“…There are a handful of review articles on the occurrence, fates, sources, and hazards of antibiotics in global waters [ 8 , 20 ]. Considering that antibiotics have been observed in different environments—including groundwater [ 21 ], lakes [ 22 ], surface water [ 23 ], soils [ 24 ], and sewage [ 25 ]—and due to the threat posed by antibiotics to human health and other organisms [ 26 ], reviewing the latest published works on antibiotics is informative and important. Accordingly, this study was designed to review the occurrence of antibiotics in different parts of marine environments (i.e., water, sediments, and biota) worldwide.…”

Antibiotics, as pollutants of emerging concern, can enter marine environments, rivers, and lakes and endanger ecology and human health. The purpose of this study was to review the studies conducted on the presence of antibiotics in water, sediments, and organisms in aquatic environments (i.e., seas, rivers, and lakes). Most of the reviewed studies were conducted in 2018 (15%) and 2014 (11%). Antibiotics were reported in aqueous media at a concentration of <1 ng/L–100 μg/L. The results showed that the highest number of works were conducted in the Asian continent (seas: 74%, rivers: 78%, lakes: 87%, living organisms: 100%). The highest concentration of antibiotics in water and sea sediments, with a frequency of 49%, was related to fluoroquinolones. According to the results, the highest amounts of antibiotics in water and sediment were reported as 460 ng/L and 406 ng/g, respectively. In rivers, sulfonamides had the highest abundance (30%). Fluoroquinolones (with an abundance of 34%) had the highest concentration in lakes. Moreover, the highest concentration of fluoroquinolones in living organisms was reported at 68,000 ng/g, with a frequency of 39%. According to the obtained results, it can be concluded that sulfonamides and fluoroquinolones are among the most dangerous antibiotics due to their high concentrations in the environment. This review provides timely information regarding the presence of antibiotics in different aquatic environments, which can be helpful for estimating ecological risks, contamination levels, and their management.

“…DO values can affect the biodegradation rates of PPCPs with higher biodegradation rates under aerobic conditions than under anaerobic conditions; therefore, the negative correlation between PPCPs and DO revealed that DO may influence PPCP degradation and subsequent distribution, which can explain the shift in PPCP compositions during transportation (Figure S4). The significant negative correlation between PPCPs and DO has also been reported in Xinjiang Uygur Autonomous Region, Honghu Lake, and typical marine aquaculture farms in the Yellow Sea . In addition, positive correlations between several PPCPs, such as BT and BZT ( r = 0.85, P = 0.00), BPA and BPZ ( r = 0.30, P = 0.04), PPZ, IBU, KPF, lincomycin, and PHZ ( r = 0.31–0.53, P < 0.05) were observed (Figure S8), indicating that they have similar sources ,, and similar environmental behaviors.…”

“…Similarly, a negative correlation between PPCPs and salinity has been reported in the seawater of Yellow Sea and East China Sea, and the Jiulong River estuary . DO values can affect the biodegradation rates of PPCPs with higher biodegradation rates under aerobic conditions than under anaerobic conditions; therefore, the negative correlation between PPCPs and DO revealed that DO may influence PPCP degradation and subsequent distribution, which can explain the shift in PPCP compositions during transportation (Figure S4).

“…The global market is experiencing a rapid depletion of antibiotics, with an annual production rate of 100 000–200 000 tons . The antibiotic overexposure rate is expected to increase from 42.3 billion (2015) to 128 billion (2030) . At present, a large number of antibiotics are released into the environment during mass production and consumption, resulting in intricate and toxic effluents.…”

Toxic antibiotic effluents and antibiotic-resistant bacteria constitute a threat to global health. So, scientists are investigating high-performance materials for antibiotic decomposition and antibacterial activities. In this novel research work, we have successfully designed ZIF-8@ZIF-67 nanocomposites via sol–gel and solvothermal approaches. The ZIF-8@ZIF-67 nanocomposite is characterized by various techniques that exhibit superior surface area enhancement, charge separation, and high light absorption performance. Yet, ZIF-8 has high adsorption rates and active sites, while ZIF-67 has larger pore volume and efficient adsorption and reaction capabilities, demonstrating that the ZIF-8@ZIF-67 nanocomposite outperforms pristine ZIF-8 and ZIF-67. Compared with pristine ZIF-8 and ZIF-67, the most active 6ZIF-67@ZIF-8 nanocomposite showed higher decomposition efficacy for ciprofloxacin (65%), levofloxacin (54%), and ofloxacin (48%). Scavenger experiments confirmed that • OH, • O 2– , and h + are the most active species for the decomposition of ciprofloxacin (CIP), levofloxacin (LF), and ofloxacin (OFX), respectively. In addition, the 6ZIF-67/ZIF-8 nanocomposite suggested its potential applications in Escherichia coli for growth inhibition zone, antibacterial activity, and decreased viability. Moreover, the stability test and decomposition pathway of CIP, LF, and OFX were also proposed. Finally, our study aims to enhance the efficiency and stability of ZIF-8@ZIF-67 nanocomposite and potentially enable its applications in antibiotic decomposition, antibacterial activities, and environmental remediation.
