Multivariate statistics to investigate metal contamination in surface soil

Alagha, Omar
Tuncel, Süleyman Gürdal
The modification of soil composition in the urbanized area of Ankara due to wet-dry deposition and pollution-derived particles from the atmosphere is investigated by analyzing 120 surface soil samples, collected from the urbanized area and its un-urbanized surrounding, for major, minor and trace elements. Concentrations of elements from human activity (e.g. Cd, Pb, Cr, Zn, Cu and Ca) in the urbanized area were higher than their corresponding concentrations in global average soil and soil in un-urbanized areas outside the urbanized area. Metal contents in soil were very high in densely populated districts and around some industrial facilities. The only exception was Ph distribution, which was more dispersed, due to the nature of motor vehicle emissions. Alteration of the Cd, Zn, Cu and Cr content of soil was confined to the inhabited and industrial areas, whereas enrichment factors of these elements were close to unity in the remaining study area. Factor analysis identified two polluted soil factor associations. One factor includes elements, such as Zn and Cd, which had high factor scores in inhabited areas and the other factor (high loading of Pb) represents soil polluted by motor vehicle emissions.


Investigation of soil multi element composition in Antalya Turkey
Nilgün, güvenç; Omar, Alagha; Tuncel, Süleyman Gürdal (2003-08-01)
he chemical composition of 73 surface soil samples collected at the city of Antalya were analyzed for major, minor and trace elements to assess distribution of soil pollution, due to deposition of pollution-derived particles from the atmosphere. Comparison with data from rural area and distribution maps demonstrated that the composition of soil by metals is not significantly modified by anthropogenic activities in most of the city and its surroundings. In these areas, observed concentrations can be largely ...
Comparison of accumulation capacities of two lichen species analyzed by instrumental neutron activation analysis
Yenisoy-Karakas, S; Tuncel, Süleyman Gürdal (2004-01-01)
Instrumental neutron activation analysis and ICP-OES were used to determine 3 8 elements in two lichen species namely Xanthoria parietina (L.) Th. Fr. and Parmelia tiliacea (Hoffm) Ach. which were collected in Aegean Region of Turkey. It was found that the accumulation capacities of two species differed only for the elements Ca, Cl, Cu and Pb by using ANOVA at 95% confidence level. Average concentrations of all elements except for Ba, Mn and Hg were higher in Parmelia tiliacea. For the elements Ba, Br, Co, ...
Relative involvement of mantle and crustal components in the Agacoren granitoid (central Anatolia, Turkey): Estimates from trace element and Sr-isotope data
Güleç, Nilgün Türkan (1998-02-01)
Trace element contents, together with Sr-isotope ratios on a limited number of samples, are reported for the central part of the Agacoren granitoid in central Anatolia (Turkey), Trace element contents are depicted in terms of Ocean Ridge Granitoid (ORG)-normalized elemental patterns. The patterns display similarities to Volcanic Arc Granitoids (VAG) and/or Collision Granitoids (COLG), and are characterized by enrichment in Large Ion Lithophile (LIL) elements relative to High Field Strength (HFS) elements, n...
Obtaining soil-water characteristic curves by numerical modeling of drainage in particulate media /
Shoarian Sattari, Amir; Toker, Nabi Kartal; Department of Civil Engineering (2014)
The soil water characteristic curve (SWCC) reflects fundamental drainage properties of partially saturated soils by revealing the relation between soil suction and water content. Although during the past decades, various experimental methods have been proposed for obtaining the SWCC, these approaches are generally time consuming, expensive and highly dependent on operator skills. One solution to this has been sought through various empirical or physico-empirical formulations that link the SWCC to common soi...
Estimation of grain characteristics of soils by using cone penetration test (CPT) data
Ozan, Cem; Çetin, Kemal Önder; Department of Civil Engineering (2003)
Due to lack of soil sampling during a conventional cone penetration testing (CPT), it is necessary to classify soils based on recorded tip and sleeve friction and pore pressure (if available) values. However, currently available soil classification models are based on deterministic and judgemental determination of soil classification boundaries which do not address the uncertainties intristic to the problem. Moreover, size and quality of databases used in the development of these soil classification models ...
