Summary

Researchers studied how environmentally realistic levels of microplastics affect the growth and stress responses of edible crops. The study found that microplastics disrupt plant growth and stress pathways through mechanisms that vary by crop species. These findings highlight the importance of understanding how different plants interact with microplastic particles when assessing risks to agricultural food production.

These findings support current ecotoxicological models and highlight the importance of plant-particle interactions in shaping crop responses. The results provide new insight into MP phytotoxicity and inform future risk assessments under realistic soil conditions.
