This article shows how soil contamination with oil leads to a significant decrease in the values of its biological properties. High levels of induction of the alternating magnetic field intensified oil toxic effects
The main contribution to the soil biological properties change in the combined pollution with lead and an alternating magnetic field makes lead pollution. Contribution of the interaction of factors of 20-30%. The contribution of the alternating field was
insignificant or unreliable. Black soil and brown forest soils are similar in degree of resistance to the combined pollution. Grey sands have less stability
In the article, we have proposed regional environmental standards for heavy metals, oil and oil products in the main soils of southern Russia
In the article, we have studied the effect of lead contamination, an alternating magnetic field, their combination on such groups of soil microorganisms, as ammonifying, amylolytic, nitrogen-fixing bacteria, and micromycetes. The pollution had a significant and different effect on the number of soil microorganisms. The nature and extent of this effect varied depending on the level of impact of each factor, and they were not linear
We have investigated the influence of nickel oxide in
the amount 100, 1000 mg/kg of the soil (1, 10 MPC),
combined with the influence of variation magnetic field
with induction of 50, 100 and 650 μT power frequency
of 50 Hz on the enzyme activity and phytotoxity of the
southern chernozem. We have established significant
reduction of enzyme activity of catalase and length of
roots after the influence of the variation of magnetic
fields. Pollution by nickel as an independent factor
caused stimulation of enzyme activity of a
dehydrogenaze and length of roots of radish. The
greatest inhibition of the activity of all indicators was
observed at joint influence of magnetic fields and
pollution by nickel of concentration of 1 maximum
permissible concentration (1 MPC). Enzyme activity of
dehydrogenaze was significantly stimulated (p
In the model experiments we studied the effect of combined action of chemical pollutants (PbO 1,000 mg / kg oil 5% by weight of soil) and microwave radiation (SHF radiation) with a capacity of 450 and 800 W (duration 1 minute) on the enzymatic activity, the number of microorganisms and indicators of phytotoxicity of an ordinary black soil. We found that the combined effect is systemic, rather than a simple summation of the effects of individual pollutants, shown no direct proportion between the power of the microwave radiation and its biological effect in the combined pollution
We propose a method of biodiagnostics of soil resistance to chemical pollution and its regulation on the degree of violation of the ecological functions of soil based on the definition of the integral indicator of biological state (IIBS) of the soil. The comparative assessment of the stability of the major soils of the south Russian to chemical pollution are considered in this article
In the article we have investigated the influence of nickel oxide in the amount of 100, 1000 mg/kg of the soil (1, 10 MPC), combined with the influence of an alternating magnetic field of induction of 50, 100 and 650 µT power frequency of 50 Hz on the biological
properties of alkalinity black soil
