The present study investigated the trace element contents in the blood sera of type II diabetic patients with and without complication as compared to non-diabetic healthy controls. The elements Na, Mg, Al, Si, P, S, Cl, K, Ca, Cr, Mn, Fe, Ni, Cu, Zn, Se, Mo, Cd, Hg and Pb were determined by wavelength dispersive x-ray fluorescence spectrometry. Blood serum levels of some trace elements in patients with type II diabetes mellitus showed significant deviations from healthy controls. Mean Ca, Cu and Se (p < 0.05) concentrations (%) in both diabetic patients with and without complication were significantly lower than those in healthy controls. When compared with non-diabetic control group, the Mg concentrations of patients without complication were decreasing while Mg levels of patients with at least one complication were increasing (p < 0.05). Si levels were significantly higher both in diabetic patients with complication and without complication than healthy controls (p < 0.05). K and Hg levels of diabetic patients with at least one complication have significantly deviated from both healthy controls and patients without complication (p < 0.05). There were no significant differences between control group and diabetic patients concerning height, age, weight and body mass index (p > 0.05).

In the present study, it was aimed to determine the effects of cement dust pollution on contents of some significant essential elements (P, S, K, Ca, Fe and Cl) in wild plants (Medigago varia, Anchusa leptophylla, Euphorbia orientalis, Lactuca serriola, Artemisia spicigera, Crambe orientalis, Convolvulus sepium and Senecio vernalis) using wavelength-dispersive spectrometer X-ray fluorescence technique. Plant samples were collected from different locations around a cement factory which is located at Askale about 50 km from Erzurum (Turkey). The element contents in the plant specimens that existed in both 0-100 m (dense dusted) and 2000 m (undusted) areas were compared. P, S, K and Cl contents were found to be high in the plants growing in areas 0-100 m from the cement factory, compared to same plants at 2000 m far from the factory. However, Ca and Fe contents were determined to be low in plants growing in 0-100 m area from the factory. Results of the study can contribute to understand how mineral deficiency and toxicity lead to detrimental effects on plant growth and development in the fields contaminated by cement dust.
