“…The total PAH concentration in the Lake de Cima is far below the observed values in sediments from many sites in the world, riverine or marine, Figure 4. The Cotonou lagoon sediment samples (Benin) 47 exhibited total PAH concentrations in the range 25-1,450 ng g -1 , the Aquitaine (France) 47 in the range 4-855 ng g -1 , the Yenisey River (Russia) 48 in the range 22-810 ng g -1 , Ob River (Russia) 49 in the range 24-115 ng g -1 , Kara Sea (Russia) 49 in the range 16-94 ng g -1 , the Bayou St. John (New Orleans, USA) 50 was 10,300 ng g -1 , the Detroit and Rouge Rivers (Michigan, USA) 51 in the range 17-44,000 ng g -1 , the Atibaia River (São Paulo, Brazil) 52 in the range 10-398 ng g -1 , the Santos (São Paulo, Brazil) 13 in the range 80-42,390 ng g -1 , in Capibaribe River (Pernambuco, Brazil) 19 in the range 188-906 ng g -1 , in Xiamen Harbor (China) 53 in the range 247-480 ng g -1 .

Foram estudados sedimentos recentes dos rios Imbé, Urubu e Ururaí e da Lagoa de Cima, localizados no município de Campos dos Goytacazes, Rio de Janeiro. As frações dos hidrocarbonetos alifáticos e aromáticos foram analisadas por CG-DIC e CG-EM com o objetivo de se verificar o grau de contaminação por atividades antropogênicas ou contribuições biogênicas. A concentração total dos hidrocarbonetos alifáticos e aromáticos foram 1,2 , 2,8 , 5,8 e 4,3 µg g -1 e 74 , 30 , 722 e 340 ng g -1 para os rios Imbé, Ururaí, Urubu e Lagoa de Cima, respectivamente. O isoprenóide C 20 foi identificado no sedimento do Rio Urubu. Em nenhuma das amostras foram encontrados hopanos e esteranos. Compostos aromáticos antropogênicos, detectados ao nível de traços, foram observados somente no rio Imbé e na Lagoa de Cima (227 ng g -1 ). A razão fluoranteno/pireno foi de 4,2 para a Lagoa de Cima, sugerindo uma origem por combustão para os HPA. Este fato é consistente com a prática de queimada de plantações de cana de açúcar que ocorre freqüentemente nesta região. Um grande aporte de plantas superiores foi observado nos sedimentos dos rios Urubu, Imbé e da Lagoa de Cima; por outro lado o aporte predominante no rio Ururaí foi o aquático. A Lagoa de Cima é considerada levemente poluída por HPA, ao nível de traços, enquanto os demais sedimentos não se encontram poluídos.Sediment samples from the Imbé, the Urubu and the Ururaí rivers and from Lake de Cima were studied. These sites are located in the county of Campos dos Goytacazes, Rio de Janeiro, Brazil. Aliphatic and aromatic fractions were analyzed by GC-FID and GC-MS in order to gather information on the degree of contamination by anthropogenic activities and other biogenic contributions. Concentrations of total aliphatic and aromatic hydrocarbons were 1.2, 2.8, 5.8 and 4.3 µg g -1 and 74, 30, 722 and 340 ng g -1 in the Imbé, Ururaí, Urubu rivers and Lake de Cima, respectively. The C 20 highly branched isoprenoid alkane was identified in the Urubu sediment. There were no hopanes or steranes in any sample. Anthropogenic aromatic compounds, detected at trace levels, were observed only in the Imbé and in Lake de Cima (227 ng g -1 ). The fluoranthene/pyrene rate for Lake de Cima was 4.2, suggesting a combustion origin for the PAH. This data is consistent with the frequently sugar cane burning practice that occurs in this region. A greater input from higher plants was observed in the Urubu, Imbé and Lake de Cima sediments; on the other hand, the aquatic input predominates for Ururaí. In summary, Lake de Cima sediment is considered very slightly polluted, while the others are unpolluted. Keywords: hydrocarbons, sediments, PAH, isoprenoid, (C/N) ratios, organic matter IntroductionRecent sediments of natural waters contain variable amounts of organic matter, ranging from less than 1% up to 8% of dry sediment, 1 but are considered rich when they have more than 0.5% of organic matter. 2 It is difficult to obtain detailed information about the sources and transformations of this organic matter by deter...

