Abstract

The rise of airborne micro-nanoplastics (MNPs) pollution poses a significant threat to agroecological systems. Despite this issue, there is a critical gap in our understanding of their specific effects on various leafy vegetable species. To address this, we conducted a controlled experiment applying Polystyrene Nanoplastics (PS-NPs) on four leafy vegetables: Brassica rapa var. chinensis, B. rapa var. parachinensis, Amaranthus viridis, and Allium tuberosum. Our results showed that PS-NPs tend to accumulate within the epidermal layers and cuticles of these vegetables, particularly around stomatal apertures. More PS-NPs were found on the adaxial and abaxial side of leaves, compared to the cross-section. The abundance of PS-NPs accumulations varied significantly among the studied species due to differences in leaf structure. Notably, leaves with trichomes trapped more PS-NPs particles. These accumulation significantly reduced chlorophyll content and photosynthetic rates, altering the growth and nutritional quality of the vegetables. Our findings reveal the ecological effects of PS-NPs on the nutrient content, phenotype, physiology, growth and biomass metrics of common leafy vegetables. This highlights the potential for PS-NPs accumulation in edible plant tissues, raising concerns about food security and human health.

聚苯乙烯纳米塑料对叶菜类的叶面影响及其生态后果
空气中微纳米塑料(MNPs)污染的增加对农业生态系统构成了重大威胁。尽管存在这一问题,但我们对其对各种叶菜品种的具体影响的了解还存在重大差距。为了解决这个问题,我们进行了一项对照实验,在四种叶菜中施用聚苯乙烯纳米塑料(PS-NPs):chinensis、B. rapa var.parachinensis、Amaranthus viridis 和 Allium tuberosum。我们的研究结果表明,PS-NPs 往往积聚在这些蔬菜的表皮层和角质层中,尤其是在气孔周围。与横截面相比,在叶片的正面和背面发现了更多的 PS-NPs。由于叶片结构的不同,PS-NPs 在不同研究物种中的累积量也有很大差异。值得注意的是,带有毛状体的叶片捕获了更多的 PS-NPs 颗粒。这些积累大大降低了叶绿素含量和光合速率,改变了蔬菜的生长和营养质量。我们的研究结果揭示了 PS-NPs 对常见叶菜营养成分、表型、生理、生长和生物量指标的生态影响。这凸显了 PS-NPs 在可食用植物组织中积累的潜力,引起了人们对食品安全和人类健康的关注。

期刊介绍: The Journal of Hazardous Materials serves as a global platform for promoting cutting-edge research in the field of Environmental Science and Engineering. Our publication features a wide range of articles, including full-length research papers, review articles, and perspectives, with the aim of enhancing our understanding of the dangers and risks associated with various materials concerning public health and the environment. It is important to note that the term "environmental contaminants" refers specifically to substances that pose hazardous effects through contamination, while excluding those that do not have such impacts on the environment or human health. Moreover, we emphasize the distinction between wastes and hazardous materials in order to provide further clarity on the scope of the journal. We have a keen interest in exploring specific compounds and microbial agents that have adverse effects on the environment.
