“…The chemical DBDPE, which is used as a replacement for BDE 209, was detected in all the sediment samples, thus indicating that this contaminant was prevalent in river and marine sediments in northern China. It is note worthy that concentrations of DBDPE in most of the sediments were higher than levels of BDE 209 in this study, and this phenomenon was also seen in other studies of marine, sludge, and sediment samples (Baron et al, 2013;Lee et al, 2014c;Zheng et al, 2015). The concentrations of DBDPE in 51 coastal and 3 river sediment samples ranged from 1.13 to 49.9 ng g À1 dw (mean: 29.4 ng g À1 dw) and from 0.16 to 39.7 ng g À1 dw (mean: 2.09 ng g À1 dw), respectively.…”

“…In comparison, DBDPE concentrations (1.13 ng g À1 dw at site H1, 37.2 ng g À1 dw at site H2, and 49.9 ng g À1 dw at site H3) in the three river sediment samples were one to two orders of magnitude lower than those in the Dongjiang River (n.d. e 1728 ng g À1 dw) , which runs across the major electronic/electrical manufacturing base of the Pearl River Delta (PRD) . The DBDPE concentrations (0.16e39.7 ng g À1 dw) in all coastal sediments in this study were similar to those in the Pearl River estuary (PRE) (n.d. e 30.5 ng g À1 dw) and Ebro and Llobregat River basins (n.d e 31.5 ng g À1 dw) (Baron et al, 2014), but higher than those in marine sediments, such as those from the Yangtze River Delta (0.18e1.57 ng g À1 dw) , Stockholm coast in Sweden (n.d. e 11 ng g À1 dw) (Ricklund et al, 2010), three bays in South America (n.d. e 2.26 ng g À1 dw) (Baron et al, 2013), and the western Arctic Ocean (n.d. e 0.45 ng g À1 dw) (Cai et al, 2012). The DBDPE concentrations in marine sediments of northern China were at a moderate level, comparatively.…”

a b s t r a c tThe distribution characteristics and potential sources of polybrominated diphenyl ethers (PBDEs) and alternative brominated flame retardants (aBFRs) were investigated in 54 surface sediment samples from four bays (Taozi Bay, Sishili Bay, Dalian Bay, and Jiaozhou Bay) of North China's Yellow Sea. Of the 54 samples studied, 51 were collected from within the four bays and 3 were from rivers emptying into Jiaozhou Bay. Decabromodiphenylethane (DBDPE) was the predominant flame retardant found, and concentration ranged from 0.16 to 39.7 ng g À1 dw and 1.13e49.9 ng g À1 dw in coastal and riverine sediments, respectively; these levels were followed by those of BDE 209, and its concentrations ranged from n.d. to 10.2 ng g À1 dw and 0.05e7.82 ng g À1 dw in coastal and riverine sediments, respectively. The levels of DBDPE exceeded those of decabromodiphenyl ether (BDE 209) in most of the samples in the study region, whereas the ratio of DBDPE/BDE 209 varied among the four bays. This is indicative of different usage patterns of brominated flame retardants (BFRs) and also different hydrodynamic conditions among these bay areas. The spatial distribution and composition profile analysis indicated that BFRs in Jiaozhou Bay and Dalian Bay were mainly from local sources, whereas transport from Laizhou Bay by coastal currents was the major source of BFRs in Taozi Bay and Sishili Bay. Both the P PBDEs and P aBFRs (sum of pentabromotoluene (PBT), 2,3-diphenylpropyl-2,4,6-tribromophenyl ether (DPTE), pentabromoethylbenzene (PBEB), and hexabromobenzene (HBB)) were at low concentrations in all the sediments. This is probably attributable to a combination of factors such as low regional usage of these products, atmospheric deposition patterns, coastal currents transportation patterns, and degradation processes for higher BDE congeners. This paper is the first study that has investigated the levels of DBDPE in the coastal sediments of China's Yellow Sea.

