“…Previous studies focused on the PAHs concentrations in water and SPM samples in the Wuhan section (Feng et al 2007), Three Gorges Reservoir (Deyerling et al 2014), and Poyang Lake (Zhi et al 2015) (Table 1). We found that the concentrations of PAHs in different areas of the Yangtze River have relatively large differences (Table 1).…”

Samples were collected from the middle and lower reaches of the Yangtze River, China, to study the concentrations, distributions, and compositions of 16 US-EPA priority polycyclic aromatic hydrocarbons (PAHs) in water and suspended particulate matter (SPM). We also evaluated sources of the PAHs and their potential toxicity. Total concentrations of the PAHs (ΣPAHs) in water ranged from 17.33 to 77.12 ng L −1 , and in SPM, the levels ranged from 595.91 to 2473.74 ng g −1 . Total concentrations of seven carcinogenic PAHs (ΣCPAHs) ranged from 7.63 to 13.02 ng L −1 in water and 276.55 to 1216.89 ng g −1 in SPM. PAH levels in water samples were relatively low, and those in the lower reaches were higher than in the middle reaches. SPM samples had higher levels of PAHs, especially in the lower reaches and in Dongting Lake and Poyang Lake. Principal component analysis (PCA) with multiple linear regression analysis (MLR) was performed to quantitatively characterize the PAH sources. Two factors and their contributions were identified from water samples. Coal and wood combustion accounted for 74.1 % of the PAHs, and petroleum emissions explained 25.9 % of the PAHs. Three source factors were identified from SPM samples: these were vehicular emissions (46.3 % of PAHs), wood and coal combustion (40.4 % of PAHs), and petrogenic sources (13.3 %). Ecological risk assessment indicated that a moderate undesirable impact will be caused by PAHs, and some control measures and remedial actions should be conducted.

“…Drinking water and a large amount of fishery products are taken from the middle reach of the Yangtze River. The environmental degradation of the river has occurred for decades, and PAHs are widely detected in this aquatic environment (Deyerling et al, 2014;Zhang et al, 2014b). In this study, the overlying water, SPS, and deposited sediment samples were collected from six sites in the middle reach of the Yangtze River in May, 2013, during the dry season.…”

“…Individual PAH concentrations ranged from nondetection to 2.5 pg L −1 , whereas fluoranthene was the most abundant compound. In our previous study, we investigated PAH mass fluxes within the TGR with the aid of virtual organisms and concluded that even low detected concentrations in this water body correspond to a high mass flux of PAHs in total (Deyerling et al 2014) and consequently a high total input of these organic substances into the environment. Polycyclic aromatic hydrocarbons are released into the environment mainly by partially incomplete natural and anthropogenic burning processes (EPA 2008).…”

“…The intention behind the enrichment of a large water volume was the low analyte concentrations apparent in the TGR as mentioned above. We already demonstrated in our recent study that low concentrations of polycyclic aromatic hydrocarbons (PAHs) in the reservoir correspond to high total mass fluxes in the large water body (Deyerling et al 2014). Qi et al applied this principle (among other analytes) on PPCPs (Qi et al 2014).…”

Persistent and emerging organic pollutants were sampled in September 2012 and 2013 at a sampling site in front of the Three Gorges Dam near Maoping (China) in a water depth between 11 and 61 m to generate a depth profile of analytes. A novel compact water sampling system with self-packed glass cartridges was employed for the on-site enrichment of approximately 300 L of water per sample to enable the detection of low analytes levels in the picogram per liter-scale in the large water body. The overall performance of the sampling system was acceptable for the qualitative detection of polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs), organochlorine pesticides (OCPs), perfluoroalkylic acids (PFAAs), pharmaceutical residues and polar pesticides. Strongly particle-associated analytes like PAHs and PCBs resided mainly in the glass wool filter of the sampling system, whereas all other compounds have mainly been enriched on the XAD-resin of the selfpacked glass cartridges. The sampling results revealed qualitative information on the presence, depth distribution and origin of the investigated compounds. Although the depth profile of PAHs, PCBs, OCPs, and PFAAs appeared to be homogeneous, pharmaceuticals and polar pesticides were detected in distinct different patterns with water depth. Source analysis with diagnostic ratios for PAHs revealed their origin to be pyrogenic (burning of coal, wood and grass). In contrast, most PCBs and OCPs had to be regarded as legacy pollutants which have been released into the environment in former times and still remain present due to their persistence. The abundance of emerging organic pollutants could be confirmed, and their most abundant compounds could be identified as perfluorooctanoic acid, diclofenac and atrazine among investigated PFAAs, pharmaceuticals and polar pesticides, respectively.
