Geobotanical and biogeochemical characterization of mine overburden in Bor and its potential for application in remediation

Područje rudarskog basena Bor smatra se 'crnom ekološkom tačkom' i jednim od najzagañenijih područja u Srbiji. Rudarske aktivnosti prisutne na ovom području duže od jednog veka ostavile su teške posledice po životnu sredinu i rezultovale obrazovanjem tehnogenih tvorevina u vidu jalovišnog materijala značajne površine, koje predstavljaju snažan izvor zagañenja čitave oblasti prašinom, dok prirodno luženje koje sa njih vrše atmosferilije ugrožava okolno zemljište i vodotokove. Sanacija borskih jalovišta smatra se zato jednim od prioriteta u zaštiti životne sredine na nacionalnom nivou. Biološka remedijacija smatra se jednim od ekonomski i ekološki najprihvatljivijih remedijacionih tehnologija za sanaciju degradiranih područja. Fitoremedijacija je prirodna tehnologija koja koristi biljke da ukloni, dezintegriše ili zadrži štetne hemijske materije koje se nalaze u različitim medijumima životne sredine. Petrološka, mineraloška i geohemijska karakterizacija rudničkog otpada pružaju informacije o sastavu otkrivke i njenom hemijskom ponašanju, predstavljajući polaznu osnovu za utvrñivanje stepena ugroženosti životne sredine i prioriteta za sanaciju odreñene lokacije. Geobotanička i biogeohemijska karakterizacija ukazuju na stepen povezanosti procesa u podlozi, deposolu i biljnom svetu, dajući okvir za odgovarajući obim i vrstu fitoremedijacije kao biotehnološkog rešenja za sanaciju borskog rudničkog otpada. Samonikle biljne vrste na području rudničkih jalovišta prilagoñene su na ekološke uslove ovih staništa, što ih čini prvim izborom kod istraživanja za potrebe fitoremedijacije. Na odlagalištima otkrivke u Boru, formiranim neselektivnim odlaganjem rudničke otkrivke, petrološko-mineraloškom i geohemijskom karakterizacijom izdvojeno je šest zasebnih litoloških grupa, od kojih su sve izuzev intenzivno orudnjenih stena selektivno kolonizovane od strane samoniklih biljnih vrsta. Na njima su izdvojena četiri inicijalna vegetacijska stadijuma povezana sa utvrñenim litološkim grupama, odnosno karakteristikama deposola koji su nastali njihovim razlaganjem. Ova povezanost je naročito izražena meñu grupama podloga koje svojom mineralogijom generišu kiselu, i onih koje generišu neutralnu do blago baznu reakciju deposola..

Current conditions and future perspectives of grasslands in Serbia

Natural grasslands and pastures occupy 5.96% of the country territory. According to European Space Agency, changes in land cover from 2000–2015 indicate decrease in total grassland area of 1765 km2 (30.03%), emphasizing dominant conversion of grasslands to forests. Ongoing depopulation trend, rural to urban migrations, and decrease in livestock population are some of main factors impacting grasslands. This trend favors further naturalization of pastures striving to increase the areas under natural grasslands. Such conversion will contribute to overall change in biodiversity richness, especially in areas with saline soils and high mountain regions with increased level of endemic species. Grasslands play important role in overall sustainability, but their importance it is not properly addressed. Environmental experts should recognize drivers of grasslands degradation and propose appropriate conservation and restoration measures. The priority should be avoidance of grassland degradation that requires good assessment of their current conditions and monitoring of plant, soil, climate conditions and land use activities. Further measures are deduced to sustainable land management practices and smooth human interventions, whereas the aftermost adopted measures should be related to restoration. Grasslands should have more emphasized role in our society and LDN principles should be applied for their preservation

Orchid species Anacamptis morio as a potential bioremediator of As, Cd and Pb

In this study concentration of toxic elements as, Cd, and Pb were determined in different soil types and belonging orchid species Anacamptis morio vital parts, in order to examine accumulation patterns and provide new insights about the potential use of this orchid in bioremediation technology. Soils developed on limestone, serpentine, and the chert were subjected to the BCR sequential extraction. Samples of orchid roots and tubers, as underground parts, and stems, leaves, and inflorescences, as above-ground organs, were also analyzed for the content of as, Cd and Pb. During this research, it was observed that metal content in soil is directly proportional to its content in the plant, more specifically in roots, which suggests that A. morio can potentially be used in the phytostabilization of contaminated sites. Values for BCF factors showed Cd immobilization in roots regardless of the soil type. A certain level of arsenic was transferred from roots to leaves indicating the potential for accumulation of this element into aboveground organs. Assessment of the phytoremediation potential of this orchid or another plant species from diverse environments is important as it provides information about the possibility of their future application in environmental remediation programs

Impacts of Courtyard Envelope Design as an Important Architectural Parameter for Energy Savings

When designing facilities with lower energy consumption, the most crucial parameter is the correct choice of location. The terrain configuration has a distinct influence on the organization of the urban plan and the building design. It largely determines the microclimate, especially the temperature level, direction, and wind speed. The subject of this paper is the analysis of courtyard configuration as a dominant parameter in architectural design and energy savings. The courtyard is an open area that is tied to a specific building. It is usually surrounded by walls, other buildings, or a fence. The courtyard's dimensions significantly affect the project's development and the location's microclimatic characteristics. The courtyard's proportions and configuration directly affect the building's shape, so it is essential to consider the advantages and disadvantages of different influential parameters adequately. The influence of solar radiation on heat gains is evident, while it also increases the energy demand of buildings with different shapes and proportions of yards. Through an overview of various architectural aspects, the paper provides guidelines that can be useful to designers and spatial planners to form and select adequate courtyards for the buildings

A novel Tc 99m sorbent based on macroporous magnetic polymer

A novel magnetic macroporous poly(glycidyl-co-ethylene glycol dimethacrylate) (mPGME) synthesized by suspension copolymerization and functionalized with diethylene triamine (mPGME-deta) was evaluated as sorbent for pertechnetate ion (TcO4 - ) removal from aqueous solutions. Atomic force microscopy (AFM) was used for characterization. The kinetics of TcO4 - adsorption onto mPGME-deta is relatively fast and depends on pH.Physical chemistry 2016 : 13th international conference on fundamental and applied aspects of physical chemistry; Belgrade (Serbia); 26-30 September 201

Interaction of ammonium nitrate on the quality of soybean in autumn and spring on soil cultivation

Tokom 2020. i 2021. godine ispitivana je primena amonijum nitrata i NPK đubriva, kao i amonijum nitrata uz folijarnu primenu vodenog ekstrakta od ploda banane na prinos, sadržaj proteina i sadržaj ulja u zrnu soje. Sve kombinacije đubriva statistički veoma značajno povećavaju prinos soje i sadržaj proteina u zrnu, dok je sadržaj ulja statistički veoma značajno smanjen.During 2020 and 2021 ammonium nitrate was tested, ammonium nitrate and NPK fertilizers, as well as ammonium nitrate with foliar application of water extract from banana fruit was investigated on yield, protein content and oil content in soybeans. all combinations of fertilizers statistically significantly increase soybean yield and grain protein content, while oil content in statistically significantly reduced
