Degradation of cellulose-based wet wipes marketed as ‘biodegradable’ in their receiving urban rivers Open
The environmental degradation and fate of cellulose-based 'biodegradable' wet wipes under real-world conditions remain underexplored, particularly in urban freshwater systems where they are frequently discharged via toilet flushing. Buildi…

Cellulose-based wet wipes undergo limited degradation in river environments Open
The environmental fate of cellulose-based "biodegradable" wet wipes in freshwater ecosystems remains poorly understood, despite growing market demand and legislative shifts banning plastic-containing alternatives. This study evaluated the …

Toxicity of the water-soluble polymer PVP is dependent on molecular weight and feed concentration for a freshwater model species Open
Polyvinylpyrrolidone (PVP) is a synthetic water-soluble polymer (WSP) that does not readily biodegrade and has been detected in rivers in the mg L-1 range. Whilst previous studies have highlighted sublethal impacts of this chemi…

In Situ Polymerization of Barium Hexaferrite Ferrofluids for Poly(Ethylene) Succinate Magnetic Nanoparticle Composites Open
The integration of hard magnetic barium hexaferrite (BHF) nanoplatelets into a dense poly(ethylene succinate) (PES) polyester matrix produces an exciting biodegradable thermoplastic magnetic polymer nanocomposite. In this work, scandium‐su…

Is there a trend in inductive effect for different alkyl groups? Open
We find there to be no significant difference between the inductive effects of four representative alkyl groups as determined by Hirshfeld charge analysis.

Assessing the chemical interactions and biological effects of a petrochemical and bio-based plastic with a common plastic flame retardant and solvent Open
Microplastic pollution remains a persistent environmental challenge for aquatic environments. Yet, health impact assessments of microplastics focus largely on the polymers themselves. It is important to understand the chemical behaviour an…

Alkyl groups in organic molecules are NOT inductively electron-releasing Open
Contrary to their presentation in almost all organic chemistry textbooks, analysis of calculated charges shows alkyl groups to be inductively electron-withdrawing compared to hydrogen. We find no compelling evidence for the textbook positi…

Predicting flushed wet wipe emissions into rivers Open
Flushed wet wipes pose a significant pollution risk to river systems at both macro and micro levels. However, the link between their emissions and environmental contamination remains unclear. Here we integrated emissions-based modelling wi…
