Abstract

Nanoplastics (NPs) and plastic additives inevitably coexist to threaten soil health and plant growth. Herein, in a root-box system isolating the rhizosphere and bulk soils, we explored the combined effects of NPs and a kind of typical plastic additive di-(2-ethylhexyl)phthalate (DEHP) on soil health via combining the evidence from in situ zymography, the microbiome, and metabolism. The plastic additive dominated the risks of plastic pollution to plants, and the coexistence of NPs did not mitigate the DEHP threat to microorganisms and increased that to food safety. Compared to single DEHP, combined NPs and DEHP inhibited β-glucosidase activity to limit soil organic carbon (C) decomposition and stimulated acid phosphatase activity to increase P uptake by tomato roots and enriched the relative abundance of C-fixed bacteria and P-dissolution bacteria, while inhibiting that of chemical heterotrophic bacteria in rhizosphere soils, which further stimulated the synthesis and metabolism of phospholipid and fatty acid and triphosphate cycle and increased nutrients bioavailability for plants. Therefore, rhizosphere effects optimized the root nutrient acquisition strategy, microbial community structure, and their metabolic processes to reduce the threat from NPs and plastic additives to plants. This study provides new insights for environmental risk control and agricultural management under plastic pollution.

根际效应能否减轻纳米塑料和塑料添加剂对番茄的威胁?
纳米塑料与塑料添加剂不可避免地共存,对土壤健康和植物生长造成威胁。本研究在分离根际和土壤的根箱系统中,通过结合原位酶谱、微生物组和代谢的证据,探讨了NPs和一种典型的塑料添加剂邻苯二甲酸二(2-乙基己基)酯(DEHP)对土壤健康的联合影响。塑料添加剂对植物的塑料污染风险占主导地位,NPs的共存并没有减轻DEHP对微生物的威胁,反而增加了对食品安全的威胁。与单一DEHP相比,NPs和DEHP联合施用抑制β-葡萄糖苷酶活性,限制土壤有机碳(C)分解,刺激酸性磷酸酶活性,增加番茄根系对P的吸收,提高根际土壤中固定C细菌和溶解P细菌的相对丰度,抑制化学异养细菌的相对丰度。这进一步刺激了磷脂和脂肪酸的合成和代谢,促进了三磷酸循环,提高了植物营养物质的生物利用度。因此,根际效应优化了根系养分获取策略、微生物群落结构及其代谢过程,降低了NPs和塑料添加剂对植物的威胁。本研究为塑料污染下的环境风险控制和农业管理提供了新的思路。
