500 |a"The objective of this project was to obtain samples of selected aquatic biota (i.e., invertebrates, "biofilm", and forage fish) from nine sites in the Athabasca River for contaminants analyses and quantitative analyses of invertebrate and biofilm abundance and biomass. Samples for contaminant analyses were destined for organic contaminant (e.g., dioxins, furans, chlorophenols, and polyaromatic hydrocarbons), metal (e.g., arsenic, vanadium, copper, chromium lead, zinc, and methyl mercury) and stable isotope (e.g., carbon, nitrogen, sulphur analyses). Quantitative samples of aquatic invertebrates were required for estimates of abundance and biomass. Quantitative biofilm samples were collected for chlorophyll A and loss on ignition; samples were also retained for taxonomic identification."--Executive summary.
