Microplastics (MPs) in aquatic environments easily support biofilm development, which can interact with other environmental pollutants and act as harbors for microorganisms. Recently, numerous studies have investigated the fate behavior of MP biofilms environments, highlighting their roles spread pathogens antibiotic resistance genes (ARGs) to organisms new habitats. The prevalence effects been extensively recent decades, behaviors need be synthesized systematically updated information. This review aims reveal development its interactions antibiotics, ARGs, environments. Recent research has shown that adsorption capabilities MPs antibiotics are enhanced after formation, is biased towards chemisorption. ARGs microorganisms, especially pathogens, selectively enriched significantly different from those surrounding waters. promotes propagation through horizontal gene transfer (HGT) vertical (VGT) induces emergence antibiotic-resistant resulting increased threats ecosystems human health.

Removal of microplastic particles during municipal wastewater treatment: A current review

Desalination and Water Treatment, Journal Year: 2024, Volume and Issue: 317, P. 100006 - 100006

Published: Jan. 1, 2024

Wastewater treatment plants (WWTPs) are considered the main point source of microplastics (MPs) discharged into water bodies. The article discusses types and number MPs present in wastewater effectiveness their removal at municipal WWTP. use different methodologies for determining makes it difficult to compare results obtained studies authors. Limitations various sampling, preparation final identification techniques MPs, that may lead over or underestimating wastewater, were indicated. Although efficiency on WWPP is reaching 98% more with advanced treatment, large WWTP could as much 1010 MPs/day. These values often do not take account particles smaller than 1 µm (nanoplastics), which effluent can be significant. degradation products have a harmful effect environment, therefore increasing from very important. This achieved by introducing additional purification processes, well improving operation existing ones.

Extraction and analytical methods of microplastics in wastewater treatment plants: Isolation patterns, quantification, and size characterization techniques

Desalination and Water Treatment, Journal Year: 2024, Volume and Issue: 318, P. 100399 - 100399

Published: April 1, 2024

Microplastics are pollutants formed from fragmented plastics and also industrially manufactured for personal care cosmetic products. They range 1 µm to 5 mm ubiquitous in the environment due their tiny size, lightweight, wide applications. Ecotoxicological studies have shown that they can induce multiple harmful effects on exposed organisms humans. Wastewater treatment plants (WWTPs) drawn interest of researchers regulatory bodies worldwide as a point source microplastics discharge environment. In absence standardized methodology, microplastic monitoring WWTPs has been marked by distinct variations sample processing analytical procedures which limit comparison results. This review provides detailed analysis methods patterns, analytical, size characterization, quantification WWTPs. According procedural steps extraction reported reviewed studies, 12 patterns three categories approaches (single, dual, multiple) were identified. quantified using gravimetry method, mass sub-sample method (based extrapolation) with latter being most applied technique. Microplastic characterization accomplished two main methods: sieve-based technique computing-based

Evaluation of the physicochemical and bacteriological quality of groundwater in the Nihit rural commune of the Moroccan Anti-Atlas

Desalination and Water Treatment, Journal Year: 2024, Volume and Issue: 317, P. 100038 - 100038

Published: Jan. 1, 2024

Our study evaluated the physico-chemical and bacteriological quality of water wells boreholes in rural commune Nihit Moroccan Anti Atlas. In this study, we assessed qualities such as pH, temperature, conductivity, turbidity, nitrate, nitrite, sulfate, mineral elements, heavy metals. We also studied terms microbial germs represented by Total Coliforms, Fecal Escherichia coli (E. coli), Intestinal Enterococci, sulfito-reducing Clostridium. Apart from two points located upstream Douars, nitrate concentrations range 60 to 290 mg.L-1, well above permissible value according World Health Organization (50 mg.L-1). At some points, values reach 4.1.103 CFU/100 mL, 1.9.102 1.8.103 90 respectively for total coliforms, fecal Escherichia, intestinal enterococci The presence E. tested is an indicator contamination human or animal matter, which may come conventional septic tanks, untreated wastewater discharges, manure leaching, runoff. On other hand, physicochemical parameters remain compliant with potable standards.
