Description
|
This document contains the principal component loadings of the BalatonUV–Eq emission model input parameters derived from a Principal Component Analysis (PCA) performed on 729 full-factorial parameter combinations (3⁶ design). The PCA was conducted on six z-score standardized variables representing behavioural and physicochemical drivers of sunscreen-derived organic UV-filter (OUVF) emissions into Lake Balaton: number of bathers (Φ), proportion of sunscreen users (Γ), treated skin surface area (Π), application frequency (Ω), total OUVF content (Δ), and wash-off factor (Ψ). The component loadings quantify the contribution of each standardized parameter to the first two principal components (PC1 and PC2), thereby enabling interpretation of dominant emission drivers and parameter co-variation structure within the model input space. This dataset supports transparent interpretation of the BalatonUV–Eq model structure and provides reproducible numerical evidence for the identification of key behavioural and formulation-related determinants of recreational OUVF emissions in freshwater systems. |
