“…6. Comparing with the sediments, PAHs in soils was low in Fluo, Pyr, and BaP, but enriched with BbF, BghiP, and Ind, which indicated more contribution of coking and vehicular sources to PAHs in soils than to those in sediments (Bzdusek and Christensen 2004;Zuo et al 2007). Compared with sediment, SPM analysis could only explain a short-term contamination source especially in wet season (Shi et al 2007).…”

“…This might reflect the more complex PAHs input sources to these two drainage canals (Mai et al 2003). PAHs sources in surface soil and dustfall has been identified and apportioned (Zuo et al 2007;Wu et al 2005). For soil samples in the urbansuburban zone, 37% PAHs was from a combined source of coal and petroleum, 26% was from a combined source of coking and biomass, and 23% was from incineration (Zuo et al 2007).…”

Polycyclic aromatic hydrocarbons (PAHs) partitioning among dissolved phase, suspended particulate matter, pore water, and sediment was studied in one moderately contaminated river (Yongding New River) and two highly contaminated drainage canals (South Drainage Canal and North Drainage Canal) of Tianjin, China. PAHs concentrations in sediment (ranged from 0.2 to 195 μg/g) showed positive relations with both total organic carbon contents (ranged from 0.7% to 31.1%, dw) and black carbon contents (ranged from 0.1% to 2.1%, dw) in the sediments. Moreover, most of the measured organic carbon normalized partition coefficients of PAHs in the three streams were 0.76 to 1.54 log units higher than the predicted values. These indicated that strong and nonlinear sorption

“…This group of PAHs is typically derived from combustion of diesel (Tavares et al, 2004;Bixiong et al, 2006). The second component responsible for 15% of the total variance included FLR and PYR, which are indicators of coal/lignite combustion (Zuo et al, 2007). The third component was responsible for 12% of total variance, and consisted of ACP, BaA, CHR, and BaP representing mixed sources from both diesel and coal/lignite combustion (Bixiong et al, 2006;Kulkarni et al, 2000).…”

The sources and historical deposition of 16 polycyclic aromatic hydrocarbons (PAHs) were investigated in dated sediment cores from the Pichavaram mangrove-estuarine complex. The ΣPAH flux in mangrove and estuarine sediments are 0.064 ± 0.031 μg/cm 2 /yr and 0.043 ± 0.020 μg/cm 2 /yr, respectively. The PAH flux in sediments increases up-core coinciding with rapid urbanization since the 1970s. The flux shows a decrease in recent years (since 1990) coinciding with less riverine discharge, and perhaps more effective implementation of environmental regulations. The sediments are dominated by low molecular weight PAHs suggesting anthropogenic input. Ratios of specific PAH isomer pairs suggest higher input of petrogenic over pyrogenic derived PAHs. Notably, the deposition of high molecular weight PAHs increase in mangrove surface sediments was due to lignite and firewood combustion. Because of their overall low concentrations in sediments it is unlikely these PAHs pose an immediate ecological hazard.

Abstract-Forty-five sediment samples collected from Dongjiang River, which drains one of the most industrialized and urbanized regions in South China, were analyzed for 19 linear alkylbenzene (LAB) components. The sample dry weight-based concentrations of total LABs (SLAB) ranged from 1.5 to 410 ng/g. Comparison of the relative abundances of n-dodecylbenzenes (or C 12 -LABs) and internal to external ratio (I/E) values in riverine sediment, wastewater, and sediment samples from the outfalls of paper mills, as well as three brands of domestic detergents obtained from the present and previous studies, implicated the occurrence of untreated wastewater in the sampling sites. Levels of SLAB were significantly linear correlated with those of total organic carbon (TOC) but not with those of polycyclic aromatic hydrocarbons. Multiple linear regression integrated principal component analysis indicated that 56% of LABs in wastewater in the study area were treated, but the extent of degradation of LABs was low. Finally, it is proposed that ineffective law enforcement and loopholes in the current regulations for wastewater discharge account for the substantial amount (44%) of untreated wastewater discharged in the study region.
