The residue of tetracycline from food and environment poses a potential threat to public health. Developing more convenient portable optical detection system has become demanding than fluorescence detection. This study describes sensor sulfur quantum dots (SQDs) with positively charged passivator for in the concentrations 0.20 100 μM limit 0.15 (3σ/k). A new sensing device was also designed smartphone as detector color change blue yellow-green upon addition tetracycline. In presence Eu3+, detectable is extended red. verification applied real lake water milk, standard recovery 93.1 109%. emissive excitation-independent SQD first ensures sensitive accurate analysis at very low demonstrates evident changes interaction application this method provided great convenience practical

Transformation products of antibacterial drugs in environmental water: Identification approaches based on liquid chromatography-high resolution mass spectrometry

Journal of Pharmaceutical and Biomedical Analysis, Journal Year: 2023, Volume and Issue: 238, P. 115818 - 115818

Published: Oct. 29, 2023

In recent years, the presence of antibiotics in aquatic environment has caused increasing concern for possible consequences on human health and ecosystems, including development antibiotic-resistant bacteria. However, once enter environment, mainly through hospital municipal discharges effluents wastewater treatment plants, they can be subject to transformation reactions, driven by both biotic (e.g. microorganism mammalian metabolisms) abiotic factors oxidation, photodegradation, hydrolysis). The resulting products (TPs) less or more active than their parent compounds, therefore inclusion TPs monitoring programs should mandatory. only reference standards a few known are available, whereas many other still unknown, due high diversity reactions environment. Modern high-resolution mass spectrometry (HRMS) instrumentation is now ready tackle this problem suspect untargeted screening approaches. handling large amount data typically encountered analysis environmental samples, these approaches also require suitable processing workflows accurate tandem spectra interpretation. compilation list containing monoisotopic masses retrieved from literature and/or laboratory simulated degradation experiments showed unique advantages. employment silico prediction tools could improve identification reliability. review, most strategies relying liquid chromatography-HRMS main antibiotic classes were examined, formed during water treatments disinfection not included.

Overlooked interconversion between tetracyclines and their 4-epimers in soil and effects on soil resistome and bacterial community

Environment International, Journal Year: 2024, Volume and Issue: 190, P. 108941 - 108941

With the widespread use of tetracycline antibiotics (TCs) and application manure fertilizer in farmland, TCs their metabolites especially 4-epimers have been heavily detected agricultural soil. However, existing studies focused on residual environmental behavior maternal TCs, few looked at ecotoxicity In this study, degradation interconversion (TC), oxytetracycline (OTC) (4-epitetracycline, ETC; 4-epioxytetracycline, OTC) were revealed. Their effects antibiotic resistance genes (ARGs), mobile genetic elements (MGEs) bacterial community soil also investigated comparison. The results showed that could be substantially transformed to parents degraded as a whole. rates four selected pollutants are followed: TC > OTC ETC EOTC. This indicated when entered soil, part into slower-degraded 4-epimers, these converted back parents, causing long-term residue When added alone, significantly promoted proliferation most ARGs MGEs, among them, trb-C, IS1247 IS1111 top three abundance. EOTC had little effect beginning. continuously after one month cultivation, treatments similar promoting indicating resistome was lagged mainly caused by parents. Nocardioides, unclassified_Rhizobiaceae, norank_Sericytochromatia, Microlunatus, Solirubrobacter norank_67-14 frequent hosts ARGs, Most which belong phylum Actinobacteria. Due large transformation slow rate potential microbes harm TCs' ecosystem cannot ignored.
