Sažetak
The toxicity of four waste water samples from reserve pit upon the root-tip cells of Allium ascalonicum L. was researched by applying modified Allium test. The samples were a mixture of substances and their chemical composition was only partly known. The first task was to find out the optimal duration for root-tips treatment. The treatment lasting 48 h has been accepted because it enables delivery of results only four days after the sample has been received. All undiluted four waste drilling fluid samples showed cytotoxicity as well as toxicity, which was proved by cytogenetic parameters such as high inhibition of mitotic activity or low mitotic index and high percentage of chromosomal and genomic aberrations. The toxicity was significantly reduced by increasing the degree of sample dilutions. The results of this investigation demonstrated that the modified Allium test could be easily used for detection of waste drilling fluids toxicity degree.
