Indian River systems have remained the epitome of pollution due to unregulated treatment and discharge of pollutants from different sources. Therefore, this studies providing an adequate sound knowledge of identifying ECs in Indian rivers become of utmost importance. The current study focuses on the identification of ECs in the Ganges in three major cities, respectively, in three belts of Indo-Gangetic plains. Hydroxymorphinan, picrotoxinin, antibiotic quinolone, and nefopam are common drugs found at different locations in the Ganga basin. ECs and the frequency of each EC have been identified for various locations and estimated with some basic consideration. Interestingly, Ethylhexyl ester is primarily used in pesticide manufacturing and is a common problem for the middle and lower Ganga basins. Besides, personal care products, insecticides, herbicides, pesticides, and flavoring agents are major sources of ECs in the Ganga basin. The trends of concentration of various ECs from upper towards downstream were analyzed and justified with sources.

Besides, it can reduce the carbon budget of the ocean through seaweed farms and act as a CO<sub>2</sub> sink. In the context of climate change mitigation, the seaweed culture is the energy crop, and during its entire life cycle can serve as a bio-filter and bio-extractor. The climate change effect can be reduced by farming seaweed on a commercial scale and it will protect the coastal area by decreasing the physical damage through damping wave energy. The seaweed can reduce eutrophication by removing excess nutrients from water bodies and releasing oxygen as a byproduct in return. The cultivation of seaweed plays an important role as the source of bioenergy for full fill the future energy requirement and it will act as clean energy through the establishment of algal biorefinery along with the seaweed cultivation site.

Antibiotics, due to their accumulation in freshwater sources and wastewater have become a pollutant of concern. Every year million tons of these emerging contaminants are discharged into the water bodies. Through, the feces and urine of humans and animals, the antibiotics and their metabolites enter the environment. Aquatic ecosystems are exposed to persistent pollutants as they escape the wastewater treatment process. Excessive usage of antibiotics has resulted in the generation of antibiotic-resistant genes and bacteria in the environment. To maintain the vitality of the environment, it becomes imperative to mitigate antibiotics and their toxic metabolites. To avoid the adverse consequences on the non-target organisms, their removal from the environment is vital. Various remediation methods such as conventional methods including ion exchange, and precipitation are used for antibiotics degradation, however, the efficacy of the traditional methods is limited due to the production of toxic sludge and the high cost of maintenance. Biological methods such as bioremediation and phytoremediation are sustainable strategies to eradicate antibiotics, hence used widely. There are many reviews on antibiotic bioremediation using microbes and phytoremediation of antibiotics. But not all antibiotics can be remediated using microorganisms, so there is a need for more sustainable removal methods and recent remediation strategies. In the present review, a web-based search for literature published between 2010 and 2022 is carried out. Previous studies reported that living organisms like bacteria, fungi, algae, and plants could be utilized for the degradation of antibiotics. But not all antibiotics could be degraded using bacteria, as bioremediation may get affected by many factors such as inoculum size, microbial strain, and the culture conditions. Therefore, recent remediation techniques such as the use of microbial fuel cells, biochar, and sawdust are used for the possible removal of antibiotics from the environment. For the sustainable elimination of recalcitrant antibiotics, combined processes seem to be a more efficient and permanent solution for bypassing the toxicity of antibiotics.</p></div>","PeriodicalId":101255,"journal":{"name":"Total Environment Research Themes","volume":"3 ","pages":"Article 100008"},"PeriodicalIF":0.0,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2772809922000089/pdfft?md5=0da38c7b3c5e47d93e14d9cf036ad116&pid=1-s2.0-S2772809922000089-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90858536","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}
