Tomography with neutrons and X-rays shows where particles are deposited

A sample of Beelitz sandy soil containing fragments of thin polyethylene film (PET) was analyzed here. Such films are used in asparagus cultivation. The neutron tomography (in shades of gray) shows where the PET fragments are located. X-ray tomography of the sample (ochre) reveals the soil structure: superimposed on the neutron tomography, the PET particles (in blue) contained therein become visible. Credit: C.

It is a real problem: Microplastic particles are…
