    Using the Turkish Red Pine Tree To Monitor Heavy Metal Pollution
    (HARD, 2020) Yalçın, Ertuğrul; Özyiğit, İbrahim İlker; Doğan, İlhan; Demir, Göksel; Yarcı, Celal
    Turkish red pine is an evergreen tree species widely distributed in the Aegean and Mediterranean regions in Turkey. In the present work, the heavy metal pollution level in Istanbul was investigated using Turkish red pine as a biomonitor. For determining heavy metal concentrations (Cd, Co, Cr, Mn, Ni and Pb) in leaf (unwashed and washed) and bark samples of Turkish red pine and its co-located soil samples we used ICP-OES. Additionally, particulate matter profiles of the research areas were investigated. The samples were collected from 5 different localities: 4 from the Bosporus region (Yildiz Grove, Fethi Pasha Grove, Baltalimani Grove and Mihrabad Grove) and one from Prince Island, also known as Buyukada (as control). According to our measurements, the highest heavy metal accumulations (in mg kg(-1) DW) in plant part samples were measured between 1.526 +/- 0.012 and 1.639 +/- 0.015 for Cd, 0.543 +/- 0.007 and 0.600 +/- 0.009 for Co, 5.110 +/- 0.064 and 5.648 +/- 0.072 for Cr, 9.347 +/- 0.105 and 10.331 +/- 0.111 for Mn, 7.483 +/- 0.091 and 8.271 +/- 0.096 for Ni, and 13.848 +/- 0.159 and 14.950 +/- 0.167 for Pb, while the highest heavy metal accumulations (in mg kg(-1) DW) in soil samples were measured between 1.813 +/- 0.021 and 1.974 +/- 0.029 for Cd, 6.326 +/- 0.082 and 6.992 +/- 0.091 for Co, 22.017 +/- 0.284 and 23.685 +/- 0.301 for Cr, 268.333 +/- 3.153 and 297.361 +/- 3.529 for Mn, 15.194 +/- 0.176 and 16.792 +/- 0.193 for Ni, and 68.778 +/- 0.715 and 74.514 +/- 0.883 for Pb. The highest outdoor particulate matter levels (in mu g/m(3)) in research areas were also determined as 27.103 for fine (PM2.5) and 67.792 for coarse (PM10) aerosols. The findings revealed that Turkish red pine could accumulate noteworthy amounts of heavy metals.

    Determining Element Accumulations in Turkish Red Pine Used as a Bioindicator for Estimating of Existing Pollution on Both Sides of Bosphorus in İstanbul
    (Parlar Scientific Publications, 2020) Yalçın, İbrahim Ertuğrul; Özyiğit, İbrahim İlker; Doğan, İlhan; Demir, Göksel; Yarcı, Celal
    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 five different locations in Istanbul, 4 from the Bosphorus region and one from Prince Island (as control). The highest element concentrations (in mg kg(-1) DW) in plant parts were recorded between 109.10 +/- 1.68 and 120.58 +/- 1.75 for Al, 10.18 +/- 0.14 and 12.52 +/- 0.17 for B, 8765.42 +/- 92.41 and 9600.69 +/- 102.22 for Ca, 10.91 +/- 0.13 and 11.73 +/- 0.16 for Cu, 226.85 +/- 3.01 and 254.07 +/- 3.20 for Fe, 4050.69 +/- 48.51 and 4477.08 +/- 52.34 for K, 794.58 +/- 9.82 and 878.33 +/- 10.07 for Mg, 1255.14 +/- 14.67 and 1374.31 +/- 18.55 for Na and 34.92 +/- 0.49 and 37.25 +/- 0.57 for Zn while the highest element concentrations (in mg kg(-1) DW) in co-located soil samples were measured between 5470.42 +/- 66.48 and 6046.25 +/- 73.54 for Al, 14.86 +/- 0.20 and 16.43 +/- 0.29 for B, 4600.56 +/- 55.22 and 4984.86 +/- 62.71 for Ca, 22.33 +/- 0.36 and 25.07 +/- 0.48 for Cu, 5500.01 +/- 71.05 and 5953.06 +/- 80.16 for Fe, 1819.44 +/- 23.51 and 2029.17 +/- 27.04 for K, 4108.75 +/- 50.77 and 4714.17 +/- 58.09 for Mg, 111.11 +/- 1.82 and 122.08 +/- 2.45 for Na and 117.10 +/- 2.33 and 126.86 +/- 2.61 for Zn.
