The estimation and quantification of colistin and carbapenems in environmental samples is challenging due to their low concentrations, complex structures, stability issues, and potential interference from other substances. Despite known side-effects, the biological impacts of their residues recirculated in the environment has not yet been evaluated. This review provides an in-depth analysis of these two critical drugs by exploring their chemical and biological properties and current detection. This is based on 41 analytical studies on their quantitation methods, with 7 studies being from environmental matrices and the rest being from biological matrices. Reverse-phased chromatography and high-performance liquid chromatography tandem mass spectrometry are the main instruments due to their polar nature. We also discuss the growing challenges associated with their release into environmental settings. We focus on the environmental entry pathways of these antibiotic residues, as well as the development of resistance. These antibiotics primarily enter the environment through runoff from hospitals and agricultural sites, leading to their accumulation in wastewater, soil, and natural water bodies. This environmental exposure is particularly of concern due to the potential for resistance development. The spread of resistance genes is a complex process, often involving mechanisms like horizontal gene transfer, which are facilitated by the presence of these antibiotic residues in the environment. Further research is crucial in understanding the environmental release of these critical antibiotics, the analytical methods of their quantifycation in environmental settings, and their role in the dissemination of antimicrobial resistance.</p></div>","PeriodicalId":94356,"journal":{"name":"Soil & Environmental Health","volume":"2 1","pages":"Article 100058"},"PeriodicalIF":0.0,"publicationDate":"2024-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2949919424000013/pdfft?md5=8a4ca87dd3c53e71d5c873fbfd9fa553&pid=1-s2.0-S2949919424000013-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139632755","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we investigated the adsorption of a quinolone antibiotic (nalidixic acid, NA) and an anti-inflammatory agent (niflumic acid, NFA) onto two soils from France and Sweden in water-saturated soil columns. Despite its lower hydrophobicity, adsorption of NA is much greater than NFA, which can be ascribed to the presence of both carbonyl and carboxylic groups in NA molecule. The data suggest that adsorption to soil components can mainly take place through hydrogen bonding and surface complexation mechanisms, prevailing over hydrophobic interactions. Accordingly, more sorption of NA and NFA was observed in the Swedish soil because it contains more clay content, and much higher Al and Fe contents than the French soil. Injection of NA/NFA mixture in the column did not modify the breakthrough behavior compared to single systems, although cooperative adsorption was observed under static batch conditions. Ca<sup>2+</sup> inhibited NA adsorption by forming a soluble NA-Ca<sup>2+</sup> complex but promoted NFA adsorption both in single and binary systems. The mobility in soil columns was well predicted using a new transport model that accounts for both kinetics and binding reactions of NA and NFA to soil constituents.

Soil As contamination is a critical issue for environmental and agricultural sustainability. Rapid global urbanization and agricultural and industrial expansion release toxic metal (loid)s including As into the soil. Arsenic contamination disrupts the rhizosphere ecosystem, affecting plant health, microbial communities, and overall soil functionality. Ensuring soil health in the face of As contamination is imperative for human well-being and for developing a resilient, sustainable environment. This review signifies the need for comprehensive strategies to revitalize soil ecosystems, promoting resilience and long-term ecological balance. Advanced biotechnological approaches, particularly bioremediation including phytoremediation, microbial remediation, mycoremediation, nano-remediation, and other integrative strategies, are highlighted for their effectiveness in addressing As contamination and promoting soil health. Conventional physico-chemical techniques make soil unsuitable for agriculture by disrupting the microenvironment. Consequently, the urgent need for remediation of As-contaminated soil demands the adoption of eco-friendly and sustainable approaches, such as bioremediation, phytoremediation, and rhizoremediation, to enhance soil health.</p><p>Development of transgenic lines and genetically modified organisms are effective tools in reducing the As burden. Bacteria including <em>Sphingomonas desiccabilis</em>, <em>Bacillus subtilis</em> and <em>Bacillus idriensis</em> expressing the <em>arsM</em> gene all show promising results to reduce the As burden. Transgenic rice, incorporating the <em>arsM</em> gene from <em>Rhodopseudomonas palustris</em>, demonstrated 10 times more volatile arsenicals and reduced As accumulation in the grain. Additionally, the use of As-hyperaccumulating plants and conventional methods, like chemical-assisted phytoextraction, show potential for decontaminating As- contaminated soil.

