Kong W, Wang W, Jiang Y, Wang G, Ma F, Wu Y. Sorption of ciprofloxacin and enrofloxacin on alkaline cropland soil in semiarid regions: Roles of pH, ionic strength, and ion type. JOURNAL OF ENVIRONMENTAL MANAGEMENT 2024; 365:121565. [PMID: 38917539 DOI: 10.1016/j.jenvman.2024.121565] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/04/2024] [Revised: 05/31/2024] [Accepted: 06/18/2024] [Indexed: 06/27/2024]
Abstract
Animals manure and chemical fertilizers are widely applied to agricultural soils to mitigate soil fertility decline resulting from intensive farming practices. However, the use of antibiotics such as ciprofloxacin (CIP) and enrofloxacin (ENR) in these manures introduces certain environmental risks. The sorption of CIP and ENR in soil is influenced by various factors. Soil cations (i.e., Na+, K+, Mg2+, and Ca2+) and artificially introduced ions (NH4+) can affect the sorption behavior of CIP and ENR in alkaline agricultural soils through mechanisms such as ion exchange and competitive sorption. To investigate the effects of ionic strength and ion type on the sorption of antibiotics in alkaline agricultural soil, batch equilibrium experiments were conducted in this study. The results showed that the affinity of alkaline farmland soil to CIP and ENR was poor, and Kd was only 159 L/kg and 89 L/kg, respectively. Increases in temperature and pH inhibited CIP and ENR sorption on soil. Mineral elements in the soil strongly inhibited CIP and ENR sorption. Conversely, NH4+ promoted the Kd values of CIP and ENR by 46% and 221%, respectively. Additionally, under different influencing factors, both the sorption affinity (Kd) and sorption amount of ENR were lower than those of CIP. These findings indicate that ENR has a greater migration potential and poses a greater environmental risk in agricultural soils. Alkaline soil and mineral elements increase the migration potential of CIP, ENR, but the introduction of NH4+ in agricultural production can weaken the migration potential of them.

Wen J, Geng S, Zhu L, Yao X, Zhou Y, Shen F, Wang Z, Ma Y, Feng Y, Huo Z, Zhu F. Urinary antibiotic concentrations in preschool children from eastern China and health risk assessment. ENVIRONMENTAL SCIENCE AND POLLUTION RESEARCH INTERNATIONAL 2023:10.1007/s11356-023-28209-1. [PMID: 37326733 DOI: 10.1007/s11356-023-28209-1] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/27/2023] [Accepted: 06/07/2023] [Indexed: 06/17/2023]
Abstract
Despite limited biomonitoring studies suggesting extensive antibiotic exposure in general population, the body burden of antibiotics in young children and their potential health risks remain unclear. To assess the antibiotic exposure levels in young children, 508 preschoolers aged 3-6 years were recruited from eastern China in 2022, and a total of 50 representative antibiotics from 8 categories, including 17 human antibiotics (HAs), 4 antibiotics preferred as HAs (PHAs), 16 veterinary antibiotics (VAs), and 13 antibiotics preferred as VAs (PVAs), were analyzed by UPLC-MS/MS. Hazard quotient (HQ) and hazard index (HI) were calculated to evaluate the health risks, and multivariate logistic regression was applied to examine diet with antibiotic exposure. Our results showed that there were 41 antibiotics detected in children's urine, and the overall detection frequency was as high as 100%. Sulfonamides, macrolides, β-lactams, quinolones, and azoles were the predominant categories of antibiotic detected. Among the studied children, 6.5% had a sum of estimated daily intake (EDI) of all VAs and PVAs larger than 1 μg/kg/day. Notably, 10.0% of the children had a microbiological HI value exceeding 1, primarily contributed by ciprofloxacin. Children with higher consumption of seafood had a relatively increased exposure to multiple categories of antibiotics, including HAs, VAs, quinolones, azoles, and others. Principal component analysis suggested that "Aquatic products and viscera preferred dietary pattern" scores were positively correlated with the exposure levels of ciprofloxacin (OR: 1.23; 95% CI: 1.02-1.47) and carbadox (OR: 1.32; 95% CI: 1.10-1.59), and a relatively increased exposure of PHAs was realized in children with higher "Meat-egg preferred dietary pattern" scores (OR: 1.24; 95% CI: 1.03-1.50). In conclusion, there was a widespread exposure to antibiotics among preschool children from eastern China, and children who consumed more animal-derived foods may had an increased exposure to antibiotics.

Label free dual-mode sensing platform for trace level monitoring of ciprofloxacin using bio-derived carbon dots and evaluation of its antioxidant and antimicrobial potential. Mikrochim Acta 2023; 190:258. [PMID: 37303021 DOI: 10.1007/s00604-023-05830-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/16/2023] [Accepted: 05/05/2023] [Indexed: 06/13/2023]
Abstract
Being a persuasive antibiotic, ciprofloxacin is widely administered to patients and its excessive discharge has generated a keen interest among researchers for its detection in water resources. Therefore, the current work utilizes the virtues of carbon dots synthesized from the leaves of Ocimum sanctum as an economical and convenient bimodal stratagem for the detection of ciprofloxacin via an electrochemical and fluorometric approach. The insight into photostability, size, morphology, and optical studies of the carbon dots was tested to enhance their scope in sensing. The excellent photoluminescence-based excitation-dependent behavior with a quantum yield of 46.7% and non-requirement of any kind of labeled surface variations for amending their fluorescence and electrochemical properties have further supported the utilization of as-prepared carbon dots in trace-level monitoring of ciprofloxacin. The fluorescence emission intensity and peak current were enhanced by many folds via the application of Ocimum sanctum-derived carbon dots. The synergetic effect of carbon dots has possessed a linear relationship between the peak current/emission intensity within the range of 0 to 250 μM of ciprofloxacin and the lowest detection limit value was found to be 0.293 and 0.0822 μM with fluorometric and electrochemical methods, respectively. The sensor demonstrated excellent applicability for the estimation of ciprofloxacin and acts as a high-performance dual sensor for further applications.
