[Study on the chemical components of edible oil fume in kitchen and its genotoxity on Drosophila].
OBJECTIVE
To study the chemical components of the condensate of edible oil fume in kitchen and its genotoxicity on Drosophila.


METHODS
Analysis for the chemical components was carried out by gas chromatography and mass spectra (GC/MS) and its genotoxicity was studied by sex linked recessive lethal (SLRL) test in Drosophila.


RESULTS
A total of 74 organic compounds were found in samples of condensed oil from the fume in kitchen. It included hydroxylic acids, hydrocarbons, alcohols, esters, aldehydes, ketones, aromatic compounds, and steroids, etc. The total mutagenicity rates in SLRL test induced by the samples at concentrations of 110,320 and 960 mg/L were 0.1732%, 0.4306% and 0.1707% respectively. The sterility rates of the first broods were 2.564%, 2.056% and 2.845% at above 3 concentrations respectively(P < 0.05, as compared with the control). The mutagenicity rate of the second brood at 320 mg/L was 0.530% and that of the third brood at 110 mg/L 0.540%(P < 0.001).


CONCLUSIONS
Some of the compounds in the condensate of edible oil fume were proved to have high recessive lethal effect and genotoxic effect on the reproductive system of Drosophila.
