Cytogenetic effects of C6H4 (CH3)2 (xylene) on meristematic cells of root tips of Vicia faba L. and mathematical analysis
Keywords:Abnormalities; Chromosome; Mathematical analysis; Xylene
Xylene is a readily flammable and poisonous liquid with a chemical formula of C6H4 (CH3)2. It is used as raw material or auxiliary raw material in many industrial products such as dye, pencil, agricultural chemicals, rubber, fiber, glue and diaper. In this study, cytogenetic effects of xylene, on the meristematic cells of root tips of Vicia faba L. used as food have been investigated. For this purpose, the seeds of the plant have been treated with xylene solutions prepared in different concentrations for different time periods. Chromosomes at the root tips have been looked and the effect of xylene has been determined. The abnormalities as chromosome breaking, chromosome dispersion, bridge chromosome, chromosome adherence, ring chromosome have been observed. Abnormalities have been seen at each treatment depended on the time periods. The environment where xylene, a carcinogenic substance, is present at 100 ppm or more than 435 mg/m3 in air is harmful to human health. In addition to these visible damages of xylene in the study, possible damages on chromosomes carrying genetic codes of living beings to future generations have been investigated and mathematical analyzes has been made. The results obtained have been evaluated statistically.
