Summary

Researchers found that "biodegradable" plastic particles in soil can actually harm cucumber seedlings by disrupting soil nutrients — with one type (called PCL) causing the most damage. This matters because it suggests that switching to biodegradable plastics isn't automatically a safe fix for plastic pollution, and it raises questions about how microplastics in farm soil could affect the food crops we eat.

<0.05). In conclusion, biodegradable MPs could reduce cucumber seedling growth by affecting the soil and nutrient status, and the negative impact of 2% PCL MPs on cucumber seedling growth and soil nutrients was most significant. The findings of this study lay the groundwork for the prevention and control of microplastic pollution and impacts on plant health.
