(Beyond Pesticides, August 13, 2010) A new study finds that silver nanoparticles, which are used in consumer products and in hospitals for their antimicrobial properties, can harm plant life when it enters into the natural environment. Where silver nanoparticles are present in the soil, plant species are reduced by 22 percent, with an additional 20 [...]
(Beyond Pesticides, May 5, 2010) Canada has banned nanotechnology in organic food production. An amendment was added to Canada’s national organic rules banning nanotechnology as a “Prohibited Substance or Method.” The section lists substances or techniques that are prohibited in organic food production, including genetic engineering, synthetic pesticides, irradiation, and cloned animals, among others. In [...]
(Beyond Pesticides, May 3, 2010) Researchers have found that silver nanoparticles can migrate out of fabrics that have been treated with the particles for its antibacterial properties when it is exposed to simulated perspiration, raising concerns about human exposure to nanosilver through skin absorption. This is the first study to use artificial sweat to mimic [...]
(Beyond Pesticides, March 4, 2010) Scientists at Purdue University have found that nanosilver that is sonicated or suspended in solution is toxic and even lethal to fathead minnows, an organism that is often used to measure toxicity on aquatic life. The study is the latest research to demonstrate the need for federal regulatory agencies to [...]
(Beyond Pesticides, December 14, 2009) A new report links disinfectant chemicals with chronic illnesses and conditions such as asthma, hormone imbalance, and immune system problems. The report, Disinfectant Overkill: How Too Clean May Be Hazardous to Our Health, was released by the national environmental health group Women’s Voices for the Earth (WVE), and cites more [...]
(Beyond Pesticides, October 23, 2009) The U.S. Environmental Protection Agency (EPA) fined Samsung for violating the federal pesticide law when it publicized that its keyboards, produced with nanosilver, were antimicrobial and inhibited germs and bacteria without registering its products with EPA. The claims made on the company’s labels and promotional material for netbook and notebook [...]
(Beyond Pesticides, October 14, 2009) New research by scientists at the Swiss Federal Laboratories for Materials Testing and Research provides a first look at the behavior of nanosilver textiles under real-world washing conditions. This work builds on earlier studies conducted in water which show that nanosilver leaches from fabrics and textiles during washing to enter [...]
(Beyond Pesticides, September 24, 2009) The U.S. Environmental Protection Agency (EPA) has just announced that it filed suit against San Leandro based VF Corporation for the sale and distribution of unregistered pesticides through its retail company, The North Face. An AgION silver treated footbed, which the company claims has antimicrobial properties, is featured in over [...]
(Beyond Pesticides, August 28, 2009) Nanotech consumer products have now crossed the millennial threshold. Over 1,000 nanotechnology-enabled products have been made available to consumers around the world, according to the Project on Emerging Nanotechnologies (PEN). The most recent update to the group’s three-and-a-half-year-old inventory reflects the increasing use of the tiny particles in everything from [...]
(Beyond Pesticides, November 24, 2008) Acknowledging the critical need for in-depth review of products utilizing nanotechnology pesticides, the Environmental Protection Agency (EPA) opened a 60-day public comment period in response to a petition filed by the International Center for Technology Assessment (ICTA) which demands the agency stop the sale of numerous consumer products with nano-silver. [...]
(Beyond Pesticides, September 12, 2008) Widespread use of nanoscale silver will challenge regulatory agencies to balance important potential benefits against the possibility of significant environmental risk, highlighting the need to identify research priorities concerning this emerging technology, according to a new report released this week by the Project on Emerging Nanotechnologies (PEN). However, existing information [...]
(Beyond Pesticides, May 2, 2008) The International Center for Technology Assessment (CTA) and a coalition of consumer, health, and environmental groups, including Beyond Pesticides, yesterday filed a legal petition with the Environmental Protection Agency (EPA), demanding the agency use its pesticide regulation authority to stop the sale of 250+ consumer products now using nanosized versions of [...]
(Beyond Pesticides, April 30, 2008) New research shows that socks impregnated with silver nanoparticles to keep them microbe and odor free, release these particles when washed. Once washed down the drain, the silver particles enter the environment where they may pose numerable unknown adverse effects. Researchers from Arizona State University report their findings in a [...]
(Beyond Pesticides, January 14, 2008) Researchers at the Indian Institute of Technology (IIT) Madras have developed nanoparticles that can remove organochlorine pesticides from drinking water. These chemicals are quite persistent in the environment and difficult to remove from water. Notorious organochlorines include DDT, endosulfan, HCH (hexacholorcyclohexane) and aldrin, all of which have known health and/or [...]
(Beyond Pesticides, September 26, 2007) In a Federal Register Notice issued on September 21, 2007, the U.S. EPA clarified the distinction between devices and pesticides by stating that ion-generating equipment will now be regulated under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) as a pesticide, if the equipment uses electrodes to emit ions (of [...]
(Beyond Pesticides, August 23, 2007) With the joint release on July 31, 2007 of Principles for the Oversight of Nanotechnologies and Nanomaterials, a broad international coalition of 40 consumer, public health, environmental, and labor organizations called for strong, comprehensive oversight of the new technology and its products, citing risks to the public, workers and the [...]
