Abstract

The problem of soil heavy metal pollution is becoming increasingly serious, and Pb is one of the main causes of soil heavy metal pollution due to its toxicity. Phytoremediation technology can reduce the content of heavy metal pollutants and improve soil nutrient conditions, and thus, it is more widely used. Pb in the soil affects the physiological and biochemical processes of plants, which in turn have a toxic effect on plants, causing severe wilting and death. Similarly, Pb also affects plant photosynthesis to varying degrees. This paper details the progress of research on the effects of soil Pb contamination on plants, with the aim of finding directions for further study.
