Ecological criteria for antibiotics in aquatic environments based on species sensitivity distribution

Ecotoxicology and Environmental Safety, Journal Year: 2024, Volume and Issue: 287, P. 117261 - 117261

Due to the substantial production and use of antibiotics, they inevitably remain in aquatic environments, posing a serious threat ecosystems. However, there are currently no criteria antibiotics for ecological risk water environment. In present study, three types (tetracyclines, sulfonamides quinolones) that often detected environments were investigated. Toxicity data regarding bacteria, algae, plants, invertebrates vertebrates selected, species sensitivity distribution was used obtain organisms. Animals least sensitive antibiotics. The overall toxicity is most bacteria cyanobacteria, followed by green algae plants. recommended tetracyclines, quinolones, 22, 17, 94 μg/L, respectively. Ofloxacin needs be with caution because it has small acute predicted no-effect concentration (PNEC) 0.6 μg/L. criterion chronic total determined 1.4 PNECs measured quinolone, tetracycline, sulfonamide 0.5, 2.2, 2.4 Norfloxacin had highest zone 353, indicating poisoning likely occur. Moreover, an exponential correlation between PNEC PNEC. addition, quantitative structure-activity relationship model constructed These findings can expand threshold on effects organisms, provide theoretical basis environmental assessment

Comparison of Established and Novel Insecticides on Survival and Reproduction ofFolsomia candida

Environmental Toxicology and Chemistry, Journal Year: 2023, Volume and Issue: 42(7), P. 1516 - 1528

Published: April 10, 2023

Neonicotinoids have been among the most widely and abundantly used insecticides for of current century. The effects these substances on nontarget terrestrial aquatic organisms resulted in a significant decrease their use many parts world. In response, application several novel classes including diamides, ketoenols, pyridines, butenolides has significantly increased. hexapod subclass Collembola is an ecologically distributed group soil invertebrates often found leaf litter surficial soils. We exposed parthenogenic collembolan species Folsomia candida to six sandy loam 28 days, two neonicotinoids (thiamethoxam clothianidin), diamide (cyantraniliprole), ketoenol (spirotetramat), pyridine (flonicamid), butanolide (flupyradifurone) assess effect each insecticide survival reproduction. Clothianidin, thiamethoxam, cyantraniliprole (median effective concentration [EC50] values reproduction: 0.19, 0.38, 0.49 mg/kg soil, respectively) had greater reproduction F. than flupyradifurone, spirotetramat, flonicamid (EC50 0.73, >3.08, 5.20 respectively).

Due to its high mobility and bioavailability, hexavalent chromium [Cr(VI)] in agricultural soil can be taken up by crops pose threat human being. In this study, two soils (Jiangxi red Shandong fluvo-aquic soil) spiked with Cr(VI) 8 common vegetable varieties were used conduct the pot experiment. The bioconcentration factor (BCF) values based on tetraacetic acid extractable Cr (EDTA-Cr) construct species sensitivity distribution (SSD) curve. Afterwards, threshold was derived critical BCF value permissible limit of for vegetables. results showed that when 5.6 mg kg-1 Cr(Ⅵ), EDTA-Cr concentrations significantly increased compared control except Jiangxi planted carrot radish, while edible parts vegetables both below (0.5 FW). However, there are dramatic differences accumulation different Apparent discrepancy observed between carrot. Among leafy vegetables, lettuce oilseed rape most least sensitive pollution, respectively. safety 0.70 0.85 soil, This study provides information production products Cr(Ⅵ) polluted is helpful revision quality standards Cr.

A Novel Full-length IgG Recombinant Antibody Highly Specific to Clothianidin and Its Application in Immunochromatographic Assay

Biosensors, Journal Year: 2022, Volume and Issue: 12(4), P. 233 - 233

Published: April 11, 2022

The toxicity of clothianidin to non-target organisms has gradually attracted world-wide attention. It is essential develop reliable methods for the on-site detection residue. In this study, analogue-based heterologous ic-ELISAs were designed rapidly screen desirable hybridomas, which could be used construction recombinant antibodies (RAbs) against clothianidin. Based on antibody variable region genes, two full-length IgG RAbs (1F7-RAb and 5C3-RAb) produced by mammalian cell expression system. performance was characterized compared non-competitive surface plasmon resonance (SPR) assays. Using ic-ELISAs, 1F7-RAb exhibited highly specific sensitive recognition with an IC50 4.62 μg/L, whereas 5C3-RAb bind both dinotefuran. results SPR assay further verified that had a higher specificity affinity than 5C3-RAb. Finally, gold immunochromatographic based novel antibody, 1F7-RAb, developed rapid high sensitivity (visual limit 2.5 μg/L), specificity, good reproducibility, can as effective supervision tool residue in agricultural environmental samples.

Silver nanoparticle-modified electrodes for the electrochemical detection of neonicotinoid pesticide: clothianidin

Analytical Methods, Journal Year: 2022, Volume and Issue: 14(45), P. 4643 - 4648

Published: Jan. 1, 2022

For the first time, stable silver nanoparticles with a diameter less than 20 nm were prepared using SDS as reducing and stabilizing agent characterized, then used to construct modified electrodes. The developed electrodes are more catalytically active towards reduction of clothianidin. Clothianidin undergoes at -300 mV vs. Ag/AgCl on nanoparticle-modified electrode, whereas no peak was observed bare glassy carbon electrode (GCE). detection limit found be 2.4 nM. potential limits reported in this work lower ever literature. analytical validity clothianidin tested tomatoes. Validation electrochemical results has been achieved by comparing them HPLC results. There is good agreement between those obtained HPLC. proposed sensor opens up new possibilities for sensing environmental samples.
