Like many other new technologies, all of the big promises that nanotechnology has made still remain to be seen and there are still big unanswered questions about their potentially harmful effects on our health and the environment. OSU labs have tested more than 200 nanomaterials, and while they report that very few posed concern, some were found to be highly toxic. <\/p>\n<p>There is much reason to be cautious, especially since a <a href=\"https:\/\/www.beyondpesticides.org\/dailynewsblog\/?p=4186\">recent study<\/a> found that nanosilver can interrupt important cell signaling within male reproductive sperm cells, causing them to stop growing. Previous studies have shown that the particles, which are between one and 100 nanometers in size and smaller than many viruses, can enter the environment through wastewater, where they can accumulate in biosolids at wastewater treatment plants. These biosolids, also known as sewage sludge, are often sold to consumers as fertilizer, despite the fact that they can contain <a href=\"https:\/\/www.beyondpesticides.org\/dailynewsblog\/?p=4064\">toxic contaminants<\/a>. Nanosized particles can also be released from impregnated materials via <a href=\"https:\/\/www.beyondpesticides.org\/dailynewsblog\/?p=338\">washing<\/a> or or as a result of <a href=\"https:\/\/www.beyondpesticides.org\/dailynewsblog\/?p=3548\">sweating<\/a>, posing unknown adverse effects to humans and <a href=\"https:\/\/www.beyondpesticides.org\/dailynewsblog\/?p=3228\">water systems<\/a>. <\/p>\n<p>Some of the concerns that researchers highlight include the potential need for new methodologies from traditional chemical tests in order to fully understand the effects of nano sized particles. They also call for full disclosure from manufacturers on exactly what nanoparticles are involved in their products and what their characteristics are. They also say that special assessments are needed for sensitive populations, such as infants, the elderly or fetal exposure to nanoparticles. <\/p>\n<p>Another issue is to ensure that compounds are tested in the same way humans would be exposed in the real world. Dr. David Stone, PhD, an assistant professor in the OSU Department of Environmental and Molecular Toxicology explains: \u201cYou can\u2019t use oral ingestion of a pesticide by a laboratory rat and assume that will tell you what happens when a human inhales the same substance. Exposure of the respiratory tract to nanoparticles is one of our key concerns, and we have to test compounds that way.\u201d<\/p>\n<p>Researchers also say that future regulations need to acknowledge the additional level of uncertainty that will exist for nano-based pesticides with inadequate data and want tests to be done using the commercial form of the pesticides and a health surveillance program as well as other public educational programs should be developed. They conclude that there needs to be a \u201ccoordinated effort between governmental, industry, academic and public entities to effectively deal with a revolutionary class of novel pesticides.\u201d<\/p>\n<p>Back in 2007 a broad international coalition of 40 consumer, public health, environmental, and labor organizations, including Beyond Pesticides, released the <em><a href=\"https:\/\/www.beyondpesticides.org\/nanotechnology\/Principles%20for%20the%20Oversight.pdf\">Principles for the Oversight of Nanotechnologies and Nanomaterials<\/a><\/em>, calling for strong, comprehensive oversight of the new technology and its products. Beyond Pesticides has since advocated for a precautionary course of action in order to prevent unnecessary risks to the public, workers and the environment. <\/p>\n<p>Earlier this year, <a href=\"https:\/\/www.beyondpesticides.org\/dailynewsblog\/?p=3564\">Canada <\/a>joined several other countries that have either banned or proposed a ban on nanotechnology in organic recognizing the potential risks that have yet to be addressed. These countries include the United Kingdom\u2019s Soil Association, Biological Farmers of Australia, and Austrian organic certifier Austria Bio Garantie. In the U.S., the National Organic Standards Board (NOSB) heard testimony on the development of a <a href=\"http:\/\/www.ams.usda.gov\/AMSv1.0\/getfile?dDocName=STELPRDC5083223&#038;acct=nosb\">definition and policy on nanotechnology<\/a> in organic standards earlier this year and the US-based Organic Crop Improvement Association has added a clause in their organic standard to regulate the use of nanotechnology. <\/p>\n<p>For more information on nanomaterials, see Beyond Pesticides\u2019 <a href=\"https:\/\/www.beyondpesticides.org\/antibacterial\/nano.htm\">nanosilver page<\/a> or <a href=\"https:\/\/www.beyondpesticides.org\/dailynewsblog\/?cat=90\">nanotechnology news alerts<\/a>.  <\/p>\n<p><em>Source: <a href=\"http:\/\/oregonstate.edu\/ua\/ncs\/archives\/2010\/oct\/new-approaches-needed-gauge-safety-nanotech-based-pesticides\">Oregon State University<\/a><\/em><br \/>\n<\/font><\/p>\n","protected":false},"excerpt":{"rendered":"<p>(Beyond Pesticides, October 7, 2010) Nanotechnology has played an increasing role in the world of pesticides, particularly in the form of silver nanoparticles for their antibacterial properties; however, as this field grows, scientists and researchers are becoming increasingly concerned with the potential impacts of these particles on public health and the environment.

