Chronic Radium-226 toxicity to and oxidative stress in the aquatic invertebrate <i>Chironomus dilutus</i>.

ABSTRACT: The mining industry, including uranium mining and milling, is of high importance in Canada. It is, however, important to consider that ore processing can result in the creation of by-products that contain radionuclides such as radium-226 (²²⁶Ra). Even with the strict discharge regulations in place, there is limited evidence to suggest that the current Canadian regulatory thresholds for ²²⁶Ra are protective for aquatic life. This concern underscores the importance of generating toxicity data for ²²⁶Ra, as no federal Canadian water quality guidelines for ²²⁶Ra currently exist to safeguard aquatic ecosystems. The potential ecological risks of ²²⁶Ra are significant due to its high mobility under typical environmental conditions, long half-
