摘要:Benzo [α] pyrene which is known to be an environmental carcinogen was analyzed by a duplicate portion study in order to calculate daily dietary intake. In the first study food samples were prepared by six housewives for one week and in the second study the samples were prepared by twenty five housewives for one day twice in summer and once in fall. The results of analyses of 117 samples showed that the average intake level was 39 ng/d and the distribution of intake showed a log-normal distribution pattern. Benzo [α]-pyrene intake levels were significantly correlated with the amount of meat and fish eaten after the cooking process, although there was no significant correlation between its intake and the amount of raw meat or fish in a recipe. This suggested that the level of benzo [α] pyrene consumed in food was largely formed during the cooking process.
