    Cluster analysis approach to identify metal sources in bottom sediments of Sultan Marsh canals, Turkey
    (2009) Yalcin M.G.
    The aim of this study was to determine heavy metal contents of the bottom sediments in Sultan Marsh water canals and drainage canals and possible sources of those heavy metals. The dendogram based on cluster analyses of the elements revealed two distinct groups of metals. There was a strong, positive correlation between some elements and their possible sources. Fe, Mn, Al, Ti, Cu, Zn and Cd concentrations in the canals were found to be high. It was attributed to the Fe mine in the south of the study area and the Fe smelting plants in the west of the study area. The heavy metals shown to reach high levels in the canals were thought to have toxic effects. The sediments of Sultan Marsh were affected by anthropogenic factors. That is, they were polluted by mines and industrial plants, and the ecological balance of Sultan Marsh is threatened. Copyright © 2009, Inderscience Publishers.

    Investigation of heavy metals pollution along the Nigde-Kayseri Road, Turkey
    (2007) Yalcin M.G.; Battaloglu R.
    The study area comprises the D765 state road connecting Nigde and Kayseri cities in the central Anatolia. The aim of this study is to determine the heavy metal contamination in off roadside soils along the D765 state road. Heavy metal concentrations were measured with Spectro-Xepos Benchtop X-Ray Fluorescence Spectrometer. Results of heavy metal analyses on soil samples reveal a significant contamination. Average heavy metal concentrations and standard deviations of samples collected from off roadside soils along the D765 state road are as follows: As: 27.90 (7.64), Cd: 3.99 (0.35), Co: 35.80 (2.19), Cr: 158.33 (46.27), Cu: 48.37 (24.73), Fe: 31516.83 (6545.26), Mn: 771.83 (121.41), Mo: 28.52 (5.51), Ni: 118.11 (27.90), Pb: 107.48 (37.90), Sn: 6.34 (1.35), Ti: 3369.87 (1172.44) Zn: 135.64 (32.42) mg/kg. In this study, among the heavy metals, As, Cd, Co, Cr, Mo, Ni and Pb are toxic metals. Heavy metal accumulations in soil were determined to be closely associated with traffic intensity.
