Most industrialized societies depend on the petroleum industry.
Imports of petroleum and petroleum products declined by 23.9 %.
The editors are both experienced petroleum geologists, who have worked hard to ensure an even standard of treatment.
The residual total petroleum hydrocarbons present at the site were unresolved complex material.
Sampling of soil and water for an assessment of contamination by heavy metals and petroleum hydrocarbons was also carried out.
Some of these sites are where the storage or use of petroleum hydrocarbons was likely to have been common when the station was inhabited.
Unused tanks of petroleum, materials containing asbestos, chemicals for experimentation, and thousands of other items were left behind.
If the nuclear status was unclear, the oocytes were mounted on slides that had been prepared with petroleum jelly/paraffin wax supporting droplets.
Given the large quantity of petroleum-contaminated soil present, remediation processes that can be carried out in situ are likely to be the preferable clean-up options.
It is the realm of bioremediation where the greatest advances are being made for treating petroleum-contaminated soils in cold regions.
