Abstract

The paper investigates the use of cress (Zabava and Krupnolistovoi varieties) and wheat (Salavat Yulaev and Omskaya varieties) as phytoecological indicators. The object for testing was still waste liquid, the main waste of soda ash production. The toxicity was assessed by three parameters (seed germination, length and dry weight of the seedlings). It is shown that the still waste liquid has an acute toxic effect on all phytoecological indicators used. It has been found that the regression equations for seed germination and dry weight of seedlings in contrast to their average length for all plants do not adequately describe the experimental results and can not be used to evaluate the safe dilution factor. The safe dilution factor, determined by the average length of the seedlings, for cress Zabava is 34.7 and cress Krupnolistovoi is 34.4, and for wheat Salavat Yulaev is 73.0 and for wheat Omskaya is 81.8. It was established that the safe dilution factor determined with the use of different plant species varies quite strongly.
