Disentangling the effects of low pH and metal mixture toxicity on macroinvertebrate diversity: data sets This dataset is comprised of water quality data and benthic macroinvertebrate data collected from basins in Colorado, USA, and Finland. The data includes ancillary water quality characteristics but also a suite of trace metals observed at each site. Also included are modeled outputs that characterize the bioavailability of each trace metal to a biotic ligand. These data were used to explore the importance of metal toxicity and pH as stressors on benthic macroinvertebrates characterized as the number of unique Ephemeroptera + Plecoptera + Trichoptera genera observed at each site. An interpretive summary of the work follows. One of the primary goals of biological assessment of rivers is to identify whether contaminants...

Model results indicate that the carbonate content of soils and aquifer materials strongly controls pH and when coupled with long flow paths, results in the most alkaline conditions. Conversely, in areas where glacial sediments are thin and carbonate-poor, pH conditions remain acidic. At depths typical of drinking-water supplies, predicted pH > 7.5 – which is associated with arsenic mobilization – occurs more frequently...

Synopsis: This paper describes the spatial distribution of pH measurements from 60 sites distributed throughout the Kychlan River catchment, a 67km⊃2; boreal watershed in northern Sweden. Water samples were collected during a period of winter baseflow and during a spring flood episode. Chemical analyses included pH, Dissolved Organic Carbon (DOC), major cations (K, Mg, Na, Ca) and total filterable aluminum. Spring flood pH was shown to be highest in larger, lower altitude catchments underlain by fine sorted sediments, and lowest in small, higher altitude catchments underlain by a mixture of peat wetlands and forested till. There was also a trend with distance downstream of higher pH, acid neutralizing capacity and...
