Low-resolution mass spectrometric relative response factors (RRFs) and relative retention times (RRTs) on two common gas chromatographic stationary phases for 87 polychlorinated dibenzofurans

Autor: Mats Tysklind, Kjell Lundgren, Christoffer Rappe

Publikováno v: Chemosphere. 55:983-995

All 87 tetra- to octa-chlorinated dibenzofurans (PCDFs) were analysed using high-resolution gas chromatography/low-resolution mass spectrometry (HRGC-LRMS). The mass spectrometer was operated in two different modes: electron ionisation (EI), and nega

Polychlorinated biphenyls (PCBs) and their congener-specific accumulation in edible fish from the Gulf of Gdańsk, Baltic Sea

Autor: Christoffer Rappe, L. Strandberg, Jerzy Falandysz, Barbara Wyrzykowska, Tomasz Puzyn

Publikováno v: Food Additives and Contaminants. 19:779-795

Concentrations and composition profiles of polychlorinated biphenyls (PCBs) were investigated in composite samples of 10 species of edible fish from the Gulf of Gdańsk, in the southern part of the Baltic Sea, Poland, to understand the status of cont

Discrimination and thermal degradation of toxaphene compounds in capillary gas chromatography when using split/splitless and on-column injection

Autor: Peter Haglund, Hans-Rudolf Buser, Christoffer Rappe, Markus Müller, Thomas Poiger

Publikováno v: Chemosphere. 41:473-479

Technical toxaphene and a 22-component Reference Mixture were analyzed using capillary gas chromatography with split/splitless injection (SSL) and on-column injection (OC). In both techniques, electron-capture, negative ionization mass spectrometry (

Autor: Dag Broman, Carina Näf, Cecilia Bandh, Christoffer Rappe, Rasha Ishaq, Bert van Bavel, Per-Anders Bergqvist, B. Strandberg

Publikováno v: Chemosphere. 40:1205-1211

Surface sediment, amphipods (Monoporeia affinis), isopods (Saduria entomon) and fourhorn sculpins (Oncocottus quadricornis) were collected at two coastal stations in the Gulf of Bothnia, one in the Bothnian Bay and the other in the Bothnian Sea. The

Pressurised hot water/steam extraction of polychlorinated dibenzofurans and naphthalenes from industrial soil

Autor: Christoffer Rappe, Bert van Bavel, Kari Hartonen, Marja-Liisa Riekkola

Publikováno v: The Analyst. 124:1351-1354

Unique solvent properties of water, which can be changed by adjusting the temperature, were fully exploited to extract low polarity organic pollutants from soil samples. Solubility enhancement of the non-polar compounds due to the temperature increas

Tris(4-chlorophenyl)methane and Tris(4-chlorophenyl)methanol in Sediment and Food Webs from the Baltic South Coast

Autor: Christoffer Rappe, L. Strandberg, B. Strandberg, Jerzy Falandysz

Publikováno v: Environmental Science & Technology. 33:517-521

Tris(4-chlorophenyl)methane (TCPM-H) and tris(4-chlorophenyl)methanol (TCPM-OH) were identified and quantified in fishes (4.1-37 ng/g lipids), fish-eating birds (120-630 ng/ g), and marine mammals (13-31 ng/g) from the southern part of the Baltic Sea

Soxhlet extraction parameters’ influence on the recovery of polychlorinated dibenzo‐p‐dioxins and dibenzofurans (PCDD/F) from a sediment, and artifact formation of PCDD

Autor: Lars-Owe Kjeller, Christoffer Rappe

Publikováno v: Toxicological & Environmental Chemistry. 67:481-490

Soxhlet extraction of polychlorinated dibenzo‐p‐dioxins/dibenzofurans (PCDD/F) from sediment was studied using a designed experimental set‐up. Three variables were studied: three solvent combinations n‐hexane/methanol, dichloromethane/acetone
