. A lot of has been heard about dioxins and dioxins-like compounds. These molecules are typically connected in public awareness with affairs. The main source of dioxins for humans is food (90% of typical exposition); thus, assessment of dioxins intake and monitoring of levels of dioxins in food remain an important issue. Objective. The aim of the presented work was checking the reproducibility of the authors’ semi-quantitative food frequency questionnaire, focusing on products that may contain dioxins and related compounds among adolescents. The uptake of these compounds was also assessed using obtained data. For survey purposes, an album of food products from the questionnaire was constructed.
Materials and method. A modified semi-quantitative food frequency questionnaire was constructed and distributed twice in a 2-week time span among 55, 15-year-old, students of secondary schools.
Results. The correlation coefficient for both declared frequencies and assessed amounts in the case of the majority of food items was above 0.70. The average assessed intake of dioxins and related compounds was 1.57pgWHO-TEQ/kg body weight per day, and 1.85 pgWHO-TEQ/kg body weight per day, during test and retest, respectively.
Conclusions. The modified semi-quantitative food frequency questionnaire is a reproducible tool that can be used for adolescents. Average intake in the analyzed group was lower than the Tolerable Daily Intake, but in contrast to other countries remains one of the highest intakes in a comparable age group. The main sources of dioxins exposition were fish (38%), and meat product
