Summary

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 or other stressors [...]

Purpose

The data were collected to assess the effect of different land use disturbances on water quality and aquatic life. In Colorado, USA, the effect of natural geologic processes was considered as a major determinant of metal bioavailability to aquatic life that is important to consider when assessing risks to aquatic ecosystems associated with mining of different types of mineral deposits. In Finland, similar data were collected at sites that were influenced by different forestry practices. Collectively, the data present characteristics of aquatic ecosystems that are naturally acidic and systems that become acidic once disturbed by different land uses. Here the data were used collectively to differentiate the unique effects of low pH from that of metals on benthic macroinvertebrate communities.
