Spatial and temporal distributions of polybrominated diphenyl ethers (PBDEs) in sediments the Pearl River Delta (PRD) adjacent South China Sea (SCS) southern were examined. A total 66 surface sediment samples collected analyzed to determine concentrations 10 PBDE congeners (BDE-28, -47, -66, -100, -99, -154, -153, -138, -183, -209). The BDE-209 ∑PBDEs (defined as sum all targeted except for BDE-209) ranged from 0.4 7340 0.04 94.7 ng/g, respectively. mostly <50 within range riverine coastal...
Air samples were collected in June of 2004 from four sites the city Guangzhou, a typical urban center South China, to determine levels, compositional profiles, and gas-particle distribution 11 polybrominated diphenyl ether (PBDE) congeners (BDE-28, -47, -66, -100, -99, -85, -154, -153, -138, -183, -209). The arithmetic mean atmospheric concentrations sigmaPBDEs (sum all target PBDE except for BDE-209) background comparable or slightly higher than those other places around world. BDE-209,...
Surface sediment (0-5 cm) samples were collected from the Pearl River Estuary (PRE) and adjacent northern South China Sea (SCS) in July 2002 analyzed for 25 polycyclic aromatic hydrocarbons (PAHs) 8 organochlorine pesticides (OCPs) including dichlorodiphenyltrichloroethanes (DDTs), hexachlorocyclohexanes (HCHs), heptachlor. The total PAHs OCPs concentrations 138-1100 0.18-3.57 ng/g dry weight, respectively. Compositional pattern analysis suggested that PRE derived both pyrogenic petrogenic...
Persistent halogenated compounds (PHCs), such as dichlorodiphenyltrichloroethane and its metabolites (DDTs), hexachlorocyclohexane isomers (HCHs), polychlorinated biphenyls (PCBs), polybrominated diphenyl ethers (PBDEs), decabromodiphenylethane (DBDPE), biphenyl 153 (PBB 153), were quantified in muscles of five waterbird species collected from an extensive e-waste recycling region the Pearl River Delta, South China. PCBs, at concentrations up to 1,400,000 ng/g lipid, dominant contaminants...
Brominated flame retardants (BFRs), including polybrominated diphenyl ethers (PBDEs), 1,2-bis(2,4,6-tribromophenoxy)ethane (BTBPE), decabromodiphenyl ethane (DBDPE), and biphenyls (PBBs) were found in children's toys purchased from South China. The median BFR concentrations the hard plastic 53 000, 5540 ng/g, 101.1 27.9 for total PBDEs, DBDPE, BTBPE, PBBs, respectively, which notably higher than values other toys. PBDE below threshold limit (1000 ppm) required by European Commission's...
Dechlorane Plus (DP), a highly chlorinated flame retardant, has been detected in water, sediment, and aquatic organisms reservoir the vicinity of electronic waste recycling workshops South China. The biomagnification potential DP food web was assessed compared with that polybrominated diphenyl ethers (PBDEs) polychlorinated biphenyls (PCBs). all species, concentrations 19.1−9630 ng/g lipid wt. A depletion anti-DP observed abiotic samples fraction found to be further decreased upon moving up...
Several currently used non-polybrominated diphenyl ether (PBDE) brominated flame retardants (BFRs), including hexabromocyclododecanes (HBCDs), 1,2-bis(2,4,6-tribromophenoxy)ethane (BTBPE), decabromodiphenyl ethane (DBDPE), hexabromobenzene (HBB), pentabromoethylbenzene (PBEB), and pentabromotoluene (PBT), are examined in the components of a freshwater food web from an electronic waste recycling site, South China. All these BFRs detectable web, with average concentrations 13.9−868, 1.71−518,...
Short-chain and medium-chain chlorinated paraffins (SCCPs MCCPs) were measured in sediments from ponds, rivers tributaries, an estuary, as well a sediment core the Pearl River Delta (PRD), South China, to comprehensively investigate spatial temporal distributions of CPs. The concentrations SCCPs MCCPs varied 320 6600 ng/g 880 38,000 ng/g, respectively. Elevated CP found pond (means 2800 21,000 for e-waste recycling area river 1200 3900 highly industrialized areas. significant positive...
Riverine runoff is an important mode to transport anthropogenic pollutants from terrestrial sources oceans. Polybrominated diphenyl ethers (PBDEs) were measured in riverine samples the eight major outlets within Pearl River Delta (PRD), China, economically fast developing region housing a vast number of electronics manufacturing and assembling plants. The sigma 17PBDEs (sum 17 BDE congeners, i.e., BDE-28, -47, -66, -85, -99, -100, -138, -153, -154, -183, -196, -197, -203, -206, -207, -208,...
Birds of prey from Northern China (Beijing area) were examined for polybrominated diphenyl ethers (PBDEs). A total 47 specimens eight different species analyzed. Muscle and liver analyzed separately each bird. Kidneys pooled by species. Common kestrels exhibited the highest PBDE levels (mean muscle concentrations 12 300 200 ng/g lipid weight, respectively), with maxima in an individual bird 31 700 40 900 lw liver. Congener profiles differed between some species, but generally dominated more...
The recycling of electrical and electronic waste(e-waste) in developing countries has attracted much attention as a significant source brominated flame retardants (BFRs).Gaseous particle-bound BFRs were measured the atmosphere at e-waste rural sites southern China during 2007-2008. annual average concentrations air 3260 ± 3370 219 192 pg/m³ for polybrominated diphenyl ethers (PBDEs) 546 547 165 144 non-PBDE sites,respectively.
