Nanoparticle News recently published a short article about a voluntary NIOSH field study of potential worker exposure to nanoscale materials at a California company late last year. According to the article, the company manufactures nanoscale metals and metal oxides for use in the energy, electronics, and defense industries. Apparently, with NIOSH's help the company was able to reduce potential workplace emissions of engineered nanoparticles by 90%. Based on final test results, the company "concluded that no further action [was] necessary to reduce engineered nanoscale materials emissions, during the manufacture of nanomaterials, in order to protect the safety of employees and the environment."

The hyperbolic article appears designed to scare consumers into believing they are unknowingly consuming nanoparticles:
"[i]n the absence of mandatory product labelling, public debate or laws to ensure their safety, products created using nanotechnology have entered the food chain."
Furthering a grand conspiracy theory, FOE claims "[s]ecrecy surrounds the commercial use of nanotechnology and nanomaterials by the food industry."
Of apparent primary concern to FOE are nanoscale particles of silver, titanium dioxide, zinc, and zinc oxide. FOE estimates that there are already 150-600 foods containing nanomaterials and 400-500 food packaging/contact applications using nanotechnology. These products purportedly include nutritional supplements, nutritional drinks, cooking equipment, kitchenware, food packaging, food additives, and plant growth treatments. FOE's article also lists 29 major food and agriculture companies involved in "nanotechnology research and development," and 104 purported nano food and food-related products.
While we agree eating metallic and/or metal oxide nanoscale materials is probably not a good idea, we believe FOE has gone overboard in suggesting consumers are somehow unknowingly wolfing down nanoparticles.
Nevertheless, FOE calls for a: (i) "moratorium until nano-specific safety laws are established with public input;" (ii) treating engineered nanoscale materials as “new substances;” (iii) rigorous nano-specific testing before nanomaterials may be used in "foods, food packaging, food contact materials, or agricultural products;" (iv) increasing the upper size-limit of any regulatory definition of “nano” to 300 nm; (v) complete transparency in publishing safety assessment data; (vi) clear nano-product labeling; and (vii) public involvement in all nano-decision making processes.
Inside OSHA reports that the AFL-CIO, United Steelworkers, and Center to Protect Workers Rights recently asked NIOSH to develop a "basic medical screening protocol for industry where workers are faced with potential exposure to nano-sized materials," and to implement a "nanotechnology exposure registry and undertake a full-scale national nanotechnology health surveillance program."
As regular readers may recall, last December NIOSH published an "Interim Guidance for the Medical Screening of Workers Potentially Exposed to Engineered Nanoparticles." That document found "[n]o substantial link … between occupational exposure to engineered nanoparticles and adverse health effects." Accordingly, NIOSH stated its believe that "insufficient medical evidence exists at this time to recommend the specific medical screening of workers potentially exposed to engineered nanoparticles."
For those of you on the West Coast, you may want to look into a 1/2-day Summit that was just announced to address regulatory efforts regarding nanotechnology. "The Future of Nanotechnology: a legislative summit" is described as, "the first step for stakeholders from industry, government, research institutes and environmental groups to discuss responsible ways to regulate nanotechnology without stifling progress." It is being hosted by Assemblymember Mike Feuer (AD 42 - D), UCLA's Office of the Vice Chancellor for Research (OVCR), the State Government Relations (SGR), and the California Nanosystems Institute (CNSI).

MIT's Technology Review just published its list of Top Ten Emerging Technologies for 2008. One of the top ten items is NanoRadio. TR's description of NanoRadio begins with:
If you own a sleek iPod Nano, you've got nothing on Alex Zettl. The physicist at the University of California, Berkeley, and his colleagues have come up with a nanoscale radio, in which the key circuitry consists of a single carbon nanotube.
Absolutely fascinating -- and especially so since this technology could be considered one of the first true "nano-machines." As an aside, nanotechnology-related technologies have made the "TR10" for each of the past three years -- 2007 (Nanohealing), 2006 (Nanomedicine and Nanobiomechanics), and 2005 (quantum wires).

2. Outline environmental applications in the context of emerging consumer products, pollution prevention, risk reduction, and remediation.
3. Assess the suitability of multicriteria decision analysis for reconciliation of benefits and risks of nanotechnology.
4. Direct future research in nanomaterial and environmental sciences to address the emerging issues associated with nanotechnology in general and specifically with emerging nano-enabled consumer products.
5. Identify strategies for users in developing countries to best manage this emerging technology and its associated risks.
Conference sponsors include: NATO, Society for Risk Analysis (SRA), US Army Engineer Research and Development Center, International Copper Association, US Environmental Protection Agency, International Council on Nanotechnology, European Nanotechnology Trade Alliance, and Faculty from the University of Algarve.
Lloyd's of London recently issued another nano-related insurance document: D. Baxter, "Nanotechnology: An insurer's perspective," Emerging Risks, Lloyd's of London.
First, Lloyd's notes that several types of insurance may be impacted by potential EHS risks related to nanotechnology including: (i) professional indemnity, (ii) medical malpractice, (iii) director's and officer's liability, (iv) general liability, (v) employer's liability, and (vi) product liability.
Lloyd's then identifies several possible coverage options for insurers seeking to deal with these potential risks:
Finally, Lloyd's recommends insurers ask their nano-insureds the following questions: (i) what nanotechnologies does the company use?: (ii) what are the known hazards of those materials?; (iii) what are potential hazards of those materials?; (iv) has the material's toxicity been studied?; (v) has its environmental impact been studied?; (vi) does the company follow any voluntary nano-specific EHS guidelines? (vii) has the company performed a life-cycle assessment related to its use of nanomaterials?; and (viii) does the insured advise its customers about its use of nanotechnology?

