Multiple <a href=\"https:\/\/www.beyondpesticides.org\/resources\/pesticide-induced-diseases-database\/body-burden\">studies on breast milk<\/a> have been performed throughout the years, many of them confirming the fact that common toxic chemicals, such as <a href=\"http:\/\/beyondpesticides.org\/dailynewsblog\/2014\/05\/moms-tell-epa-to-ban-glyphosate-after-residues-found-in-breast-milk\/\">glyphosate<\/a> and <a href=\"http:\/\/beyondpesticides.org\/dailynewsblog\/2008\/01\/antibacterial-found-in-plasma-and-milk-of-swedish-nursing-mothers\/\">triclosan<\/a>, build up in our bodies over time. Most people are unaware that they carry chemical compounds in their bodies, a natural phenomenon dubbed chemical \u201cbody burden.\u201d At any given time, hundreds of chemicals can be found in blood, urine, breast milk and even umbilical cord blood. Many of these chemicals enter our bodies through the foods we eat or drink, products we put on our skin and air we breathe. Before birth, people normally carry a body burden inherited from their mothers. Scientists believe the typical human being hosts close to 500 chemicals in various compartments in the body, mostly in fatty tissue. Many chemicals are broken down in our bodies and their metabolites are eliminated, but others linger in bodies for a lifetime and can increase the \u00a0risk of \u00a0certain diseases, such as \u00a0<a href=\"https:\/\/www.beyondpesticides.org\/resources\/pesticide-induced-diseases-database\/cancer\">cancer<\/a> \u00a0and \u00a0<a href=\"https:\/\/www.beyondpesticides.org\/resources\/pesticide-induced-diseases-database\/parkinsons-disease\">Parkinson&#8217;s disease<\/a>.<\/p>\n<p>For this study, researchers recruited 40 breastfeeding mothers and performed mass spectrometry tests to determine the levels at which their human milk (HM) showed the presence of 88 different pesticides. While traditional POPs, such as organochlorines, organophosphates, carbamates and pyrethroids, were not detected in HM, the study revealed that 87.5% of mothers tested positive for dichlorodiphenyldichloroethylene (DDE), the toxic chemical dichlorodiphenyltrichloroethane&#8217;s (DDT)\u2019s major metabolite. DDT was banned in the U.S. in 1972, following a massive environmental movement spurred by Rachel Carson\u2019s \u00a0<em>Silent Spring<\/em>, which documents the adverse environmental effects resulting from the indiscriminate use of pesticides. Despite the fact that DDT was banned in the U.S. 43 years ago, concentrations of DDE have remained alarmingly high in many ecosystems, a fact supported by the prevalence of DDE in HM reported in this study.<\/p>\n<p>Aside from the presence of DDE, the study does bring with it some positive findings, as researches point out that infants how have a daily intake of POPs 59-times below the amount that is considered safe. \u201cIt\u2019s really good news,\u201d said Professor Hartmann, Ph.D., while speaking to the problematic effects that \u00a0the presence of pesticides can have on the growth and development of babies, \u201csome of these compounds do mimic some of the body\u2019s hormones\u201d\u00a6 so it is a bit of a problem if they are at high levels.\u201d He also reiterated that his research showed that legislation to ban pesticides in the 1970\u2019s has had positive impacts on health. &#8220;The restriction of sale of these pesticides has had an enormous effect in bringing the levels down to very good levels,&#8221; he said.<\/p>\n<p>The study specifically looks to the banning of POPs in the 1970\u2019s to explain the reduction in pesticides found in breast milk. Chemicals such as organochlorine pesticides, organophosphate pesticides, pyrethroids and carbamate pesticide were classified as persistent organic pollutants because they remain for long periods of time in the environment, eventually making their way up food chains, accumulating in the fatty tissues and animals and humans.

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\/19269","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=19269"}],"version-history":[{"count":3,"href":"https:\/\/beyondpesticides.org\/dailynewsblog\/wp-json\/wp\/v2\/posts\/19269\/revisions"}],"predecessor-version":[{"id":19272,"href":"https:\/\/beyondpesticides.org\/dailynewsblog\/wp-json\/wp\/v2\/posts\/19269\/revisions\/19272"}],"wp:attachment":[{"href":"https:\/\/beyondpesticides.org\/dailynewsblog\/wp-json\/wp\/v2\/media?parent=19269"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/beyondpesticides.org\/dailynewsblog\/wp-json\/wp\/v2\/categories?post=19269"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/beyondpesticides.org\/dailynewsblog\/wp-json\/wp\/v2\/tags?post=19269"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
