Remediation technologies for neonicotinoids in contaminated environments: Current state and future prospects

Environment International, Journal Year: 2023, Volume and Issue: 178, P. 108044 - 108044

Published: June 16, 2023

Neonicotinoids (NEOs) are synthetic insecticides with broad-spectrum insecticidal activity and outstanding efficacy. However, their extensive use persistence in the environment have resulted accumulation biomagnification of NEOs, posing significant risks to non-target organisms humans. This review provides a summary research history, advancements, highlighted topics NEOs remediation technologies mechanisms. Various approaches been developed, including physiochemical, microbial, phytoremediation, microbial physicochemical being most extensively studied. Recent advances physiochemical led development innovative adsorbents, photocatalysts, optimized treatment processes. High-efficiency degrading strains well-characterized metabolic pathways successfully isolated cultured for remediation, while many plant species shown great potential phytoremediation. challenges gaps remain this field. Future should prioritize isolating, domesticating or engineering high efficiency, NEO degradation, as well developing synergistic techniques enhance removal efficiency on multiple varying concentrations different environmental media. Furthermore, shift from pipe-end pollution prevention strategies is needed, green economically efficient alternatives such biological insecticides. Integrated case-specific that can be applied practical projects need along clarifying degradation mechanisms improve efficiency. The successful implementation these will help reduce negative impact human health.

Removal of neonicotinoid insecticide clothianidin from water by ozone-based oxidation: Kinetics and transformation products

Separation and Purification Technology, Journal Year: 2023, Volume and Issue: 316, P. 123735 - 123735

Published: April 2, 2023

In this paper, reaction kinetics, degradation mechanisms and associated toxicity have been assessed in detail concerning the abatement of neonicotinoid insecticide clothianidin (CLO) by ozone-based oxidation water. The second-order rate constants for CLO with molecular ozone (O3) hydroxyl radical (OH) were determined direct competition kinetics (with UV/H2O2 system as source) methods, respectively, estimated to be 103 M−1 s−1 3.7·109 s−1. This suggested a (potential) higher contribution indirect mechanism rather than degradative pathway ozonation process. Additionally, was studied through an O3 O3/H2O2 three complex real water matrices distinct characteristics. DOC content found main parameter responsible making difficult achievement high degradations, whereas carbonate alkalinity did not exert great impact on process efficiency. Results indicated that typical doses (up 1 mg O3/mg DOC) enough complete removal micropollutant, ranging only from 50 80%. study transformation products (TPs), performed means high-resolution mass spectrometry, allowed suggest potential routes based five major CLO-TPs identified. It inferred OH involved formation all TPs, two them. A preliminary assessment its TPs during conducted at different trophic levels via ECOSAR software. showed none compounds classified very toxic aquatic organisms, exhibited minor parent compound. Changes structure, such chlorothiazole ring breakdown, could reason considerable decrease toxicity. Overall, present demonstrates can considered suitable technology alternative (and toxicity) aqueous matrices.

Ecological risk assessment for xylenes and propylbenzenes in aquatic environment using a species sensitivity distribution approach

Ecotoxicology and Environmental Safety, Journal Year: 2023, Volume and Issue: 261, P. 115106 - 115106

Published: June 7, 2023

Xylenes and propylbenzenes (PBZs) are volatile aromatic hydrocarbons with high aquatic toxicity. can be present in three isomers: o-xylene (OX), m-xylene (MX), p-xylene (PX), while PBZs include two n-propylbenzene (n-PBZ) isopropylbenzene (i-PBZ). Their accidental spills improper discharges from petrochemical industries cause severe contamination water bodies posing potential ecological risks. In this study, the published acute toxicity data of these chemicals for species were collected to calculate hazardous concentrations protecting 95% (HC5) using a sensitivity distribution (SSD) approach. The HC5 values OX, MX, PX, n-PBZ, i-PBZ estimated 1.73, 3.05, 1.23, 1.22, 1.46 mg/L, respectively. risk quotient (RQ) calculated based on indicated their (RQ: 1.23 ∼ 21.89) groundwater, but low (RQ < 0.1) natural seawater, river water, lake water. When xylenes or leaked into sea, they expected pose > 1) at start then after 10 days due attenuation.
