Exposure apportionment: Ranking food items by their contribution to dietary exposure

Dietary Exposure Assessment of Chemicals in Food

Contribution of PCB exposure from fish consumption to total dioxin-like dietary exposure.

Polychlorinated biphenyls (PCB) are the second greatest cause of fish advisories, and are often the greatest contributors to dioxin-like toxic equivalency (TEQ) in fish and seafood. Because fish consumption is associated with both contaminant risks and health benefits, incremental health risks from PCBs in fish should be considered within the context of overall TEQ associated dietary risk to en...

Contribution of street food on dietary acrylamide exposure by youth aged nineteen to thirty in Perugia, Italy

Acrylamide dietary intakes from selected street foods in youth population are estimated. The intake evaluation was carried out by combining levels of acrylamide in food, analytically determined by high performance liquid chromatography, with individual consumption data recorded using a questionnaire applied to a group of 200 students aged 19 to 30. The mean value of acrylamide exposure was reco...

Phthalates in Fast Food: A Potential Dietary Source of Exposure

The authors used data from the National Health and Nutrition Examination Survey (NHANES) to estimate the percentage of individuals’ calories that came from fast food, fat intake attributable to fast food consumption, and fast food intake by food group. During NHANES interviews, respondents had reported their diet from the preceding 24 hours. Fast food was defined as food obtained from restauran...

Source apportionment of exposure to toxic volatile organic compounds using positive matrix factorizationSource apportionment of exposure to toxic volatile organic compounds using positive matrix factorization

Data from the Total Exposure Assessment Methodology studies, conducted from 1980 to 1987 in New Jersey (NJ ) and California (CA) , and the 1990 California Indoor Exposure study were analyzed using positive matrix factorization, a receptor -oriented source apportionment model. Personal exposure and outdoor concentrations of 14 and 17 toxic volatile organic compounds (VOCs) were studied from the ...
