Use and implications of iron and other transition metals in environmental remediation processes

This is an excerpt from the content

A large variety of contaminants are currently found in surface water, groundwater, and soil, including organic solvents, hydrocarbons and halogenated hydrocarbons, pesticides, pharmaceuticals, personal care products, and heavy metals. These contaminants become of special concern given their extensive use and the severe threats they cause to human health, aquatic life, and the environment. In light of this, a great deal of research has been performed in order to develop technologies capable of cleaning up contaminated matrices. In general, remediation technologies can be grouped into categories using thermal, physicochemical, chemical, or biological methods. Due to the complex nature of many contaminated systems, development of remediation methods that could clean all types of contaminants becomes a great challenge. The traditional technologies can be effective, but very often are costly and time-consuming. Thus, the removal of contaminants to a safe level, while at the same time rapidl
