| Summary: | A major difficulty in applying bioremediation to field sites biodegradation in these samples. Total ion chromatograms biodegradation to occur. Low bioavailability may account for biodegradation. Bioavailability is important for consortium of biosurfactant organisms in relation to PAH contaminated soil. The effectiveness of EPA Seal Beach degradation. Also the use of 17a 21 b hopane as an internal determines any change in the ratio of molecular Markers. Different ratios of molecualr markers are tested. Linear due to the large spatial heterogeneity of the oil content in from each of the samples from both areas illustrate a highly is based on the hypothesis that molecular markers can be used is the quantification ofin situ bioremediation. This study life constants calculated from these ratios, assuming first- markers decreases the PAH concentration variability in the mass balance indicator is compared to a high molecular weight normalized PAH concentrations over time show high variability of the slope for each fertilizer and control areas. Non of two different markers, a ratio can be formed which will one marker is used as a conservative mass tracer. This order degradation, seem to be unrealistic estimates for PAH benzo(gh/)perylene and to some alkylated homologous. polycyclic aromatic hydrocarbons (PAHS) at a Bunker C quantify the level and degree of biodegradation, given that regression is performed to determine the coefficients for the relation of a control is compared. using an EPA Seal Beach research was conducted to evaluate in situ biodegradation of samples. Some of the PAH/hopane ratios show statistically significant decreases over time for the control plots. Half- slope and the intercept. The slope of the equation Statistical tests are performed to analyze the significance the lack ofbioremediation at this site. the soil. Normalizing the data by using ratios of molecular to quantify in situ biodegradation. By using concentrations treatment with a consortium of biosurfactant bacteria in weathered oil, that did not markedly change over the 1 1 weeks of the experiment, indicating little or no |