“…These high concentrations in sediments can be associated with its extensive use in personal care products, especially sunscreens (Amine et al, 2012;Gago-Ferrero et al, 2011a). However, OC was not found in all studies, which suggests that the production and use profiles of UV-filters are different among countries (Barón et al, 2013).…”

“…These extraction techniques yielded high recoveries like conventional solid-liquid extraction (SLE) using ultrasounds with 65 (BP8) to 125% (BP) (Jeon et al, 2006), pressurized liquid extraction (PLE) with 58 (BP1) to 128% (IMC) (Gago-Ferrero et al, 2011;Rodil et al, 2008), and selective pressurized liquid extraction (SPLE) from 85 (OC) to 125% (BP3) (Barón et al, 2013). Solid-phase extraction (SPE) used as a cleanup also yields high recoveries, ranging from 70 to 125% (Kameda et al, 2011), applied to sediments, and 88 to 105% applied to soils .…”

UV-filters are a group of compounds designed mainly to protect skin against UVA and UVB radiation, but they are also included in plastics, furniture, etc., to protect products from light damage. Their massive use in sunscreens for skin protection has been increasing due to the awareness of the chronic and acute effects of UV radiation. Some organic UV-filters have raised significant concerns in the past few years for their continuous usage, persistent input and potential threat to ecological environment and human health. UV-filters end up is wastewater and because wastewater treatment plants are not efficient in removing them, lipophilic compounds tend to sorb onto sludge and hydrophilics end up in river water, contaminating the existing biota. To better understand the risk associated with UV-filters in the environment a thorough review regarding their physicochemical properties, toxicity and environmental degradation, analytical methods and their occurrence was conducted.Higher UV-filter concentrations were found in rivers, reaching 0.3 mg/L for the most studied family, the benzophenone derivatives. Concentrations in the ng to µg/L range were also detected for the paminobenzoic acid, cinnamate, crylene and benzoyl methane derivatives in lake and sea water.Although at lower levels (few ng/L), UV-filters were also found in tap and groundwater. Swimming pool water is also a sink for UV-filters and its chlorine by-products, at the µg/L range, highlighting the benzophenone and benzimidazole derivatives. Soils and sediments are not frequently studied, but concentrations in the µg/L range have already been found especially for the benzophenone and crylene derivatives. Aquatic biota is frequently studied and UV-filters are found in the ng/g-dw range with higher values for fish and mussels. It has been concluded that more information regarding UVfilter degradation studies both in water and sediments is necessary and environmental occurrences should be monitored more frequently and deeply.

“…Residues of more polar organic UV filters have been found in all kind of water matrices including tap water (Díaz-Cruz et al, 2012). Because of the high lipophilicity and poor biodegradability of many of them, they end up in sewage sludge during wastewater treatment (Gago-Ferrero et al, 2011a), and accumulate in sediments (Barón et al, 2013;Gago-Ferrero et al, 2011b), and in biota (Buser et al, 2006;Fent et al, 2010, Gago-Ferrero et al, 2013bGago-Ferrero et al, 2015). It has been suggested that biomagnification may occur through the food web (Fent et al, 2010).…”

This work presents the occurrence and fate of selected personal care products (PCPs) in the urban river-groundwater interface. To this end, urban river and groundwater samples were collected in Sant Adrià del Besòs (NE of Spain) and a total of 16 PCPs were analyzed including benzophenone derivatives, camphor derivatives, p-aminobenzoic acid derivatives, triazoles and parabens in three different campaigns (from May 2010 to July 2014). These compounds reach the aquifer through the recharge of Besòs River that receives large amounts of effluents from waste water treatment plants.Results shown that most of compounds were not or barely detected (maximum concentrations around 200 ng/L) in groundwater samples during the different sampling campaigns. Only two triazoles, namely benzotriazole (BZT) and methyl benzotriazol (MeBZT) were found at high concentrations in groundwater samples (maximum concentration around 2000 ng/L). The fate of PCPs in the aquifer was assessed using mixing analysis considering the seasonal variability of the Besòs River. Overall, measured groundwater concentrations were significantly much lower than those estimated by the mixing of the river water. This observation suggested that most of the PCPs are naturally removed when river water infiltrates the aquifer. However, some compounds were more persistent in the aquifer. These compounds were in descending order: the triazoles BZT and MeBZT followed by the camphor derivative 4MBC and the paraben MePB. The measured concentrations allowed us to assess the environmental risk posed by the selected UV-filters and parabens in the river and groundwater samples. Hazard Quotients (HQs) for different aquatic species were calculated in order to characterise the ecotoxicity potential of the studied compounds in the river-groundwater interface.HQ values were always below 1 indicating that at the concentrations observed in the surface or aquifer water of Besòs River these compounds pose no risk to the selected aquatic organisms.
