镉是环境中的一种重要污染物，对大多数生物体有毒，对人类健康构成潜在威胁：农作物和其他植物从土壤或水中吸收镉，并可能在其根和芽中富集。在这篇综述中，我们总结了镉毒性发生的自然和人为原因，并评估了在添加镉的土壤或营养液中生长的植物观察到的植物毒性效应。镉诱导的效应包括氧化应激、遗传毒性、光合机构的抑制和根代谢的抑制。我们解释了这些毒性模式之间提议的和可能的相互作用。在讨论最近和较早的研究时，我们进一步强调实验的环境相关性和植物的生理反应。
Cadmium is an important pollutant in the environment, toxic to most organisms and a potential threat to human health: Crops and other plants take up Cd from the soil or water and may enrich it in their roots and shoots. In this review, we summarize natural and anthropogenic reasons for the occurrence of Cd toxicity, and evaluate the observed phytotoxic effects of plants growing in Cd-supplemented soil or nutrient solution. Cd-induced effects include oxidative stress, genotoxicity, inhibition of the photosynthetic apparatus, and inhibition of root metabolism. We explain proposed and possible interactions between these modes of toxicity. While discussing recent and older studies, we further emphasize the environmental relevance of the experiments and the physiological response of the plant.
