The missing small microplastics: easily generated from weathered plastic pieces in labs but hardly detected in natural environments

Plentiful small microplastics and nanoplastics can easily generate from weathered plastics, but few small microplastics and no nanoplatics could be detected in surrounding sediments, possibly due to a lack of suitable detection approach.

Characterization and quantification of microplastics and organic pollutants in mussels by microwave-assisted sample preparation and analytical pyrolysis

We developed a method to isolate and quantify various classes of both non-polymeric contaminants and polymers from mussel flour using microwave-assisted extraction/digestion and analytical pyrolysis-GC-MS.

About this collection

The term ‘chemicals of emerging concern’ refers to substances where there is a rising concern about their danger to both the environment and human health. Many of these have only recently been identified as a risk and so have not been regulated under national or international legislation. These chemicals can include micro/nano plastics, antibiotics, drugs, hormones and industrial additives. Therefore, early warning methods for these emerging chemicals which can reduce disaster risks are of paramount importance, with clear implications for policy.

This collection aims to highlight important emerging pollutants, and increase our understanding of their transport, fate, and behaviour in the environment, as well as highlighting ‘early warning’ methods, and inspire future work in this area.
