Description
|
This dataset contains site- and date-specific mixture toxicity indices (TU_mix) calculated for five organic UV-filters (AVO, OC, EHMC, DBT, EHT) measured in surface waters of Lake Balaton (Hungary).
TU_mix values were calculated using the concentration addition (CA) model, where individual toxic units (TU_i = MEC_i / EC₅₀_i) were summed across compounds for each sampling site and date. Measured environmental concentrations (MEC, ng/L) were derived from field monitoring campaigns, and acute EC₅₀ values for freshwater organisms were used as toxicity endpoints.
Results are provided for both recreational in-season and out-of-season sampling campaigns, allowing assessment of spatial variability and seasonal mixture toxicity dynamics in a large shallow freshwater recreational ecosystem.
TU_mix values represent screening-level acute mixture toxicity indicators and are intended to support relative comparison of cumulative UV-filter exposure rather than comprehensive chronic ecological risk assessment.
This dataset provides rare field-based mixture toxicity evaluation data for organic UV-filters in freshwater surface waters. |
