(Beyond Pesticides, March 26, 2013) Scientists are learning more about the mechanisms bed bugs have developed to increase their resistance to the increasingly common class of pyrethriod pesticides. The study, published in the journal Scientific Reports in early March, adds further weight to calls from consumer health and environmental groups to adopt proven, non-toxic strategies [...]
(Beyond Pesticides, May 31, 2012) The Centers for Disease Control and Prevention (CDC) and the Maryland Department of Health and Mental Hygiene have enrolled Maryland households in a study that involves spraying the controversial pesticide bifenthrinon their property to determine the efficacy of this approach in controlling Lyme disease. Now in the beginning of its [...]
(Beyond Pesticides, January 31, 2012) The Environmental Protection Agency (EPA) has proposed an expansion in pyrethrins/pyrethroid insecticide uses as part of its cumulative risk assessment for this neurotoxic class of chemicals. In the cumulative risk assessment, EPA concludes that pyrethroids “do not pose risk concerns for children or adults,” ignoring a wealth of independent data [...]
(Beyond Pesticides, December 7, 2011) Aspen City, Colorado, is considering mandating pre-notification of pesticide use so that neighbors and passersby can avoid being exposed to possible toxic chemicals. The notification provides for a 48-hour notice before application, as well as information on the pesticide to be used and its potential health effects. However, the Council [...]
(Beyond Pesticides, November 16, 2011) On November 9, 2011, the U.S. Environmental Protection Agency (EPA) issued its cumulative risk assessment for the pyrethroid class of insecticides, concluding that these pesticides “do not pose risk concerns for children or adults,” ignoring a wealth of independent data that links this class of chemicals to certain cancers, respiratory [...]
(Beyond Pesticides, August 11, 2011) A combination of eleven different kinds of commonly used pyrethroids were tested on mice in a new study which found that, at real-world exposure levels, the insecticides can produce heightened toxicity that is equal to the sum of each insecticide’s individual effect. The mixture of similar-acting insecticides works by over-stimulating [...]
(Beyond Pesticides, March 10, 2010) A study investigating the sublethal effects of pyrethroids, bifenthrin and deltamethrin on honeybees finds that the chemicals significantly impair the pollinators’ reproduction. The researchers also point out that the concentration of each pesticide that produced adverse effects in the experiments was at or below those that bees could encounter while [...]
(Beyond Pesticides, February 16, 2010) Pyrethroids, among the most widely-used home pesticides, are winding up in California rivers at levels toxic to some stream-dwellers, possibly endangering the food supply of fish and other aquatic animals, according to a study by researchers at the University of California, Berkeley, and Southern Illinois University (SIU). The study, “Urban [...]
(Beyond Pesticides, July 17, 2009) High levels of pyrethroid pesticides in the Sacramento-San Joaquin River Delta, the number one river system on America’s Most Endangered Rivers List of 2009, has been linked to heavy urbanization in the region. Leading a study to understand the collapse of the delta’s ecosystem, University of California-Berkeley toxicologist Donald Weston, [...]
(Beyond Pesticides, December 10, 2008) Most families don’t realize that they might be bringing more than holiday cheer into their homes this Christmas season. Families celebrating this holiday season with the time-honored tradition of a Christmas tree can choose to go green and avoid the toxic chemicals that are typically used to grow it. Beyond [...]
(Beyond Pesticides, October 17, 2008) A study published in the September 15 issue of Environmental Science & Technology has found pyrethroid contamination in 100 percent of urban streams sampled. Synthetic Pyrethroids are one of the most widely used consumer pesticides, but recently they have been scrutinized for their resultant health and environmental effects. California is [...]
(Beyond Pesticides, August 1, 2008) The Oregon Department of Agriculture has released the 2007 Pesticide Use Reporting System (PURS) annual report, summarizing data collected last year -making it the first report to include information from a mandatory electronic reporting of pesticide use statewide. The requirement to report online applies to anyone using a registered pesticide [...]
(Beyond Pesticides, March 1, 2007) In 24 states throughout the country, beekeepers have been shocked to find that bees have been inexplicably disappearing at an alarming rate, according to an article in the New York Times last week. This loss of honeybees threatens not only beekeeper livelihoods but also the production of numerous crops, including [...]
