Abstract
High resolution gas chromatography, with mass selective detection, has been used for the analysis of PCB on methyl 50 % octyl polysiloxane (SB 50 Octyl), methyl octadecyl polysiloxane, and a smectic polysiloxane (SB Smectic); and for the analysis of polychlorodibenzodioxins and polychlorodibenzofurans with 1 to 8 chlorine substituents on 100 % cyanopropyl siloxane (SP 2331), smectic polysiloxane (SB Smectic), a new polar stationary phase (DBβDioxin). The analysis has also been performed by column coupling.

The effects of the introduction of chlorine substituents onto phenol on the rates of, and products from, their slow combustion at 500-550 Β°C are described. Competitive experiments showed that phenol, ortho-chlorophenol, 2,4,6-trichlorophenol and pentachlorophenol differ little in their overall rates
Although chlorinated paraffins (CP) are produced in large amounts (300000 tonnes per year), little is known about their occurrence in the environment due to the lack of specific and sensitive analytical methods. The present paper describes the GC/MS analysis of different CP's using capillary gas chr
The aerobic dechlorination of 4chlorobiphenyl and of Aroclor 1221 by Pseudomonas sp. CPEl strain was enhanced by the presence of hydroxypropyl-p-cyclodextrin in the medium. The best dechlorination results were obtained when 4-chlorobiphenyl or Aroclor 1221 and the cyclodextrin were used at the molar