(i) Whether nanoparticles are potentially hazardous to workers. NIOSH admits "[l]ittle information is available about the hazards of nanoparticles in the workplace," and believes the following categories of information are necessary to adequately evaluate potential workplace exposure risks: type and concentration of nanoparticles; relevant toxicological properties; and dose concentrations. On this same issue, NIOSH acknowledges that there are some adverse animal studies regarding certain types of nanoparticles, but that human exposure studies are not currently available. NIOSH further notes that "[f]ire and explosion are the main safety hazards associated with nanoparticles in the workplace," and there are "[n]o US or international exposure standards." Accordingly, NIOSH recommends a "prudent approach to minimize possible worker exposure until more information is available."
(ii) Possible exposure routes. NIOSH identifies three possible exposure routes to nanomaterials in the workplace: (i) inhalation (most common); (ii) ingestion (hand-to-mouth and/or respiratory tract); and (iii) skin ("Some studies mention that nanoparticles may penetrate skin.") NIOSH perhaps downplays the controversy surrounding this last issue.
(iii) Measurement techniques. NIOSH believes traditional industrial hygiene measurement methods will be effective. However, NIOSH notes that scientists are currently developing better and more sensitive sampling techniques for ambient nanoparticles.
(iv) Exposure control. NIOSH recommends using engineering controls to reduce possible exposure to nanomaterials. These include source exposure controls, local exhaust ventilation, and HEPA filtration. NIOSH also notes that "[r]espirators should be considered if engineering and administrative controls do not control worker exposure to nanoparticles." Finally, NIOSH recognizes that good worker training is an important part of any exposure reduction program.
NIOSH concludes the brochure with a link back to its draft 2006 document -- "Approaches to Safe Nanotechnology: An Information Exchange with NIOSH."
The Congerssional Research Service recently issued a report on nanotechnology regulatory issues to Congress:
L. Schierow, Congressional Research Service Report for Congress, "Engineered Nanoscale Particles and Derivative Products: Regulatory Challenges," January 22, 2008.
CRS begins its reoprt by noting that "enthusiasm and investment in nanotechnology are somewhat restrained . . . by questions about the possible environmental, human health, and safety (EHS) risks associated with this new technology." CRS predicts that there may be great costs to the nanotechnology industry -- both monetarily and reputational -- if the public indiscriminately rejects nanotechnology as a whole because of an adverse incident involving a single nanoscale material.
CRS then notes several challenges facing any attempt by Congress to regulate nanotechnology: (i) lack of data characterizing nanomaterials; (ii) lack of standardization in nomenclature, metrics, and materials; (iii) proprietary nature of information; (iv) difficulty of communicating among academic disciplines; (v) limited resources; and (vi) possible inadequate statutory authority.
After briefly explaining the above difficulties, CRS identifies four possible approaches for Congress to use in controlling potential EHS risks posed by certain nanoscale materials:
1. Increase research and standardization funding. CRS takes the position that "[a]ccording to the Chairman of the House Subcommittee on Research and Science Education of the Committee on Science, 'the basic position of most outside observers from industry and non-governmental organizations is that the funding level should be on the order of 10% of the initiative's (NNI) total funding, rather than the current 4%.'" CRS does not breakdown how these new proposed research funds should be spent.
2. Reallocate existing federal research funding. CRS suggests reevaluating how nano-EHS research money is divided between federal agencies given priority research topics. CRS leaves it to NSF and NNI to determine whether and how such reallocation is appropriate.
3. Adopt a national or international research strategy. CRS notes this approach is difficult to implement without first conducting comprehensive EHS research. CRS further notes that when NNI/NEHI created their general nano-EHS-research framework in 2007, they identified five research categories and some specific needs, but they did not prioritize between these needs.
4. Enact legislation: information collection; restrictions on production, sale, use, and/or disposal. CRS notes existing EHS laws are probably adequate to govern the potential risks posed by nanotechnology, but they were not written with nanomaterials in mind. As a result, agencies may need to develop new policies, produce guidance documents, and possibly issue regulations to make existing statutes applicable to nanomaterials. CRS recognizes that any new regulations need to be implemented in phases. Further, CRS posits that to "reduce the burden imposed by a testing requirement, Congress might allow manufacturers to share test data (and costs of testing), grant exclusive production or marketing rights within the United States for a number of years to manufacturers who conduct testing (to compensate them for their expenditures), or exempt particular categories of products or manufacturers from requirements."
CRS concludes that "[i]t is noteworthy that Congress is considering its options at this early stage of technology development, when only a few nanomaterials are being manufactured on a large scale. Risk management decisions nonetheless are pressing, as the rate of nanotechnology development and commercialization is rapidly escalating."
