Part 2. In a research paper (Koelmans et al. 1996) the sorption behavior of metals to algal particulate matter was evaluated in a series of different salinities. The following data were obtained from sorption experiments between algal particulates and Cd solutions (the same algal particulates were used in both experiments). The Freundlich isotherm was found to be the best model for the data. The isotherms were generated by expressing Cs in units of µg/g and Caq in units of µg/L.Site Cl- (mg/L) Kf nHD 100 16.9 0.83NS 16 000 0.73 0.771. If the concentration of Cd in water at the HD site is 23 ?g/L what is the concentration of sorbed Cd on the algal particulates in ?g/g?2. If water and algae from HD site flow downstream to the NS site will the algal particles release or adsorb Cd? Defend your answer numerically.
