Some of heavy metals (Fe, Cu and Zn) are essential for plants and animals [6], their availability in medium varies, and metals such as Cu, Zn, Fe, Mn, Mo, Ni and Co are essential micronutrients [7], whose uptake in excess to the plant requirements result in toxic effects [8]. Short answer It has been shown that plants may already suffer from doubling the atmospheric CO 2 concentration from 340 to 610 ppm, something that might happen during the next hundred years or so based on current emissions..
