Fish - a source of dietary exposure to iodine and other chemicals.

Fish, fish products and seafood are an important part of a healthy diet. They make an important contribution as a dietary source of iodine, but also of other substances that have a positive effect on the human body. On the other hand, they contain contaminants (especially mercury/methylmercury) whose toxic properties affect food safety.

Cumulative dietary risk assessment overarching different regulatory silos using a margin of exposure approach: A case study with three chemical silos.

Risk assessment of chemicals occurring in our diet is commonly performed for single chemicals without considering exposure to other chemicals. We performed a case study on risk assessment of combined dietary exposure to chemicals from different regulatory silos, i.e.

Dietary exposure assessment of sum deoxynivalenol forms, sum T-2/HT-2 toxins and zearalenone from cereal-based foods and beer.

A dietary exposure assessment to sum of deoxynivalenol (DON) forms, sum of T-2/HT-2 toxins (T2/HT2) and zearalenone (ZEA) was conducted for Czech children 4-6 years and Czech men and women 18-59 years. Retail foods (25 different commodities, n = 336) were assessed by LC-MS/MS methods. The 95th percentile chronic exposure to sum of DON forms was determined in children from 648 to 1030 ng/kg bw/day (LB/lower bound/and UB/upper bound/), in men from 362 to 923 ng/kg bw/day and in women from 272 to 490 ng/kg bw/day.

Selecting mixtures on the basis of dietary exposure and hazard data: application to pesticide exposure in the European population in relation to steatosis.

Populations are exposed to mixtures of pesticides through their diet on a daily basis. The question of which substances should be assessed together remains a major challenge due to the complexity of the mixtures. In addition, the associated risk is difficult to characterise.

Dietary Intake of Vitamin D in the Czech Population: A Comparison with Dietary Reference Values, Main Food Sources Identified by a Total Diet Study.

The usual dietary intake of vitamin D was studied in 10 subgroups of the Czech population. Food consumption data was collected using repeated 24 h recall in a national cross-sectional survey (the Study of Individual Food Consumption, SISP04), and the vitamin D content in marketed foods was quantified within the national Total Diet Study (2014⁻2015). The Monte Carlo Risk Assessment computational model (version MCRA 8.
