European Trade Union Institute Publishes Policy Brief on EUON

Posted in International, Legal/Regulatory Issues, Occupational Health and Safety Issues

The European Trade Union Institute (ETUI) recently published a policy brief entitled “EU Observatory for Nanomaterials:  a constructive view on future regulation.”  The policy brief provides information about the European Union (EU) Observatory for Nanomaterials (EUON), how it is being developed, its limitations, and “why it is not an ideal option.”  According to the policy brief, the absence of risk information regarding nanomaterials in safety data sheets (SDS) “is one of the main reasons why trade unions, environmental associations and consumer groups are in favour of a nano-registry, similar to those already established in several Member States such as France, Belgium, Denmark and Sweden (countries which make up a large part of the EU nano-market).”  The policy brief states that the European Chemicals Agency (ECHA) “should focus on its core business by demanding registration dossiers of sufficient quality on nanomaterials or the nanoform of substances” under the Registration, Evaluation, Authorization and Restriction of Chemicals (REACH) regulation.  The EUON should support ECHA by making information on risks and health effects more widely available to employers.  The policy brief suggests a different monitoring scenario, based on rules that would ensure transparency, improve the ability of national authorities to track different types of nanomaterials along the supply chain, make information visible, and guarantee an adequate exchange of information on safety at all stages.  ETUI’s recommendations include creating a framework to trace where nanomaterials are being produced and how they are used, and establishing worker exposure registries at the company level.  The policy brief “urges policy-makers to make use of foresight and ethics to address fast-moving technological convergence and the new frontiers of science and technology.”

New York Household Cleansing Product Information Disclosure Program Could Target Nanomaterials

Posted in Legal/Regulatory Issues, State, United States

As reported in our October 20, 2017, memorandum, “California and New York Require Manufacturers to Disclose Ingredients in Cleaning Products,” on April 25, 2017, New York Governor Andrew Cuomo (D) announced the Household Cleansing Product Information Disclosure Program.  The Program will require manufacturers of household cleansing products sold in New York to disclose the chemical ingredients on their websites.  Under the draft 2017 Household Cleansing Product Information Disclosure Program Certification Form and Guidance Document, information regarding certain ingredients, including nanomaterials, would have to be disclosed.  The draft Guidance states:  “For each ingredient that is a nanomaterial, a term describing the nanomaterial should be disclosed.  For example, if the nanomaterial is carbon, the disclosure should use the term ‘nano’ carbon.”  Comments on the draft Guidance were due July 14, 2017.  Final Guidance is expected soon.

2017 SNO Conference Will Be Held November 5-7

Posted in Legal/Regulatory Issues, United States

The Sixth Sustainable Nanotechnology Organization (SNO) Conference will be held November 5-7, 2017, in Los Angeles, California.  According to SNO, the Conference sessions represent a hybrid of topics on selected “systems” that contribute to sustainability and more traditional topics.  Sessions will be populated with talks on applications, effects and implications, analytical methods, and lifecycle aspects of nanomaterials within each system.  The aims are to identity where nanomaterials and nanotechnology can improve the sustainability of each system and to foster integration of knowledge between applications and implications within each system.  Topics from prior conferences will be addressed under the current session topics.  The Conference sessions include:

