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).
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%.
Occurrence and distribution of five neonicotinoids (NEOs) in surface water and sediment were studied in the Pearl Rivers, including three trunk streams, Dongjiang, Beijiang, Xijiang River (DR, BR and XR), South China. At least one neonicotinoid was detected in surface water and sediment of the Pearl Rivers, with imidacloprid (IMI) and thiamethoxam (THM) being the frequently detected NEOs. Total amount of NEOs (∑5neonics) in surface water and sediment ranged from 24.0 to 322 ng/L, and from 0.11 to 11.6 ng/g dw, respectively.
Millions of birds have been lost from New Zealand countryside over the past 30 years. Most of them were introduced birds so have not been missed, but surely someone should have recognised that their loss indicated something had gone very wrong with farmland ecosystems. It is the decline of insects that has had the greatest impact on birds. There is no monitoring of insects in New Zealand to my knowledge.
In Michigan, half of its bumblebee species have declined by 50 percent or more, Michigan Radio reported. "Of those twelve species, about half of them have declined and the other half are stable," Thomas Wood, a post-doctoral research associate at Michigan State University, told the radio station. Of the six species that have declined, their numbers dropped by more than 50 percent, Wood added. One species, the rusty patched bumblebee (Bombus affinis), has even gone extinct in Michigan. In 2017, the U.S.
Today, 2,000 pesticides with 500 chemical substances are being used in Europe. However, data on how such substances affect soil quality is incomplete and fragmented, and fails to clearly reflect their overall impact on soil systems and human health. First-time research conducted in the course of two EU-funded projects, iSQAPER and RECARE, is shedding light on the state of European soils. The results are far from reassuring.
Western monarch butterflies spend the winter in more than 300 forested groves along the California coast, including large populations in Riverside and Los Angeles counties, Pacific Grove, Monterey and at Natural Bridges State Beach in Santa Cruz. They can normally be seen from November to March. With the number of butterflies declining rapidly, here are four things governments and the public can do to help:
Protect and manage California overwintering sites.
Twelve pesticides made with chemicals shown to harm bees and other pollinators are slated to be banned as part of a proposed settlement with the manufacturers, the EPA announced Dec. 12. The pesticides, marketed by Syngenta AG., Bayer AG, and Valent USA Corp., contain either thiamethoxam or clothianidin, two chemicals in the neonicotinoid class that are linked to declining bee populations.
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.
