A Study of Hazards of Soil Heavy Metals Cu Stress on Plants

In recent years, heavy metals pollution in soil is more and more serious, which has been attracting more and more attentions. The excess usage of copper bactericide and industrial pollution had caused severe copper toxicity to plants. This article made a brief review on the research progress, including heavy metals Cu toxicity, mechanism of plant resistance to Cu stress and phytoremedia- tion, and we outlook the trends on how to investigate soil heavy metal pollution of Cu in the future.
