Antimicrobial resistance landscape in a metropolitan city context using open drain wastewater-based metagenomic analysis
Environ Res. 2024 Mar 17:118556. doi: 10.1016/j.envres.2024.118556. Online ahead of print.ABSTRACTOne Health concept recognizes the inextricable interactions of diverse ecosystems and their subsequent effect on human, animal and plant health. Antimicrobial resistance (AMR) is a major One Health concern and is predicted to cause catastrophes if appropriate measures are not implemented. To understand the AMR landscape in a south Indian metropolitan city, metagenomic analysis of open drains was performed. The data suggests that in January 2022, macrolide class of antibiotics contributed the highest resistance of 40.1% in the ...

Anti-inflammatory, anti-diabetic, and biocompatibility properties of aqueous extract of Tamarindus indica L. fruit coat analyses by in-vitro and in-vivo approaches
Environ Res. 2024 Mar 19;251(Pt 2):118702. doi: 10.1016/j.envres.2024.118702. Online ahead of print.ABSTRACTThe anti-inflammatory, anti-diabetic, and biocompatibility nature of Tamarindus indica L. fruit coat aqueous extract were investigated in this research through in-vitro and in-vivo studies. The anti-inflammatory property was determined through albumin denaturation inhibition and antiprotease activities as up to 39.5% and 41.2% respectively at 30 mg mL-1 concentration. Furthermore, the antidiabetic activity was determined through α-amylase and α-glucosidase inhibition as up to 62.15% and 67.35% respectively at 30 mg...

Investigating the characteristics of combustible fraction of legacy waste: A study on energy recovery potential and GHG emission quantification
Environ Res. 2024 Mar 16:118669. doi: 10.1016/j.envres.2024.118669. Online ahead of print.ABSTRACTIn India, majority of the generated municipal solid waste (MSW) was dumped in poorly managed landfills and dumpsites over the past decades and is an environmental and health hazard. Landfill mining is a promising solution to reclaim these sites along with the recovery of resources (materials and energy). During landfill mining operations, the combustible fraction is one of the major components recovered and needs proper management for maximizing resource recovery. For the identification of appropriate resource recovery options...

Valorization of treated swine wastewater and generated biomass by microalgae: Their effects and salt tolerance mechanisms on wheat seedling growth
In this study, a step-by-step resource utilization study of algae-containing wastewater generated from microalgae treatment of swine wastewater was carried out. When wheat seedlings were cultivated in the effluent after microalgae separation, the root fresh weight, seedling fresh weight, and total seedling length were increased by 3.44%, 14.45%, and 13.64%, respectively, compared with that of the algae-containing wastewater, and there was no significant difference in seedling fresh weight, total seedling length, maximum quantum yields of PSII photochemistry (Fv/Fm), and performance index (PIABS) from that of the Hogland so...

Enrichment performance and salt tolerance of polyhydroxyalkanoates (PHAs) producing mixed cultures under different saline environments
In this study, three kinds of activated sludge from different salinity environments were selected as the inoculum to enrich salt-tolerant PHA producers under aerobic dynamic feeding (ADF) mode with butyric acid dominated mixed volatile fatty acid as the substrate. The maximum PHA content (PHAm) reached 0.62 ± 0.01, 0.62 ± 0.02, and 0.55 ± 0.03 g PHA/g VSS at salinity of 0.5%, 0.8%, and 1.8%, respectively. Microbial community analysis indicated that Thauera, Paracoccus, and Prosthecobacter were dominant salt-tolerant PHA producers at low salinity, Thauera, NS9_marine, and SM1A02 were dominant salt-tolerant PHA producers ...

Electric vehicles and health: A scoping review
CONCLUSIONS: The results of the current literature on electric vehicles and health suggest an overall positive health impact of transitioning to electric vehicles. Additional observational studies would help expand our understanding of the real-world health effects of electric vehicles. Future research focused on the environmental justice implications of vehicle fleet transitions could provide additional information about the extent to which the health benefits occur equitably across populations.PMID:38499224 | DOI:10.1016/j.envres.2024.118697 (Source: Environmental Research)

Norfloxacin adsorption by torrefied coco peat biochar as a novel adsorbent in a circular economy framework
Environ Res. 2024 Mar 17;251(Pt 2):118711. doi: 10.1016/j.envres.2024.118711. Online ahead of print.ABSTRACTThe current study reported torrefied coco-peat biochar treated at 200 °C, as a novel adsorbent exhibiting phenomenal norfloxacin (NFX) adsorption efficiency. The CHNS analysis confirmed the carbon abundance in the biochar (36.45%), however, XRF analysis indicated a significant presence of K2O (27.73%) and chlorine (7.49%). The XRD and Raman spectral analysis confirmed the amorphous structure of the biochar. Multilayer topology was evident in the SEM micrograph of biochar contributing to its large effective surface a...
