(2020). The concentration data represent the triplicate median value and comes from grab samples that were preserved in the field before analyzed at laboratories at the Department of Environmental Science and at the Department of Geological Sciences at Stockholm University through ion chromatography (Thermo Scientific Dionex), total organic carbon analyzer (Shimadzu TOC-V CPH), and inductive couple plasma optical emission spectrometry (ICP-OES; Thermo Scientific iCAP 6000 Series). Sampling and analysis followed the methodologies in Fischer et al. (2020). Sulfur isotopic data was analyzed at laboratories at the Department of Geological Sciences at Stockholm University through an elemental analyzer (CarloErba NC2500) coupled to a stable isotope ratio mass spectrometer (Finnigan Thermo Delta plus) according to the methods in Fischer et al. (2022; Environmental Pollution). Sampling locations were chosen in relation to the potential pollution sources from the active apatite mining industry, i.e.: - Upstream: sampling locations assumed undisturbed by direct mining activities - Mine: sampling locations within or directly downstream mining activity - Downstream: sampling locations further downstream of mining activity
