  1. Environmental #pesticide exposure and the risk of irritable bowel syndrome: A case-control study

    Environmental Toxicology and Pharmacology
    Volume 98, March 2023, 104076

    Highlights

    • The risk of irritable bowel syndrome is higher in areas of high pesticide exposure.
    • Agronomic criteria were used to categorize pesticide exposure in the study population.
    • A total of 18,807 cases of irritable bowel syndrome were studied.
    • Environmental pesticide exposure is linked to irritable bowel syndrome.

    Abstract
    The agricultural model in southern #Spain is highly productive, mainly due to the intensive cultivation under plastic. Despite strict pesticide regulation, human exposure to pesticides in the environment has been connected to an increase in diseases such as #CeliacDisease. Certain pesticides have also been associated to the disruption of the intestinal #microbiota, which has been xtied to the development of irritable bowel syndrome (IBS). A case-control study was conducted in Andalusia, south #Spain, to assess the prevalence and risk of IBS related to pesticide exposure. This research found a high prevalence of IBS in #Andalusia between 2000 and 2021 in areas with high pesticide exposure using agronomic criteria. Furthermore, the odds ratio for IBS was significantly higher in the population with high pesticide exposure. This study suggests that pesticides may be involved in IBS, whereas more research is needed to determine the role of pesticides in IBS symptomatology.

    Excerpts: "[In the locations of the study], the most commonly used insecticides are #organophosphates (primarily chlorpyrifos), N-methylcarbamates, macrocyclic lactones, #neonicotinoids, and pyrethroids. #Fungicides frequently used in plastic greenhouses include (di) thiocarbamates, conazoles, dicarboximide), anilino-pyrimidines, and copper salts. Bipyridyl (paraquat, diquat), organophosphonates (#glyphosate), chlorotriazine, and phenylurea are the herbicides most popularly used in the study areas (García-García et al., 2016)."

    Studies on Rats

    "A wide range of environmental pollutants, including heavy metals, insecticides, herbicides, and pesticides, can cause gut dysbiosis (Jin et al., 2015, Lin et al., 2020, Reygner et al., 2016). As suggested in our findings, there is also an increased risk of IBS precisely in pesticide-heavy areas and particularly in women. Previous research have found sexually dimorphic metabolic effect after pesticides exposures (Lukowicz et al., 2018). In this regard, #Roundup®, a glyphosate-based herbicide (#GBH) widely used in Andalusian crops, can increase the #Bacteroidetes group while decreasing the #Lactobacillaceae family in fecal samples of female rats (Lozano et al., 2018). Similarly, chronic glyphosate exposure reduces Corynebacterium, Firmicutes, Bacteroidetes, and Lactobacillus in mice following GBH administration (Aitbali et al., 2018). Exposure to fungicides such as imazalil can also alter the composition of the GM after acute and chronic administration. Specifically, in mice, imazalil increases the relative abundance of Firmicutes, Proteobacteria and Actinobacteria while decreasing the abundance of Bacteroidetes (Jin et al., 2016). Insecticides such as chlorpyrifos, diazinon and aldicarb also disrupt the GM of rats and mice (Aitbali et al., 2018, Gao et al., 2019, Gao et al., 2017, Joly et al., 2013). This modification has been associated with increased intestinal permeability and bacterial translocation in the case of chlorpyrifos (Condette et al., 2014). Diazinon inhibits several SCFA-producing genera in the Lachnospiraceae family, which operate as an energy substrate for colonic epithelial cells, altering energy harvesting in the intestinal epithelium (Gao et al., 2017)."

  5. Pesticide spray drift from intensive horticulture on the the mid-north coast NSW -
    Discontent in the region.

    Home owners, dairy and beef producers among those concerned about how pesticide use affects their land as well as water quality on the mid-north coast

    “Between 2001 and 2016 blueberry farming expanded 400% – mainly around the Coffs Harbour region.”

    “This monitoring showed the continued detection of pesticides in most waterways sampled, highlighting the need for ongoing monitoring in the region.”

    “Monitoring in the Nambucca valley by the EPA has detected three different pesticides in low levels in three creeks, suggesting water quality in the area is not being impacted by excessive amounts of pesticides.”

  7. Les néonics, c’est toxique pour la santé humaine, c’est pour ça qu’on les a interdits. Mais c’est toxique pour tous les autres êtres vivants, et pour les insectes en premier, pardi. TOUS les insectes, pas seulement les gentils pollinisateurs. L’effondrement de l’entomofaune, c’est le pire des flips sur la biodiversité.

    Et voilà qu’une proposition de loi (= initiative d’un parlementaire) voudrait réautoriser des néonics. Qu’en pense le gouvernement ? on sait pas.

    Alors, une lettre ouverte contre ce qui serait un terrible régression à été signée par 1200 médecins et scientifiques. Et elle contient des propositions pour du mieux, au contraire.

    Stéphane Foucart @sfoucart y consacre un article du Monde. Extrait.

    Réintroduire des produits « tueurs d’abeilles » interdits, placer le « gendarme » des pesticides sous la houlette des filières agricoles, maintenir l’évaluation des molécules sous la coupe de leurs fabricants, écarter la littérature scientifique de l’analyse des risques… Dans une lettre ouverte rendue publique lundi 5 mai, plus de 1 200 médecins et scientifiques alertent les ministres de l’agriculture, de la santé et de l’environnement sur les failles du système d’homologation de ces produits, qui font de la population des « cobayes », écrivent les signataires.

