Brazilian group presents novel method of analyzing microplastic pollution

Envirotec Magazine

The last decade has seen some progress with studying plastic pollution, but there are still significant challenges, such as a lack of comparability of reported results, especially when it comes to microplastic particles. Few studies of pollution by MPs have been published in Brazil, especially regarding inland aquatic areas.

Tannins: A possible answer to microplastic pollution?

Envirotec Magazine

Scientists at UBC’s BioProducts Institute find that if you add tannins to a layer of wood dust, you can create a filter that traps virtually all microplastic particles present in water, according to recently reported research. per cent of plastic particles in a column of water, depending on plastic type. per cent to 99.9

Survey identifies significant micro plastic pollution on summit of Snowdon

Envirotec Magazine

Geoscience technology firm CGG has conducted a microplastics pollution survey as part of a scoping study into whether it would be possible to create a “Plastic Free zone” on Yr Wyddfa (Snowdon). This workflow can be used to calculate the volume, size and shape of plastic particles within a sample.

Retention ponds can reduce tyre particle pollution

Envirotec Magazine

The study also found that tyre wear particles significantly outweighed other forms of microplastics, such as plastic fibres and fragments, in the samples collected but that they were also removed in far greater quantities. Easy come, easy go? It was funded by UK National Highways.

Using microbes to remove microplastics

Envirotec Magazine

Researchers at Hong Kong Polytechnic University have developed a seemingly new technique to trap and recover microplastics. The method uses bacterial biofilms, a sticky substance created by micro-organisms, to trap microplastic particles. In bioreactors, this makes the microplastics more convenient to collect, according to Liu.

LDIR microplastic analysis used in the Indian Ocean

Envirotec Magazine

Methods for the analysis of microplastic particles in a sample (of water) are beset by challenges such as high error rates and a high time requirement. The chemical characterization of the microplastic particles is based on their absorption of infrared light. Near-surface analysis.

Natural clean-up: Bacteria can remove plastic pollution from lakes

Envirotec Magazine

A study of 29 European lakes has found that some naturally-occurring lake bacteria grow faster and more efficiently on the remains of plastic bags than on natural matter like leaves and twigs. The bacteria break down the carbon compounds in plastic to use as food for their growth.
