One of the most important environmental pollutants is cement dust. In this study, RAPD technology was used to define the potential genotoxic impact of cement dust on plants. For this purpose, the DNA comparison of 12 plant species( Convolvulus sepium, Astragalus christianus, Taraxacum androssovii Medicago varia, Alyssum murale, Artemisia spisigera, Falcaria vulgaris, Anchusa strigose, Glaucium leiocarpum, Salvia syriaca, Cryciata taurica Tragopogon albinervis)collected from the areas of 10000 m (Control area) or 0-100 m away from Askale cement factory in Erzurum; was performed. 16 primers were used, and 390 bands were obtained. Important differences were observed in plant RAPD profiles collected from 0-100 m areas when compared to their respective controls (10000 m away from the factory). Some bands in control plants got lost, and new band formations were observed. The Genomic template stability (GTS) value decreased significantly in plants collected from 0-100 m area as compared to the controls (%56.20). Soil samples from 0100 m and control area were collected and examined for their heavy metal contents. According to the analysis results, Nickel, Cadmium, Zinc, Lead and Copper concentrations were found to be dramatically high in the soil collected from 0100 m as compared to the control area. These results indicate that the high heavy metal content in the soil causes the changes in RAPD profiles and GTS in plants. The data also indicated that RAPD and GTS assays are basic, effective and reproducible means of the genotoxicity control of environmental pollution.
