Abstract:

Abstract Hospitals' effluents contain a considerable amount of chemicals. Considering the significant volume of wastewater discharged by hospitals, the presence of these chemicals represents a real threat to the environment and human health. Thus, the aim of this study was to evaluate the in vivo and in vitro genotoxicities of three wastewater effluents collected from Tunisian hospitals. The liver of Swiss albino male mice, previously treated with different doses of the hospital wastewaters, was used as a model to detect DNA fragmentation. Our results showed all the hospital effluents caused s

Abstract:

Untreated hospital effluent samples were tested for cytotoxic and genotoxicity in order to access whether they presented any serious health hazards. Results of umuC test suggested that the effluent from a large, general hospital could be considered weakly genotoxic. Comparatively, effluents from inpatient units presented higher frequency of genotoxicity than those coming from laboratory facilities. Although no cytotoxic activity was detected in laboratory effluent samples, cytotoxicity appeared to be an important problem of effluents from inpatient units.

Contamination of water resources by pathogenic microorganisms is a major concern worldwide. As an example, hospitals generate effluents with a wide range of chemical and microbiological contaminants. These effluents are generally not treated beforehand due to the high costs and are, therefore, mixed with domestic effluents in regional treatment systems. Thus, actions to maintain water quality include the development of appropriate materials for its sustainable treatment.

L’objectif de cette étude était d’étudier la qualité physico-chimique et toxicologique des effluents produits par les Centres Hospitaliers et Universitaires du département du Littoral. Il s’agissait d’une étude transversale descriptive et analytique sur 60 prélèvements d’effluents hospitaliers provenant des stations d’épuration et des fosses septiques. Les échantillons ont été prélevés dans des bouteilles en plastique de 1,5 litre. Les valeurs moyennes des paramètres avec leur

This study aims to isolate gram-negative bacteria (GNB) harboring the gene NDM-1 from the tertiary care hospital effluents. Also, aims to evaluate the relative copy number of blaNDM-1 carried by the positive isolates. The study isolated 215 GNB from 40 effluent samples. The antibiotic susceptibility tests for carbapenems were performed using disc diffusion assay. The isolates resistant to either meropenem or imipenem were checked for the existence of MBL by phenotypic methods. The isolates carrying NDM-1 gene were genotypically confirmed by Polymerase chain reaction (PCR). The gene copy number

Abstract Multi-drug resistance traits of Staphylococcus species especially methicillin-resistant Staphylococcus aureus (MRSA) in the clinical settings are well established. Of environmental concern is hospital effluents discharging into wastewaters. This article investigated the prevalence and detection of antibiotic resistance genes in Staphylococcus species from clinical and environmental sources in Ile-Ife, Nigeria. Standard culture-based and molecular protocols were used. Seventy-six (27 clinical, 14 hospital effluent and 35 environmental) Staphylococcus isolates were recovered: 56.58% wer

Wastewater samples from selected sites were collected, processed, and analysed presumptively by the culture dependent methods and molecular techniques. A total of 270 isolates were confirmed as Vibrio genus delineating into V. cholerae (27%), V. parahaemolyticus (9.1%), V. vulnificus (4.1%), and V. fluvialis (3%). The remainder (>50%) may account for other Vibrio species not identified in the study. The four Vibrio species were isola

Abstract:

The objective of this study was to characterize the wastewater from the BIAMBA Marie MUTOMBO hospital in terms of physico-chemical and bacteriological parameters, and to set up a pilot UASB reactor to treat this water. Two methods were used to conduct the investigations: observation and experimentation. Observations focused on wastewater management at the hospital and its surroundings, up to the point of discharge into the receiving environment. The analysis revealed that some parameters, such as COD, BOD5, turbidity, phosphorus, coliforms and fecal streptococci, exceeded discharge standards.

Abstract:

Hospitals are one of the key contributors of pharmaceutical contaminants of emerging concern to the sewer systems. Hospitals wastewaters contain concentrations of pharmaceutical compounds between 3 and 150, which are higher than urban wastewater streams. However, dedicated treatments of the hospital effluents before discharge to the sewer system are not compulsory. Besides, conventional wastewater treatment plants have not been designed to remove pharmaceutical compounds effectively, and consequently, these micropollutants can reach the aquatic ecosystems.
