Parabens are recognized as emerging contaminants. Used in the pharmaceutical and cosmetic industries, they present significant ecological risks to aquatic ecosystems. This study evaluated effects of two parabens—methyl 4-hydroxybenzoate (methylparaben) propyl (propylparaben)—both individually a mixture on daphnids. Through series controlled exposure experiments, phenotypic endpoints, including mortality, feeding behaviour, enzymatic activity, were measured. The results demonstrate that paraben methyl exhibit greater toxic potential compared alone. We observed dose-dependent impact key enzymes, indicating metabolic disruption. These findings underscore necessity utilizing model systems investigate complex interactions cumulative impacts pollutant mixtures environments. Furthermore, this provides critical insights regarding underlying toxicity mechanisms parabens, highlighting need for comprehensive water quality monitoring risk assessment frameworks address challenges posed by
