Predictive model for estimating the extent of petroleum hydrocarbon biodegradation in contaminated soils
Article Abstract:
Factors affecting the maximum degree of the biodegradation of total petroleum hydrocarbon was examined by analyzing the solid- and slurry-phase bioremediation of different hydrocarbon types. Results revealed that the extent of the biodegradation of hydrocarbons depends largely on the molecular composition of the contaminant in the soil. In addition, biodegradation was not found to be adversely affected by the aqeuous solubility of hydrocarbon molecules.

Crude oil hydrocarbon bioremediation and soil ecotoxicity assessment
Article Abstract:
The types of hydrocarbons present in contaminated soils directly determine the effectiveness of the bioremediation techniques used to clean the soils. In fact, contaminants with polycyclic structures were the most resistant to bioremediation processes. The presence of microbial populations and nutrient fertilizer, the type of soil being remediated or the treatment techniques used were not as important in determining bioremediation effectiveness.

Phytoextraction of zinc by oat (Avena sativa), barley (Hordeum vulgare), and Indian mustard (Brassica juncea)
Article Abstract:
The success of soil contaminant removal from soil through phytoremediation depends on the selection of plant species and soil amendments. Oat, barley and Indian mustard were found to tolerate high cadmium, copper and zinc concentrations and accumulated high levels of these metals in the plant shoots. However, only indian mustard was able to effectively phytoextract zinc after the synthetic chelate EDTA was applied to the soil.
