The outburst of plastic pollution in terrestrial ecosystems poses a potential threat to agriculture and food safety. Studies have already provided evidence for the uptake of plastic microparticles by several plant species, accompanied by numerous developmental effects, using fluorescence labelling techniques. Here, we introduce the implementation of confocal Raman spectroscopy, a label-free method, for the effective detection of microplastics (MPs) accumulation in the roots of a common edible root vegetable plant, , after treatment with acrylonitrile butadiene styrene (ABS) powder. We also demonstrate the concomitant occurrence of phenotypic defects in the polymer-treated plants. We anticipate that this work can provide new insights not only into the extent of the impact this widespread phenomenon has on crop plants but also on the methodological requirements to address it.
陆地生态系统中塑料污染的爆发对农业和食品安全构成了潜在威胁。利用荧光标记技术，已有研究证明几种植物物种能够吸收塑料微粒，并伴随着许多发育效应。在此，我们介绍了共聚焦拉曼光谱法的应用，这是一种无需标记的方法，用于有效检测常见可食用块根蔬菜植物在用丙烯腈丁二烯苯乙烯（ABS）粉末处理后根部微塑料（MPs）的积累情况。我们还证明了在聚合物处理的植物中同时出现了表型缺陷。我们预计这项工作不仅可以为这一普遍现象对农作物的影响程度提供新的见解，还可以为解决这一问题的方法学要求提供新的见解。
