Abstract

In work toxicity questions the zoloshlakovykh of the waste which is formed when burning coal at various power enterprises and underwent additional processing when leaching from them rare-earth metals are considered. It is established by biotesting that at certain doses the zoloshlakovykh of waste they have no negative impact on development. As showed researches when entering into the soil of a kek of zoloshlak in quantity to 1 % the total of mesophilic and facultatively anaerobic microorganisms didn't change and remained at the level of a control sample. This quantity of a kek had no the inhibiting impact and on growth of test culture of oats of sowing Avena sativa. At increase of concentration of a kek in the soil gradual decrease in total of soil microorganisms was noted. Thus it was noted as well reduction of a morphological variety of soil microflora. Thus also inhibiting influence on growth and a korneobrazovaniye of oats sowing is revealed.
