Heavy metal (Cd, Cr, Cu, Ni, Pb, Zn) concentrations in spruce Picea abies L. along the roads of various traffic density in the Podhale region, Southern Poland
(2010) Korzeniowska, Joanna; Panek, Ewa
The aim of the paper was to determine influence of traffic density on heavy metal concentrations (Cd, Cr, Cu, Ni, Pb, Zn) in two years needles of spruce Picea abies L. along the roads of various traffic density located in the Podhale region, Southern Poland. The samples of Picea abies L. were collected along two roads: heavily frequented main road no. 95 Kraków - Zakopane between Chabówka and Nowy Targ and a district road of low traffic density no. 1644 Łopuszna - Dursztyn, between villages Łopuszna and Nowa Biała. The samples were collected along five transects: three at the road no. 95 and two at the road no. 1644 at the following distances from the road: 5 m, 10 m, 50 m and 100 m. Generally, metal concentrations descended according to the increasing distances from the road. The highest concentrations were stated in case of Cu, Ni and Pb at the distance 5 meters from the road Chabówka - Nowy Targ (10,1 ± 1,3 µg Cu/g, 2,9 ± 0,2 µg Ni/g and 2,4 ± 0,6 µg Pb/g), and the lowest concentrations with exception of Cd were stated for both mentioned roads at the distance 100 meters. Traffic density influenced heavy metal concentrations in spruce Picea abies L. The differences in metal concentrations along two roads were presented by concentration coefficients, calculated as quotient of metal concentrations at the roads of various traffic density. The highest concentration coefficients at the distance of 5 m were stated for: Ni (2.6), Pb (2.4) and Cu (1.7) and the lowest for Cd (0.5), Cr (0.9) and Zn (0.8).

The purpose of the studies was the elaboration of new, more sensitive methods of the biological monitoring of the pollution of surface waters with the application of ecotoxicological and embryological criteria for fresh-water invertebrates – Lymnaea stagnalis L. and Tubifex tubifex Müller in the relation to the monitoring with the applied method on Daphnia magna Strauss. Tested population were of 32 specimens (or more) of Tubifex tubifex and Lymnaea stagnalis (after hatching or during they embryological development in cocoons). Different chemical substances were tested in 24h and 48h LC 50% tests. The results were compared with the results for the Daphnia magna tests, as well as the degree of sensitivity for adult individuals and their embryonic forms were compared. The results undoubtedly show higher sensitivity of embryonic forms to chemical substances, compared to adult individuals.

The content of trace metals (Cd, Cr, Cu, Ni, Pb, Zn) in selected plant species (moss Pleurozium schreberi, dandelion Taraxacum officianale, spruce Picea abies) along the road Cracow – Zakopane
(2012) Korzeniowska, Joanna; Panek, Ewa
The goal of the paper was to define the phytoindication ability of selected plant species in the conditions of the impact of traffic on the environment. The contents of the following trace metals were analysed: Cd, Cr, Cu, Ni, Pb, Zn in three plant species: moss Pleurozium schreberi (Brid.) Mitt., dandelion Taraxacum officianale F. H. Wigg. And in Norway spruce Picea abies (L.) H. Karst alongside the communication route Kraków-Zakopane. The plant samples (green parts of moss, leaves of dandelion, and two year old needles of common spruce) were taken in seven transects perpendicular to the road in the following distances from the edge of the road: 5 m, 10 m, 50 m and 100 m. The moss Pleurozium schreberi turned out to be the best indicator among the tested plant species because it accumulated trace metals in the highest concentrations. In the leaves of the dandelion lower concentrations of metals were found, while the lowest ones were in the needles of the spruce.
