US CDC Publishes Safety Nanotechnology Guidance

Citing concern over the occupational risks that potentially exist in nanotechnology, the US CDC has issued a safety guidance manual for the nanotechnology.


"Research has shown that materials on this small scale begin to exhibit physical, chemical, and biological behaviors that are quite unique. These unique properties raise concerns about the health impacts of nanotechnology, particularly among workers employed in nanotechnology-related industries."

The threshold length for fibre-induced acute pleural inflammation: shedding light on the early events in asbestos-induced mesothelioma

Recent research implicates nanoparticles or nanofibres as a potential health hazard:

"Suspicion has been raised that high aspect ratio nanoparticles or nanofibres might possess asbestos-like pathogenicity. The pleural space is a specific target for disease in individuals exposed to asbestos and, by implication nanofibres. Pleural effects of fibres depends on fibre length, but the key threshold length beyond which adverse effects occur has never been identified up to now since all asbestos and vitreous fibre samples are heterogeneously distributed in their length. Nanotechnology advantageously allows for highly defined length distribution of synthetically engineered fibres which enable for in depth investigation of this threshold length. We utilised the ability to prepare silver-nanofibres of five defined length classes to demonstrate a threshold fibre length for acute pleural inflammation. Nickel-nanofibres and carbon nanotubes were then used to strengthen the relationship between fibre length and pleural inflammation. A method of intrapleural injection of nanofibres in female C57Bl/6 strain mice was used to deliver the fibre dose and we then assessed the acute pleural inflammatory response. Chestwall sections were examined by light and by scanning electron microscopy to identify areas of lesion; furthermore cell-nanowires interaction on the mesothelial surface of the parietal pleura in vivo, were investigated. Our results showed a clear threshold effect demonstrating that fibres beyond 4 µm in length are pathogenic to the pleura. The identification of the threshold length for nanofibre induced pathogenicity in the pleura has important implications for understanding the structure-toxicity relationship for asbestos-induced mesothelioma and consequent risk assessment with the aim to contribute to the engineering of synthetic nanofibres by the adoption of a benign-by-design approach."

Carbon Nanotubes Exposure Linked to Lung Tumor Formation in Mice

"Earlier today, at the annual meeting of the Society of Toxicology, NIOSH researchers reported preliminary findings from a new laboratory study in which mice were exposed by inhalation to multi-walled carbon nanotubes (MWCNT).  The study was designed to investigate whether these tiny particles have potential to initiate or promote cancer.  

By “initiate,” we mean the ability of a substance to cause mutations in DNA that can lead to tumors.  By “promote,” we mean the ability of a substance to cause cells that have already sustained such DNA mutations to then become tumors. "

EPA Takes Action to Protect Public from an Illegal Nano Silver Pesticide in Food Containers; Cites NJ Company for Selling Food Containers with an Unregistered Pesticide Warns Large Retailers Not to...

Today's post was shared by US EPA News and comes from yosemite.epa.gov

 The U.S. Environmental Protection Agency has issued an order to the Pathway Investment Corp. of Englewood, New Jersey to stop the sale of plastic food storage containers that have not been tested or registered with the EPA, in violation of federal pesticides law. The company’s Kinetic Go Green Premium Food Storage Containers and Kinetic Smartwist Series Containers both contain nano silver as an active ingredient, and the company markets other products as containing nano silver, which the company claims helps reduce the growth of mold, fungus and bacteria. Such claims can only be made on products that have been properly tested and are registered with the EPA.

“Claims that mold, fungus or bacteria are controlled or destroyed by a particular product must be backed up with testing so that consumers know that the products do what the labels say,” said EPA Regional Administrator Judith A. Enck. “Unless these products are registered with the EPA, consumers have no information about whether the claims are accurate. The EPA will continue to take action against companies making unverified public health claims.”

Some pesticides have been linked to various forms of illnesses in people, ranging from skin and eye irritation to cancer. Some pesticides may also affect the hormone or endocrine systems. In many situations, there are non-chemical methods that will effectively control pests.

Limits for Toxic Plastics – No Asbestos Ban


Today, the Basel, Rotterdam, and Stockholm United Nations Conventions concluded, with some major steps taken by parties to control the trade and management of certain toxic chemicals: 

Basel Convention: Countries Take Major Step to Control Plastic Waste Dumping, Stop Major Loophole for Electronic Waste
Today, 187 countries took a major step forward in curbing the plastic waste crisis by adding plastic to the Basel Convention, a treaty that controls the movement of hazardous waste from one country to another. The amendments, originally proposed by Norway, require exporters to obtain the consent of receiving countries before shipping most contaminated, mixed, or unrecyclable plastic waste, providing an important tool for countries in the Global South to stop the dumping of unwanted plastic waste into their country. The decision reflects a growing recognition around the world of the toxic impacts of plastic and the plastic waste trade.

