152and 4). Higher contamination by heavy metals (Fe,Cu, Co, As and Sb) in other plant parts is mostlya weak increase of their concentrations comparedwith concentrations in leaves, e.g. Cu concentrations8 vs.7. As concentrations 0.16 vs. 0.13. Coconcentrations 2 vs. 1.3 ppm in plant from the referencesite.The comparison of additive concentrations ofheavy metals in individual types of plant tissues(roots, branches/stems and leaves/needles) wascarried out to obtain more complex contaminationmodel of the plant tissues. The comparison wasperformed with the following wood species andherbs: Betula pendula, Quercus petraea, Piceaabies, Abies alba, Pinus sylvestris, Juncus articulatus,Mentha longifolia. It was possible to collecttheir samples from the dump-field and referencesite, respectively. The study showed (Fig. 2) thatthe highest concentrations of Fe, Pb, As, Sb and Znwere determined in the root system. Cu contaminatesleaves and needles in preference. Fe probablyenters leaves and needles up to certain concentrationlevel in preference. When this concentrationlevel is exceeded, Fe accumulates in root systemafter it cannot enter leaves and needles.The contamination of plant tissues of live anddead branchess was compared in several plantsfrom the dump-field (Betula pendula, Pinus sylvestris,Picea abies) and reference site (Betula pendula,Quercus petraea) (tabs 3 and 4). Betula pendulafrom the dump-field (tab. 3) showed higher As andSb concentrations in live branches. Higher concentrationsof Fe, Cu, Zn, Pb, Ag, Cd, Ni and Cowere determined in dead branches. Pinus sylvestris(tab. 3) showed higher concentrations of Fe,Cu, Pb, Ag, (Cd), Ni, Co and Sb in live branchesTab. 4 Analyses of plant tissues from the reference site Ľubietová – PodlipaPlantBetulapendulaQuercuspetraeaPinussylvestrisPiceaabiesAbiesalbaJuncusarticulatusMenthalongifoliaSiteSampleBLB-10BLB-9ALB-101ALB-202BLB-113BLB-114BLB-101Partof theFe Cu Zn Pb Ag Cd Ni Co As Sbplantppma 192.0 2.0 27.10 19.20 0.02 0.06 5.10 2.30 0.31 0.20b 107.7 3.5 16.90 14.80 1.30 0.02 3.00 7.70 0.12 0.27b 2108.8 5.6 41.30 75.60 1.90 0.12 1.70 6.70 0.20 0.05c 209.0 6.9 25.50 3.10 5.40 0.07 4.70 1.80 0.14 0.04a 174.2 4.2 32.00 31.10 0.08 0.06 7.82 1.53 0.35 0.19b 67.1 0.0 25.40 2.00 0.02 0.04 3.40 1.80 0.06 0.04b 2158.6 3.2 36.30 30.40 0.20 0.06 3.80 1.00 0.63 0.07c 123.2 3.1 27.50 22.20 0.05 0.03 2.80 1.30 0.16 0.09a 111.1 8.1 10.20 10.80 0.05 0.02 2.00 2.00 0.16 0.51b 84.0 0.0 12.80 11.40 1.20 0.02 2.20 0.30 0.04 0.03c 136.8 6.6 22.90 17.00 0.10 0.06 4.50 1.30 0.13 0.06a 121.6 4.5 22.40 28.60 0.04 0.05 4.11 4.10 0.33 0.52b 95.2 8.1 10.20 1.15 0.55 0.60 7.10 5.10 0.07 0.06c 90.8 7.4 10.01 1.11 0.48 0.52 7.00 4.20 0.17 0.08d 84.1 2.1 8.63 0.98 0.60 0.02 8.20 0.70 0.57 0.16a 98.1 3.4 19.70 10.00 0.80 0.04 5.13 1.11 0.39 1.20b 112.8 4.6 20.00 11.80 0.80 0.04 4.30 1.40 0.07 0.03c 41.7 3.0 17.20 22.40 3.50 0.03 4.90 0.70 0.15 0.11a 199.5 34.1 39.50 4.30 0.20 0.08 5.10 1.00 0.59 0.18b 103.2 8.8 42.90 15.40 0.50 0.05 3.00 1.30 0.16 0.07c 100.4 8.0 38.12 15.41 0.49 0.03 2.99 1.30 0.17 0.05d – – – – – – – – 0.31 0.06a 246.0 100.4 23.30 16.00 0.20 0.06 4.70 1.20 0.57 0.21b 89.4 14.3 12.10 11.40 0.04 0.04 2.40 0.50 0.05 0.08c 593.6 173.3 38.30 41.20 2.40 0.10 7.60 3.30 0.76 0.26d – – – – – – – – 1.44 2.07
