Phytoremediation of Hydrocarbon-Contaminated Soils

Angebote / Angebote:

Interest in phytoremediation as a solution for contaminants in groundwater and soil has exploded. The project documented in "Phytoremediation of Hydrocarbon Contaminated Soils" presents innovative technology for environmental clean up using in situ treatment. It describes the results of a field study focusing on hydrocarbon contamination, especially polynuclear aromatic hydrocarbons, in surface and near surface soils. The field demonstration used soils contaminated with aged diesel fuels. The random block design enabled the investigators to test the statistical difference in the effects of different vegetated and unvegetated treatments. They tested the degradation of diesel and polynuclear aromatic hydrocarbon components in plots containing three different vegetation treatments, two grasses and a legume, and a non-vegetated control. Part one of the monograph gives a complete and thorough account of the results of the field study. Part two covers the design and potential costs of a full-scale implementation of the demonstration system as well as the performance and potential application of the new technology. The information given on the niches and limitations of the technologies allows for a more informed selection of remedial solutions for environmmental clean up.
