In this study, both seasonal and spatial variations in trace metal uptake, as well as concentration of photosynthetic pigments in Silver birch (Betula pendula Roth.) trees in five urban parks in Pančevo, Smederevo, Obrenovac and Belgrade (Serbia) affected by different anthropogenic activities were studied. The characteristics of soil were assessed in terms of texture, pH and trace element content. Concentrations of boron, strontium and zinc in both leaves and bark showed an increasing temporal trend, however, copper showed an opposite seasonal trend. A higher accumulation of trace elements was noticed in leaves compared to bark. The obtained results for photosynthetic pigments showed low sensitivity of birch to B, Cu, Sr and Zn contamination, indicating that birch tolerates pollution and climate stress by increasing the amount of pigments. Analysis of the effects on soil chemistry of trace element accumulation in plant tissues proved that soil chemistry poorly explains the variability

Evaluation of urban contamination with trace elements in city parks in Serbia using pine (Pinus nigra Arnold) needles, bark and urban topsoil Pavlović, Marija; Pavlović, Dragana; Kostić, Olga; Jarić, Snežana; Čakmak, Dragan; Pavlović, Pavle; Mitrović, Miroslava (International Journal of Environmental Research, 2017)Urban environments are strongly influenced by anthropogenic activities, which are often reflected by a high degree of contamination in relation to the natural environment. Concentrations of five trace elements (B, Cr, Cu, ...
Seasonal variations of trace element contents in leaves and bark of horse chestnut (Aesculus hippocastanum L.) in urban and industrial regions in Serbia Pavlović, Marija; Rakić, Tamara; Pavlović, Dragana; Kostić, Olga; Jarić, Snežana; Mataruga, Zorana; Pavlović, Pavle; Mitrović, Miroslava (Archives of Biological Sciences, 2017)In this study, we examined the ability of horse chestnut (Aesculus hippocastanum L.) to capture heavy metals, and whether its capacity to absorb metals from soil is associated with surrounding ecological characteristics ...
Pavlovic, Miomir G.; Pavlovic, Miroslav M.; Pavlovic, Marija M.; Nikolic, Nebojsa D. (International Journal of Electrochemical Science, 2014)It is known that silver, even in small concentrations (hundred parts of milligrams per liter), has the ability to destroy microorganisms, i.e. it has strong bactericidal abilities. Cleansing vast amount of water ...
