Effect of temperature on the release of intentionally and non-intentionally added substances from polyethylene terephthalate (PET) bottles into water: Chemical analysis and potential toxicity

► Chemical analysis and toxicological assessments of PET-bottled water were carried out. ► High temperatures and carbonation increased migration from PET into water. ► Formaldehyde, acetaldehyde and Sb are the main compounds released from PET bottles. ► 2,4-dtBP and BHET, not listed in the EU Regulation, were detected in bottled water. ► Identified NIAS did not induce in vitro toxicological effects in PET-bottled water.
