Virus Log Reduction Values and Dominant Mechanisms in Full-Scale Secondary Biological Wastewater Treatment Systems. [PDF]

open access: yesWater Environ Res
For secondary treatment, the dominant virus removal mechanism varies based on system type and method(s) used to quantify virus reduction. This study demonstrates that secondary treatment can achieve significant virus reduction, but regulatory crediting for direct potable reuse may still not be justified.

Comparison of UV‐Cl and UV‐H2O2 advanced oxidation processes in the degradation of contaminants from water and wastewater: A review

open access: yesWater and Environment Journal, Volume 37, Issue 4, Page 633-643, November 2023., 2023
Abstract Applications of advanced oxidation processes (AOPs) in water and wastewater treatment have been the subject of growing interest throughout the last decade. Although UV/hydrogen peroxide (UV‐H2O2) is the most established technology among the UV‐AOPs, UV‐chlorine (UV‐Cl) is emerging as a reliable and potentially more cost‐effective alternative ...

Microbiological hazards associated with the use of water in the post‐harvest handling and processing operations of fresh and frozen fruits, vegetables and herbs (ffFVHs). Part 1 (outbreak data analysis, literature review and stakeholder questionnaire)

open access: yesEFSA Journal, Volume 21, Issue 11, November 2023., 2023
Abstract The contamination of water used in post‐harvest handling and processing operations of fresh and frozen fruit, vegetables and herbs (ffFVHs) is a global concern. The most relevant microbial hazards associated with this water are: Listeria monocytogenes, Salmonella spp., human pathogenic Escherichia coli and enteric viruses, which have been ...

Sample and library preparation approaches for the analysis of the virome of irrigation water

open access: yesJournal of the Science of Food and Agriculture, Volume 103, Issue 9, Page 4450-4457, July 2023., 2023
Abstract BACKGROUND The virome (i.e. community of mainly RNA and DNA eukaryotic viruses and bacteriophages) of waters is yet to be extensively explored. In particular, the virome of waters used for irrigation could therefore potentially carry viral pathogens that can contaminate fresh produce.

The temporal expression of circulating microRNAs after acute experimental pain in humans

open access: yesEuropean Journal of Pain, Volume 27, Issue 3, Page 366-377, March 2023., 2023
Abstract Background MicroRNAs (miRNAs) can modulate several biological systems, including the pain system. This study aimed to evaluate the temporal expression of circulating miRNAs in the plasma of healthy volunteers as a marker for epigenetic changes before and after an acute, experimental, pain provocation by intramuscular hypertonic saline ...

Somatic coliphages as surrogates for enteroviruses in sludge hygienization treatments

open access: yesWater Science and Technology, 2016
Conventional bacterial indicators present serious drawbacks giving information about viral pathogens persistence during sludge hygienization treatments. This calls for the search of alternative viral indicators. Somatic coliphages’ (SOMCPH) ability for acting as surrogates for enteroviruses was assessed in 47 sludge samples subjected to novel treatment
