Polychlorinated Biphenyls: Gas Chromatography
نویسنده
چکیده
nical mixtures found in the formulation and the measurements made on the basis of calibration with these mixtures. Chlorobiphenyl (CB) refers to the individual congener named by the Ballschmiter number. TEQs refer to the sum of the concentration of the congener equivalent to 2, 3, 7, 8 TCDD obtained by using the toxic equivalence factor for each PCB. POLYCHLORINATED BIPHENYLS: GAS CHROMATOGRAPHY

Estimation of Polychlorinated Biphenyls Intake through Fish Oil-Derived Dietary Supplements and Prescription Drugs in the Japanese Population
Background: Oily fish and their extracted oils may be a source of polychlorinated biphenyls (PCBs) which can induce toxic effects on the consumers. The main aim of this survey was estimation of PCBs intake through fish oil-derived dietary supplements and prescription drugs in the Japanese population. Methods: PCBs levels were determined in 20 fish oil-derived dietary supplements and 6 oil-deri...
متن کاملDetermination of vaporization enthalpies of polychlorinated biphenyls by correlation gas chromatography.
The vaporization enthalpies of 16 polychlorinated biphenyls have been determined by correlation gas chromatography. This study was prompted by the realization that the vaporization enthalpy of the standard compounds used in previous studies, octadecane and eicosane, were values measured at 340 and 362 K, respectively, rather than at 298 K. Adjustment to 298 K amounts to a 7-8 kJ/mol increment i...
متن کاملMethod development for the analysis of polybrominated diphenyl ethers, polychlorinated biphenyls, polychlorinated dibenzo-p-dioxins and dibenzo-furans in single extract of sediment samples.
A comprehensive method was developed for quantitative analysis of polybrominated diphenyl ethers (PBDEs), polychlorinated biphenyls (PCBs) and polychlorinated dibenzo-p-dioxins and dibenzo-furans (PCDD/Fs) in one single extract of environmental samples. The sample preparation procedure included two fractionation steps using silver nitrate silica chromatography to separate PBDEs from PCBs and PC...
متن کاملSource Identification and Health Risk Assessment of Polychlorinated Biphenyls (PCBs) in Surface Soils from Vicinity of Arad-Kouh Processing and Disposal Complex, Tehran
Polychlorinated biphenyls (PCBs) can adversely affect human and environmental health according to long-term half-life and persistence in the environment. Therefore, this study was conducted to detect, identify, and health risk assessment of PCBs in surface soils collected from the vicinity of Arad-Kouh processing and disposal complex, Tehran, in 2020. A total of 30 surface soil samples was coll...
متن کاملPossibilities and limitations of capillary gas chromatography and mass spectrometry in the analysis of polychlorinated biphenyls.
The possibilities and limitations of analyses of polychlorinated biphenyls (PCBPs) by capillary gas chromatography and capillary gas chromatography-mass spectrometry have been investigated. Metal capillary columns (WCOT) coated with Apiezon L and OV-101 were not suitable for PCB analyses. Good results were obtained in the separation of model mixtures of PCBs and of Aroclor 1242 on a glass capil...
