Glyphosate Causes Liver Disease?

A new cutting edge study from Kings College, London has found that residues of popular weedkiller glyphosate found in food can cause fatty liver disease. This is another huge blow for glyphosate, but is it the final nail in the coffin?

Glyphosate is the world’s most widely sold weedkiller, commonly found in Monsanto’s Roundup, and we’re fighting to ban it as a pre-harvest treatment. Glyphosate is sprayed on our wheat and other cereals just before harvest – mainly to allow machines to go a little faster. From there it follows the grain into our bread; recent testing by the Defra Committee on Pesticide Residues in Food (PRiF) found that almost two thirds of wholemeal bread sampled contained glyphosate. Supermarkets and bread manufacturers say this is quite OK as Roundup is usually below official safety levels.

However, this new peer-reviewed study, led by Dr Michael Antoniou at King’s College London, has found that weedkillers like Roundup cause non-alcoholic fatty liver disease at very low doses, thousands of times below levels permitted by regulators worldwide. This research is the first evidence of a clear causative link between consumption of Roundup – at levels that are found in the real world – and a serious disease. It follows previous findings from the World Health Organisation’s International Agency for Research on Cancer, who concluded that glyphosate is a ‘probable carcinogen’.

It is extraordinary that glyphosate, in use for decades, has only now been recognised as a cause of the liver disease NAFLD (non-alcoholic fatty liver disease), which can cause fatigue, weakness, weight loss, loss of appetite, nausea, abdominal pain, spider-like blood vessels, yellowing of the skin and eyes (jaundice), itching, fluid build-up and swelling of the legs and abdomen, and mental confusion.

The study was conducted over two years, where rats were administered a very low daily dose of four nanograms per kilogram of bodyweight per day. To put that into perspective that is 75,000 times below the levels of glyphosate permitted by the EU in our food. According to lead researcher Dr Michael Antoniou, previous studies on human urine found that we often consume around a thousand times the amount of glyphosate the rats consumed. Regulators globally accept toxicity studies in rats as indicators of human health risk, making this a significant, and truly disturbing, discovery.

The news about Roundup comes just as France announces an official ban on the use of all harmful chemicals in outdoor places where young children, crucial pollinators and the general public frequently gather – the ban covers all public parks, gardens and forests including famed Parisian green spaces like Jardin des Tuileries, Bois de Vincennes and Jardin de Luxembourg. Only French cemeteries and sports stadiums are exempt. In 2019, the law will be extended to private gardens. These national moves follow cities like Lyon, France’s third-largest, and Strasbourg, which have kept all their public parks and gardens (300 in Lyon alone) pesticide-free since 2008.

We need to get this poisonous weedkiller out of our bread, and out of our bodies. We are calling for an end to spraying Glyphosate on crops just before they are harvested, and you can join the fight by joining us or writing to your local MP. This new study raises serious concerns for human health and must be taken seriously by Monsanto and the government; with enough pressure we can ensure it is the final nail in the coffin for glyphosate.

Pesticide Manufacturers Own Tests Reveal Serious Harm To Honeybees 

Unpublished field trials by pesticide manufacturers show their products cause serious harm to honeybees at high levels, leading to calls from senior scientists for the companies to end the secrecy which cloaks much of their research.
The research, conducted by Syngenta and Bayer on their neonicotinoid insecticides, were submitted to the US Environmental Protection Agency and obtained by Greenpeace after a freedom of information request.
Neonicotinoids are the world’s most widely used insecticides and there is clear scientific evidence that they harm bees at the levels found in fields, though only a little to date showing the pesticides harm the overall performance of colonies. Neonicotinoids were banned from use on flowering crops in the EU in 2013, despite UK opposition.
Bees and other insects are vital for pollinating three-quarters of the world’s food crops but have been in significant decline, due to the loss of flower-rich habitats, disease and the use of pesticides.
The newly revealed studies show Syngenta’s thiamethoxam and Bayer’s clothianidin seriously harmed colonies at high doses, but did not find significant effects below concentrations of 50 parts per billion (ppb) and 40ppb respectively. Such levels can sometimes be found in fields but concentrations are usually below 10ppb.

World Health Organisation Says Most Common Weedkiller ‘Probably’ Causes Cancer

Roundup_cancer

In March, 2015, 17 experts from 11 countries met at the International Agency for Research on Cancer (IARC; Lyon, France) to assess the carcinogenicity of the organophosphate pesticides tetrachlorvinphos, parathion, malathion, diazinon, and glyphosate (table). These assessments will be published as volume 112 of the IARC Monographs.

Glyphosate is a broad-spectrum herbicide, currently with the highest production volumes of all herbicides. It is used in more than 750 different products for agriculture, forestry, urban, and home applications. Its use has increased sharply with the development of genetically modified glyphosate-resistant crop varieties. Glyphosate has been detected in air during spraying, in water, and in food. There was limited evidence in humans for the carcinogenicity of glyphosate. Case-control studies of occupational exposure in the USA, Canada and Sweden reported increased risks for non-Hodgkin lymphoma that persisted after adjustment for other pesticides. The AHS cohort did not show a significantly increased risk of non-Hodgkin lymphoma. In male CD-1 mice, glyphosate induced a positive trend in the incidence of a rare tumour, renal tubule carcinoma. A second study reported a positive trend for haemangiosarcoma in male mice. Glyphosate increased pancreatic islet-cell adenoma in male rats in two studies. A glyphosate formulation promoted skin tumours in an initiation-promotion study in mice.

