Nanomaterials can serve as effective tools for cleanup of contaminated sites

Washington, July 9 (ANI): In a new research, scientists have determined that nanomaterials can serve as effective and economically viable tools for the cleanup of contaminated sites.

The research is detailed in new review article appearing in Environmental Health Perspectives (EHP) co-authored by Dr. Todd Kuiken, a research associate for the Project on Emerging Nanotechnologies (PEN).

It provides an overview of current practices; research findings; societal issues; potential environment, health, and safety implications; and possible future directions for nanoremediation.

According to Dr. Todd Kuiken, "Despite the potentially high performance and low cost of nanoremediation, more research is needed to understand and prevent any potential adverse environmental impacts, particularly studies on full-scale ecosystem-wide impacts. To date, little research has been done."

Supplemental material published with the EHP review identifies 45 sites where nanomaterials have been used for soil and groundwater remediation, covering seven countries and 12 US states.

Most of the materials discussed are a form of nano-scale zero-valent iron that are injected into the ground in a slurry which provide a reducing environment that enables the breakdown of contaminants.

To coincide with the release of the EHP article, PEN has for the first time made publicly available an interactive, online map of global nanoremediation sites.

The map shows which nanomaterials have been used where and includes detailed information on the contaminants treated and the nature of the treatment.

It provides a unique source of information on the intentional release of nanomaterials into the environment to treat contaminated ground and water. (ANI)
