Analytical tools allowing the measurement of most pesticides and/or their metabolites to which the population can be exposed are also of need. In the present study, the limits of detection (LODs) of 3 different screening procedures based on either Low-Resolution and High-Resolution Mass Spectrometry (LR-MS and HR-MS) for the determination of pesticides in serum (among which carbamates, dithiocarbamates, neonicotinoids, organochlorines, organophosphates and pyrethroids) were explored. For HR-MS, a quadrupole time-of-flight was used in positive and negative electrospray ionization modes and data were obtained from either a targeted scheduled MSMS acquisition (HR-MSMS) or a data-independent acquisition (HR-DIA). For LR-MS, a triple quadrupole was used and data were acquired with a classical multiple-reaction monitoring (MRM) mode. Depending on the approach, the LOD values varied from 0.05 to 10 ng/mL. For the lowest concentrations, the proportion of molecules detected was systematically greater for the LR-MS approach, while those of HR-MSMS were better than those of HR-DIA. These differences in the LOD values were confirmed in a sample of 174 serums in which LR-MRM detected 89 compounds while HR-MSMS and HR-DIA detected 79 and 75 compounds, respectively. Nevertheless, for environmental and occupational purposes, HRMS approach could probably be efficient to detect most of pesticides and their metabolites in human serum and could be suitable for human biomonitoring studies or fundamental research exploring the impact of exposure to pesticides on human health.</p></div>","PeriodicalId":11725,"journal":{"name":"Environmental Technology & Innovation","volume":"36 ","pages":"Article 103834"},"PeriodicalIF":6.7,"publicationDate":"2024-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2352186424003109/pdfft?md5=6566fdce7dce2b3193d297963a00703c&pid=1-s2.0-S2352186424003109-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142272648","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results of SEM showed that rhombohedral and dumbbell-shaped minerals filled the pores of the sand column, and the elemental compositions were C, O, Ca, Al, and P. Various organic functional groups were discovered by FTIR. Mineral compositions were analyzed by X-ray diffraction (XRD). The results showed that the mineral components were calcite and aragonite, and the crystallinity of calcite improved with the increase in the bacterial concentrations. Stable carbon isotope analyses showed that the sand columns at different bacterial concentrations ranged from − 18.9 ‰ to − 21.4 ‰, which were more negative than chemical calcite with − 10.9 ‰. The mechanical properties of compression strength and splitting tensile strength proved that MICP could enhance the strength of sand columns. Thermodynamic characteristics were carefully investigated using thermogravimetric analysis from 50 °C to 1000 °C, which showed that the activation energy and thermal stability of the sand columns reinforced by MICP increased.

Polyethylene demonstrated over 90 % removal efficiencies for all the selected antibiotics. Data fitting into various models revealed Langmuir isotherm and Elovich kinetic model governed the adsorption. Antibiotics, excluding ciprofloxacin, followed second-order kinetics; ciprofloxacin was governed by pseudo-first-order kinetics. Pseudo-second-order kinetics had R² values of 0.9855, 0.9746, and 0.9997 for ofloxacin, sulfamethoxazole, and oxytetracycline, respectively. Elovich had R² values over 0.90 for all the antibiotics, with the order of values as oxytetracycline&gt;ofloxacin&gt;sulfamethoxazole&gt; ciprofloxacin. Langmuir Isotherm indicated the R² value of 0.9777, 0.9902, 0.9551, and 0.9959 for ofloxacin, ciprofloxacin, sulfamethoxazole, and oxytetracycline, respectively. Regeneration results exhibited that all antibiotics had greater than 80 % removal efficiencies in the first two cycles while the regeneration capacity of ciprofloxacin and sulfamethoxazole reduced to 75 % and 50 %, respectively at the fourth cycle.
