Zinc oxide nanoparticles (ZnO NPs) have a wide range of applications in cosmetics, electrical, and optical industries. The wide range of applications of ZnO NPs, especially in personal care products, suggest they can reach major environmental matrices causing unforeseen effects. Recent literature has shown conflicting findings regarding the beneficial or detrimental effects of ZnO NPs towards terrestrial biota. In this review we carried out a comprehensive survey about beneficial, as well as detrimental aspects, of the ZnO NPs exposure toward various terrestrial plants. A careful scrutiny of the literature indicates that at low concentrations (about 50 mg/kg), ZnO NPs have beneficial effects on plants. Conversely, at concentrations above 500 mg/kg they may have detrimental effects, unless there is a deficiency of Zn in the growing medium. This review also remarks the critical role of the biotic and abiotic factors that may elevate or ameliorate the impact of ZnO NPs in terrestrial plants.
氧化锌纳米粒子（ZnO NPs）在化妆品、电子和光学工业中有广泛的应用。ZnO NPs 的广泛应用，特别是在个人护理产品中，表明它们可能会进入主要的环境基质，从而产生意想不到的影响。最近的文献表明，ZnO NPs 对陆地生物群具有有益或有害的影响，这方面的结果存在矛盾。在本综述中，我们全面调查了 ZnO NPs 暴露对各种陆地植物的有益和有害方面。仔细审查文献表明，在低浓度（约 50mg/kg）下，ZnO NPs 对植物有有益的影响。相反，在浓度高于 500mg/kg 时，它们可能会产生有害的影响，除非生长介质中缺锌。本综述还指出了生物和非生物因素的关键作用，这些因素可能会增加或减轻 ZnO NPs 对陆地植物的影响。
