In this perspective article, we briefly describe what researchers working on oxidative stress induced by heavy metals have accomplished and what would likely be the next stage in the research on this subject. Many papers have been published focusing on the physiological aspects; many of them may look quite similar. We propose that the emerging new “omics” techniques that are being widely employed in other areas should also be adopted for the study of heavy metal-induced oxidative stress and the general effect on plant metabolism. We believe that it is also necessary to integrate different areas, such as biology, phytogeography, soil sciences and even anthropology to get a more dynamic view of the problem. Such changes might add significant new information to our knowledge on the subject.
