TL;DR: This is the first comprehensive study which demonstrates an alarming usage and emission of various antibiotics in China and the bacterial resistance rates in the hospitals and aquatic environments were found to be related to the PECs and antibiotic usages, especially for those antibiotics used in the most recent period.
Abstract: Antibiotics are widely used in humans and animals, but there is a big concern about their negative impacts on ecosystem and human health after use. So far there is a lack of information on emission inventory and environmental fate of antibiotics in China. We studied national consumption, emissions, and multimedia fate of 36 frequently detected antibiotics in China by market survey, data analysis, and level III fugacity modeling tools. Based on our survey, the total usage for the 36 chemicals was 92700 tons in 2013, an estimated 54000 tons of the antibiotics was excreted by human and animals, and eventually 53800 tons of them entered into the receiving environment following various wastewater treatments. The fugacity model successfully predicted environmental concentrations (PECs) in all 58 river basins of China, which are comparable to the reported measured environmental concentrations (MECs) available in some basins. The bacterial resistance rates in the hospitals and aquatic environments were found to b...

TL;DR: It is important to understand the current state of antibiotic use in China and its relationship to ARG prevalence and diversity in the environment, and also future needs in mitigating the spread of antibiotic resistance in the environments, particularly under the 'planetary health' perspective.

TL;DR: In this paper, the authors collected information from several investigations on the sources and occurrences of antibiotics in natural and artificial environmental systems, including water resources, effluent from industries, sludge, manure, soil, plants, and organisms across the globe.
Abstract: Antibiotics have been extensively and effectively used in human and veterinary medicines. Their benefits have been recognized in agriculture, aquaculture, bee-keeping, and livestock as growth promoters. This paper collects information from several investigations on the sources and occurrences of antibiotics in natural and artificial environmental systems. Several antibiotics were reported for their occurrences in water resources, effluent from industries, sludge, manure, soil, plants, and organisms across the globe. Sorption, photo-degradation, biodegradation, and oxidation were recognized as the main elimination pathways for these compounds and have been discussed in detail. The adverse effects of the pollutants were also highlighted and necessary suggestions were made for effective monitoring and mitigating pollution, which may provide the scope for future research.

TL;DR: This review systematically summarizes the behavior and removal of different antibiotics in various biological treatment systems with discussion on their removal efficiency, removal mechanisms, critical bioreactor operating conditions affecting antibiotics removal, and recent innovative advancements.
Abstract: Antibiotics, the most frequently prescribed drugs of modern medicine, are extensively used for both human and veterinary applications. Antibiotics from different wastewater sources (e.g., municipal, hospitals, animal production, and pharmaceutical industries) ultimately are discharged into wastewater treatment plants. Sorption and biodegradation are the two major removal pathways of antibiotics during biological wastewater treatment processes. This review provides the fundamental insights into sorption mechanisms and biodegradation pathways of different classes of antibiotics with diverse physical-chemical attributes. Important factors affecting sorption and biodegradation behavior of antibiotics are also highlighted. Furthermore, this review also sheds light on the critical role of extracellular polymeric substances on antibiotics adsorption and their removal in engineered biological wastewater treatment systems. Despite major advancements, engineered biological wastewater treatment systems are only moderately effective (48-77%) in the removal of antibiotics. In this review, we systematically summarize the behavior and removal of different antibiotics in various biological treatment systems with discussion on their removal efficiency, removal mechanisms, critical bioreactor operating conditions affecting antibiotics removal, and recent innovative advancements. Besides, relevant background information including antibiotics classification, physical-chemical properties, and their occurrence in the environment from different sources is also briefly covered. This review aims to advance our understanding of the fate of various classes of antibiotics in engineered biological wastewater treatment systems and outlines future research directions.
