Elements of a framework for

sustainable regulation and oversight of ENPs

The Applications of Nanotechnology for Safe and Sustainable Environmental Remediation (Nano-4-Rem ANSSERS) informatics initiative is an initiative designed to understand and meet information and technology needs of emerging Engineered Nanoparticles (ENPs)

The Nano-4-Rem is one step closer to prevent exposure and human health risks from ENPs in nano-enhanced remediation and by extension, in other areas where ENPs are used. This work can be accomplished by professionals, industry, academia, and government who will collaborate to:

• Organize information available, to share perspectives and pose relevant and specific questions related to Nano-4-Rem

• Discuss best practices and guidelines, and the selection of ENPs or best available technology (BAT) for specific applications. Prevention of ecological catastrophic ecological impacts is one of the expectations from these discussions leading to empowering local agencies regulatory and oversight of ENPs

• Creating a network of opportunities for inter and intra institution research and teaching, and promote sharing of knowledge

Laws governing the remediation of contaminated soils or water include: the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), and the Resource Conservation and Recovery Act (RCRA)

Current traditional remediation technologies: pump-and-treat and permeable reactive barriers (PRBs) etc.

Newer , emerging and innovative remediation methods now include use of engineered nanoparticles (ENPs). ENPs used for Rem include nano zero-valent iron, bimetallic nZVI/Pd/carbon nanosystems, and titanium dioxide.

ENPs advantages may be time-savings and cost-effectiveness for remediation of bioaccumulative toxic and persistence substances.

Advances in nanotechnology-enabled assessment and monitoring methods such as nano-sensors may improve remediation activities.

Recent studies show association between exposure to ENPs and significant health risks and ecological impacts

Recalling the impacts of DDT and PCBs decades ago, compels to do something now about ENPs

Many more areas where ENPs are used are emerging!
