By Porter Wright on The first phase of EPA’s voluntary Nanoscale Materials Stewardship Program (NMSP) closes on Monday. For those keeping track, the most up-to-date NMSP participation statistics as of July 24, 2008 follow. It is shaping up to be a very respectable list of participants. Submissions Under Basic Program: (9 submissions – covering 68 nanoscale materials) DuPont; Nanophase Technologies Corporation; … Continue Reading
By Porter Wright on A new Lux Research quarterly report — "Nanomaterials State of the Market Q3 2008: Stealth Success, Broad Impact" — contains a section summarizing the state of nano-related environmental, health, and safety issues in the United States. The report contains a very helpful time-line of key nano-related EHS events occurring between the fourth quarter of 2007 … Continue Reading
By Porter Wright on A February 2008 study published by six Stanford scientists examined the long term fate of intravenously injected carbon nanotubes in mice. The scientists’ goal was to measure the circulation of SWCNTs in the bloodstream and to determine whether they accumulate in organs and/or tissues. At the same time, the scientists also studied the effects of … Continue Reading
By Porter Wright on There have been a number of articles published since May 20 regarding a possible link between carbon nanotubes and the development of precursors of mesothelioma because of a recent letter published in Nature Nanotechnology. C. Poland, et al., "Carbon nanotubes introduced into the abdominal cavity of mice show asbestos-like pathology in a pilot study," Nature Nanotechnology, May 20, … Continue Reading
By Porter Wright on Last week we told you about the just-opened REACH pre-registrations here. Now, the news from across the pond tells us that carbon and graphite are to be specifically included in the REACH submissions.… Continue Reading
By Porter Wright on Researchers at the Georgia Institute of Technology (Georgia Tech) have discovered that multi walled carbon nanotubes will remain suspended in water for a month or longer when combined with other organic materials. The January issue of the journal Environmental Science & Technology , will fully report the findings by Assistant Professor Jaehong Kim, Professor Joseph Hughes, … Continue Reading
