• We model the blood concentrations of dioxins and PCBs on congener level.
• We use the models to predict the blood concentrations of dioxins and PCBs in an independent study population.
• We compared the predicted and the measured blood concentrations.
• The participants were to a great extent successfully placed in the right exposure category.

Dietary intake of polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs) by a population living in the vicinity of a hazardous waste incinerator. Assessment of the temporal trend

• Dietary exposure to PCDD/Fs in the vicinity of a HWI decreased considerable during the last 14years.
• Daily intakes of PCDD/Fs for different age/gender groups of the general population are notably lower than the TDI.
• Fish and seafood, oils and fats, and dairy products, are the food groups showing the highest contribution to total TEQ.

• Levels of DDTs and HCHs in food, dust and air samples from Shanghai, China
• Bioaccessibility of DDTs and HCHs in food was measured using an in vitro test.
• Daily uptake of DDTs and HCHs via ingestion, inhalation, and dermal contacts
• Ingestion via food and dust was the main route of human exposure to DDTs and HCHs.
• DDTs/HCHs from food consumption accounted for 95.0–99.2% of the total daily uptake.
