The metals involved in the oxidation-reduction reaction are vital to living beings, not being the case in non-redox metals. Relate the content of metals: copper, chromium, cadmium, zinc, iron, manganese, lead, mercury and arsenic between the plant species Aspidosperma rigidum (remocaspi) and the soil that sustains it, in the area of Nina Rumi and Puerto Almendra. The correlational research and experimental design, with three repetitions, had as a sample 2 kg of each fresh sample of root, bark and leaves, dried and weighed, then acid digested and analyzed in an atomic absorption spectrophotometer. The concentrations of the redox metals presented a concentration in the organs of the species, where Fe ˃ Zn ˃ Mn ˃ Cr ˃ Cu and the sample variation coefficient mostly show very low variability (0 ≤ CV ≤ 0.1) and low variability (0.1 ≤ 0.25), which indicates that the mean was representative of the sample; Average concentrations were on average ascending: soil from 0 to 20 <soil from 20 to 40 <root <bark <leaves. In the case of non-essential metals, Pb ˃ As ˃ Hg ˃ Cd and the sample variation coefficient mostly present very low variability (0 ≤ CV ≤ 0.1) and mercury that presented low variability (0.1 ˂ CV ≤ 0.25), being likewise the representative mean of the sample; the average concentrations were quite similar in the two pits, with a slight decrease in the root and then similar concentrations in the aerial organs, only the lead showed a descending behavior with higher concentrations in the soil samples that descended from the root to leaves. It was concluded that the trace elements analyzed were found in adequate concentrations in the organs of the plant, not the non-essential metals, where all were found above the VMP in plant material for medicinal use.
