gleba zanieczyszczona ropą naftową - Opis:
- A laboratory experiment lasting for 90 days was conducted to examine the interaction between a remediation plant, Gossypium hirsutum, and the petroleum contaminated soil. Root indices and 9 various types of soil enzymatic activities in two separate groups were determined. Results showed that compared to the uncontaminated control, the growth of cotton roots was slightly strengthened at the pollution level of 1000 mg-kg-1, while seriously inhibited at the pollution level of 2000 mg-kg-1 and 4000 mg-kg-1. At the same pollution level, all studied soil enzymatic activities except alkaline phosphatase were markedly higher in the group with plants than in the group without plants which may indicate that the content of nutrients essential for plant growth as well as the activities of microorganisms capable of degrading contaminants were both enhanced in soils planted with cotton, therefore conducive to the increase of the overall fertility level and the degradation of pollutants in the petroleum contaminated soil.
