Improving Microspectroscopic Microplastic Data Extrapolation: From Field of View to Full Sample, and from Fragment 2D-Morphology to Mass

Microplastics
Microplastic (MP) analysis via microspectroscopy typically examines only 1–10% of filter substrates due to time constraints, requiring reliable extrapolation methods for quantitative environmental monitoring.

Microplastic diversity increases the abundance of antibiotic resistance genes in soil

Nature Communications
The impact of microplastics on antibiotic resistance has attracted widespread attention. However, previous studies primarily focused on the effects of individual microplastics.

Seafloor microplastic hotspots controlled by deep-sea circulation

Science, 2020
Not just settling What controls the distribution of microplastics on the deep seafloor? Kane et al. show that the answer to that question is more complicated than particles simply settling from where they are found on the sea surface (see the Perspective

Agricultural fertilisers contribute substantially to microplastic concentrations in UK soils

Communications Earth & Environment
Since their invention, plastics have driven a revolution in behavior in all aspects of our lives, including agriculture. In-use and as a waste material, plastics degrade and accumulate in agricultural systems.
