We investigated the associations between exposure to bisphenols and biomarkers of oxidative stress in human studies over the last 12 years (2008-2019) related to six health endpoints and evaluated their suitability as effect biomarkers. PubMed database searches identified 27 relevant articles that were used for data extraction. In all studies, BPA exposure was reported, whereas some studies also reported other bisphenols. More than a dozen different biomarkers were measured. The most frequently measured biomarkers were 8-oxo-7,8-dihydro-20 -deoxyguanosine (8-OHdG), 8-iso-prostaglandin F2α (8-isoprostane) and malondialdehyde (MDA), which almost always were positively associated with BPA. Methodological issues were reported for MDA, mainly the need to handle samples with caution to avoid artefact formation and its measurements using a chromatographic step to distinguish it from similar aldehydes, making some of the MDA results less reliable. Urinary 8-OHdG and 8-isoprostane can be considered the most reliable biomarkers of oxidative stress associated with BPA exposure. Although none of the biomarkers are considered BPAor organ-specific, the biomarkers can be assessed repeatedly and non-invasively in urine and could help to understand causal relationships.}, organization = {HBM4EU project - European Union's Horizon 2020 research and innovation program 733032}, publisher = {MDPI}, keywords = {Adverse outcome pathway (AOP)}, keywords = {Analytic methods}, keywords = {Antioxidant}, keywords = {Bisphenol F (BPF)}, keywords = {Bisphenol S (BPS)}, keywords = {Effect biomarker}, keywords = {HBM4EU}, keywords = {4-hydroxy-2-nonenal-mercapturic acid (HNE-MA)}, keywords = {Reactive nitrogen species (RNS)}, keywords = {Reactive oxygen species (ROS)}, title = {Bisphenols and Oxidative Stress Biomarkers—Associations Found in Human Studies, Evaluation of Methods Used, and Strengths and Weaknesses of the Biomarkers}, doi = {10.3390/ijerph17103609}, author = {Steffensen, Inger Lise and Fernández Cabrera, Mariana Fátima and Mustieles Miralles, Vicente and Rodríguez Carrillo, Andrea}, }
