Abstract

The study presented here aims to permit further refinements in exposure assessments for migrants from food-contact materials by contributing to the characterization, at the household level, of the food packaging usage (amount and type) of Portuguese urban families. Packages from domestic use were collected from a sample of 105 consumers from 34 households over a 30 day period. Collected packages (more than 6 000 items) were characterized in the laboratory and data were used to estimate: (i) global packaging usage and food intake; (ii) the consumption factors (CF) that describe the fraction of the daily diet expected to contact specific packaging materials and (iii) the food-type factors (FTF) that reflect the fraction of all food contacting each material that is different in nature according to 6 major types: aqueous, acidic, alcoholic, milky, fatty and dry. The daily intake of packaged food and beverages consumed at home ranged from 5 to 50 g/kgbw. Considering all materials, total package usage ranged from 0.1 to 0.6 dm2/day.kgbw. The ratio between package surface area in contact and the quantity of food was determined for all packaging items collected and an average value of 25 dm2/kgfood was recorded. Data were gathered and presented in a manner compatible with current probabilistic approaches to exposure assessment. In this way, relevant consumption patterns from this type of population can be best represented in exposure assessments and consequent risk assessments.
