How much BPA do we eat and drink?

Bisphenol A (BPA) is used as an intermediate in the production of polycarbonate plastics and epoxy resins. Although BPA is considered a ubiquitous environmental pollutant, BPA has raised concern regarding adverse human health effects. The aim of this article was to investigate human BPA exposure through food and beverages. A literature search was conducted combining the keyword BPA with keywords food, water, air, soil, health in PubMed, Science Direct, Web of Science, Scopus, and Google Scholar databases, covering both the area of environmental pollutants and influence on health. Food for human consumption is contaminated both during growth and cultivation, through contaminated soil and water as well as processing and packaging due to the materials containing BPA. Most of BPA migrates from packaging into liquid or solid phase showing that migration from PET bottles ranges from 2.89 to 38.9 ng/L, from PVC pipes between 0.01 and 28.83 ng/L, and from can coating between 21.86 and 1858.71 µg/kg. Concentrations of BPA in fruit and vegetables range from 18.3 to 128.9 µg/kg, in honey from <LOQ to 107 ng/g, in meat from not detected (in raw meat) to 21.3 ng/g (for canned meat), in milk from 33.8 to 127.2 µg/kg and in infant formulas between 0.003 and 0.375 µg/g. Current EFSA and EU legislative recommends a tolerable daily intake of 0.004 mg/kg body weight/day and migration limit for food contact materials of 0.4 mg/L. Researchers’ awareness of the harmful effects of BPA has led to the production of alternative materials as well as to the gradual reduction and elimination of the use of BPA-containing materials.
