Summary

Scientists used nanoscale imaging to show that nanoplastics coated with glyphosate herbicide can become trapped within soil mineral surfaces through crystal growth and particle aggregation. This trapping mechanism may limit how far nanoplastics and their associated chemicals migrate through soil toward groundwater.

Functional nanoplastics (PSFG) complexed with glyphosate (PMG) are occluded within the model minerals calcite and iron hydroxide through growing hillocks and particle aggregation, respectively, thus limiting their soil migration and plant uptake.