Because the US is not a party to the Convention, the amendments adopted today also act as an export ban on unsorted, unclean, or contaminated plastic waste for the US towards developing countries who are parties to the Convention and not part of the OECD. The amendment will have a similar effect for the EU, a party to the Convention, whose own internal legislation bans exports of waste included under the Convention to developing countries.

“Today’s decision demonstrates that countries are finally catching up with the urgency and magnitude of the plastic pollution issue and shows what ambitious international leadership looks like,” says David Azoulay, Environmental Health Director at the Center for International Environmental Law (CIEL). “Plastic pollution in general and plastic waste in particular remain a major threat to people and the planet, but we are encouraged by the decision of the Basel Convention as we look to the future bold decisions that will be needed to tackle plastic pollution at its roots, starting with reducing production.”
 
Countries halted a major loophole that would have allowed the continued export of electronic waste (e-waste), without proper controls. The proposed guidelines describing how e-waste is treated under the Basel Convention would have allowed countries to send equipment for repair without the prior informed consent procedure. The guidelines were ready for adoption, with wide support. The African region, India, and other countries, supported by civil society, raised a red flag about the inclusion of this loophole, and countries chose to continue negotiating the guidelines at the next COP, instead of adopting ineffective guidelines.
 
Countries established Low POPs Content Levels (LPCLs), which define the amount of POPs at which waste is considered hazardous waste. Under this designation, the waste must be disposed of in a way that destroys or irreversibly transforms its POPs content. LPCLs are key: Higher values mean that dangerous materials can, in practice, be recycled into everyday products, triggering further exposure to very toxic POPs. Mobilizing against very high values proposed by the EU, African countries and other recipient countries of waste managed to resist the extreme pressure from the EU and other developed countries, and obtained the inclusion of lower values together with the higher values proposed by the EU, opening the way for future work to lower the levels of POPs allowed in waste even further.
 
Parties considered a report on the role of the Basel Convention to regulate waste containing nanomaterials. It recommended the inclusion of certain nano-containing waste under the Basel Convention, and invited further work to identify those wastes that should be covered by the Convention. In a disappointing move, parties adopted a weak decision only requiring the collection of information on national initiatives to address nano-containing waste.

Stockholm Convention: Countries Pass Global Ban on Toxic PFOA
Parties to the Stockholm Convention passed a global ban of PFOA — a suspected carcinogen and endocrine disruptor that has contaminated drinking water in many parts of the world. The Stockholm Convention regulates persistent organic pollutants (POPs), some of the world’s worst chemicals that harm human health and build up in the environment and the body over time.

“While the global ban on PFOA marks an important step forward in protecting the environment and people’s health, we regret that countries undermined the scientific process of the Convention to include unjustified exemptions to the ban,” said Giulia Carlini, Staff Attorney at CIEL.

A number of wide-ranging five-year exemptions were included in the PFOA ban for firefighting foams, medical devices, and fluorinated polymers, among other uses. Though China, the European Union, and Iran participated in the scientific review process, they proposed exemptions that had not undergone scientific review or were reviewed and disqualified by the scientific committee.

“PFOA is one of the world’s worst chemicals, and yet countries have found ways to continue human exposure to its toxic harms. Tellingly, even some industry groups disagreed with some of the exemptions, as there are widely available alternatives to these chemicals,” says Carlini. “Countries’ insistence on including these exemptions — in spite of readily available alternatives and a lack of evidence — reveals a disrespect for the scientific review process at the heart of the Stockholm Convention.”

Rotterdam Convention: Countries Break 15 Years of Gridlock Using Voting Procedure for First Time Ever
In the first-ever vote taken under the Rotterdam Convention, 120 parties to the Stockholm Convention broke through gridlock and disagreement to establish a compliance mechanism for the Convention. The compliance mechanism will allow countries to be held accountable for not respecting their commitments under the Convention. After nearly 15 years of negotiations with little forward movement, countries decided that “all efforts to reach consensus had been exhausted” and opted instead to vote, for the first time in the history of the Convention. The adoption of the new mechanism through a vote means that only those parties in agreement to the provisions will be be subject to this mechanism. A total of 126 Parties voted, of which 120 agreed to the compliance mechanism and only six opposed.
 
