Abstract:Selenium (Se) bioaccumulation and toxicity in aquatic vertebrates have been thoroughly investigated over the past two decades. Limited information is available on Se bioaccumulation at the base of aquatic food webs. In this study, we selected two laboratory-reared benthic macroinvertebrates (BMI), Hyalella azteca and Chironomus dilutus, to investigate Se bioaccumulation potential in a Canadian boreal lake (McClean Lake) receiving continuous Se input from a Saskatchewan uranium mill. Laboratory and in-situ expe… Show more
