American National Standards Institute’s (ANSI) nanotechnology standards panel to meet in Februrary 2013 and one more standard

The American National Standards Institute’s (ANSI) Nanotechnology Standards Panel (NSP) was scheduled to meet in Oct. 2012 but Hurricane Sandy, which hit the eastern part of the continent at that time, necessitated rescheduling to Feb. 4, 2013 as per the Dec. 20, 2012 posting on Thomas.net,

Originally scheduled for October 30, 2012, ANSI’s Nanotechnology Standards Panel meeting was postponed as a result of Hurricane Sandy and will now be held on February 4, 2013. Meeting will examine how current nanotechnology standards are being utilized and how standards activities meet existing stakeholder needs. Benefits of participating in nanotechnology standardization and the possibilities for greater collaboration between stakeholders in this area will also be discussed.

The Dec. 14, 2012 ANSI news release provides more details about the Feb. 4, 2012 meeting to be held in Washington, DC,

The half-day meeting will examine how current nanotechnology standards are being utilized and how standards activities meet existing stakeholder needs. The benefits for companies, organizations, and other groups to participate in nanotechnology standardization and the possibilities for greater collaboration between stakeholders in this area will also be discussed.

Formed in 2004, ANSI’s NSP serves as the cross-sector coordinating body for the facilitation of standards development in the area of nanotechnology. Shaun Clancy, Ph.D., the director of product regulatory services for the Evonik Degussa Corporation, and Ajit Jilavenkatesa, Ph.D., the senior standards policy advisor for the National Institute of Science and Technology (NIST) of the U.S. Department of Commerce (DoC), serve as the ANSI-NSP’s co-chairs.

… The ANSI-NSP works to provide a forum for standards developing organizations (SDOs), government entities, academia, and industry to identify needs and establish recommendations for the creation or updating of standards related to nanotechnology and nanomaterials. In addition, the ANSI-NSP solicits participation from nanotechnology-related groups that have not traditionally been involved in the voluntary consensus standards system, while also promoting cross-sector collaborative efforts.

Attendance at the February meeting is free. All attendees are required to register here for the meeting; individuals who registered for the October 2012 event must register again.

Standardization is one of the topics highlighted in Michael Berger’s Dec. 20, 2012 Nanowerk Spotlight article about environmental health and safety and a high-throughput screening (HTS) platform developed at the University of California’s Center for Environmental Implications of Nanotechnology (CEIN) that can perform toxicity screening of 24 metal oxide nanoparticles simultaneously,

According to the team, the HTS platform that has been demonstrated in this study could easily be adapted to study other nanomaterials of interest. The capability of HTS would also allow researchers to analyze multiple samples at different concentrations, time points, as well as varying experimental parameters – all in one setup. The standardization of the whole screening process by this HTS platform also minimizes human intervention and errors during the experiment.

I guess it’s the season for standardization. Ho, ho, ho!

New research on nanoscale titanium dioxide shows toxic effects on marine life

Up till now, nanoscale titanium dioxide in water has not been viewed as toxic to marine life. A newly released study by researchers from  the University of California (UC) Center for Environmental Implications of Nanotechnology (UC CEIN) in the Jan. 20 in the journal PLoS ONE suggests otherwise. From the Jan. 24, 2012 news release on EurekAlert,

“Previous experiments have suggested that TiO2 does not affect aquatic organisms, but these experiments used artificial lighting that generated much lower levels of UVR than sunlight,” Miller [lead author and assistant research biologist Robert Miller] explains. “In these new experiments, we used lights simulating natural sunlight.”

But now, the authors say, “We show that relatively low levels of ultraviolet light, consistent with those found in nature, can induce toxicity of TiO2 nanoparticles to marine phytoplankton, the most important primary producers on Earth.

So, the relatively low levels of ultraviolet light in natural sunlight can induce toxicity in titanium dioxide nanoparticles. Here’s the reason for the concern,

“Application of nanomaterials in consumer products and manufacturing is quickly increasing, but there is concern that these materials, including nanoparticles, may harm the environment,” says Miller. “The oceans could be most at risk, since wastewater and factory discharges ultimately end up there.”

In all of the kerfuffle that the Friends of the Earth (FoE) and The ETC Group (and I assume others as well) have made over nanoscale ingredients in sunscreens they seem to have ignored the impact that these ingredients, when washed off our skin and into our water supply, may have on aquatic life.  I wonder if that will matter in the end. I mean if it turns out that nanoscale titanium dioxide is going to kill/damage “… the most important primary producers on Earth”, does it matter if FoE and the others succeed in mobilizing opposition to its use for what most experts might consider the wrong reasons.
