This is a true story. a lawyer in bloomington, indiana, wanted to impress a judge with the high number of pcb molecules that a typical person takes in with each breath. he called prof. hites for this fact, but he did not have this information at hand. however, a student of his had recently determined that the flux of pcbs from the atmosphere to bloomington's surface averaged 50 μg m^(-2) y^(-1). you may assume that the area of bloomington is 100 square miles, that the deposition velocity of pcbs is 0.3 cm/s, and that the molecular weight of pcbs is 320. what would you tell the lawyer?