  1. Tribute to Pedro Alvarez: Pedro Alvarez has significantly contributed to eco-responsible nanotechnology through pioneering research on how engineered nanomaterials interact with bacteria, elucidating their mode of action and discerning potential impacts to microbial ecosystem services.  He also opened new opportunities for nano-enabled greener disinfection and biofouling control, as well as for enhanced (selective) removal of priority water pollutants.  Recently, Alvarez led a multi-university effort to establish a National Science Foundation Nanosystems Engineering Research Center for Nanotechnology-Enabled Water Treatment, which is developing easy-to-deploy, next-generation modular treatment processes that protect lives and support sustainable development;
  2. Food/Agriculture: This session centers on nanotechnology for food production, pesticide delivery, nutrient delivery, disease suppression, food fortification, and environmental implications;
  3. Water: This session focuses on applications of nanotechnology to address water or air contaminants, including applications in water supply, wastewater treatment, and industrial air quality control;
  4. Fate and Exposure: This session will consider studies addressing nanomaterial release, fate and transport, transformations, and exposure modelling;
  5. Nanotoxicology: This session emphasizes the evaluation of the effects (i.e., positive or negative) that advanced nanomaterials have on the environment and human health;
  6. Life-Cycle: It is important to consider a life-cycle perspective when evaluating the applications of nanotechnology, from raw materials to synthesis, and from product use to end of life.  Papers in this session can address the entire life-cycle of particular applications, or the implications in specific life-cycle phases, including recycling;
  7. Sensors/Measurement: Papers in this session focus on the need to develop sensors, new instruments, approaches, and/or further refinement of existing tools for characterizing nanomaterials and using nanomaterials as sensors to detect chemicals of interest;
  8. Green Synthesis: This session focuses on the synthesis of nanomaterials with lowered energy and fewer polluting by-products and starting materials;
  9. Education/Social Aspects: Papers in this session will address nano-education programs and curriculum development.  In addition, societal aspects, such as laws, regulations, economics, and social issues, will be covered; and
  10. Nanomedicine: This session will accept papers that deal with the use of various types of nanoparticles for use in medicine, particularly to diagnose and treat cancer.

EPA Publishes SNUR for MWCNTs (Generic)

Posted in Federal, Legal/Regulatory Issues, Occupational Health and Safety Issues, Research, United States

The U.S. Environmental Protection Agency published on October 19, 2017, a direct final rule promulgating significant new use rules (SNUR) for 29 chemical substances that were the subject of premanufacture notices (PMN).  The 29 chemical substances are subject to consent orders issued by EPA under Section 5(e) of the Toxic Substances Control Act.  The direct final rule includes a SNUR for multi-walled carbon nanotubes (MWCNT) (generic) (PMN Numbers P-15-487, P-15-488, P-15-489, P-15-490, and P-15-491).  According to the Federal Register notice, the PMN substances will be used as additives for electro-static discharge in electronic devices, electronics, and materials; additives for weight reduction in materials; additives to improve mechanical properties or electrical conductivities; heat-generating elements in heating devices and materials; additives for heat transfer and thermal emissions in electronic devices and materials; semi-conductor, conductive, or resistive elements in electronic circuitry and devices; additives to improve conductivity in electronic circuitry, energy storage systems, and devices; electron emitters for lighting and x-ray sources; additives for electromagnetic interface shielding in electronic devices; additives for electrodes in electronic materials and electronic devices; catalyst support in chemical manufacturing; coating additives to improve corrosion resistance or conductive properties; additives for fibers in structural and electrical applications; additives for fibers in fabrics and textiles; filter additives to remove nanoscale materials; semi-conducting compounding additives far high-voltage cable; and additives for super-hydrophobicity.  The consent order requires:

  1. Use of personal protective equipment to prevent dermal exposure and a National Institute for Occupational Safety and Health-certified respirator with N-100, P-100, or R-100 cartridges with an assigned protection factor of at least 50 (where there is a potential for inhalation exposure);
  2. Use of the PMN substances only for the uses specified in the consent order;
  3. No use in application methods that generate a dust, mist, or aerosol unless such application method occurs in an enclosed process; and
  4. No use of the PMN substances resulting in releases to surface waters and disposal of the PMN substances only by landfill or incineration.

