Zusammenfassung englisch
In the study presented here, we evaluated the exposure of the German population aged 14-80 years tobis(2-ethylhexyl)phthalate (DEHP) from consumption of food by means of deterministic and probabilisticestimations. The study was performed on the basis of an extensive review of literature from around theworld reporting measured data on DEHP in food, as well as official German food control data. Only datafrom individual measurements were considered and used for fitting of distributions. A wide range ofconcentrations in non-representative samples are reported in the literature. On the basis of the availableDEHP concentration data, 37 food categories were characterized which covered all major food classes.Food consumption data were taken from the diet history interviews of the German National NutritionSurvey II (Nationale Verzehrsstudie II) which was performed in 2005/2006 in a representative studypopulation of 15,371 and is the most recent data source of this kind in Germany. Average DEHP intakewas estimated deterministically using data on measured concentrations in food (medians and means)and food consumption (means). A total dietary exposure to DEHP of 3.6 (median based) and 9.3 g/kg ofBW per day (based on mean values) was estimated deterministically. In addition, distributions of bothconcentrations and consumption figures were fitted using the @RISK best fit tool for further probabilisticestimations. This approach resulted in estimates within the same range: the estimated median DEHPintake in the whole population (both non-consumers and consumers of the foods considered) was 10.2,the arithmetic mean 14.0 and the 95th percentile 28.6 g/kg of BW per day. The respective estimatesfor consumers only were 12.4, 18.7 and 36.5 g/kg of BW per day. These results demonstrate that theprobabilistic approach is able to estimate broader ranges of exposure even when using data representingan average intake. Moreover, it reflects the uncertainties of the estimation due to insufficient analyticaldata on concentrations of DEHP in food.
