چکیده انگلیسی
A gas chromatography-mass spectroscopic method in electron ionization (EI) mode with MS/MS ion preparation using helium at flow rate 1 ml minâ1 as carrier gas on DB-5 capillary column (30 m Ã 0.25 mm i.d. film thickness 0.25 μm) has been developed for the determination of benzene in indoor air. The detection limit for benzene was 0.002 μg mlâ1 with S/N: 4 (S: 66, N: 14). The benzene concentration for cooks during cooking time in indoor kitchen using dung fuel was 114.1 μg mâ3 while it was 6.6 μg mâ3 for open type kitchen. The benzene concentration was significantly higher (p < 0.01) in indoor kitchen with respect to open type kitchen using dung fuels. The wood fuel produces 36.5 μg mâ3 of benzene in indoor kitchen. The concentration of benzene in indoor kitchen using wood fuel was significantly (p < 0.01) lower in comparison to dung fuel. This method may be helpful for environmental analytical chemist dealing with GC-MS in confirmation and quantification of benzene in environmental samples with health risk exposure assessment.
