Insecticiden

Researchers in California just demonstrated that a mere six days of eating all organic is enough to significantly reduce levels of harmful pesticides in your body. In the study, four families (with completely different backgrounds) consumed conventional products for six days and had their urine tested. Then, they ate a 100 percent organic diet for six days and had their urine tested again. The drop in pesticide levels present in their urine between tests was massive.

There has been a recent investigation here on Bellingcat, of a poisoning incident in Bulgaria in April 2015, where an individual named Emilian Gebrev was posioned. An angle of this investigation has been to see if it is at all connected to the attempted murder of Sergei Skripal. One particular aspect of recent publicity has been to examine whether or not a “Novichok” series nerve agent was responsible for the 2015 poisoning incident.

A new peer-reviewed study shows that eating a completely organic diet—even for just one week—can dramatically reduce the presence of pesticide levels in people, a finding that was characterized as “groundbreaking” by critics of an industrial food system that relies heavily on synthetic toxins and chemicals to grow crops and raise livestock. Published in the Environmental Research, the study—titled Organic Diet Intervention Significantly Reduces Urinary Pesticide Levels in U.S.

An Ultra performance liquid chromatography (UPLC) coupled to UV detection method was developed to determine acetamiprid residues in water reservoirs of northern Benin, close to cotton fields. The quantification limit of this method was 0.2 µg L−1 acetamiprid in water, its precision ranged between 8% and 22%, and its trueness between 99% and 117% (for concentrations ranging from 0.2 to 5.0 µg L−1). Acetamiprid residues were determined in water samples collected in four reservoirs from northern Benin during the phytosanitary treatment period of cotton.

Imidacloprid is a widely used insecticide with high runoff potential posing a significant threat to aquatic ecosystems. In order to determine the spatial and temporal concentrations of imidacloprid in Forester Creek, a tributary to the San Diego River, surface water samples were collected from two sites under wet-weather and dry-weather conditions. Imidacloprid was detected with 100% frequency in surface water samples from Forester Creek with a median concentration of 16.9 ng/L (range: 3.8–96.8 ng/L). Over 60% of samples exceeded U.S. EPA's chronic exposure benchmark (10 ng/L).

The nature of receptor binding by imidacloprid is of fundamental importance for risk assessment. If, as Bayer and Syngenta-sponsored scientists now infer, receptor binding is reversible, the toxicity of imidacloprid would be concentration-dependent only, and there would likely be a threshold

Yet again, our government scientists—the oft neglected but so important brain trust of our Nation—bring the public some very important new data. Pesticide water monitoring experts at the U.S. Geological Survey (USGS) paired up with scientists from the University of Iowa in a federally-funded collaboration to track neonicotinoid pesticides or “neonics” in tap water, including the potential to form chlorinated disinfection byproducts (DBPs) from the pesticides and their metabolites that may be more toxic than the original compounds. And, the news isn’t good.

Der Bestand an Brutvögeln im landwirtschaftlichen Raum ist in Europa während der vergangenen Jahrzehnte um mehr als die Hälfte zurückgegangen. Der Hauptgrund ist die intensive Landwirtschaft. Seit 1980 ist der Bestand an Vögeln des Kulturlands in der EU um rund 56 Prozent eingebrochen. Zu den betroffenen Arten gehören beispielsweise Feldlerche, Star (Sturnus vulgaris) oder Kiebitz (Vanellus vanellus). Das geht aus den gesammelten Daten des European Bird Census Council hervor, einem Zusammenschluss europäischer Vogelexperten mit Sitz im niederländischen Nijmegen.
