Abstract:

Objectives:
Cooking with gas or electric stoves produces fumes, especially during frying, that contain a range of harmful and potentially mutagenic compounds as well as high levels of fine and ultrafine particles. The aim of this study was to see if polycyclic aromatic hydrocarbons (PAHs) and higher mutagenic aldehydes which were collected in the breathing zone of the cook, could be detected in fumes from the frying of beefsteak.
Methods:
The frying was performed in a model kitchen in conditions similar to those in a Western European restaurant kitchen. The levels of PAHs (16 EPA standard) and higher aldehydes (trans,trans-2,4-decadienal, 2,4-decadienal, trans-trans-2,4-nonadienal, trans-2-decenal, cis-2-decenal, trans-2-undecenal, 2-undecenal) were measured during frying on an electric or gas stove with margarine or soya bean oil as the frying fat. The number concentration of particles <100 nm in size (ultrafine) was also measured, as well as the mass concentration of total particulate matter.
Results:
Levels of naphthalene were in the range of 0.15-0.27 microg/m(3) air. Measured levels of mutagenic aldehydes were between non-detectable and 61.80 microg/m(3) air. The exposure level of total aerosol was between 1.6 and 7.2 mg/m(3) air. Peak number concentrations of ultrafine particles were in the range of 6.0x10(4)-89.6x10(4) particles/cm(3) air.
Conclusion:
Naphthalene and mutagenic aldehydes were detected in most of the samples. The levels were variable, and seemed to be dependent on many factors involved in the frying process. However, according to the present results, frying on a gas stove instead of an electric stove causes increased occupational exposure to some of the components in cooking fumes which may cause adverse health effects.
