from the soil. The success of the approach represents a replicable alternative soil remediation solution to heavy metal and other pollutants from industrial waste and illegal mining areas in most developing countries. First field trials are carried out in Ghana.
