Lake Geneva (G3). Results of All data concentration and IEL (integrated element load) trends before and after 2006 (Gd only after 2006). Values in bold are significant (p < 0.05). In IELs, slopes in italics are significant only when Hamed and Rao correction is not applied

^aAll calculated by MK, except Sr (SMK). 95% confidence intervals are for all Sen's slopes' values in MK calculations and for Sen's slopes' seasonal median values in SMK calculations; thus they are not directly comparable.

^bExcept for Sr, in μg L⁻¹ y⁻¹.

^cExcept for Sr, in mg y⁻¹.

^dHamed and Rao correction not needed because SMK includes serial correlation correction.

^eYearly increase = 100 × Sen's slope/median IEL (2006).
