  Assessment of heavy metal accumulations (Cd, Cr, Cu, Ni, Pb, and Zn) in vegetables and soils

  Osma, Etem; Serin, Memduh; Leblebici, Zeliha; Aksoy, Ahmet

  This study measured levels of cadmium, chromium, copper, nickel, lead, and zinc in fruits of Capsicum annuum L., Phaseolus vulgaris L., and Solanum melongena L. during the 2007 vegetation period, to determine levels of metal pollution in Istanbul Province. Plant and soil samples were collected from six sites in Istanbul (Brook Coast area, inner city, industrial area, suburban, roadside, and rural - control - areas). Unwashed and washed leaf and soil samples were analyzed using inductively coupled plasma optical emission spectrometry. The highest and lowest values were as follows: Cd (0.28-0.89 μg·g-1), Cr (5.33-14.04 μg·g-1), Cu (1.47-5.19 μg·g-1), Ni (3.06-13.65 μg·g-1), Pb (29.28-86.20 μg·g-1), and Zn (3.70-5.74 μg·g-1). The unwashed samples were more contaminated than the washed samples. Contamination was higher in the vegetables grown in industrial areas and along roadsides. The overall metal concentration pattern in vegetables was Pb > Cr > Ni > Zn > Cu > Cd.

  Heavy metals accumulation in some vegetables and soils in İstanbul

  Osma, Etem; Serin, Memduh; Leblebici, Zeliha; Aksoy, Ahmet

  Bu çalışmada, 2007 yılında, dere kıyısı, şehir içi, sanayi bölgesi, kenar semt, yol kenarı ve kontrol bölgesi olmak üzere İstanbul’un toplam altı lokasyonundan, Petroselinum crispum, Brassica oleracea var. acephala, Beta vulgaris var. cicla’ya ait yıkanmış ve yıkanmamış sebze örnekleri ile yetiştikleri toprak örnekleri toplanarak altı toksik metalin miktarı tespit edilmiştir. Toplanılan örneklerde Cd, Cr, Cu, Ni, Pb ve Zn miktarları, ICPOES kullanılarak tayin edilmiştir. Yıkanmamış örneklerde metal birikiminin en fazla olduğu bulunmuştur. Endüstriyel ve yol kenarlarında yetişen bitkilerde ise metal birikiminin daha fazla olduğuna ilişkin bağlantı tespit edilmiştir. Elde edilen sonuçlara göre bitkilerde ağır metallerin en yüksek ve en düşük değerleri Cd için 0,28-0,89 μg/g kuru ağırlık, Cr için 5,33-14,04 μg/g kuru ağırlık, Cu için 1,47-5,19 μg/g kuru ağırlık, Ni için 3,06-13,65 μg/g kuru ağırlık, Pb için 29,28-86,20 μg/g kuru ağırlık ve Zn için 3,70-5,74 μg/g kuru ağırlık arasında değişim göstermektedir. Bitkilerde toplam metal konsantrasyonlarının sıralanışı Pb>Cr>Ni >Zn>Cu>Cd şeklindedir.

  Heavy metals accumulation in some vegetables and soils in Istanbul; [İstanbul'da bazı sebzeler ve topraklarda aǧır metal birikimi]

  Osma, Etem; Serin, Memduh; Leblebici, Zeliha; Aksoy, Ahmet

  This work was designed to assess the concentration of six toxic metals in the soil and in unwashed and washed samples of different vegetable species (Petroselinum crispum, Brassica oleraceae var. acephala, Beta vulgaris var. cicla collected from six different sites (stream side, inner city, industrial, suburban, roadside, and rural) in Istanbul in 2007. Concentrations of Cd, Cr, Cu, Ni, Pb, and Zn were determined by using ICP-OES. It was found that the average highest values of metal accumulations were detected in unwashed samples. The correlation was significant between metal accumulations and the sites, where the vegetables were grown, in the industrial areas and along the roadsides. The highest and lowest average values in the vegetables varied between 0.24-0.89 μg/g dw for Cd, 3.73-14.04 μg/g dw for Cr, 1.47-5.19 μg/g dw for Cu, 3.13-13.65 μg/g dw for Ni, 29.28-87.00 μg/g dw for Pb, and 3.48-5.74 μg/g dw for Zn. The pattern of total metal contrations in the vegetables followed Pb>Cr>Ni>Zn>Cu>Cd.

  Determination of heavy metal concentrations in tomato (Lycopersicon esculentum Miller) grown in different station types

  Osma, Etem; Ozyigit, Ibrahim Ilker; Leblebici, Zeliha; Demir, Goksel; Serin, Memduh

  In this study, washed and unwashed tomato fruits (Lycopersicon esculentum Miller) were collected from six different station types such as; brook coast, suburban area, industrial area, inner city, roadside and village (control) in Istanbul-Turkey, in 2009. Unwashed and washed fruit samples were used to analyze cadmium, chromium, copper, iron, nickel, lead and zinc concentrations by using inductively coupled plasma optical emission spectrometry. It was observed that washing procedure reduced concentrations of all heavy metals related to station types. In accordance with the results, the lowest and highest heavy metal accumulations measured in fruits were as follows; cadmium (0.17-0.40 μg/g dw), chrome (0.94-5.67 μg/g dw), copper (7.67-14.27 μg/g dw), iron (19.16-64.53 μg/g dw), nickel (1.02-11.64 μg/g dw), lead (4.31-5.51 μg/g dw) and zinc (1.36-3.07 μg/g dw). As a result, the relative abundance of heavy metals in tomato samples were observed as iron>copper>nickel>chrome>lead>zinc>cadmium. According to the results of this study, it can be said that tomato fruits reflect heavy metal amounts well in polluted areas such as urban, industrial and roadside when compared to unpolluted (control) areas with their washed and unwashed samples.