Although the feasibility of phytoremediation has been proven in the last decades, its performance is uncertain due to the complex interactions among soil, water, plants, weather, microorganisms, and pollutants, leading to its underutilizing globally. This paper aims to review the representations and methods for quantifying key phytoremediation processes via modelling. We examine the structures, methods and ability of phytoremediation models that characterize the biogeochemical, hydrological, and phenological processes accountable for phytoremediation dynamics, along with discussions about their advantages and limitations. Then, we identify the knowledge gaps and challenges in incorporating biogeochemical, hydrological, and phenological processes into phytoremediation models in contaminated sites and representing spatial heterogeneity and temporal variability in large-scale applications. The existing phytoremediation models are difficult to predict the phytoremediation period under real environmental conditions but it is a key assessment of phytoremediation performance and cost. Finally, we explore the opportunities to integrate the current knowledge from other disciplines, such as soil, agriculture, ecology, and plant research in a competition-based model. We highlight the key research priorities for effective integration of knowledge based on physical, chemical, and biological processes in modelling phytoremediation, including biogeochemical processes, soil amendments and agro-practices.

This research examined how variations in CuO-NP size (10, 40, and 80 ​nm), surface coatings (polyvinylpyrrolidone and polyacrylic acid), and concentrations (100, 250, and 500 ​mg/kg) influenced the extractable Cu in soil and their impacts on selected soil enzymes (acid phosphatase and dehydrogenase).

The bioactive Cu related to CuO-NPs as determined via CaCl<sub>2</sub> and DTPA extractions indicated that 10 ​nm CuO-NPs had the highest extractable Cu across all incubation times. Besides, polyvinylpyrrolidone and polyacrylic acid coating had little impact on extractable Cu compared to uncoated ones. Unlike CuSO₄, extractable Cu concentrations in CuO-NPs spiked soil increased over time. CuO-NPs dissolution was negatively correlated with soil pH. CuO-NPs after 24 ​h short-term exposure significantly inhibited both enzyme activities across all tested concentrations, with smaller NPs showing greater effect. However, reduced toxicity to enzyme activities was observed after 30 days. A strong negative correlation was observed between CuO dissolution and enzyme activities after 1 and 30 days, indicating Cu ions are the main toxicity source.

The effects of biochar and biostimulants on forms of nitrogen and carbon in soil during a field-scale incubation were investigated by a multi-analytical approach. This study was conducted on a tomato-cultivated agricultural land treated with low doses of biochar (about 0.1%) and different biostimulants: Micosat F®, arbuscular mycorrhiza fungi (AMF), or a consortium of <em>Pseudomonas fluorescens</em>, <em>Bacillus</em> sp., and a nitrogen-fixing bacteria (Consortium B). Forms of carbon and nitrogen and their mobility before, during, and after tomato growth, were studied with different techniques including elemental analysis, adsorption and molecular fluorescence spectroscopy, ion chromatography, and a column leaching test. Due to the low load of biochar and the short study time, elemental analyses might not be sensitive enough to determine C and N variation in the soil. Based on the dissolved organic carbon (DOC) and dissolved nitrogen forms, the treatments with biochar and biostimulants affected the mobility of these elements with an overall decrease at the end of tomato growth. The organic carbon is mainly ascribable to humic and fulvic acids, as indicated by spectroscopic analysis. The leaching column test demonstrated that cumulative leached C is about one order of magnitude lower than the DOC. In addition, simulated rain cycles profoundly affected their leaching, so it is important to design leaching tests based on local and seasonal weather conditions.
