“…Some studies have shown a correlation between antibiotics, ARGs, and antibiotic-resistant bacteria in hospital wastewaters ( Lira et al, 2020 ; Lutterbeck et al, 2020 ; Baraka et al, 2021 ). There were positive correlations between selected ARGs (sul1, sul2, tetQ, and qnrS) and the concentrations of certain antibiotics in the wastewaters of five hospitals in Xinjiang, China ( Li et al, 2016 ).…”

Controlling antibiotic resistance genes (ARGs) is a worldwide intervention to ensure global health. Hospital wastewater is the main pollution source of antibiotic-resistant bacteria and ARGs in the environment. Expanding our knowledge on the bacterial composition of hospital wastewater could help us to control infections in hospitals and decrease pathogen release into the environment. In this study, a high-throughput sequencing-based metagenomic approach was applied to investigate the community composition of bacteria and ARGs in untreated wastewater from three different types of hospitals [the general hospital, traditional Chinese medicine (TCM) hospital, and stomatology hospital]. In total, 130 phyla and 2,554 genera were identified from the microbiota of the wastewaters, with significantly different bacterial community compositions among the three hospitals. Total ARG analysis using the Antibiotic Resistance Genes Database (ARDB) and Comprehensive Antibiotic Resistance Database (CARD) revealed that the microbiota in the wastewaters from the three hospitals harbored different types and percentage of ARGs, and their composition was specific to the hospital type based on the correlation analysis between species and ARG abundance, some ARGs contributed to different bacterial genera with various relationships in different hospitals. In summary, our findings demonstrated a widespread occurrence of ARGs and ARG-harboring microbiota in untreated wastewaters of different hospitals, suggesting that protection measures should be applied to prevent human infections. Concurrently, hospital wastewater should be treated more specifically for the removal of pathogens before its discharge into the urban sewage system.

“…The effluents generated in hospital laundries present different characteristics from the others, due to the high volume of water and great complexity, such as the presence of different classes of surfactants and detergents, besides the high microbial and viral load, pharmaceuticals and common parameters in all the effluents (Kern et al, 2015 ; Lutterbeck, Colares, et al, 2020 ; Lutterbeck, Machado, et al, 2020 ; Zotesso et al, 2017 ). Table 4 presented the surfactant concentrations of studies conducted in countries such as France, Switzerland, and Turkey.…”

“…Table 4 presented the surfactant concentrations of studies conducted in countries such as France, Switzerland, and Turkey. In the survey conducted by Lutterbeck, Machado, et al ( 2020 ), Lutterbeck, Colares, et al ( 2020 ), treatment processes and toxicity of influents and effluents from the laundry of a 180-bed hospital, which generates 150 m 3 of effluent daily, were evaluated. Of this volume, 33% is produced in the hospital laundry.…”

“…The acute ecotoxicity tests, with Daphnia magna , revealed, for the raw effluent, extreme toxicity (EC50 24.5%). After undergoing effluent treatments, a 100% EC50 was obtained, indicating non-toxicity (Lutterbeck, Colares, et al, 2020 ; Lutterbeck, Machado, et al, 2020 ). In 2015, Kern and collaborators also analyzed the laundry effluent from the same hospital and identified the following surfactants: lauryl ethoxylate, benzoic acid, n-(4-aminophenyl)-n-methylacetamide, 2-(diethylamino)-n-(2,6-dimethylphenyl)-acetamide), and methyl-m-(1-methylbutyl) phenyl ester, by gas chromatography.…”

Surfactants are substances that when in aquatic environments can cause negative impacts. Hospital effluents carry numerous chemicals daily, including surfactants, used in sanitization and disinfection procedures. These chemicals are found in the effluents and reach water bodies due to a lack of proper removal in the wastewater treatment plants. The present study investigated data about wastewater monitored from healthcare facilities located in the city of Belo Horizonte, Brazil, focusing on anionic surfactants. The results showed 72 establishments monitoring this parameter, resulting in a median concentration of 1 mg L −1 and 2.49 mg L −1 mean value of anionic surfactants, between 2007 and 2019. It is also observed in the correlation between surfactants and oils in all healthcare establishment sizes, except for the medium-sized. Although anionic surfactants are the most used in cleaning product formulations, cationic surfactants still do not have specific legislation in the studied country that dictates a limit for discharge into sewage; consequently, they are not routinely monitored in effluents. However, these compounds are used in the formulation of routine hospital products.

“…The discharge of these effluents in the urban sewer networks or into the natural environment can generate risks for human health. These effluents represent also a significant contribution to the general contamination of the environment [6][7][8][9]. Chemical residues are toxic environmental pollutants and are the most highly bio-concentrated trace metals [8].…”
