Bu çalışma ile Türkiye’de şehir peyzaj planlamasında çok sık rastlanılan Robinia pseudoacacia L. “Umbraculifera” taksonu kullanılarak Şanlıurfa il merkezinde motorlu taşıtların neden olduğu ağır metal kirliliği seviyesinin belirlenmesi amaçlanmıştır. Mevsimsel olarak toplanan yaprak örneklerinde ICP (Inductively Coupled Plasma) kullanılarak Pb, Zn, Cu, Ni ve
Cd ağır metal miktarlarının tespiti yapılmıştır. Bu bitkinin yapraklarından ağır metal birikiminin istasyonlara ve mevsimlere göre anlamlı derecede birbirinden farklılığını tespit etmek için SPSS 18 Paket Programı ve farklılığını ölçmek için ise homojenlik testi uygulanmış, Kruskal – Wallis ve Games – Howell testleri ile veriler analiz edilmiştir. Çalışma sonucunda elde edilen verilere göre bu bitkinin Şanlıurfa’da motorlu taşıt kaynaklı ağır metaller için bir indikatör olamayacağı sonucuna varılmıştır. 

An Investigation on Heavy Metal Pb, Zn, Cu, Ni and Cd Accumulation in Leaves of Robinia Pseudoacacia L. “Umbraculifera” Arising from Motor Vehicles

Öz

The present study aims to determine the level of heavy metal contamination induced by the motor vehicles at Şanlıurfa city center using Robinia pseudoacacia L. "Umbraculifera" taxon encountered frequently at the urban landscape planning practices in Turkey. The quantities of the heavy metal levels such as Pb, Zn, Cu, Ni and Cd were determined using ICP OES (Inductively Coupled Plasma Optical Emission Spectrometer) on the leaf samples collected seasonally (spring, summer, autumn seasons). The SPSS 18 Packaged Software was used to determine the significant differences regarding accumulation of the heavy metal levels from the leaves of this plant according to the stations and the seasons, and the homogeneity test was implemented to measure the difference; and the data were analyzed using Kruskal - Wallis and Games - Howell tests. Based on the data acquired as a result of the study, it was concluded that this plant cannot be considered as an indicator for heavy metals originating from motor vehicles in Şanlıurfa.
