Sumario:Title screen
In this work, problems arising by use of active biomonitoring are discussed. Biomonitoring technique using positioned vertically frameworks and epiphytic moss Pylaisia polyantha is proposed. The influence of tree species on which the bark of the frameworks is fixed, altitude, and orientation is researched. For this purpose, frameworks were placed at two sampling sites of Tomsk on different trees (poplar, birch), at altitudes of 0.5 and 1.5 and with different orientations in May; the exposure time was 20 weeks. The concentrations of As, Ba, Br, Ca, Ce, Co, Cr, Cs, Eu, Fe, Hf, K, La, Lu, Mo, Rb, Sb, Sc, Sm, Tb, Th, U, Yb, and Zn were determined by neutron activation analysis at the research reactor of Tomsk Polytechnic University. Increasing concentrations of half of the chemical elements was revealed during the exposure. The high-capacity frameworks used to accumulate certain elements—Cs, Eu, Hf, K, Lu, Sb, Yb—were revealed.
