Sažetak
The toxicity of four oil industry waste water samples upon the root tip cells of Allium ascalonicum L. has been researched by applying modified Allium test. The samples were mixture of substances and their chemical composition was only partly known. The first task was to find out the optimal duration of root tips treatment. It has been established that the optimal exposure lasts 48, 72 or 96 hours. The treatment lasting 48 hours has been accepted because it enables delivery of results only four days after the sample had been received. Each of the samples observed was prepared in 3-5 different concentrations and the toxicity of each was investigated. Reduced toxicity by increasing the degree of dilution was observed by analysis of cytogenetic parameters such as mitotic index, chromosomal and genomic aberrations. Most aberrations found in the examined root tip cells were consequence of disturbance of mitotic spindle and chromosome stickiness.
