Conclusion

In this chapter, we reviewed the sources of heavy metal contamination of sugarcane fields, focusing on the different heavy metals involved and their concentrations in different plant tissues. The high demand for cane sugar means that new areas are needed to grow sugarcane, and this demand for land can only be met by using marginal lands/landfills, thus accentuating heavy metal contamination problems. Findings to date clearly indicate the need for further research on the physiology of metal uptake and heavy metal tolerance in sugarcane plants, which will aid in the development of systems for remediating metal-contaminated soils.
