Influence of contact time on extractability and degradation of pyrene in soils
Article Abstract:
Temporal changes in extractability of [14C]-pyrene were studied in two soils with different contents of organic matter under sterile and nonsterile conditions for a period of 24 weeks. The study is broken down into an introduction, a discussion of materials and methods used in the experiment, and a discussion of the results. Various tables accompany the article.

A distributed reactivity model for sorption by soils and sediments. 11. Slow concentration-dependent sorption rates
Article Abstract:
Research results indicate that the time needed to attain apparent sorption equilibrium by a phenanthrene probe are highly dependent on a given sorbent's aqueous phase-solute concentration and the kind of soil organic matter with which a given sorbent is associated. Results were obtained for six kerogen and shale samples and seven EPA reference soils.

Development of a Rhodococcus recombinant strain for degradation of products from anaerobic dechlorination of PCBs
Article Abstract:
The recombinant RHA1, a strain of the Gram-positive bacterium Rhondococcus sp., was constructed to grown on a PCB. It was then demonstrated that the strain would grow in nonsterile soil if the right chlorobiphenyl is available, thus completely degrading a chlorobiphenyl in nonsterile soil.
