Description
|
This dataset contains calculated sediment–water distribution coefficients (Kd) for five organic UV filters (avobenzone, octocrylene, octinoxate, iscotrizinol, and ethylhexyl triazone) in Lake Balaton (Hungary).
Kd values (L/kg dry weight) were calculated as the ratio of mean compound concentrations measured in surface sediment (ng/g d.w.) to corresponding mean concentrations in surface water (ng/L), separately for recreational in-season and out-of-season periods. The calculation method was applied consistently across all compound–matrix combinations.
The dataset provides quantitative insight into sediment-associated retention and partitioning behaviour of sunscreen-derived organic UV-filters in a shallow freshwater lake system. These coefficients support evaluation of environmental fate, persistence, and benthic compartment accumulation under seasonal recreational pressure. |
