Bu çalışmada Isparta İli Şehir Merkezi Girişi ile Süleyman Demirel Üniversitesi arasındaki 10 km’lik yol boyunca sıralanan, Cupressus sempervirens ve Cedrus libani ağaçlarının yapraklarında taşıtların sebep olduğu kurşun (Pb) kirliliği araştırılmıştır. Sonuçta her iki bitki türünde de kurşun (Pb) kirliliğinin şehre yaklaştıkça arttığı belirlenmiştir. Ayrıca Cupressus sempervirens bitkisinin yaprağının anatomik yapısından dolayı Cedrus libani’ye göre daha fazla kurşun (Pb) içerdiği de tespit edilmiştir

In this study, lead (Pb) pollution in leaves of Cupressus sempervirens and Cedrus libani trees that grow alongside a ten km motor road between University of Süleyman Demirel and Centrum entrance of Isparta City was investigated. As a result, lead (Pb) pollution in leaves of both of plant species was increased more and more as getting closer the City. Morover, because of anatomical structure of Cupressus sempervirens leaves, this plant was determined to contain much more heavy metal than Cedrus libani do
