“…Such humps are frequently encountered in petroleum-polluted sediments (4, 7, 9, 25,26) and are often attributed to weathered and/or microbially degraded petroleum residues. However, they are also characteristic of refined products such as lubricating and fuel oils (3,6,7,27) and may occur as the microbial decomposition and resynthesis products of biogenic materials (28).…”

“…In 1977, the smelters in Sudbury daily emitted about 2.6 tons of Ni, 2.6 tons of Cu, 0.7 tons of Pb, and 6.3 tons of Fe (26); the daily outpouring of 2500 tons of S02 from the 381-m superstack makes it the single largest point source of this pollutant in the world (26). It has been estimated (27) that about 40% of the Cu and 70% of the Ni emitted are deposited in the immediate vicinity of Sudbury. The area around Sudbury thus represents a unique "laboratory" for studying the long-term impacts of airborne pollutants on aquatic ecosystems.…”

Hydrocarbons isolated from southern California municipal wastewaters were analyzed by high-resolution gas chromatography and computer-assisted gas chromatography-mass spectrometry. Most of the hydrocarbons (56-77%) are not chromatographically resolvable and probably derive from petroleum products such as lubricating oils. Normal, iso-, and acyclic isoprenoid alkanes along with alkylcyclohexanes and numerous series of substituted benzenes and polycyclic aromatic hydrocarbons compose the major fraction of the resolvable hydrocarbons. Polycyclic terpenoids occur as trace constituents and appear also to be of ancient, not recent biosynthetic, origin.However, the virtual absence of 17 ( ),18 ( ),21ß( )-28,30-dinorhopane, a specific marker of California oils, indicates that locally produced petroleum is, at most, a minor contributor to these wastewaters. A homologous series of long-chain alkylbenzenes presumably derived from the LAS-type detergents was identified. These compounds seem to be abundant and ubiquitous domestic wastewater constituents that might be exploited as anthropogenic waste tracers in the marine environment.

“…We found a similar pattern in our samples, particularly during the later stages of the storm; however, n-alkanes, not generated to any great extent in combustion experiments (26), are quite abundant in stormwater samples. Dewaxed lubricating oils and transmission fluids consist essentially of high molecular weight UCMs with no detectable normal alkanes (27). Thus, the high molecular weight mode of the UCM which dominated the hydrocarbons in samples collected during later stages of the storm may have its origin in any combination of these materials.…”

Problem statement: Water detection in hydrocarbon emulsions represents a serious challenge in petroleum production industry. The elemenation of measurment noises is also desired. Approach: In this study, a systematic and an applicable method of water detection in hydrocarbon emulsion is achieved using thermoacoustic effect. A Kalman filter is applied to correct measurement errors and to improve accuracy. Results: The study focused on sensing the presence of water in kerosene using the established correlation between the content of hydrocarbon emulsion and the characteristics of the acoustic wave generated by inundation of a heated rod in the emulsion. The implemented filteration enhanced the peromance of the measurment system. Conclusion: This approach was tested experimentally and showed that the produced acoustic signal can be utilized as an informative parameter in quality control schemes of petrochemical oil products
