Abstract

In the context of this research, several physical, chemical, and ecotoxicological parameters are determined in bottom sediments from reservoirs and lakes along the (South) Saskatchewan River in Saskatchewan. These data are collected to support the comprehensive ecotoxicological characterization of these sediments, with the ultimate goal of weighing different options for sediment restoration in the Saskatchewan River Delta. The investigated lakes and reservoirs include Lake Diefenbaker, Codette Reservoir, Tobin Lake, and Cumberland Lake. The measured parameters include sediment texture and total organic carbon, concentrations of common contaminants (metals, polycyclic aromatic hydrocarbons, polychlorinated biphenyls, polychlorinated dibenzo-p-dioxins and -furans, pesticides), as well as ecotoxicological parameters (cytotoxicity, dioxin-like activity, mutagenicity, (anti-)estrogenicity, (anti-)androgenicity).

Purpose

These data are collected to support the comprehensive ecotoxicological characterization of bottom sediments from reservoirs along the (South) Saskatchewan River in Saskatchewan. Ultimately, this characterization will help inform the range of potential interventions to help and restore sediment quality and quantity in the Saskatchewan River Delta.
