A comparative analysis of the partitioning behaviour of SARS-CoV-2 RNA in liquid and solid fractions of wastewater.

As fragments of SARS-CoV-2 RNA can be quantified and measured temporally in wastewater, surveillance of concentrations of SARS-CoV-2 in wastewater has become a vital resource for tracking the spread of COVID-19 in and among communities. However, the absence of standardized methods has affected the interpretation of data for public health efforts. In particular, analyzing either the liquid or solid fraction has implications for the interpretation of how viral RNA is quantified.

Photodecomposition of pharmaceuticals and personal care products using P25 modified with Ag nanoparticles in the presence of natural organic matter.

The presence of pharmaceuticals and personal care products (PPCPs) in water remains a concern due to their potential threat to environmental and human health. Advanced oxidation processes (AOPs) have been receiving attention in water treatment studies to remove PPCPs. However, most studies have been focused on pure water containing a limited number of substances.
