Proclivities for prevalence and treatment of antibiotics in the ambient water: a review

Abstract

In the intial two decades of the twenty-first century, antibiotic (AB) resistance in human pathogens has emerged as a major challenge for water, sanitation, and public health. Considering these challenges, we critically reviewed AB-related studies with particular emphasis on their (i) patterns of consumption, (ii) pathway prevalences and environmental implications in ambient waters, and (iii) benefits and limitations of existing AB removal/purging techniques. We found that lifestyle, land use, urbanization, the ease of availability, and the tendency of the medical practitioners to recommend ABs are the key factors governing the AB use pathway and enrichment in the environment. In the developing world, the most prevalent group of ABs is quinolone, whereas in the developed world, older-generation AB groups are most prevalent. Further, enormous variability in the consumption of ABs around the globe is explicitly highlighted in this study. Ciprofloxacin has been reported in the highest concentration among all the ABs with 28–31 mg L−1 in the raw wastewater of the Indian subcontinent. We found that adsorption may be one of the most efficient AB removal techniques, and NaOH-activated carbon prepared from Macadamia nut shells is the most effective adsorbent identified to date. The literature showed that the Langmuir isotherm and pseudo-second-order kinetic model explain the AB adsorption mechanism most effectively. The future challenge lies in developing advanced protocols and markers to prioritize the strategy and simulate the ecotoxicities of the individual and a mixture of ABs.

Water Self-Purification with Zero External Consumption by Livestock Manure Resource Utilization

“…TC is one of the typical ECs in the class of antibiotics . Residual TC in the environment can affect the growth of aquatic animals and plants, which potentially endanger human health through the food chain . Here, TC was used as the target pollutant to investigate the self-purification performance of the Fe-CCM system.…”

Occurrence and toxicity impact of pharmaceuticals in hospital effluents: Simulation based on a case of study

“…Herein, this last effluent is reported to contained up to three times higher chemical load than others (Verlicchi, 2021;Verlicchi et al, 2012). In recent literature, the detection of common antibiotics in surface water was reported to range 1.7-524 ng dm -3 of clarithromycin (Boleda et al, 2011;Padhye et al, 2014), 32.3-2,910 ng dm -3 of erythromycin during different seasons (Yao et al, 2017), 1-200,000 ng dm -3 of amoxicillin (Bhagat et al, 2020), 62-80 ng dm -3 of chloramphenicol (Tran et al, 2016) in WWTPs or 29-67 ng dm -3 of norfloxacin (Leung et al, 2012). Additionally, ibuprofen, diclofenac and ketoprofen (anti-inflammatory and analgesic drugs) were found at concentrations of 43.7-2,014.7 ng dm -3 in groundwater from China.…”

Recent Advances in the Applications of Carbon Nanostructures on Optical Sensing of Emerging Aquatic Pollutants

“…The use of various pharmaceuticals, including antibiotics, analgesics, and hormonal stimulants, like human medicine and veterinary drugs, has led to their continual introduction into the environment [36] . To this end, antibiotics such as ciprofloxacin are the most prevalent contaminants among pharmaceuticals, with concentrations up to 28–31 mg/L in wastewater of developing countries [37] . Personal‐care products (PCPs) are a mixture of chemicals used to improve living standards, e. g., preservatives, pH regulators, and emulsifiers.…”

[37] Personal-care products (PCPs) are a mixture of chemicals used to improve living standards, e. g., preservatives, pH regulators, and emulsifiers. For example, paraben and 4methyl-benzylidene-camphor (4-MBC) are the widely used PCPs for preservative and sunscreen ultraviolet filters, respectively.…”
