Neonic Pesticide May Become More Toxic in Tap Water

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.

Relationship between Urinary N-Desmethyl-Acetamiprid and Typical Symptoms including Neurological Findings

We previously determined a metabolite of acetamiprid, N-desmethyl-acetamiprid in the urine of a patient, who exhibited some typical symptoms including neurological findings. We sought to investigate the association between urinary N-desmethyl-acetamiprid and the symptoms by a prevalence case-control study. Spot urine samples were collected from 35 symptomatic patients of unknown origin and 50 non-symptomatic volunteers (non-symptomatic group, NSG, 4–87 year-old).

Associations between Autism Spectrum Disorders and Maternally-Reported Use of Imidacloprid

The environmental contribution to autism spectrum disorders (ASD) is largely unknown, but household pesticides are receiving increased attention. We examined associations between ASD and maternally-reported use of imidacloprid, a common flea and tick treatment for pets. Our analytic dataset included complete information for 262 typically developing controls and 407 children with ASD. Compared with exposure among controls, the odds of prenatal imidacloprid exposure among children with ASD were slightly higher, with an odds ratio (OR) of 1.3 (95% Credible Interval [CrI] 0.78, 2.2).

Low levels of neonicotinoids are present in commonly-consumed fruits and vegetables sold in the US

Residue data for seven neonicotinoid pesticides collected between 1999 and 2015 by the US Department of Agriculture’s Pesticide Data Program (PDP) were collated and summarized by year across various food commodities, including fruit, vegetable, meat, dairy, grain, honey, and baby food, as well as water to qualitatively describe and examine trends in contamination frequency and residue concentrations. The highest detection frequencies (DFs) for neonicotinoids by year on all commodities were generally below 20%.

Truths about pesticides

Chemical agriculture is destroying the ecosystems that sustain all life. Pesticides are a key culprit in the decline of bees, butterflies and other pollinators — leading some scientists to warn of a “second silent spring.” , Pesticides wreak havoc on the soil by killing the organisms that are the basis of soil life. And they pollute rivers, lakes and oceans, leading to fish die-offs.

Organic food may reduce your risk of cancer

To reduce your risk of cancer, you know you should quit smoking, exercise regularly, wear sunscreen, and take advantage of screening tests. New research suggests another item might be added to this list: Choose organic foods over conventional ones. A study of nearly 70,000 French adults who were tracked for an average of 4.5 years found that those who ate the most organic foods were less likely to develop certain kinds of cancer than the people who ate the least.

Der Konsum von biologischen Lebensmitteln steht mit einem geringeren Risiko für Krebs in Verbindung

Eine neue Studie der angesehensten französischen medizinischen und landwirtschaftlichen Forschungsinstitutionen fand unter Leitung der Universität Sorbonne in Paris, Frankreich, heraus, dass der Konsum von biologischen Lebensmitteln mit einem geringeren Risiko für Krebs in Verbindung steht. Joanna Lewis, Leiterin für Politik bei der Soil Association, sagte: „Diese Studie meint, dass in der Krebsprävention größere Aufmerksamkeit darauf verwendet werden sollte, biologische Lebensmittel weitverbreiteter verfügbar zu machen, damit die Belastung durch Pestizide verringert wird.“

Exposure to imidacloprid during early development induces long-lasting changes in behavior and brain function in mice

We assessed the effects of the neonicotinoid imidacloprid (IMI) in adult male and female mice after in utero and early postnatal exposure. Pregnant mice were infused with IMI (0.5 mg/kg/day) from gestational day 4 to the end of nursing at postnatal day 21. The young adult offspring were studied in a series of biochemical and behavioral tests. To assess reproducibility, the behavioral analyses were conducted in three separate studies using multiple exposed litters. Exposure to IMI reduced fecundity, and in adult offspring, decreased body weight in male but not female pups.

Chlorpyrifos: Zulassungsstudie verschwieg offenbar potenzielle Gesundheitsgefahren

Umstrittenes Pestizid: Bei der Zulassung des umstrittenen Pflanzenschutzmittels Chlorpyrifos sind offenbar gravierende Fehler passiert. Denn wie sich nun herausstellt, haben die Behörden für ihr Bewertungsverfahren eine fragwürdige Studie akzeptiert. Die von der Industrie finanzierte Untersuchung wies bei dem Mittel demnach deutliche Effekte auf die Gehirnentwicklung von ungeborenen Ratten nach - verschwieg dieses Ergebnis jedoch. Dies stellt nach Ansicht der Forscher nun die grundsätzliche Sicherheit des europäischen Zulassungsverfahrens in Frage.
