Toxicity of industrial waters at several stages of treatment in model experiment was esteemed in Allium test. It was shown that ability of water to inhibit growth of onions roots decreased together with decreasing of organic matter content in dependence near to logarithmic. Qualitative difference between organic matter in treated and not treated water was observed. In not treated samples diluted to concentrations about 300–550 mgTOC/L toxic effect was 5 times higher than in not diluted waters at final stages of treatment with close content of organic matter (400-460 mgTOC/L). Toxic effect of treated water was close to that of tap water (used as control sample and for wastewater dilution).
