The sediment samples were then analyzed for triclosan, the four dioxins that are derived from triclosan and the entire family of dioxin chemicals.  <\/p>\n<p>In papers published in 2003 and 2009, Dr. Arnold and Dr. McNeill discovered that triclosan, when exposed to sunlight, generated a specific suite of four dioxins. <a href=\"https:\/\/www.beyondpesticides.org\/news\/daily_news_archive\/2001\/01_26_01.htm\">Dioxin<\/a> refers to a family of chemicals linked to cancer, weakened immune systems and reproductive problems. They are persistent organic pollutants that bioaccumulate in humans and other animals, especially in fatty tissue. Dioxin can be highly carcinogenic and can cause health problems as severe as weakening of the immune system, decreased fertility, altered sex hormones, miscarriage, birth defects, and cancer. Because of the chemical structure as a polychloro phenoxy phenol, it is possible that dioxin can be found in triclosan as synthesis impurities. In addition to being formed during the manufacturing process, dioxin may also be formed upon incineration of triclosan. <\/p>\n<p>\u201cThese four dioxins [found in the sediment core samples] only come from triclosan. They didn\u2019t exist in Lake Pepin before triclosan was introduced,\u201d Dr. Arnold said in a Science Daily news release. \u201cIn the most current sediments, these triclosan-derived dioxins account for about 30 percent of the total dioxin mass.\u201d <\/p>\n<p>Triclosan is one of the <a href=\"https:\/\/www.beyondpesticides.org\/dailynewsblog\/?p=306\">most detected<\/a> chemicals in U.S. waterways; according to the study, about 96 percent of triclosan from consumer products is disposed of in residential drains. This leads to large loads of the chemical in water entering wastewater treatment plants, which are incompletely removed during the wastewater treatment process. When treated wastewater is released to the environment, sunlight converts some of the triclosan (and related compounds) into dioxins. Researchers believe that triclosan and the dioxins ended up in Lake Pepin sediments by sticking to organic particles in the river, which then sank when they reached the calmer waters of the lake. Additionally, Triclosan can combine with chlorine in tap water to form chloroform, which is listed as a probable human carcinogen. <\/p>\n<p>There are many additional human health and environmental hazards associated with the extensive use of triclosan. Triclosan is an endocrine disruptor and has been shown to affect male and female reproductive hormones, which could potentially increase risk for breast cancer. Triclosan is also shown to alter <a href=\"https:\/\/www.beyondpesticides.org\/dailynewsblog\/?p=1004\">thyroid function<\/a>, and other studies have found that due to its extensive use in consumer goods, triclosan and its metabolites are present in, fish, umbilical cord blood and <a href=\"https:\/\/www.beyondpesticides.org\/dailynewsblog\/?p=268\">human milk<\/a>. <a href=\"https:\/\/www.beyondpesticides.org\/dailynewsblog\/?p=248\">Another study<\/a> found that triclosan was present in the urine of 75% of the U.S. population, with higher levels in people in their third decade of life and among people with the highest household income. <\/p>\n<p>Beyond Pesticides, in partnership with Food and Water Watch and 78 other groups, submitted <a href=\"https:\/\/www.beyondpesticides.org\/dailynewsblog\/?p=2972\">petitions<\/a> to both the <a href=\"https:\/\/www.beyondpesticides.org\/documents\/triclosan%20fda%20petition%207-14.pdf\">FDA<\/a> and <a href=\"https:\/\/www.beyondpesticides.org\/antibacterial\/triclosan-epa-petition.pdf\">EPA<\/a> requiring that they all non-medically prescribed triclosan uses on the basis that those uses violate several federal statutes. Prompted by this petition, which was then echoed by Rep. Markey\u2019s (D-MA) <a href=\"https:\/\/www.beyondpesticides.org\/dailynewsblog\/?p=2915\">letters of concern<\/a>, the FDA <a href=\"https:\/\/www.beyondpesticides.org\/dailynewsblog\/?p=3420\">responded<\/a>, \u201cexisting data raise valid concerns about the [health] effects of repetitive daily human exposure to these antiseptic ingredients,\u201d and announced plans to address the use of triclosan in cosmetics or other products. EPA, however, in its response maintains that the agency does not currently plan to reevaluate its regulations surrounding the use of triclosan until 2013.<\/p>\n<p>Since the 2004 publication of \u201c<a href=\"https:\/\/www.beyondpesticides.org\/pesticides\/factsheets\/Triclosan%20cited.pdf\">The Ubiquitous Triclosan<\/a>,\u201d Beyond Pesticides has been exposing the dangers of this toxic chemical. Now, along with Food and Water Watch and over 80 environmental and public health groups, Beyond Pesticides is leading a national grassroots movement calling for the ban of triclosan from consumer products. Beyond Pesticides is calling on manufacturers, retailers, school districts, local businesses and communities to wash their hands of triclosan and protect our nation\u2019s waters and public health from this toxic pesticide.

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\/3631","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=3631"}],"version-history":[{"count":3,"href":"https:\/\/beyondpesticides.org\/dailynewsblog\/wp-json\/wp\/v2\/posts\/3631\/revisions"}],"predecessor-version":[{"id":3634,"href":"https:\/\/beyondpesticides.org\/dailynewsblog\/wp-json\/wp\/v2\/posts\/3631\/revisions\/3634"}],"wp:attachment":[{"href":"https:\/\/beyondpesticides.org\/dailynewsblog\/wp-json\/wp\/v2\/media?parent=3631"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/beyondpesticides.org\/dailynewsblog\/wp-json\/wp\/v2\/categories?post=3631"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/beyondpesticides.org\/dailynewsblog\/wp-json\/wp\/v2\/tags?post=3631"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
