The lаke cоntаins аn average cоncentratiоn of 35 ng/L of tetracholorethylene (PCE). Fish in the lake are found to contain PCE that they accumulate from water.Considering a bioconcentration factor (BCF) for PCE of 530 L/kg in fish tissues relative to water, estimate the concentration of PCE in fish (in ng/kg) in the lake.Considering a Maximum Daily Intake (TDI) of 5 ng/kg/day, estimate the maximum amount of fish (in kg) that a 70-kg person can consume per week.Please show the details of your calculations so I may give you partial credits in case your final answers are not correct.
