The Interactions among the Heavy Metals in Soils and in Weeds and Their Antioxidant Capacity under the Mining Activities in Thai Nguyen Province, Vietnam

<div>Principal component analysis of HM levels in 75 samples (3a), in 25 roots (3b), in 25 shoots (3c), and in 25 leaves (3d) from four species C. parasiticus, D. linearis, P. calomelanos, and P. vittata. Samples are colored and shaped according to different species. The length of the HM vector shows how high the concentration of these HMs levels is in the samples where this vector is directed toward. (a) All tissues, (b) roots, (c) shoots, and (d) leaves.</div>
