Morphological Rather Than Abundance Factors Control Microplastic Accumulation in Wheat Grains: A Field-Based Study.

Key Points

• The study aims to explore the influence of microplastic morphology on its accumulation in wheat grains and plant uptake mechanisms.
• Conducted a field-based study analyzing the accumulation of microplastics in wheat grains.
• Examined the relationship between microplastic shape and absorption by the plants.
• Identified key factors influencing microplastic uptake through detailed morphological assessment.
• Findings reveal that microplastic shape significantly influences its absorption in wheat grains.
• Fibrous polystyrene reduced uptake efficiency compared to other shapes, impacting overall accumulation.
• Reported a significant correlation between microplastic morphology and plant uptake metrics.
