The increasing demand for personal care products (PCPs)—which contain preservatives,antimicrobials, and fragrances used in cosmetic and hygiene formulations—has contributed tothe release of emerging contaminants into the environment. These substances currently lackspecific regulations for control and monitoring. Furthermore, limited or absent wastewatertreatment enables their discharge into aquatic ecosystems, where they can bioaccumulate, disruptendocrine function, and negatively impact aquatic organisms. This study aimed to determine thebioconcentration factor (BCF) of four commonly used parabens in Latin America —methylparaben (MeP), ethylparaben (EtP), propylparaben (PrP), and butylparaben (BuP)— inzebrafish as an experimental model. A 96-hour exposure was conducted using a constantconcentration of 1 mg/L of each compound, with daily water renewal. At the end of the exposureperiod, whole-fish homogenates were extracted using the QuEChERS method and analyzed byHPLC-MS/MS (Waters Alliance – Quattro Premier XE). The BCF results followed the trend:BuP = PrP > EtP > MeP, with no statistically significant difference between PrP and BuP, whichshowed the highest levels of bioconcentration. These results align with the expected trend, asbioconcentration typically increases with linear alkyl chain length. In conclusion, these emergingcontaminants are entering the environment and accumulating in aquatic organisms, potentiallycausing adverse effects on ecosystems. These findings underscore the urgent need for regulatorymeasures and improved wastewater treatment practices to mitigate the ecological risks posed bythe accumulation of paraben-based contaminants in aquatic ecosystems.