“…Several studies have reported, despite the ban and restriction on the usage of some organochlorine pesticides (OCPs) since 1983 in China, the presence of elevated levels of OCPs, such as DDTs and HCHs, in seawater and coastal sediments (e.g. Zhou et al, 2001) and some river/estuarine systems (Hong et al, 1995;Chen et al, 1996;Wu et al, 1999;Zhou et al, 2000). Furthermore, DDT concentrations in marine mussels collected from China were still high, one to two orders of greater than those of other Asian countries (Nakata et al, 2002;Monirith et al, 2003;Li et al, 2001).…”

For screening 31 potential or suspected endocrine-disrupting pesticides in water and surface sediments, a multiresidue analysis method based on gas chromatography with electron capture detection (GC/ECD) was developed. Solid phase extraction (SPE) technology with Oasis Ò HLB cartridge was also applied in sample extraction. The relevant mean recoveries were 70-103% and 71-103% for water and sediment, respectively. Relative standard deviations (RSD) are 2.0-7.0%, 4.0-8.0% for water and sediment, respectively. Thirty one pesticides (a-HCH, b-HCH, c-HCH, d-HCH, hexachlorobenzene (HCB), aldrin, heptachlor, endosulfan I & II, p,p 0 -DDD, o,p 0 -DDT, p,p 0 -DDT, p,p 0 -DDE, endrin aldehyde, endosulfan sulphate, methoxychlor, hepachlor epoxide, a-chlordane, c-chlordane, dieldrin, endrin, dicofol, acetochlor, alachlor, metolachlor, chlorpyriphos, nitrofen, trifluralin, cypermethrin, fenvalerate, deltamethrin) in water and surface sediment samples from Beijing Guanting reservoir were analyzed. Concentrations of pesticides ranged from 7.59 to 36.0 ng g À1 on a dry wt. basis for sediment samples, from 279.3 to 2740 ng l À1 for pore waters and from 48.8 to 890 ng l À1 for water samples, respectively, with a mean concentration of 10.7 ng g À1 in sediment, 735 ng l À1 in pore water and 295 ng l À1 in water, respectively. The data obtained provides information on the levels and sources of endocrine-disrupting pesticides in Guanting reservoir. These results underscore the need to improved environmental protection measures in order to reduce the exposure of the population and aquatic biota to these endocrine-disrupting compounds.

“…Recent information on PCB levels in gastropods was limited and fragmentary. Lower residues of PCBs were reported in surface water and coastal sediments in China (Yuan et al 2001;Sun et al 2002), supporting the hypothesis of less use of PCBs in China (Zhou et al 2000). However, the Bohai coastline showed relatively higher PCB concentrations in bivalves except Xiamen Island (Chen et al 2002) and Qingdao (Monirith et al 2003), whereas the levels were one order lower than those from Japan (3000 ng/g lipid wt) and Russia (3200 ng/g lipid wt) (Monirith et al 2003).…”

Abstract. Mollusk samples such as bivalves and gastropods were collected from eight sampling sites along Bohai Sea coastline from northeastern China. The samples were analyzed for polychlorinated biphenyls (PCBs), polychlorinated dibenzo-p-dioxins (PCDDs), and polychlorinated dibenzofurans (PCDFs) by high-resolution gas chromatography/high-resolution mass spectrometry (HRGC-HRMS) to elucidate bioaccumulation of persistent organic pollutants in benthon. Residue levels of SPCBs and SPCDD/Fs were in the ranges of 66.1 to 583.6 ng/g and 0.9 to 15317 pg/g on a lipid-weight basis, respectively, The pollution source was identified using principal component analysis (PCA) in some coastal areas. It indicated that the typical pollution sources were characterized by PCB 3 , which was one Chinese technical product of PCBs. PCA also revealed the similarity patterns of PCBs between identical species collected from the different sites. The higher gastropod PCB concentrations were related to a former capacitor factory and the paint factories in some coastal areas, but this was not the case with the bivalves. The results of this study suggest that some gastropod species may be a potential bioindicator or ''sentinel'' organism for marine PCBs monitoring.
