However, model studies regarding BFR food‐chain accumulation are scarce. In the present study, the accumulation of hexabromocyclododecane and brominated diphenyl ethers (BDEs) 47, 153, 154, and 183 in benthivorous barbel (Barbus graellsii) and pelagic bleak (Alburnus... 2009-12-09T00:00:00Z http://www.setacjournals.org/details/journalArticle/547791/Fieldbased_effects_measures.html 2009-12-09T00:00:00Z http://www.setacjournals.org/details/journalArticle/547597/Use_of_a_parallel_artificial_membrane_system_to_evaluate_passive_absorption_and_.html Abstract A parallel artificial lipid membrane system was developed to mimic passive mass transfer of hydrophobic organic chemicals in fish. In this physical model system, a membrane filter–supported lipid bilayer separates two aqueous phases that represent the external and internal aqueous environments of fish. To predict bioconcentration kinetics in small fish with this system, literature absorption and elimination rates were... 2009-12-09T00:00:00Z http://www.setacjournals.org/details/journalArticle/547649/No_longer_just_deja_vu.html 2009-12-09T00:00:00Z http://www.setacjournals.org/details/journalArticle/547549/Characterizing_sediment_acid_volatile_sulfide_concentrations_in_European_streams.html Abstract Sediment acid volatile sulfide (AVS) concentrations were measured in wadeable streams of a wide variety of ecoregions of western Europe (84 sites in 10 countries and nine ecoregions) to better understand spatial distribution and ecoregion relationships. Acid volatile sulfide has been shown to be a major factor controlling the bioavailability and toxicity of many common trace metals, such as Cd, Cu, Ni, Pb, and Zn. Sediment... 2009-12-09T00:00:00Z http://www.setacjournals.org/details/journalArticle/547865/Erratum.html 2009-12-09T00:00:00Z http://www.setacjournals.org/details/journalArticle/548705/Aqueous_photolysis_of_82_fluorotelomer_alcohol.html Abstract The 8:2 fluorotelomer alcohol (8:2 FTOH) was photodegraded in aqueous hydrogen peroxide solutions, synthetic field water (SFW) systems, and Lake Ontario (Canada) water samples. It was found to undergo indirect photolysis, with the data suggesting that the hydroxyl radical was the main degradation agent and that nitrate promoted photolysis whereas dissolved organic carbon inhibited it. The half‐lives of 8:2 FTOH were 0.83 ±... 2009-12-09T00:00:00Z http://www.setacjournals.org/details/journalArticle/548633/Body_distribution_of_trace_elements_in_blacktailed_gulls_from_Rishiri_Island_Jap.html Abstract Body distribution and maternal transfer of 18 trace elements (V, Cr, Mn, Co, Cu, Zn, Se, Rb, Sr, Mo, Ag, Cd, Sb, Cs, Ba, Hg, Tl, and Pb) to eggs were examined in black‐tailed gulls (Larus crassirostris), which were culled in Rishiri Island, Hokkaido Prefecture, Japan. Manganese, Cu, Rb, Mo, and Cd showed the highest levels in liver and kidney, Ag, Sb, and Hg in feather, and V, Sr, and Pb in bone. Maternal transfer rates of trace... 2009-12-09T00:00:00Z http://www.setacjournals.org/details/journalArticle/548563/Comment_on_the_longterm_fate_of_polychlorinated_biphenyls_in_San_Francisco_bay_U.html 2009-12-09T00:00:00Z http://www.setacjournals.org/details/journalArticle/548499/Mentoring_early_career_professionals_in_the_society_of_environmental_toxicology_.html 2009-12-09T00:00:00Z http://www.setacjournals.org/details/journalArticle/548449/Environmental_fate_of_the_antifouling_compound_zinc_pyrithione_in_seawater.html Abstract To perform a thorough risk assessment of the new antifouling compound zinc pyrithione (ZnPT2), additional information regarding the fate of the compound is needed. The present study examined the recovery and transchelation of ZnPT2 in controlled laboratory experiments, photodegradation experiments, and a fate study in a large‐scale field experiment. Chemical analyses were performed using a newly developed method for simultaneous... 2009-12-09T00:00:00Z http://www.setacjournals.org/details/journalArticle/548369/Dissipation_kinetics_and_mobility_of_chlortetracycline_tylosin_and_monensin_in_a.html Abstract A robust high‐throughput method was refined to extract three growth‐promoting antibiotics, tylosin (TYL), chlortetracycline (CTC), and monensin (MON), from soil. Analysis was performed by electrospray liquid chromatography tandem mass spectrometry. Soil dissipation rate studies were performed in a farm field soil for antibiotics applied with and without manure. Tylosin, CTC, and MON followed first‐order dissipation kinetics... 2009-12-09T00:00:00Z http://www.setacjournals.org/details/journalArticle/548289/Sorption_kinetics_of_toluene_in_humic_acid_A_computational_approach.html Abstract Molecular dynamics, a computational technique aiming to describe the time‐dependent movement of molecules, has been applied to study the sorption kinetics of volatile organic contaminants in soil organic matter. The molecular dynamics simulation results obtain reasonably accurate estimates of diffusion rates and activation energy of the penetration of a volatile organic compound molecule into a model humic substance.

Perchlorate at an initial concentration of 10 μM was reduced quantitatively to chloride in 3 d after a lag phase of 2 d in sediment slurries amended with lactate. Raising the initial... 2009-12-09T00:00:00Z
