A survey of baseline levels of contaminants in aquatic biota of the AOSERP study area
Analyses are given for up to 12 metals and 4 pesticides with PCBs, of aquatic environment from 15 study sites along or near the Athabasca River from Fort McMurray north to the confluence of the Peace and Slave Rivers. There were 560 fish (8 species), 15 water, 14 sediment and a few phyto-plankton an...

Analyses are given for up to 12 metals and 4 pesticides with PCBs, of aquatic environment from 15 study sites along or near the Athabasca River from Fort McMurray north to the confluence of the Peace and Slave Rivers. There were 560 fish (8 species), 15 water, 14 sediment and a few phyto-plankton and invertebrate samples. Methods of analysis (by AAS and GLC) are outlined, and standard deviations and detection limits given. In a few cases, where suspected, elevated concentrations of metals and pesticides are discussed.
