“…Few studies of legacy and novel organic contaminants in freshwater bodies of the Arctic region have been conducted, providing limited possibilities for comparisons with our results ( Table 1). The apparent water concentration of P 7 PCBs in streams of V€ asterbotten County, northern Sweden, varied greatly with season and ranged from 3.9 to 79 pg/L (Bergknut et al 2011;Josefsson et al 2011Josefsson et al , 2016. The mean P 10 PCBs in filtered water samples from the mouths of the Yenisei and Ob Rivers (Russia) flowing into the Arctic Ocean were 17 AE 6.1 and 9.9 AE 3.8 pg/L in 2003 to 2005 (Carroll et al 2008).…”

“…Like the PCBs, the lower-molecular weight congeners of the PBDEs dominated water samples as measured with the PE passive samplers. Congeners BDE28 and 47 accounted for between 45 and 80% Josefsson et al (2011Josefsson et al ( , 2016; study area: Krycklan catchment area, Sweden). of the congeners measured by the PE passive samplers compared to <10% in the grab samples (Supplemental Data, Figure S4).…”

“…Early studies documented deposition of polychlorinated biphenyls (PCBs) and DDT compounds in Sweden (Larsson and Okla 1989;Agrell et al 2002) and found that levels in terrestrial biota were correlated with deposition fluxes (Larsson et al 1990). We do know that concentrations of PCBs and dioxins and furans (PCDD/Fs) can be surprisingly elevated in boreal forest streams of northern Sweden (Bergknut et al 2011;Josefsson et al 2011Josefsson et al , 2016. Routine atmospheric monitoring of POPs is now conducted in Arctic regions of Finland (Anttila et al 2016) and Norway (Bohlin-Nizzetto and Aas 2016).…”

“…By contrast, fewer data are available concerning the occurrence and levels of persistent chemicals in aquatic environments of Arctic and subarctic northern Sweden. We do know that concentrations of PCBs and dioxins and furans (PCDD/Fs) can be surprisingly elevated in boreal forest streams of northern Sweden (Bergknut et al 2011;Josefsson et al 2011Josefsson et al , 2016.

We report concentrations of polychlorinated biphenyls, polybrominated diphenyl ethers, novel flame retardants, and naturally occurring bromoanisoles in water and filter-feeding black fly (Simuliidae) larvae in 3 tundra streams in northern Sweden. The results demonstrate that black fly larvae accumulate a wide range of organic contaminants and can be used as bioindicators of water pollution in Arctic streams.

Improving our ability to detect changes in terrestrial and aquatic systems is a grand challenge in the environmental sciences. In a world experiencing increasingly rapid rates of climate change and ecosystem transformation, our ability to understand and predict how, when, where, and why changes occur is essential for adapting and mitigating human behaviours. In this context, long-term field research infrastructures have a fundamentally important role to play. For northern boreal landscapes, the Krycklan Catchment Study (KCS) has supported monitoring and research aimed at revealing these changes since it was initiated in 1980. Early studies focused on forest regeneration and microclimatic conditions, nutrient balances and forest hydrology, which included monitoring climate variables, water balance components, and stream water chemistry. The research infrastructure has expanded over the years to encompass a 6790 ha catchment, which currently includes 11 gauged streams, ca. 1000 soil lysimeters, 150 groundwater wells, >500 permanent forest inventory plots, and a 150 m tall tower (a combined ecosystem-atmosphere station of the ICOS, Integrated Carbon Observation System) for measurements of atmospheric gas concentrations and biosphere-atmosphere exchanges of carbon, water, and energy. In addition, the KCS has also been the focus of numerous high resolution multi-spectral LiDAR measurements and large scale experiments. This large collection of equipment and data generation supports a range of disciplinary studies, but more importantly fosters multi-, trans-, and interdisciplinary research opportunities. The KCS attracts a broad collection of scientists, including biogeochemists, ecologists, foresters, geologists, hydrologists, limnologists, soil scientists, and social scientists, all of whom bring their knowledge and experience to the site. The combination of long-term monitoring, shorter-term research projects, and large-scale experiments, including manipulations

Catchment science plays a critical role in the protection of water resources in the face of ongoing changes in climate, long‐range transport of air pollutants, and land use. Addressing these challenges, however, requires improved understanding of how, when, and where changes in water quantity and quality occur within river networks. To reach these goals, we must recognize how different catchment features are organized to regulate surface chemistry at multiple scales, from processes controlling headwaters, to the downstream mixing of water from multiple landscape sources and deep aquifers. Here we synthesize 30‐years of hydrological and biogeochemical research from the Krycklan catchment study (KCS) in northern Sweden to demonstrate the benefits of coupling long‐term monitoring with multi‐scale research to advance our understanding of catchment functioning across space and time. We show that the regulation of hydrological and biogeochemical patterns in the KCS can be decomposed into four, hierarchically structured landscape features that include: (1) transmissivity and reactivity of dominant source layers within riparian soils, (2) spatial arrangement of groundwater input zones that govern water and solute fluxes at reach‐ to segment‐scales, (3) landscape scale heterogeneity (forests, mires, and lakes) that generates unique biogeochemical signals downstream, and (4) broad‐scale mixing of surface streams with deep groundwater contributions. While this set of features are perhaps specific to the study region, analogous hierarchical controls are likely to be widespread. Resolving these scale dependent processes is important for predicting how, when, and where different environmental changes may influence patterns of surface water chemistry within river networks.