The founders, who established Beyond Pesticides (originally as National Coalition Against the Misuse of Pesticides) as a nonprofit membership organization in 1981, felt that without the existence of such an organized, national network, local, state and national pesticide policy would become, under chemical industry pressure, increasingly unresponsive to public health and environmental concerns. Beyond Pesticides believes that people must have a voice in decisions that affect them directly. We believe decisions should not be made for us by chemical companies or by decision-makers who either do not have all of the facts or refuse to consider them. Learn more about our work, read A Year in Review\u20142021, our accomplishments are your victories! Beyond Pesticides seeks to protect healthy air, water, land, and food for ourselves and future generations. By forging ties with governments, nonprofits, and people who rely on these natural resources, we reduce the need for unnecessary pesticide use and protect public health and the environment. Beyond Pesticides provides hands-on services to the public and supports local action by: identifying and interpreting hazards; and, designing safe pest management programs. With the information provided by Beyond Pesticides, people may not only be able to make informed choices and adopt practices that protect themselves and their families from unnecessary exposure to pesticides, but they will be able to effect changes on community-wide pest management decisions and policies that govern pesticide use, such as pesticide uses in parks, schools, for community insect control and along roadsides.

The founders, who established Beyond Pesticides (originally as National Coalition Against the Misuse of Pesticides) as a nonprofit membership organization in 1981, felt that without the existence of such an organized, national network, local, state and national pesticide policy would become, under chemical industry pressure, increasingly unresponsive to public health and environmental concerns. Beyond Pesticides believes that people must have a voice in decisions that affect them directly. We believe decisions should not be made for us by chemical companies or by decision-makers who either do not have all of the facts or refuse to consider them. Learn more about our work, read A Year in Review\u20142021, our accomplishments are your victories! Beyond Pesticides seeks to protect healthy air, water, land, and food for ourselves and future generations. By forging ties with governments, nonprofits, and people who rely on these natural resources, we reduce the need for unnecessary pesticide use and protect public health and the environment. Beyond Pesticides provides hands-on services to the public and supports local action by: identifying and interpreting hazards; and, designing safe pest management programs. With the information provided by Beyond Pesticides, people may not only be able to make informed choices and adopt practices that protect themselves and their families from unnecessary exposure to pesticides, but they will be able to effect changes on community-wide pest management decisions and policies that govern pesticide use, such as pesticide uses in parks, schools, for community insect control and along roadsides. Beyond Pesticides believes that people must have a voice in decisions which affect them directly.","sameAs":["https:\/\/www.beyondpesticides.org","https:\/\/www.facebook.com\/beyondpesticides\/","https:\/\/www.instagram.com\/beyondpesticides\/","https:\/\/www.linkedin.com\/company\/beyond-pesticides\/","https:\/\/x.com\/ByondPesticides","https:\/\/www.youtube.com\/user\/bpncamp\/"],"url":"https:\/\/beyondpesticides.org\/dailynewsblog\/author\/beyond-pesticides\/"}]}},"_links":{"self":[{"href":"https:\/\/beyondpesticides.org\/dailynewsblog\/wp-json\/wp\/v2\/posts\/4353","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/beyondpesticides.org\/dailynewsblog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/beyondpesticides.org\/dailynewsblog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/beyondpesticides.org\/dailynewsblog\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/beyondpesticides.org\/dailynewsblog\/wp-json\/wp\/v2\/comments?post=4353"}],"version-history":[{"count":7,"href":"https:\/\/beyondpesticides.org\/dailynewsblog\/wp-json\/wp\/v2\/posts\/4353\/revisions"}],"predecessor-version":[{"id":4360,"href":"https:\/\/beyondpesticides.org\/dailynewsblog\/wp-json\/wp\/v2\/posts\/4353\/revisions\/4360"}],"wp:attachment":[{"href":"https:\/\/beyondpesticides.org\/dailynewsblog\/wp-json\/wp\/v2\/media?parent=4353"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/beyondpesticides.org\/dailynewsblog\/wp-json\/wp\/v2\/categories?post=4353"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/beyondpesticides.org\/dailynewsblog\/wp-json\/wp\/v2\/tags?post=4353"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
