Development and validation of a low-cost modular in-line filtration apparatus for high-volume microplastic sampling in groundwater wells
Researchers designed a low-cost (~$120) all-metal filtration system to collect microplastics from groundwater wells, capable of filtering over 500 liters per well with up to 96% particle recovery. The device addresses a major gap in monitoring — most microplastic sampling tools are too expensive or plastic-contaminated to work reliably in groundwater.

A new encapsulated filtration device was developed for sampling small microplastics (in the lower micrometer size range) from water, reducing contamination and sample loss compared to standard net methods. Capturing very small microplastics is important because this size range is particularly abundant and potentially most harmful.

Isokinetic pump sampling – first application results and contribution of smallest microplastic fractions to riverine transport
Scientists developed a new way to detect the tiniest plastic particles in rivers that older methods couldn't catch. They found these ultra-small microplastics make up a surprisingly large portion of all plastic pollution flowing through waterways. This matters because these tiny particles are more likely to travel long distances and potentially end up in our drinking water and food supply.
