Sources and fates of aromatic compounds in urban stormwater runoff

Pyrolysis and combustion of waste lubricant oil from diesel cars: Decomposition and pollutants

“…Misuse of these oils can cause serious environmental damages. Many studies [2][3][4][5][6] have reported the high concentrations of PAHs in sewage effluents and urban runoffs are due to contamination by waste lubricant oils.…”

Adsorption of Dibenzothiophene on Marine Sediments Treated by a Sequential Procedure

“…The linear partition coefficients the partitioning of a neutral organic compound between sedi-(K p ) and correlation coefficients (r) for the fit of the data ment organic matter and water should correlate well with to Eq. [1] are given in Table 3. its partitioning between water and an immiscible organic Many researchers have evaluated the sorption of hydrophobic organic contaminants on natural sediments (7, solvent. Karickhoff et al (18) found a significant relation- the organic carbon content of the sediments was undiminished after treatment with the acetate buffer (30).…”

“…Bates et al (3,4) quantitatively char-correlates well with the octanol-water partition coefficient acterized organic sulfur compounds in marine sediments and (K ow ) through a linear free energy relationship: 1 To whom correspondence should be addressed.…”

“…Thus the partition coefficient of a given hydrophobic coal, airborne particulates, and storm water runoff, and in compound can be expressed in terms of the organic carbon sediments and organisms (1)(2)(3)(4)(5)(6). The carcinogenic and content of the sediment: harmful properties of dibenzothiophene have led to much interest (7)(8)(9)(10)(11)(12)(13)(14)(15)(16)).…”

Quantifying the quality and sampling time of oil and grease in urban stormwater runoff

“…The sources of O&G in industrial catchment may come from the oil leakage from truck, workshop and illegal discharges from food processing factories (Chow and Yusop, 2014a). MacKenzie & Hunter (1979) and Ellis & Mitchell (2006) stated that crankcase oil emissions from vehicles are the major contributor to the oil and grease pollution in the urban stormwater runoff. Studies by CERS (2000) and Pitt et al (2004) had compared the O&G concentration from residential, commercial and industrial sites in USA, and they found the similar results that industrial site exhibited the highest concentration for O&G. According to OEHHA (2006), the relatively higher oil and grease levels found at industrial sites may be related to the use of petroleum products or food processing activities at the factories.…”
