Analiza statystyczna i geostatystyczna zanieczyszczeń wybranymi metalami śladowymi rzeki Odry

Obecność metali ciężkich w wodach powierzchniowych może mieć przyczyny naturalne i antropogeniczne. Na podstawie badań przeprowadzonych przez dr inż. Ewę Adamiec sprawdzono czy w zawiesinie rzecznej i wodach powierzchniowych doszło do akumulacji i transportu metali śladowych po powodzi tysiąclecia w 1997 roku na rzece Odrze. Celem pracy jest przeanalizowanie czy istniała zależność ilości metali śladowych w rzece i zawiesinie od odległości od pierwszego punktu pomiarowego w Chałupkach. Starano się znaleźć miejsca, w których ilość metali śladowych przekraczała wartości dopuszczalne oraz wyjaśnić ich przyczynę. Aby zwizualizować wyniki badań użyto programu komputerowego ArcGIS oraz arkusza kalkulacyjnego Excel.

Badanie zanieczyszczenia metalami śladowymi potoku Grzechynka i jego wpływ na rzekę Skawę
(Data obrony: 2013-09-27) Zajda, Joanna

Studies of the trace metals content were performed for bottom sediments of the Grzechynka stream to assess the local rivers anthropogenic pollution. Determination of Zn, Pb, Cd, Cr, Cu, Mn and Fe concentration in the size fraction < 63 ?m of sediments, allowed to identified the contamination level of trace metals in the Grzechynka stream sediments and their potential impact on the river Skawa. Low contamination was recorded for cadmium and copper, however, these values can not affect the river Skawa.

Metale w osadach dennych jeziora Wigry
(Wydawnictwa AGH, 2008) Prosowicz, Dorota
Concentrations of metals (Cd, Cr, Cu, Fe, Mg, Mn, Zn) were analyzed in main types of the bottom sediments of Wigry Lake. The concentrations of metals depend strongly on the lithological type of the sediment (carbonate gyttja, lacustrine chalk, detritous gyttja, clastic sediments). Results of the study were compared to geochemical backround and bottom sediments of different lakes. The highest concentrations of metals were found in detritous gyttja from Hańczańska Bay - the most polluted part of investigated area. Correlations between metals were presented. Most of presented metals in recent sediments of Wigry Lake occur bellow maximum allowable levels determined for unpolluted sediments. Concentrations of many elements in the recent sediments of Wigry Lake are much lower compared to those in many lakes in Poland and in the world.

Testing of selected phytoindicators for the environmental assessment of areas under various levels of pollution
(2012) Piotrowska, Karolina; Panek, Ewa
The aim of this paper was to determine the suitability of six plant species in biomonitoring of pollution from atmospheric trace metal deposition. Concentrations of Cu, Cd, Pb were determined in: mosses (Pleurozium schreberi, Polytrichum formosum), two years old needles of the Norway spruce (Picea abies), the common silver fir (Abies alba), the common larch (Larix decidua) and in leaves of the common white birch (Betula pendula). The material was collected in three different areas under various levels of pollution (Kraków Agglomeration, Spisz-Gubałów Foothills, Silesian Beskid). The highest concentrations of trace metals occurred in: the moss species Pleurozium schreberi: 6.17-10.83 mg Cu/kg d.w., 0.6-2.37 mg Cd/kg d.w., 7.0-27.17 mg Pb/kg d.w. and in the leaves of the common white birch: 4.82-15.33 mg Cu/kg d.w., 0.28-2.32 mg Cd/kg d.w., 1.33-5.41 mg Pb/kg d.w. In turn, the needles of the Norway spruce contain little amount of trace metals: 2.00-8.00 mg Cu/kg d.w., 0.07-0.45 mg Cd/kg d.w. and 0.17-3.83 mg Pb/kg d.w. The both moss species seem to be better biomonitors of atmospheric pollution in less polluted areas, because of higher elemental concentrations in most cases, espedally in terms of an ability to accumulate Pb and Cu. However, the common white birch is a better bioacumulator of Cd. This spedes has similar accumulation abilities as the common lardi. Both trees are good phytoindicators in the monitoring of highly contaminated areas. Spruce needles showed lower concentrations of trace metals than other species collected at the same site. However, all selected indicators are suitable for comparative studies on bioindication of urban and industrial air pollution.

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.
