“…The current study indicated that at least nine different antibiotic drug classes were encountered in the retrieved literature. These antibiotics have been reported in various environmental compartments in various parts of the world [ 47 – 49 ]. The massive non-clinical use of antibiotics led to the presence of these antibiotics in large quantities in human-made environments such as sewage and wastewater treatment plants and marine environments [ 12 , 13 ].…”

Background: Antimicrobial resistance (AMR) is a global health threat that requires a "One Health" approach. Of the One Health triad, the environmental component is the most dynamic and most neglected. Therefore, the objective of the current study was to assess and analyze global research activity on AMR in the environment. Methods: This was a bibliometric descriptive study of publications on AMR in the environment. Publications were retrieved using SciVerse Scopus for the study period from 2000 to 2019. The search query was developed using terms and phrases related to the topic. The retrieved publications were analyzed for specific bibliometric indicators including annual growth, citation analysis, key players, research output for each world regions, research themes, and occurrences of different drug classes of antimicrobials. Visualization maps including research collaboration were created using VOSviewer program. The Hirsch (h) index was used to assess scientific impact. Results: There were 2611 research articles based on the implemented research query. The retrieved documents had an average of 22 citations per document and an h-index of 122. The annual number of publications showed a steep increase from 2011 to 2019. The major research themes in the field were (1) dissemination and abundance of antibiotic-resistant genes and (2) detection of bacterial strains or antibiotic residues in various environmental isolates. The bulk of the retrieved articles (n = 899; 34.4%) originated from the European region. China led with 598 (22.9%) documents. Four of the top 10 active institutions were in China. The top 10 active countries had relatively inadequate international research collaboration. The most commonly encountered antibiotic drug classes in the retrieved articles were penicillin/cephalosporin (n = 1152 occurrences). The most frequently encountered pathogen in the retrieved publications was E. coli (n = 666). The Science of the Total Environment journal was the most prolific journal with 139 (5.3%) publications. Conclusion: Scientific literature on the AMR in the environment has witnessed a steep growth lately with a leading role of China and Chinese institutions. Data on AMR in the environment need to be collected from all world regions including the Eastern Mediterranean and African regions through research collaboration and funding of research in this field.

“…For example, an European study covering Cyprus, Finland, Germany, Ireland, Norway, Portugal, and Spain identified only three compounds (ciprofloxacin, azithromycin and cefalexin) from a list of 50 antibiotics to be considered as markers of antibiotic pollution (Rodriguez-mozaz et al, 2020). As stated earlier, sulfamethoxazole and trimethoprim are more prevalent in Africa (Faleye et al, 2018;Madikizela et al, 2020) while in Asia, studies have observed higher concentrations for various antibiotics mainly fluoroquinolones (Jia et al, 2012;Jiang et al, 2014;Shi et al, 2020;Zafar et al, 2021). These variations are an indication of the need of more region-specific studies.…”

One of the major concerns in the consumption of antibiotics is the discovery of antibacterial resistant genes due to prolonged exposure which makes their presence in environmental samples a priority. In this study, we screened 52 antibiotics along a South African stream polluted with wastewater effluents and municipal dumpsite leachates. Of these antibiotics, 15 were detected in the stream while 3 sulfonamides (sulfamethizole, sulfamethazine, sulfamethoxazole), a fluoroquinolone (flumequine) and a diaminopyrimidine (trimethoprim) were further quantified. The concentrations of sulfamethizole, sulfamethazine, sulfamethoxazole ranged from not detected to 0.133 µg L−1, flumequine ranged from 0.222 to 0.686 µg L−1, while trimethoprim was up to 0.0618 µg L−1. The highest concentrations were recorded at the point source discharge with most antibiotics not detected further downstream. The current study has further confirmed wastewater effluents and dumpsite leachates as pathways of antibiotics into the environment. Only the persistent unsanctioned antibiotic, flumequine had its risk quotient above 0.1 making it an antibiotic of environmental concern. Multiresidue studies are still limited in Africa and the current study offers a platform for a research paradigm shift with more studies expected to emerge providing an improved overview of the release of antibiotics and other pharmaceuticals into Africa’s vulnerable surface water systems.

“…is mentioned as a useful and available technology to eradicate pharmaceuticals from wastewater systems(Park &Oh 2020, Pilli et al 2020, Quintelas et al 2020, Wang et al 2020) and our ndings show that WWTP B by activated sludge system have removed antibiotics better than WWTP A.In other studies Yungang Shi et al in China estimated the average removal e ciency of antibiotics in municipal WWTPs at 57-95%(Shi et al 2020). Despite the high concentration of antibiotics in e uent in this study, the removal e ciencies of target antibiotics are in this range, and it seems that two studied WWTPs have performed well at removing antibiotics.…”

Antibiotics are non-biodegradable drugs that used to inhibit the expansion and growth of microorganisms. The presence of antibiotics and their residues in the environments has resulted in an increased universal concern due to their contrary impacts on human healthiness and also the environment. Specially with the prevalence of Covid-19, the consumption of antibiotics to treat or prevent secondary infections have increased. Therefore, the presence of most prescribed antibiotics from ß-lactam class including amoxicillin and cephalexin were studied at two municipal WWTPs in Isfahan. Analytical method was extracted and then detected via HPLC/UV. Samples were collected from 2 wastewater treatment plants (WWTPs) on 13 sampling periods over 2 months on February and March 2020 during the outbreak of Covid-19. In WWTP A, the average concentration of amoxicillin in influent, effluent, and its removal efficiency was equal to 509.64 ± 161.97µg/l, 354.37 ± 201.41µg/l, 33.69 ± 30.22%, and the average concentration of cephalexin in influent, effluent, and its removal efficiency was 189.42 ± 176.06µg/l, 44.35 ± 43.72µg/l, 64.61 ± 26.52%, respectively. In WWTP B, the average concentration of amoxicillin in influent, effluent, and its removal efficiency was equal to 2134.82 ± 3031.53µg/l, 401.09 ± 205.86µg/l, 54.82 ± 33.29%, and the average concentration of cephalexin in influent, effluent, and its removal efficiency was183.69 ± 123.48µg/l, 40.64 ± 33.02µg/l, 72.89 ± 19.45, respectively. According to statistical points of view, the concentration of antibiotics in both WWTPs had significant differences and no critical correlation between removal efficiency of antibiotics with other principle wastewater parameters was observed.