Glyphosate has been detected in the blood and urine of agricultural workers, indicating absorption. Soil microbes degrade glyphosate to aminomethylphosphoric acid (AMPA). Blood AMPA detection after poisonings suggests intestinal microbial metabolism in humans. Glyphosate and glyphosate formulations induced DNA and chromosomal damage in mammals, and in human and animal cells in vitro. One study reported increases in blood markers of chromosomal damage (micronuclei) in residents of several communities after spraying of glyphosate formulations. Bacterial mutagenesis tests were negative. Glyphosate, glyphosate formulations, and AMPA induced oxidative stress in rodents and in vitro. The Working Group classified glyphosate as “probably carcinogenic to humans” (Group 2A).

2,4-D Herbicide Deadly To Earthworms In Laboratory Tests

worm_measure

Laboratory tests were conducted to compare the effects of various concentrations of glyphosate and 2,4-D on earthworms (Eisenia foetida) cultured in Argissol during 56 days of incubation. The effects on earthworm growth, survival, and reproduction rates were verified for different exposure times. Earthworms kept in glyphosate-treated soil were classified as alive in all evaluations, but showed gradual and significant reduction in mean weight (50%) at all test concentrations. For 2,4-D, 100% mortality was observed in soil treated with 500 and 1,000 mg/kg. At 14 days, 30%-40% mortality levels were observed in all other concentrations. No cocoons or juveniles were found in soil treated with either herbicide. Glyphosate and 2,4-D demonstrated severe effects on the development and reproduction of Eisenia foetida in laboratory tests in the range of test concentrations.

Glyphosate Affects Interactions Between Earthworms And Mycorrhizal Fungi

Hyphae

Herbicides containing glyphosate are widely used in agriculture and private gardens, however, surprisingly little is known on potential side effects on non-target soil organisms. In a greenhouse experiment with white clover we investigated, to what extent a globally-used glyphosate herbicide affects interactions between essential soil organisms such as earthworms and arbuscular mycorrhizal fungi (AMF). We found that herbicides significantly decreased root mycorrhization, soil AMF spore biomass, vesicles and propagules. Herbicide application and earthworms increased soil hyphal biomass and tended to reduce soil water infiltration after a simulated heavy rainfall. Herbicide application in interaction with AMF led to slightly heavier but less active earthworms. Leaching of glyphosate after a simulated rainfall was substantial and altered by earthworms and AMF. These sizeable changes provide impetus for more general attention to side-effects of glyphosate-based herbicides on key soil organisms and their associated ecosystem services.

Glyphosate Sublethal Effects On The Population Dynamics Of The Earthworm

earthworm_running
Pesticides’ sublethal effects are not regularly taken into account when assessing agrochemical’s toxicity. With the objective of detecting chronic, sublethal effects of the widely used herbicide glyphosate, an experiment was performed using the earthworm Eisenia fetida as model organism. Earthworm adults were randomly assigned to three glyphosate treatments: control (no glyphosate), regular dose for perennial weeds, and double dose. Six E. fetida individuals were placed in each pot. Two random pots were taken weekly from each treatment and the number of adults, individual weight, number of cocoons, and presence and number of young earthworms were recorded. A matrix analysis was performed with the data. The matrix population model built showed that while the control population had a positive growth rate, both glyphosate treatments showed negative growth rates. The results suggest that under these sublethal effects, non-target populations are at risk of local extinction, underscoring the importance of this type of studies in agrochemical environmental risk assessment.

Non-target organisms can be at risk of local extinction due to agrochemicals chronic sublethal effects, which are not consistently taken into account in toxicity and risk assessment studies.

Health Costs Of Hormone Disrupting Chemicals Over €150bn A Year In Europe

plastic-health-risk

Lower IQ, adult obesity and 5% of autism cases are all linked to exposure to endocrine disruptors found in food containers, plastics, furniture, toys, carpeting and cosmetics, says new expert study

Scientists recommend against pregnant women and children using plastic containers for food, especially in the microwave due to endocrine disruptors.

Europe is experiencing an explosion in health costs caused by endocrine-disrupting chemicals (EDCs) that is comparable to the cost of lead and mercury poisoning, according to the most comprehensive study of the subject yet published.

Endocrine disruptors are chemicals that interfere with the human hormone system, and can be found in food containers, plastics, furniture, toys, carpeting and cosmetics.

The new series of reports by 18 of the world’s foremost experts on endocrine science pegs the health costs of exposure to them at between €157bn-€270bn (£113bn-£195bn), or at least 1.23% of the continent’s GDP.

“The shocking thing is that the major component of that cost is related to the loss of brain function in the next generation,” one of the report’s authors, Professor Philippe Grandjean of Harvard University, told the Guardian.

“Our brains need particular hormones to develop normally – the thyroid hormone and sex hormones like testosterone and oestrogen. They’re very important in pregnancy and a child can very well be mentally retarded because of a lack of iodine and the thyroid hormone caused by chemical exposure.”

After IQ loss, adult obesity linked to exposure to phthalates, a group of chemicals used in plastics, was the second largest part of the overall cost, with an estimated price tag of €15.6bn a year, according to the paper, which was published on Thursday in the Endocrine Society’s Journal of Clinical Endocrinology and Metabolism.

The study attributes at least 5% of European autism cases to EDC exposure, but Grandjean said the figure likely under-estimated the linkage, because of difficulties in measuring foetal exposure to chemicals after a child had been born.

“I would recommend that pregnant women and children eat organic fruits and vegetables and avoid using plastic containers and canned food, especially in the microwave, because containers are usually treated on the inside with substances and compounds that can leak into the tomato soup and may act as endocrine disruptors,” he said.
