It can disrupt the lives of freshwater invertebrates and their communities, upsetting the balance and functioning of entire freshwater ecosystems. This is shown by ecologist Henrik Barmentlo and colleagues in their article <a rel=\"nofollow\" target=\"_blank\" href=\"https:\/\/onlinelibrary.wiley.com\/doi\/10.1111\/ele.70121\" target=\"_blank\">published<\/a> in <i>Ecology Letters<\/i>.<\/p>\n<p>In an earlier study, Henrik Barmentlo and his fellow researchers of the Living Lab in Leiden linked this pesticide to extreme declines in insects. In the experimental ditches of the Living Lab, they saw that insects such as dragonflies and beetles drastically declined both in abundance as well as biomass. Now they show that not only insects, but even whole communities are affected at concentrations that were deemed safe for aquatic life.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Environmental_norms_do_not_protect_aquatic_life\"><\/span>Environmental norms do not protect aquatic life<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>&#8220;Our test concentrations included the environmental norms set by EFSA and the EPA at which aquatic life should be protected, this turned out not to be the case,&#8221; says Barmentlo, ecologist at the Institute of Environmental <a href=\"https:\/\/buradabiliyorum.com\/en\/category\/sciencee\/\" data-internallinksmanager029f6b8e52c=\"5\" title=\"Science\" target=\"_blank\" rel=\"noopener\">Science<\/a>.<\/p>\n<p>To come to these conclusions, the authors exposed 27 experimental ditches to a concentration of thiacloprid (versus 9 control ditches). Thiacloprid belongs to the group of &#8220;neonicotinoid&#8221; insecticides which are meant to target &#8220;pest&#8221; insects such as aphids and fleas. They then measured many parameters in the ecosystems.<\/p>\n<p>&#8220;We measured invertebrate diversity, plants, phytoplankton, floating algal beds, decomposition and invertebrate consumption and various other water quality parameters,&#8221; says Barmentlo.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Thick_mats_of_floating_algae\"><\/span>Thick mats of floating algae<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>&#8220;Our ecosystems were in a perilous state after exposure to the pesticide,&#8221; Barmentlo says. Invertebrate consumption and phytoplankton abundances declined strongly, while the ditches became covered with thick mats of floating algae that blocked sunlight. Even months after the experiment, the researchers still observed these algal beds covering the ditches.<\/p>\n<p>Although the European Union restricted the use of thiacloprid in 2020, emergency exemptions still allow the use of neonicotinoids in certain cases, meaning the threat to freshwater ecosystems persists. Moreover, in most parts of the world neonicotinoids are still widely used.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Stricter_regulations_needed\"><\/span>Stricter regulations needed<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>The authors advocate for stricter regulations on neonicotinoids and improved monitoring methods like the <a href=\"https:\/\/buradabiliyorum.com\/en\/category\/download-scripts-themes-apps\/\" data-internallinksmanager029f6b8e52c=\"9\" title=\"Download Scripts &amp; Themes &amp; Apps\" target=\"_blank\" rel=\"noopener\">app<\/a>lied network models to detect damage to species communities. Barmentlo says, &#8220;By refining how we assess environmental threats using new techniques at the ecosystem level, we can make more informed decisions to protect biodiversity, water quality, and the overall health of our ecosystems.&#8221;<\/p>\n<div class=\"article-main__more p-4\">\n<p><strong>More information:<\/strong><br \/>\n\t\t\t\t\t\t\t\t\t\t\t\tHenrik S.
