    Bisphenol A (BPA) is a plasticizer that interacts with the hormonal systems of the human body. In fact, its ability to behave like estrogens (female sex hormones) has been known since the 1930s, and its effects on fertility, reproduction, and the endocrine system have been the subject of significant scientific debate in recent years. BPA is found in water bottles, baby bottles, food containers, cans with coatings, and other plastic packaging, which has raised concern, since we currently live surrounded by plastic objects that contain this toxic agent, which generally causes harm to human health. Therefore, the objective of the present study was to determine the concentration of Bisphenol A in water contained in reusable water bottles (“tomatodos”) sold in the city of Lima, subjected to the temperatures and contact times to which they are exposed on a daily basis. A total of 24 samples were taken (12 blue bottles and 12 transparent bottles). The determination was carried out by high-performance liquid chromatography (HPLC), finding that all analyzed samples presented non-detectable concentrations of BPA, below the maximum levels established by the European Food Safety Authority (EFSA).