Countries listed hexabromocyclododecane (HBCD), a toxic chemical used as a flame retardant, and phorate, a pesticide that is extremely toxic to humans, under the Rotterdam Convention’s Annex III, meaning that countries must get the prior informed consent of receiving countries in order to export these chemicals.
 
Unfortunately, countries failed to take action on the five other chemicals up for listing under Annex III of the Convention. In particular, chrysotile asbestos and paraquat, which have been reviewed and identified as chemicals of concerns by the Scientific Chemical Review Committee of the Convention, and have been on the agenda for years. A handful of countries repeatedly blocked the consensus required to list these chemicals under the Convention, undermining the scientific process underlying the Convention.

NIOSH Schedules Conference on Safety of Nanoparticles

NIOSH announced a conference in July 2010 to discuss the safety concerns that have been raised concerning workers and nanotechnology.

NIOSH research has shown that some nanoparticles, including certain types of carbon nanotubes and metal oxides, can be toxic to the heart and lung in mice and rats in laboratory experiments. Other research has demonstrated various other adverse effects of nanoparticles. Through its Approaches to Safe Nanotechnology, NIOSH recommends that specific precautions be taken to protect workers who might be exposed to any level of nanoparticles or nanoparticle-containing materials. A big question left unanswered is, can nanoparticles cause the same types of disease in humans?”

Concern intensified on this issue following the publication of the September issue of the “European Respiratory Journal, the first medical case series of workers with serious disease that the study authors associate with exposure to nano-sized particles has been published.”

US EPA Seeks Input About Lead Contamination in Public and Commercial Buildings

The U.S. Environmental Protection Agency (EPA) is inviting small businesses to participate as consultants for a Small Business Advocacy Review (SBAR) Panel as the agency considers steps to reduce lead based paint exposure from the renovation, repair, and painting of public and commercial buildings as required by section 402(c)(3) of the Toxic Substances Control Act (TSCA).

The SBAR Panel is being established pursuant to the Regulatory Flexibility Act, and will include representatives from the Small Business Administration (SBA), the Office of Management and Budget (OMB), and EPA. The Panel will ask a selected group of Small Entity Representatives (SERs) to provide advice and recommendations on behalf of their company, community, or organization to inform the Panel on impacts of a proposed rule on small entities involved in the renovation, repair, and painting of public and commercial buildings. SER panelists may participate via telephone or webinar, as well as in person.

EPA seeks self-nominations directly from the small businesses, small governments and small organizations that may be subject to the rule requirements to facilitate the selection of SERs. An entity is eligible to be a SER if it will be directly subject to the particular proposed regulation under development and meets one of the SBA’s definitions http://www.sba.gov/content/table-small-business-size-standards
to qualify as a small entity.

EPA encourages the actual owners or operators of small businesses, community officials, and representatives of non-profit organizations to participate in this process. However, a person from a trade association that exclusively or primarily represents potentially regulated small entities may also serve as a SER.

Self-nominations may be submitted through the link below and must be received by May 9, 2014.

These Two Desks Could Help You Live Longer

These Two Desks Could Help You Live Longer
Today's post is shared from yahoo.com
Have you heard the latest bad news? Sitting is the new smoking.
According to one study, every workday you spend sitting costs you 2.5 hours off your lifespan. Sit six hours a day, and you’ll die 4.8 years sooner. It’s true even if you exercise regularly; this article explains why.
Sitting also makes you fat, reduces bone density, contributes to heart disease, and makes you less productive. Great.
These statistics are heaven-sent for the makers of standing desks — tall desks where you work standing — and sit/stand desks, which move up and down so you can split your time between sitting and standing. That’s supposed to be the healthiest arrangement of all.
Unfortunately, first-generation hand-cranked sit/stand desks are the modern equivalent of treadmills: health equipment you buy with the best of intentions but wind up not using (except to drape clothing on).
Ironically, the lazy person’s powered sit/stand desk, which goes up and down at the touch of a button, is much more likely to be used and therefore to yield better health results.
The Stir Kinetic Desk
Enter the Stir Kinetic Desk, the brainchild of JP Labrosse, a former Apple designer (he worked on the iPod Shuffle, among other projects). This baby fits right in with the Tesla sports car, Nest thermostat, and MacBook Air in a special circle of exquisitely designed, ultra-high-tech everyday goods that come at nosebleed prices.
