The strategies determine bioaccumulation potential using one or more of three measures: the bioaccumulation factor (BAF), the bioconcentration factor (BCF), and the log of the octanol-water partition (log Kow).
where [C.sub.p] is the radionuclide activity concentration in phytoplankton (Bq [kg.sup.-1] f.w.); CF is the bioconcentration factor for phytoplankton (l [kg.sup.-1]); and [C.sub.w] is the radionuclide activity concentration in sea water (Bq [l.sup.-1]).

By comparing available measured data and model predictions to bioaccumulation criteria in Canada [i.e., bioconcentration factor (BCF) or bioaccumulation factor (BAF) [greater than or equal to] 5,000], approximately 1,240 organic chemicals on the DSL were identified as potentially bioaccumulative (Environment Canada 2006; Persistence and Bioaccumulation Regulations 2000).
In turn, its bioconcentration factor decreased as the applied Pb concentrations increased.