    Parmi eux, plusieurs centaines de médecins, mais aussi de nombreux membres des communautés scientifiques impliquées (toxicologie, écotoxicologie, agronomie, etc.) issus des universités et des organismes de recherche publics (CNRS, Inrae, IRD, Cirad).

    Les signataires demandent le renforcement de l’expertise réglementaire et s’opposent aux dispositions de la proposition de loi du sénateur de la Haute-Loire Laurent Duplomb (LR), qui doit être examinée par les députés avant la fin du mois de mai. « Cette proposition de loi contient de nombreuses mesures qui vont renforcer la dépendance des agriculteurs aux pesticides chimiques de synthèse, sans pour autant répondre à leur demande de rémunération juste, dénoncent les signataires. Or, cette dépendance pose déjà d’énormes problèmes de santé humaine et de dégradation de l’environnement. »

    Mais il y a d‘autres dispositions carrément WTF dans la PP Duplomp (dans l‘aile, on l’espère). Autre extrait :

    Ceux-ci s’en prennent aussi à la proposition de loi Duplomb, qui prévoit notamment la création d’un « conseil d’orientation pour la protection des cultures », composé de représentants des filières agricoles et de l’industrie des pesticides, qui superviserait l’agenda de travail de l’Agence nationale de sécurité sanitaire de l’alimentation, de l’environnement et du travail (Anses). Cela reviendrait, selon les 1 200 chercheurs et médecins signataires, « à une remise en cause de la place de l’expertise à travers un affaiblissement du rôle de l’Anses ». Auditionné à l’Assemblée nationale le 25 mars, le directeur général de l’Anses, Benoît Vallet, avait déclaré qu’une telle mise sous tutelle de l’agence reviendrait à une forme de rupture de contrat. « Pour moi, il n’y aurait plus la possibilité de rester directeur général de l’agence », avait-il précisé.

    « La loi Duplomb sacrifie la santé et en premier lieu celle des agriculteurs au profit de l’industrie agrochimique, et constitue une grave remise en cause de l’indépendance de la science, comme on le voit aux Etats-Unis », estime Marc Billaud, chercheur au CNRS, signataire du courrier aux ministres et coauteur – avec le professeur d’hématologie aux Hospices civils de Lyon et à l’université Lyon-I Pierre Sujobert – d’un article dénonçant les manœuvres d’occultation des liens entre pesticides et cancers du sang, dans la prochaine édition de la Revue de biologie médicale.

  8. Our meta-analysis on the impact of neonicotinoids on birds is out at Ecology Letters: onlinelibrary.wiley.com/doi/fu

    A massive effort by my co-authors putting together such a comprehensive dataset (1612 effect sizes from 49 studies). The results unfortunately show consistent negative effects of neonicotinoid exposure on bird health, behaviour, reproduction, and survival and might be a contributing factor to the extensive bird declines globally.

    And, of course, THEY think I'm the bad farmer!

  12. Pets, pesticides and polluted rivers

    "Fipronil and imidacloprid are widely used in flea treatments, which are typically applied to the back of the pet’s neck once a month.These two chemicals are extremely potent neurotoxic insecticides and it is deeply concerning that they are routinely found on the hands of dog owners through ongoing contact with their pet. Pet owners will also be upset to learn that they are accidentally polluting our rivers by using these products.”

    "The insecticides used in the flea products flow down household drains when pet owners wash their hands after applying the treatment. Wastewater from sewage treatment works is a leading source of fipronil and imidacloprid pollution in rivers, with concentrations exceeding safe limits for wildlife."

  14. Imported pests and broad-spectrum pesticide regulation

    "A “wildly toxic” chemical used to combat fire ants and the varroa mite in Australia is banned in Europe and harmful to humans – and it is poisoning waterways and killing native fauna, experts warn."

    "Australia is “a basket case” in that the chemical regulator answers to the department of agriculture, rather than to the department of health, as in Japan, the US and Europe, said Landos."

    "NSW MP Emma Hurst of the Animal Justice party said: “It is time for Australia to catch up to the rest of the world and ban fipronil.”"

  20. @flypapers

    “Our results demonstrated that [imidacloprid] IMD exposure significantly reduced the activity of a single focal olfactory neuron and delayed the return to baseline activity of the whole antenna.”

    “Flies exposed to IMD had a greater relative preference for ethanol-laced pineapple juice than control flies, demonstrating that neuronal shifts induced by IMD that we observed are associated with changes in relative preference.”

    Flies turning to booze was unexpected. Perhaps flies experience the feeling of being parasitised? At least larvae consume more alcohol when so, as a form of self-medication to kill parasitoid wasps.

    The first European Union member state to ban neonicotinoids, this Central European nation uses beekeeping as a means of raising awareness about the importance of biodiversity.

    Since 2022, Slovenian beekeeping culture has been on UNESCO's representative list of intangible cultural heritage.

  22. Pesticides: European experts propose ways to better assess risks for bees

    A slow race is coming to an end. Nearly 30 years after the first reports of honeybee colony collapse, following the arrival of neonicotinoids in the fields, the European Food Safety Authority (EFSA) has just adopted a new guidance document designed to improve the risk assessment of agricultural pesticides on honeybees, solitary bees and bumblebees.
