European biomonitoring initiatives have, across 28 European countries, produced data on population exposure to bisphenol A (BPA), one of the most widely discussed plastics-related chemicals. This work is part of a broad effort to map exposure to priority toxicants and to understand their possible health impacts. BPA remains a substance closely linked to many consumer plastics and packaging materials.
According to feedback from the NGO Hogar sin Toxicos, the initial results indicate that BPA was detected in all adult participants tested in Europe. They add that roughly half of those individuals also carried other bisphenols, such as bisphenol S and bisphenol F, which are increasingly used to replace BPA and may appear in high concentrations in some cases.
In total, 2,756 tests were conducted across 11 countries, representing a cross-section intended to reflect the broader population. Carlos de Prada, director of Hogar sin Toxicos, notes with concern that European biomonitoring data show levels exceeding what the European Food Safety Authority has previously deemed acceptable. After reviewing the evidence, he has urged authorities to reassess exposure standards and consider lowering safe intake estimates substantially.
Efforts to reduce exposure have not eliminated risk. Despite past recommendations, the European population has continued to face potential exposure to BPA through various channels, including food contact materials and packaging, with effects persisting even amid bans in some products.
Scientific findings link BPA exposure to neurodevelopmental concerns, altered birth weight, immune system development, fertility issues, obesity, and higher risks of metabolic disorders, hormone-related cancers, and cardiovascular disease. Biomonitoring data also show higher BPA concentrations compared with some replacement bisphenols, such as BPS and BPF, whose use has risen as substitutes. The rising presence of these compounds raises concerns about similar health risks, including exposure through everyday items like thermal paper receipts in cashiers’ work environments.
cocktail effect
Additionally, the biomonitoring initiative highlights the so-called cocktail effect: simultaneous exposure to multiple bisphenols appears to amplify potential adverse outcomes. Early findings suggest combined exposure to bisphenols and other chemicals in Western populations correlates with lowered semen quality, underscoring the need to consider cumulative impacts rather than a single chemical in isolation.
As summarized by experts, endocrine-disrupting pollutants can influence health even at very low concentrations, and there is no clearly established safe threshold for these substances. Ongoing discussions in European policy include pathways to restrict or ban various bisphenols in a coordinated manner as part of a broader strategy to limit toxic exposures.
Experts estimate the broader family consists of more than 200 related substances, with at least 37 suspected of hormone-modifying properties that may trigger effects at low levels. BPA remains the most well-known member, but evidence shows that several BPA substitutes can also pose health concerns.
In this context, researchers and regulators emphasize the importance of robust monitoring, precautionary measures, and proactive risk management to protect vulnerable populations, including pregnant individuals and young children, from potential exposure through everyday products.
Environment and health authorities continue to track biomonitoring results and explore risk reduction options that balance consumer needs with public health considerations. The field remains vigilant about cumulative exposure and the potential for long-term health implications across populations.
Notes and references for this overview are drawn from the HBM4EU program and related European framework documents, which document concerns about exposure levels and the need for ongoing policy action to reduce risks from bisphenols and similar endocrine-disrupting chemicals.
