UNASSIGNED: @entity2555 are organic compounds with highly toxic, carcinogenic, and mutagenic properties, which adversely affect the basic biological parameters of the soil, including the count of microorganisms, and the enzymatic activity. In addition to disturbances to the biological activity of the soil, @entity2556 may also exhibit toxic effects on plants. In view of the above, the study involved testing aimed at the determination of the effects of @entity2555 in a form of @entity12683 , @entity11966 , @entity10517 and @entity9435 on the count, @entity245 ( @entity245 ) index, ecophysiological (EP) diversity index of organotrophic bacteria, and the activity of soil dehydrogenases and soil urease. Moreover, an attempt was made to determine the soil's resistance based on the activity of the above-listed enzymes, and the effect of @entity2555 on seed germination and root growth was assessed by Lepidium sativum, @entity1101 , and Sinapis alba. In addition, the species of bacteria found in a soil subjected to strong pressure of @entity2555 were isolated. The experiment was performed in a laboratory on samples of loamy sand. @entity2555 were introduced into the soil in an amount of 0, 1000, 2000, and 4000  mg  kg(-1) of soil dry matter. Germination and growth of cress (L. sativum), white mustard (S. alba), and sweet @entity1101 ( @entity1101 ) were determined using Phytotoxkit tests. It was found that the tested @entity2556 increased the average colony counts of organotrophic soil bacteria; @entity9435 did so to the greatest extent (2.2-fold relative to non-contaminated soil), @entity11966 to the smallest extent (1.4-fold relative to non-contaminated soil). None of the @entity2556 changed the value of the bacterial @entity245 ( @entity245 ) index, while @entity10517 and @entity9435 increased the value of the eco-physiological (EP) diversity indicator. @entity2556 lowered the activity of the tested enzymes. The activity of dehydrogenases was dependent on a greater extent by the type of @entity7294 (54.56  %) rather than by the dose (10.64  %), while for the activity of urease, it was the opposite. The greater extent was dependent on dose (95.42  %) rather than by type (0.21  %). Dehydrogenases are characterised by greater resistance to the action of @entity2556 than urease. Based on seed germination and root growth, it has shown that S. alba is best suited, being the most vulnerable plant, while @entity1101 is the least suited. Subjecting a soil to strong pressure of @entity2556 leads to disturbances to the biological parameters of the soil, seed germination, and root growth L. sativum, @entity1101 , and S. alba.

Diversity of organotrophic bacteria, activity of dehydrogenases and urease as well as seed germination and root growth Lepidium sativum, XXXX and Sinapis alba under the influence of @entity2555 .
