The talk focused on the problems synthetic pyrethroids and fipronil can have on Hyalella azteca and Chironomus dilutes. Increasing levels of pesticide runoff in local stream systems have not only led to decreased populations of these aquatic crustaceans, but also populations that have become resistant to pesticides. Aquatic invertebrates are extremely sensitive to pesticide runoff and different states around the country have struggled with creating pesticide regulations that foster a healthy aquatic ecosystem. A good way to reduce pesticide runoff is to transition away from toxic land care methods and adopt organic practices.<\/p>\n<p>Hyalella crustaceans, a tiny shrimp-like animal, are hypersensitive to <a href=\"https:\/\/www.beyondpesticides.org\/pesticides\/factsheets\/Synthetic%20Pyrethroids.pdf\">pyrethroids<\/a>, which are a class of insecticides used by professional lawn care companies and found in common products like Raid and mixed with fertilizer products like Scotts Turf Builder under the name SummerGuard. Chironomus dilutes, a red worm-like invertebrate, is sensitive to<a href=\"https:\/\/www.beyondpesticides.org\/gateway\/index.php?pname=fipronil.php\"> fipronil<\/a>, which is used to kill fleas on dogs and cats and on lawns to control ants and termites. Currently, Contra County, California professional pest control operators use \u00a013,300 pounds of pesticides, which do not include pesticides used by private citizens. Hyalella curstaceasn, which live in Contra County creeks, are exposed to such high levels of these chemicals that they have begun building resistance to pyrethroids.<\/p>\n<p>Dr. Weston was quoted in a <a href=\"http:\/\/www.mercurynews.com\/my-town\/ci_25896446\/contra-costa-county-creeks-increasingly-poisoned-by-pesticide\">San Jose Mercury News article<\/a> \u00a0saying, \u201cIt scares us, because that tells us there&#8217;s enough pyrethroid in the creek to cause them to mutate. The sensitive pests have been killed off; the rest have mutated and survived.&#8221;<\/p>\n<p><a href=\"https:\/\/www.beyondpesticides.org\/dailynewsblog\/?p=3135\">Previous studies<\/a> performed by Dr. Weston have found pyrethroids at high levels in streams throughout California. Urban runoff data, taken between 2006 and 2010, showed all communities in the Sacramento area and the Bay Area had toxic levels, especially after a rainfall. Dr. Weston first began looking at pyrethroid levels in<a href=\"https:\/\/www.beyondpesticides.org\/news\/daily_news_archive\/2004\/05_10_04.php\"> streams bordering farm fields in 2004<\/a>, and reported levels in some creek sediments high enough to kill Hyalella curstaceasns, which are used by the U.S. Environmental Protection Agency (EPA) as an indicator of the health of freshwater sediment.<\/p>\n<p>The streams have become so contaminated with pyrethroids that, according to Dr. Weston, &#8220;We&#8217;d have to flood the county 6,046 feet deep to dilute it enough so that Hyalella could live. That&#8217;s equal to two Mount Diablos, stacked on top of each other.&#8221;<\/p>\n<p>Pyrethroids are synthetic versions of pyrethrin, a natural insecticide found in certain species of chrysanthemum. It initially was introduced on the market as a \u201d\u02dcsafer\u2019 alternative to the highly toxic \u00a0<a href=\"https:\/\/www.beyondpesticides.org\/dailynewsblog\/index.php?s=organophosphates\">organophosphates<\/a>, \u00a0such as <a href=\"https:\/\/www.beyondpesticides.org\/gateway\/pesticide\/chlorpyrifos.htm\">chlorpyrifos<\/a> \u00a0and \u00a0<a href=\"https:\/\/www.beyondpesticides.org\/gateway\/pesticide\/diazinon.htm\">diazinon<\/a> \u00a0which were banned for homeowner use in 2001 and 2004, respectively. They are now one of the most popular class of household pesticides, available in the form of powders and sprays to control ants, mosquitoes, fleas, flies, and cockroaches. Pyrethroids are dangerous to aquatic life even at concentrations used to eliminate mosquitoes. Of the varieties of pyrethroids used, <a href=\"https:\/\/www.beyondpesticides.org\/gateway\/index.php?pname=bifenthrin.php\">befinthrin<\/a> was most commonly found in \u00a0previous research conducted \u00a0by Dr. Weston.<\/p>\n<p><a href=\"https:\/\/www.beyondpesticides.org\/pesticides\/factsheets\/Fipronil.pdf\">Fipronil<\/a>, a broad spectrum insecticide, was first introduced in the U.S. in 1996 and is highly toxic to aquatic life. and understood not \u00a0to be readily biodegradable. In water and sediment that lack oxygen, fipronil degrades more slowly, with a half-life of 116-130 days and its breakdown products are also considered to be highly toxic to aquatic organisms. Beyond it being incredibly toxic to fresh water invertebrates, it is also <a href=\"https:\/\/www.beyondpesticides.org\/dailynewsblog\/?p=5910\">highly toxic to bees<\/a>.<\/p>\n<p>Other states besides California have also struggled with the effects that pesticides can have on aquatic invertebrates. \u00a0<a href=\"https:\/\/www.beyondpesticides.org\/dailynewsblog\/?p=11003\">Last summer<\/a>, \u00a0Connecticut Governor Daniel Malloy signed into law \u00a0<a href=\"http:\/\/www.cga.ct.gov\/asp\/cgabillstatus\/cgabillstatus.asp?selBillType=Bill&amp;bill_num=6441&amp;which_year=2013&amp;SUBMIT1.x=10&amp;SUBMIT1.y=18&amp;SUBMIT1=Normal\">House Bill 6441<\/a>, \u00a0which banned <a href=\"https:\/\/www.beyondpesticides.org\/gateway\/?pesticideid=219\">methoprene<\/a> \u00a0and<a href=\"https:\/\/www.beyondpesticides.org\/gateway\/index.php?pesticideid=267\"> \u00a0resmethrin<\/a>, a pyrethroid insecticide, \u00a0in coastal areas such as the Long Island Sound because of declines in lobster populations. Declines in the \u00a0Sound\u2019s lobster population have been \u00a0<a href=\"https:\/\/www.beyondpesticides.org\/dailynewsblog\/?p=1263\">alarmingly common<\/a> \u00a0for the past 15 years, devastating fishermen and the local economy that depends on them. \u00a0Connecticut legislators say that they were convinced that banning the two mosquito pesticides after learning that Rhode Island and Massachusetts had enacted similar bans with successful results. \u00a0<a href=\"https:\/\/www.beyondpesticides.org\/dailynewsblog\/?p=11665\">A similar bill<\/a> \u00a0to ban the use of methoprene was also introduced in Suffolk County, New York last summer.<\/p>\n<p>One way to help change this problem is to start managing your lawn organically.

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\/13400","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=13400"}],"version-history":[{"count":3,"href":"https:\/\/beyondpesticides.org\/dailynewsblog\/wp-json\/wp\/v2\/posts\/13400\/revisions"}],"predecessor-version":[{"id":13404,"href":"https:\/\/beyondpesticides.org\/dailynewsblog\/wp-json\/wp\/v2\/posts\/13400\/revisions\/13404"}],"wp:attachment":[{"href":"https:\/\/beyondpesticides.org\/dailynewsblog\/wp-json\/wp\/v2\/media?parent=13400"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/beyondpesticides.org\/dailynewsblog\/wp-json\/wp\/v2\/categories?post=13400"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/beyondpesticides.org\/dailynewsblog\/wp-json\/wp\/v2\/tags?post=13400"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
