Abstract Neonicotinoids are the most widely used class of insecticides globally. However, link between farming practices and extent contamination soils crops by neonicotinoid insecticides, as well such in organic fields ecological focus areas (EFAs) currently unclear. We measured concentrations five (imidacloprid, clothianidin, thiamethoxam, thiacloprid, acetamiprid) 702 soil plant samples 169 cultivated EFAs from 62 conventional, integrated production farms distributed over entire lowland Switzerland. detected neonicotinoids 93% crops, more than 80% EFA plants—two types arable land supposedly free insecticides. also tested 16 seeds, which 14 were positive for neonicotinoids. Finally, we calculated hazard quotients (HQs) potentially affected fractions 72 beneficial 12 pest species. Under a field‐realistic scenario, found that 5.3%–8.6% above‐ground invertebrate species may be exposed to lethal 31.6%–41.2% sublethal concentrations, “integrated production” conventional fields. 1.3%–6.8% (up 12.5% based on HQs) In contrast, no would even under worst‐case scenario.

Neonicotinoid use has increased rapidly in recent years, with a global shift toward insecticide applications as seed coatings rather than aerial spraying. While the of can lessen amount overspray and drift, near universal prophylactic neonicotinoid on major agricultural crops led to widespread detections environment (pollen, soil, water, honey). Pollinators aquatic insects appear be especially susceptible effects neonicotinoids current research suggesting that chronic sublethal are more prevalent acute toxicity. Meanwhile, evidence clear consistent yield benefits from remains elusive for most crops. Future decisions will benefit weighing crop versus environmental impacts nontarget organisms considering whether there environmentally benign alternatives.

Neonicotinoids have become the most widely used insecticides in world since introduced mid 1990s, yet extent of human exposure and health impacts is not fully understood. In this study, residues were analyzed seven neonicotinoids fruit vegetable samples collected from two cross-sectional studies: U.S. Congressional Cafeteria study (USCC) Hangzhou China (HZC) study. We then employed a relative potency factor method to integrate all each food sample using respective reference dose values as basis for summation. The findings compared with data published by Department Agriculture Pesticide Data Program (USDA/PDP). Imidacloprid thiamethoxam commonly detected fruits vegetables 66 51% detection HZC 52 53% USCC respectively. overall frequency USDA/PDP was much lower than those reported here or studies, imidacloprid being frequently neonicotinoid at 7.3%. high frequencies studies give us snapshot ubiquity use global agriculture make it clear that part dietary staple, possible implications individuals.

Pesticides are applied in large quantities to agroecosystems worldwide. To date, few studies assessed the occurrence of pesticides organically managed agricultural soils, and it is unresolved whether these pesticide residues affect soil life.
