Environmental contaminants, such as heavy metals, nanomaterials, and pesticides, induce the formation of reactive oxygen and nitrogen species (RONS). Plants interact closely with the atmosphere, water, and soil, and consequently RONS intensely affect their biochemistry. For the past 30 years researchers have thoroughly examined the role of RONS in plant organisms and oxidative modifications to cellular components. Hydrogen peroxide, superoxide anion, nitrogen(II) oxide, and hydroxyl radicals have been found to take part in many metabolic pathways. In this review the various aspects of the oxidative stress induced by environmental contamination are described based on an analysis of literature. The review reinforces the contention that RONS play a dual role, that is, both a deleterious and a beneficial one, in plants. Environmental contamination affects human health, also, and so we have additionally described the impact of RONS on the coupled human - environment system.
环境污染物，如重金属、纳米材料和农药，会诱导活性氧和氮物种 (RONS) 的形成。植物与大气、水和土壤密切相互作用，因此 RONS 会强烈影响它们的生物化学。在过去的 30 年中，研究人员已经彻底研究了 RONS 在植物生物中的作用以及对细胞成分的氧化修饰。已经发现过氧化氢、超氧阴离子、一氧化氮(II)和羟基自由基参与了许多代谢途径。在本综述中，基于对文献的分析，描述了环境污染引起的氧化应激的各个方面。该综述强调了 RONS 在植物中既具有有害作用又具有有益作用的双重作用。环境污染也会影响人类健康，因此我们还描述了 RONS 对人类-环境耦合系统的影响。
