Use of Human Biomonitoring in food risk assessment: assessing exposure to bisphenols in Portugal

Bisphenols are among the chemicals with the highest production volume worldwide and are used to make polycarbonate plastic containers for food use, such as beverage containers and plastic dinnerware, and in the internal coatings of food and beverage cans among other products. According to the scientific literature, small amounts of these compounds migrate from packaging into food resulting in human exposure. Although numerous studies have been carried out in order to assess its effects on human health, there are still uncertainties concerning the possible toxic effects of these compounds. Nevertheless, the most commonly used bisphenol, bisphenol A (BPA), is considered an endocrine disrupting compound. As a consequence, current European legislation prohibits the use of BPA in baby bottles, infant sipping cups and in the coating of food containers for children up to 3 years old and significantly tightens the restrictions on the use of BPA in other food contact materials. This has led to the replacement of BPA by other bisphenols, such as BPS and BPF, whose health effects are still largely unknown. Considering the above and that there is no data on the exposure of the Portuguese population to these compounds, a new project named INSEF-ExpoQuim is currently being developed by the National Health Institute Doutor Ricardo Jorge, in cooperation with the five Regional Health Administrations and the Regional Health Secretariats of the Autonomous Regions of the Azores and Madeira, as part of the European Human Biomonitoring Initiative HBM4EU with the aim to assess exposure to bisphenols in the Portuguese population and contribute to the food risk assessment of bisphenols in Portugal. It is expect that project results will contribute to the reduction of the impact on the health of the Portuguese population that could result from the exposure to these chemicals, by producing high quality data on the actual exposure of the population, in order to support the development and implementation of policy measures aimed at minimizing exposure.
