Biodegradation of styrene in samples of natural environments
Article Abstract:
The biodegradation, sorption and volatilization of styrene in natural and polluted environments was measured. The highest rate of microbial mineralization occurred in such environments as sewage and organic soils, but the lowest mineralization rate occurred in such environments as waterlogged soil and aquifer sand. In addition, styrene volatilized quicker from lake water than from soil. Styrene sorption in organic and mineral soils reached 79% in the first 30 hours.

Effect of aging of chemicals in soil on their biodegradability and extractability
Article Abstract:
A study was conducted to determine if the duration of time that organic chemicals remain in the soil affects the chemicals' biodegradability and ease of extraction from the soil. The study involved aging phenanthrene and 4-nitrophenol in sterilized muck and loam. The results showed that organic chemicals as exemplified by phenanthrene and 4-nitrophenol became increasingly resistant to extraction and biodegradation as time passed.

Effect of varying the rate of partitioning of phenanthrene in nonaqueous-phase liquids on biodegradation in soil slurries
Article Abstract:
The impact of different phenanthrene partitioning rates in nonaqueous-phase liquids (NAPLs) to water on biodegradation was evaluated. Rapid partitioning rates were observed in soil slurries or aquifer solids that were conditioned by the NAPL. Biodegradation was prevented by applying surfactant that generated partitioning increases. Hydrophobic compound sorption levels were conditioned primarily by organic matter content.
