Sensitivity of Trout to Chronic Acute Exposure to Selenium

Gunnar Gissel Nielsen, M. Gissel Nielsen

    Research output: Contribution to journalJournal articleResearchpeer-review


    Trout were exposed to selenite (Na2SeO3) solutions of varying concentrations (0.1-100 ppm Se) for periods of up to 4 wk. A chronic exposure to 0.1 ppm Se or less is non-lethal to trout. Lethality at higher concentrations depends on the length of exposure. Trout that survive for 10 days in tap-water after contamination will not die as a result of Se toxicity and can safely be used for human consumption.
