Terzili – Yerköy - Yozgat Cu yataðý ve çevresinde yetiþen Euphorbia cyparissias bitkisinin biyojeokimyasal olarak incelenmesi, Türkiye

Çalýþma alaný, Terzili köyü (Yerköy - Yozgat) Kýrþehir’de yer almaktadýr. Bu bölgede yetiþen Euphorbia cyparissias (sütleðen) bitkisi ve üzerinde yetiþtiði toprak örneklerinden toplam 20 adet örnek toplanarak analizi yapýlmýþtýr. Ýnceleme alanýndan toplanan bu bitkinin dalýnda As, Co, Fe, Ni, Ag ve V element deðerleri, yapraklarýnda As, Cr, Co, Fe, Ni, Ag, Th ve V element deðerleri ve bu bitkinin üzerinde yetiþtiði toprak örneklerinde (Fe ve Th dýþýnda) tüm element deðerleri, bitki ve toprak için önerilen deðerlerden yüksektir. Toprak örneklerindeki Pb ve Th deðerleri ile pH deðerleri herbir örnek lokasyonunda paralel daðýlým gösterirken, Ag, Co, Cu, Ni, U, V ve Zn deðerleri, herbir lokasyonda pH azalýrken artmakta veya pH artarken azalmaktadýr. Düþük pH þartlarýnda bu elementlerin çözünürlüðünün yüksek olduðu görülmüþtür. Toprak örneklerinde element çiftleri arasýnda; Al-Cr, Co-Ni, Cu-Fe ve Al-Mn pozitif yüksek korelasyon görülmektedir (p<0.01, p<0.05).
Ag(toprak/yaprak) (n = 10, r = 0.65, p<0.05), Mn(toprak/yaprak) (n = 10, r = 0.68, p<0.05), As(toprak/dal) (n = 10, r = 0.92, p<0.01) ve Pb(toprak/dal) (n = 10, r = 0.53, p<0.05) açýsýndan E. Cyparissias bitkisinin dalý ve yapraðý belirtgen (indikatör) bitkilerin aranmasýnda kullanýlabilirler.

Biogeochemical examination of Euphorbia cyparissias plant in Terzili – Yerköy – Yozgat Cu deposits and its around, Turkey

The study area is located in the Kýrþehir Ý32-b3 section in Terzili village (Yerköy - Yozgat). A total of 20 samples were analysed after collected from Euphorbia cyparissias (sütleðen) plant which grows in this region and from the soil where this plant grows. Since As, Co, Fe, Ni, Ag and V element values on the stems of this plant collected from the study area, As, Cr, Co, Fe, Ni, Ag, Th and V element values on the leaves of this plant, and all the element values (except for Fe and Th) in the soil where this plant grows are higher then the suggested values. While the Pb and Th values and pH values in the soil samples are parallel to each sample location, the values of Ag, Co, Cu, Ni, U, V and Zn are increased when the pH is decreased or decreasing while the pH is increasing at each locus. At low pH conditions, the solubility of these elements is high. At the soil samples, higher positive correlation is seen between pairs element Al-Cr, Co-Ni, Cu-Fe and Al-Mn (p<0.01, p<0.05). The stem and leaf of the E. Cyparissias plants could be used in the search for indicator plants in terms of Ag (soil/leaf) (n = 10, r = 0.65, p<0.05), Mn (soil /leaf) (n = 10, r = 0.68, p<0.05), S As (soil /stem) (n = 10, r = 0.92, p<0.01) and Pb(soil /stem) (n = 10, r = 0.53, p<0.05).
