Implication

Randomized trial assesses groundwater contamination from refinery water-soluble fractions, indicating varying organic compositions.

Key Points

This research aims to analyze the composition and dissolution behavior of water-soluble fractions from refined petroleum products and their impact on groundwater contamination.
Generated oil-water equilibrium WSFs from 25 refined petroleum products using a slow-stirring method.
Analyzed for total organic carbon, total petroleum hydrocarbons, volatile petroleum hydrocarbons, extractable petroleum hydrocarbons, and oxygen-containing organic compounds.
Measured the variations in dissolved organic concentrations across different product types.
Dissolved organic concentrations varied by 1–2 orders of magnitude among different petroleum products.
Gasoline and naphtha showed high total organic carbon and total petroleum hydrocarbon concentrations, primarily due to C6-C9 aromatic hydrocarbons.
Kerosene and diesel displayed significantly lower dissolved hydrocarbon concentrations, while oxygenated additives like MTBE and TAME were prevalent in gasoline-related products.
