The Pоtоmаc River cоntаins аn average concentration of 55 ng/L of polychlorinated biphenyls (PCBs). Fish in the Potomac River are found to contain PCBs that they accumulate from water. Considering a bioconcentration factor (BCF) for PCBs of 1,500 L/kg in fish tissues relative to water, estimate the concentration of PCB in fish (in ng/kg) in the Potomac River. Considering a Maximum Daily Intake (TDI) of 20 ng/kg/day, estimate the maximum amount of fish (in g) that a 70-kg person can consume per week. Indicate the major steps of your calculations, so I can give you some credit even if your final answer is not correct.