A significant new use is any use involving an application method that generates a dust, mist, or aerosol.  The SNUR requirements do not apply when the PMN substances have been incorporated into a polymer matrix that has been reacted (cured) or embedded in a permanent solid polymer form that is not intended to undergo further processing except mechanical processing.  EPA states that it determined that a subchronic 90-day inhalation toxicity study (OPPTS 870.3465 or OECD 413), a two-year inhalation bioassay (OPPTS 870.4200), a fish early-life stage toxicity test (OCSPP Test Guideline 850.1400), a daphnid chronic toxicity test (OCSPP Test Guideline 850.1300), and an algal toxicity test (OCSPP Test Guideline 850.4500) would help characterize possible health and environmental effects of the substances.  Although the consent order does not require these tests, EPA notes that the order’s restrictions on manufacture, processing, distribution in commerce, and disposal will remain in effect until the order is modified or revoked by EPA based on submission of this or other relevant information.

OECD Releases Test Guidelines Specifically Developed to Address Nanomaterials

Posted in OECD, Research

On October 12, 2017, the Organization for Economic Cooperation and Development (OECD) announced the release of 17 new, updated, corrected, or deleted Test Guidelines.  The Test Guidelines include three specifically developed for nanomaterials.  OECD states that Test Guideline 318:  Dispersion Stability of Nanomaterials in Simulated Environmental Media provides a simple and effective tool that can analyze the dispersion stability of nanomaterials in aqueous media.  It is one of the prerequisites for a subsequent robust and reliable safety testing of nanomaterials.  The Test Guideline allows users to understand nanomaterials’ fate in natural waters and their potential behavior in test media.  OECD updated Test Guideline 412:  28-Day (Subacute) Inhalation Toxicity Study and Test Guideline 413:  90-Day (Subchronic) Inhalation Toxicity Study to allow testing and hazard identification of inhaled nanomaterials.  According to OECD, the updates concern bronchoalveolar lavage measurements; particle-size distribution for test atmospheres; post-administration duration; and lung burden measurements.  OECD states that the information that will be gathered through these new endpoints make the Test Guidelines applicable for assessing potential inhalation hazards of nanomaterials, while also increasing the understanding on the mode of action by which nanomaterials may act.

EC Proposes to Amend REACH Annexes to Address Nanomaterials

Posted in International, Legal/Regulatory Issues

On October 9, 2017, the European Commission (EC) began a public consultation on a draft regulation that would amend Annexes I, III, VI, VII, VIII, IX, X, XI, and XII of the Registration, Evaluation, Authorization and Restriction of Chemicals (REACH) regulation to address nanoforms of substances.  The draft regulation states that:

  • Clarifications to requirements for the registration of substances with nanoforms and related downstream user obligations should be included in Annexes I, III, and VI to XII;
  • Manufacturers and importers should assess and, where relevant, generate the necessary information and document in the chemical safety report that the risks arising from the identified uses of the substance with nanoforms are adequately controlled;
  • As the majority of nanomaterials are expected to be nanoforms of phase-in substances, the conditions for the requirements for generation of new toxicological and ecotoxicological information on phase-in low volume substances should be elaborated to ensure that the assessment criteria are based also on the predicted properties of nanoforms;
  • All different nanoforms and sets of nanoforms should be considered by the registrant in the demonstration of safety;
  • To allow efficient assessment of the potential exposure for inhalable nanoforms, in particular in workplaces, information on dustiness should be provided for the different nanoforms or sets of nanoforms;
  • Although acute toxicity testing for the lowest tonnage is required via the oral route, for nanoforms, inhalation or in very specific cases the dermal route may be considered as a more appropriate route of exposure;
  • A number of specific physico-chemical properties, in addition to those used to identify the different nanoform or sets of nanoforms, may be considered relevant for scientific understanding of the properties of a nanomaterial, with the necessary parameters depending on the individual case. For reasons of workability and proportionality, only registrants for higher volume substances than 100 tonnes per year should be required to consider explicitly such further information in case other particle properties significantly influence hazard or exposure to those nanoforms; and
  • Compliance with the provisions of the proposed amendment should not be required immediately to allow all registrants and downstream users adequate time to adapt to the more specific requirements for substances with nanoforms. The amendment would apply from January 1, 2020.

Comments are due November 6, 2017.
