SummaryThe release of bisphenol A (BPA) from polyethylene terephthalate (PET) bottles in non‐carbonated water was investigated in this work through migration and leaching tests. Several types of PET bottles approved and used by several Romanian non‐carbonated mineral water brands were tested in this work. It was highlighted that both the storage temperature and the storage time of bottled water in PET bottles influence the degree of PBA release. Thus, increasing the temperature and storage time favours the release of BPA from PET. The higher the storage temperature, the higher is the diffusivity of BPA. The degree of BPA release is also closely related to the brand of PET. This could be related to the degree of contamination of the raw material in the manufacturing process of PET bottles or during their recycling. The physico‐chemical characteristics and stability of PET bottles in different environmental conditions can also influence the release of BPA from them. The leaching tests confirmed the potential for BPA contamination of long‐term non‐carbonated water bottled in PET bottles.
