Lichens as Biomonitors of Air Pollutants Deposition: Strategically Important Element Pollution

Ali ASLAN

Investigation of various species of lichen as biomonitors of air pollutants deposition and evaluation of element pollution were aimed. Maximum accumulation was 43.9±2.1 mg/kg in X. somloensis. Strontium in lichen species was quite high. Percentages of strontium for L.pulmonaria, C.furcata, U.longissima, X.somloensis, and F.caperata were between 58 and 78 indicating the efficient accumulation of strontium. Lichens were also accumulated strategically important elements. Maximum contamination factors in lichens were for strontium and tantalum. Maximum contamination factors of hafnium, niobium, li ...Более

Determination of some trace elements in various lichens as biomonitors of pollution and assessment of pollution status

Ali ASLAN

Some trace elements in various lichens as biomonitors of pollution were investigated. Also, the pollution status was assessed by enrichment factor, contamination factor, and pollution load index. Investigated elements were Ta, Bi, Hf, Nb, Ga, Sc, Li, Y, Ce, and Sr. The lichen species were Rhizoplaca chrysoleuca, Umbilicaria vellea, Aspicilia calcarea, Pseudevernia furfuracea, and Cetraria islandica. According to the results, lichen species accumulate Sr element well. The highest trace element accumulated by Pseudevernia furfuracea (21.7±1.0 mg/kg; 75), Rhizoplaca chrysoleuca (31.9±1.6 mg/kg; 6 ...Более

Screening of damage induced by lead (Pb) in rye (Secale cereale L.) – a genetic and physiological approach

İlhan DOĞAN

The fields in which lead (Pb) finds application in the modern world have increased dramatically in recent years. As a consequence of this intensive utilization of Pb, its toxicity tends to pose more and more environmental problems. The aim of this study was to evaluate the genotoxic potential of Pb and to characterize some physiological parameters in Secale cereale under Pb stress. Plants were subjected to different exposure levels of Pb (0, 100, 200 and 400 µmol/L) for two weeks. At the end of the experimental period, the effects of Pb exposure on the photosynthetic pigments content (chloroph ...Более

DETERMINING ELEMENT ACCUMULATIONS IN TURKISH RED PINE USED AS A BIOINDICATOR FOR ESTIMATING OF EXISTING POLLUTION ON BOTH SIDES OF BOSPHORUS IN ISTANBUL

İbrahim İlker ÖZYİĞİT

Evergreen Turkish red pine tree shows wide distribution around Aegean and Mediterranean regions in Turkey. Herein work investigated the mineral nutrient status of Turkish red pine as a bioindicator for revealing the impact of existing pollution on both sides of Bosphorus in Istanbul. For this, Al, B, Ca, Cu, Fe, K, Mg, Na and Zn concentrations were determined in unwashed and washed leaves and barks of the plant and soil samples. The standard procedures were applied and the determinations of element concentrations in all samples were done using ICP-OES. The sample collections were performed at ...Более
