Effect of iron on the biodegradation of petroleum in seawater.
The biodegradation of South Louisiana (SL) crude oil and the effects of nitrogen, phosphorus, and iron supplements on this process were compared in a polluted (10,900 oil degraders per liter) and in a relatively clean (750 oil degraders per liter) littoral seawater sample taken along the New Jersey coast. Without supplements, the biodegradation of SL crude oil was negligible in both seawater sa...
متن کاملIdentification of ester metabolites from petroleum hydrocarbon biodegradation in groundwater using GC×GC-TOFMS.
In an effort to understand the nature and toxicity of petroleum hydrocarbon degradation metabolites, 2-dimensional gas chromatography linked to a time-of-flight mass spectrometer (GC×GC-TOFMS) was used to conduct nontargeted analysis of the extracts of 61 groundwater samples collected from 10 fuel release sites. An unexpected result was the tentative identification of 197 unique esters. Althoug...
متن کاملToxicity of polar metabolites associated with petroleum hydrocarbon biodegradation in groundwater.
The recent study by O’Reilly et al. [1] describing the identification of 197 esters likely related to the biodegradation of petroleum hydrocarbons in 61 groundwater samples from 10 fuel release sites in California lacks evidence that these compounds have a “low toxicological profile,” which is the argument used by the authors to promote the routine use of silica gel cleanup. The detection ofmor...
متن کاملThe Effect of Urban Fuel Stations on Soil Contamination with Petroleum Hydrocarbons
Background:A critical environmental impact of the petroleum industry is the contamination of soil by oil and other related products which are highly toxic and exhibit molecular recalcitrance. Therefore, this study focused on investigating the total amount of petroleum hydrocarbons (TPHs) in soil of urban fuel stations in Hamedan City, Iran. Methods:Thirteen high traffic urban fuel stations ...
