UK Rivers Contaminated with Neonicotinoids; EU Delays Decision to Extend Ban
(Beyond Pesticides, December 14, 2017) Tests of waterways in the United Kingdom (UK) reveal rivers contaminated with
neonicotinoids, the class of chemicals highly toxic to bees and aquatic invertebrates. And now, although neonicotinoids were banned from use on certain crops in the European Union (EU) in 2013, an EU vote to extend the ban has been delayed.
The test results raise concerns over neonicotinoids’ impacts on waterways, especially to fish and birds. Under a new EU mandate -Water Framework Directive ‘Watch List’ initiative – the UK was required to monitor for all five commonly used neonicotinoids: imidacloprid, clothianidin, thiamethoxam, acetamiprid and thiacloprid. Twenty-three sites were sampled in 2016, 16 in England, four in Scotland, three in Wales and three in Northern Ireland.
This is the first systematic testing of neonicotinoids in rivers in Britain. According to the results, half the rivers tested in England had either chronic or acute levels of contamination. Of the 23 rivers tested across Britain, all but six contain neonicotinoids. Eight rivers in England exceed recommended chronic pollution limits, and two are acutely polluted.
Neonicotinoids are not only highly toxic to bees but also highly toxic to aquatic insects, which are a vital food source to fish and birds. In its recently released 2017 Preliminary Aquatic Risk Assessment for Imidacloprid, the U.S. Environmental Protection Agency (EPA) finds that aquatic invertebrates, especially keystone aquatic insects like the mayfly – basic to aquatic food chains, are sensitive to imidacloprid. Further, current imidacloprid levels detected in streams, rivers, lakes, and drainage canals exceed acute and chronic toxicity endpoints. Impacts occur at low concentrations and can result in decreased species abundance, altered predator-prey relationships, and reduced nutrient cycling.
According to the environmental group, BugLife, which reported on the UK results, the River Waveney on the Norfolk/Suffolk border is the most polluted river, with the acute harm level exceeded for a whole month, and the River Wensum in Norfolk, an area identified for special conservation, is also chronically polluted. Waveney and Wensum rivers, both containing residues of clothianidin and thiamethoxam, supply the Broads, an internationally important wetland site and home to many endangered aquatic animals. They note that nearby sugar beet fields are the most likely source of neonicotinoid contamination. Rivers near urban areas have higher levels of imidacloprid. No official limits exist in the EU for neonicotinoids in freshwater.
The European Commission met December 12 and 13, 2017 to decide on a proposal to extend the 2013 neonicotinoid ban to all outdoor crops, but this decision was delayed. The Standing Committee on Plants, Animals, Food and Feed discussed proposals for an expanded ban, but no vote was taken. The issue is expected to be on the agenda again in early 2018. The UK government has reversed its previous stance on neonicotinoids, now saying that it should be banned due to their harm to pollinators.
After its recent aquatic analysis, EPA quietly adjusted its aquatic benchmarks for imidacloprid to 0.385 ug/L for acute risks (down from 34.5ug/L) and 0.01 ug/L for chronic risks (down from 1.05 ug/L), reflecting the high toxicity of imidacloprid to aquatic invertebrates. Independent studies have shown impacts to aquatic life occurring at levels as low as 0.65 ug/L for acute toxicity and 0.03 ug/L for chronic toxicity.
Earlier this year, Beyond Pesticides released Poisoned Waterways, a report which documents the persistence of neonicotinoids in U.S. waterbodies and the danger they cause to aquatic organisms, resulting in complex cascading impacts on the aquatic food web. The report also highlights current regulatory failures of EPA aquatic standards, which continue to underestimate risks to sensitive species due to a reliance on test protocols that do not reflect real-world exposures or susceptibilities.

The move comes as more and more states enact or consider restrictions on use of the herbicide, which is intended to be paired with genetically engineered (GE) soybean seeds resistant to both dicamba and another controversial herbicide produced by Monsanto, glyphosate.

The groups claim that the German regulatory authority, the Federal Institute for Risk Assessment (BfR), and the European Food Safety Authority (EFSA) used material directly from Monsanto in their report over the safety of glyphosate without making clear that the data came from Monsanto itself.  “Both the BfR and the EFSA were in breach of the requirement obliging them to make an independent, objective and transparent assessment,†the groups said in a statement
(Beyond Pesticides, December 5, 2017) Fungicides are likely playing an important role in the decline of North American bumblebee populations, according to new research published by a team at Cornell University. While overwhelming data continue to indicate that insecticides, particularly the neonicotinoid class of chemicals, are the leading factor in overall pollinator declines, Cornell scientists discovered that fungicides, in particular the chemical chlorothalonil, are likely compounding risk and toxicity for U.S. bumblebee species. As new studies continue to expand the chemical culprits in pollinator declines, calls for a wholesale change in agricultural practices toward more sustainable organic production are reinforced.

(Beyond Pesticides, December 1, 2017) Ichneumonid wasps (family Ichneumonidae), are a widely distributed parasitoid wasp family within the order Hymenoptera. The name “ichneumonid†comes from Greek words meaning “tracker†and “footprint.†And females do indeed hunt for suitable “hosts†by first identifying the organism’s food source. Once a suitable host is found, females deposit eggs onto the unsuspecting insect larvae where, within ten days to several weeks, the Ichneumonid larva kills the host by feeding on its body fluids before it emerges. They are also known as “scorpion wasps†for the extreme length and curving motion of their segmented abdomens. Note: both adult males and females are stingless, and feed on nectar.
both contain the active ingredient, sulfoxaflor, which is highly toxic to bees. The ruling overturned the decision by France’s health and environment agency, ANSES, to allow the use of the sulfoxaflor products. Sulfoxaflor use was also challenged in the U.S. by beekeepers concerned about its impact on already declining bee populations.

The turkey, potatoes, stuffing, and cider all originated in fields far from our homes, and those working in those fields deserve our thanks. They deserve our thanks because many of these workers work long hours, under deplorable conditions, and are exposed to pesticides that put their health and that of their families at risk. So, as we enjoy our pumpkin pie, cranberry sauce, and apple crumble, remember all the hardworking farmworkers who have helped to bring our meal to the Thanksgiving table. At the same time, we give thanks for the environment that is so plentiful and nurturing of life, and remember the importance of pollinators and biodiversity in sustaining life.

Member states voted last week, but failed to approve, continued use even after months of deliberation over the controversial herbicide. Glyphosate (Roundup) is also up for review in the U.S., but many expect the herbicide to be reregistered by the U.S. Environmental Protection Agency (EPA), despite health concerns.
damage, the Arkansas State Plant Board (ASPB) voted earlier this week to prohibit the use of the weedkiller in agriculture during the next growing season. If officially approved by a subcommittee of the state legislature, the new regulations will make dicamba applications between April 16 and October 31, 2018, illegal for Arkansas farmers. The move by the State Plant Board is a huge blow to multinational agrichemical companies Monsanto and BASF, both of which have developed genetically engineered (GE) soybean crops tolerant of dicamba herbicides.
