This dataset contains multi-matrix concentration data of five organic UV-filter compounds (avobenzone, octocrylene, octinoxate, iscotrizinol, and ethylhexyl triazone) collected from Lake Balaton (Hungary) between 2022 and 2024. Samples were obtained from 17 shoreline locations and include surface water, sediment (dry weight), periphyton, and zebra mussel (Dreissena polymorpha) tissue. Concentrations were determined using a matrix-optimized SPE–UHPLC–MS/MS analytical method. The dataset further includes calculated sediment–water distribution coefficients (Kd), bioaccumulation factors (BAF), acute risk quotient (RQ) values, mixture toxicity indices (TU_mix), and model outputs from a multiparametric recreational emission model (BalatonUV–Eq) estimating seasonal OUVF inputs during the bathing period. The data support spatio-temporal analysis of recreational contaminant inputs and screening-level environmental risk assessment in shallow freshwater systems. Hungary
