In Chesapeake Bay, Maryland, USA, some of the most contaminated sediments are found in the highly industrialized Baltimore Harbor–Patapsco River area. As part of a comprehensive assessment of sediment quality in this system, sediment toxicity was assessed in 10-d acute tests with the estuarine amphipod Leptocheirus plumulosus. Mean amphipod survival was significantly reduced in 7 of the 25 samp...

Some properties of compounds in degrading bacteria are required for biodegradation of contaminants to higher performance. Those strains which have a high percentage of these features are more effective at biodegradation. The present experiments were designed to measure these parameters. In this study, measurement of cell surface hydrophobic-degrading bacteria was designed which oil was separate...

The internal corrosion process in refinery environments is one of the major problems faced by hydrocarbon industry, where at least five types are found an oil primary distillation unit. This situation increases with presence high quantities contaminants within crude and processed hydrocarbons. best way to understand know parameters components that affect it apply protection metal exposed. work ...

This paper provides the results of using ground penetrating radar (GPR) method to detect hydrocarbon products (diesel and gasoline) in a controlled lab test. The work addresses environmental problem generated by uncontrolled leakage subsequent contamination plumes subsoil. Most research proposes geophysical techniques evaluate but some controversial were discussed on how it affected electrical ...

This project examined the effects of ecological factors and anthropogenic contaminants on benthic diatom communities near Casey Station, in the Windmill Islands, Antarctica. Preliminary sampling indicated significant compositional differences occurred between diatom communities in bays immediately adjacent to Casey Station and those more distant. Subsequently, a more detailed appraisal of spati...

The use of organic solvents in the chemical industry for gas-liquid absorption or liquid-liquid extraction operations is still unavoidable. search “greener” to replace fossil-based counterparts a challenge scientific community. Biocompatible ionic liquids (bio-ILs) emerged as sustainable approach development greener processes. In this work, bio-ILs based on choline common cation are evaluated p...

an aquifer located within a petroleum processing plant in moín, costa rica, suffers hydrocarbon pollution. this study aimed to determine the ability of indigenous microorganisms from this site to degrade polycyclic aromatic hydrocarbons (pahs) to evaluate the feasibility of an eventual bioremediation process. aerobic conditions were found in the aquifer, while microbial analyses of the groundw...

INTRODUCTION Underground storage tanks containing hydrocarbonbased fuels are found worldwide. Many of these tanks have leaks, allowing gasoline, diesel, oil, or other hydrocarbon materials to contaminate the surrounding soil. In 1992, only 2 million of the 5 million tanks in the U.S. were monitored for leaks. However, underground storage tanks represent only one of many sources of hydrocarbon c...
