Description
|
This figure presents a detailed spatiotemporal heatmap illustrating concentrations of five organic UV-filters (AVO, OC, EHMC, DBT, EHT) measured in surface waters of Lake Balaton (Hungary).
The heatmap displays concentration values (ng/L) across 17 shoreline sampling sites and five discrete sampling campaigns, enabling simultaneous visualization of spatial distribution patterns and seasonal variability. Color gradients represent concentration intensity, facilitating identification of contamination hotspots and peak tourism-related exposure periods.
The dataset underlying this visualization originates from a matrix-optimized SPE–UHPLC–MS/MS analytical method applied to multi-season monitoring campaigns.
This figure supports interpretation of recreationally driven contamination dynamics in a large shallow freshwater ecosystem and highlights the pronounced in-season concentration increases associated with intensive sunscreen usage. |
