However, PFBC biologists continue to find sores and lesions on young-of-year bass during late spring and early summer surveys at alarming rates.<\/p>\n<p>The PFBC first documented disease-related mortality of young-of-year SMB in the Susquehanna River in 2005. The continued mortality has contributed to the decline in abundance of SMB. Since 2012, the PFBC has unsuccessfully petitioned the state Department of Environmental Protection (DEP) to add the river to the state\u2019s bi-annual list of impaired waterways.<\/p>\n<p>\u201cThe impairment designation is critical because it starts a timeline for developing a restoration plan,\u201d said Mr. Arway. \u201cWe\u2019ve known the river has been sick since 2005, when we first started seeing lesions on the smallmouth. Now we have more evidence to further the case for impairment.\u201d<\/p>\n<p>Last summer, <a href=\"http:\/\/link.springer.com\/article\/10.1007\/s10661-014-3868-5\">research by the U.S. Geological Survey (USGS) <\/a>showed a strong correlation between the occurrence of intersex characteristics on fish and areas of high agricultural use in Pennsylvania. Three species of fish were examined in three separate watersheds in the state to assess whether characteristics caused by hormones and hormone-mimicking compounds, such as immature eggs in male fish, were present. In aquatic environments, the presence of these intersex characteristics is widely used as a biomarker for assessing exposure to estrogenic chemicals, as well as anti-androgenic chemicals which inhibit development of male characteristics. Male smallmouth bass from all sites sampled had immature eggs in their testes; however, SMB in the Susquehanna drainage had a significantly higher prevalence and severity of these effects than sites in the Ohio drainage. When compared against the percentage of agricultural land use, which is higher in the Susquehanna, a link was established.<\/p>\n<p>Fish and other aquatic organisms face numerous risks from pesticide exposures, even at low levels. In fact, USGS scientists identified pesticides as one of the contaminants in the Potomac River linked to \u00a0<a href=\"https:\/\/www.beyondpesticides.org\/dailynewsblog\/?p=311\">intersex-fish<\/a> \u00a0observed there. \u00a0<a href=\"https:\/\/www.beyondpesticides.org\/gateway\/pesticide\/atrazine.htm\">Atrazine<\/a>, one of the most commonly used herbicides in the world, has been shown to affect reproduction of fish at concentrations below U.S. Environmental Protection Agency\u2019s (EPA) water-quality guidelines. Concentrations of atrazine commonly found in agricultural streams and rivers have been associated with \u00a0<a href=\"https:\/\/www.beyondpesticides.org\/dailynewsblog\/?p=3675\">a reduction in reproduction and spawning<\/a>, as well as tissue abnormalities.<\/p>\n<p>In fish and humans, <a href=\"https:\/\/www.beyondpesticides.org\/health\/endocrine.php\">endocrine disrupting effects<\/a> include direct effects on traditional endocrine glands, their hormones and receptors, such as estrogens, anti-androgens, and thyroid hormones, as well as signaling cascades that affect many of the body\u2019s systems, including reproductive function and fetal development, the nervous system and behavior, the immune and metabolic systems, the liver, bones and many other organs, glands and tissues. Hundreds of <a href=\"https:\/\/www.beyondpesticides.org\/dailynewsblog\/index.php?s=low+dose\">scientific articles<\/a> have been published across the globe demonstrating how a broad selection of chemicals can interfere with the normal development at all ranges of exposure. Scientists discovered effects for some widely used chemicals at concentrations thousands of times less than federal \u201csafe\u201d levels of exposure derived through traditional toxicological tests. Whatever the exposure level, neither fish nor human are protected from most endocrine-disrupting chemicals present in our waterways.<\/p>\n<p>\u201cIf we do not act to address the water quality issues in the Susquehanna River, Pennsylvania risks losing what is left of what was once considered a world-class smallmouth bass fishery,\u201d Mr. \u00a0Arway \u00a0said. \u201cDEP is expected to release its 2016 list of impaired waters in late fall. We are urging them once again to follow the science and add the Susquehanna River to the list.\u201d<\/p>\n<p>PFBC biologists conduct annual young-of-year and adult SMB surveys on this stretch of the river from late June through the end of October when sampling conditions are appropriate. In addition, PFBC has enlisted the assistance of certain anglers and guides to provide fish with obvious masses or lesions if they encounter any when fishing the river.<\/p>\n<p>PFBC staff are continuing to work with DEP, FWS, USGS, the U.S. Environmental Protection Agency and other partners to focus efforts on better understanding what factors are impacting the SMB inhabiting the middle Susquehanna and lower Juniata rivers. In the meantime, catch-and-release regulations for SMB are already in place on 98 miles of the middle portion of the Susquehanna River where the symptomatic fish was captured and on the lower 31.7 miles of the Juniata River from Port Royal to the mouth.<\/p>\n<p>Beyond Pesticides continues to fight to \u00a0prevent water pollution and harmful agricultural practices.

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\/15593","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=15593"}],"version-history":[{"count":7,"href":"https:\/\/beyondpesticides.org\/dailynewsblog\/wp-json\/wp\/v2\/posts\/15593\/revisions"}],"predecessor-version":[{"id":15600,"href":"https:\/\/beyondpesticides.org\/dailynewsblog\/wp-json\/wp\/v2\/posts\/15593\/revisions\/15600"}],"wp:attachment":[{"href":"https:\/\/beyondpesticides.org\/dailynewsblog\/wp-json\/wp\/v2\/media?parent=15593"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/beyondpesticides.org\/dailynewsblog\/wp-json\/wp\/v2\/categories?post=15593"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/beyondpesticides.org\/dailynewsblog\/wp-json\/wp\/v2\/tags?post=15593"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
