<abstract xmlns="http://www.w3.org/1999/xhtml"><p> During the research, cumulative properties of conifer needles P. armandii, P. banksiana, P. mugo, P. nigra, P. sylvestris and P. wallichiana in reference to Cu, Ni, Mn, Fe, Zn and Cd were analysed, and the factors which have an impact on the chemical composition of the bark of those species were identified. During the study, the age of needles and the content of the examined components in soil was taken into consideration. The content of metals in the needles varied, depending on a species and the age of the coniferous needles. In most cases, a higher level of content of those metals was determined in 2 years old needles, except for Cu and Zn (P. banksiana) as well as Zn (P. nigra), in which case, higher concentration of metals in 1 year old needles was determined. The obtained results indicate that the heavy metals’ concentration in the samples of needles was relatively low, except for Ni (P. armandii, P. sylvestris, P. wallchiana) and Cd (P. armandii, P. banksiana), which showed higher levels. Among the examined elements, Mn was accumulated in the largest volume in the needles of P. banksiana, Fe and Cu in the needles of P. wallchiana, Ni in the needles of P. sylvestris, Zn in the needles of P. nigra and Cd in the needles of P. armandii. The bark samples represented a clearly acidic reaction, with pH levels from 3.7 (P. sylvestris) to 4.9 (P. armandii). The highest quantities of Mn, Fe, Cu and Cd were accumulated by the bark of P. armandii, Ni in the bark of P. sylvestris and Cu in the bark of P. mugo.</p></abstract>
