Lead (Pb) toxicity has been a subject of interest for environmental scientists due to its toxic effect on plants, animals, and humans. An increase in several Pb related industrial activities and use of Pb containing products such as agrochemicals, oil and paint, mining, etc. can lead to Pb contamination in the environment and thereby, can enter the food chain. Being one of the most toxic heavy metals, Pb ingestion via the food chain has proven to be a potential health hazard for plants and humans. The current review aims to summarize the research updates on Pb toxicity and its effects on plants, soil, and human health. Relevant literature from the past 20 years encompassing comprehensive details on Pb toxicity has been considered with key issues such as i) Pb bioavailability in soil, ii) Pb biomagnification, and iii) Pb- remediation, which has been addressed in detail through physical, chemical, and biological lenses. In the review, among different Pb-remediation approaches, we have highlighted certain advanced approaches such as microbial assisted phytoremediation which could possibly minimize the Pb load from the resources in a sustainable manner and would be a viable option to ensure a safe food production system.
铅（Pb）毒性一直是环境科学家关注的课题，因为它对植物、动物和人类都有毒性作用。随着含铅相关工业活动的增加以及农用化学品、石油和油漆、采矿等含铅产品的使用，环境中的铅污染会随之增加，并可能进入食物链。作为最具毒性的重金属之一，通过食物链摄入铅已被证明对植物和人类是一种潜在的健康危害。本综述旨在总结铅毒性及其对植物、土壤和人类健康影响的研究进展。综述考虑了过去 20 年中与铅毒性相关的文献，其中包括土壤中铅的生物有效性、铅的生物放大以及铅的修复等关键问题，并从物理、化学和生物的角度进行了详细的阐述。在综述中，我们强调了一些先进的修复方法，例如微生物辅助植物修复，这可能以可持续的方式从资源中最小化铅的负载，并为确保安全的粮食生产系统提供可行的选择。
