Heavy metals in bottom sediments of the mainstem Athabasca river system in the AOSERP study area
Dredged sediments and sediment cores were collected from sites along the Athabasca River system from between Fort McMurray and the confluence of Riviere des Rochers with the Slave River. A selected sample suite representing all of the drainage units and textural variations was analysed by several to...
