    Shedding light on the impact of microplastics on lentil seedling growth

    Microplastic pollution is known to negatively impact seed germination and seedling growth. Although some studies have demonstrated the effects of microplastics on seed germination, the impact of microplastics on the internal biological activity of seeds remained unknown. Now, a group of researchers has used biospeckle optical coherence tomography to reveal that microplastics significantly hinder the internal activity in lentil seeds during germination and can lead to stunted growth at later stages.

    1. Our findings showed, for the first time, that microplastics impede the internal activity of seeds during germination. This is likely due to the physical blockage of pores, which leads to stunted growth at later stages.
    2. Our results highlight the potential of bOCT as a screening tool for a speedy assessment of seed quality and environmental pollution.
