A one and one-half year-old male of migrant farm workers was hospitalized because of weight loss, vomiting, and acute abdominal pain.  It was noted that the child had mild muscular incoordination, weakness of the pedal dorsiflexor muscles, moderate hypertension, and questionable edema of the optic nerve ends.  Microscopic examination of a blood smear showed a moderate but distinct increase in the reticulocyte count.  Both his hematocrit and RBC were slightly below normal.  All liver function and renal function tests were essentially normal.Note:  The pedal dorsiflexor muscle controls the lifting of the foot and toes upward and is a common marker of muscular weakness (foot flop).What was this child exposed to?

Describe at least 2 important toxicological facts about the following.PCBs

A group of people visited the reading room in the community library and spent time sitting and reading.  There was an accidental spill of a toxicant called Omega, which is highly volatile and absolutely odorless, in the ventilation system for that library room.  Once the staff realized what had happened, the air concentration of Omega was determined to be 0.648 ug/L.  But they need to know what dose these individuals received to determine the risk of health issues arising in the library’s cliental, and they hire you as the imminent Toxicologist to answer this question.You are told that there were 12 visitors, each visitor weighed about 70 Kg on average and stayed about 90 minutes in the reading room.  You also know that people breath approximately 6 liters of air per minute. Calculate the Dose each library visitor received.  You must show your work to receive full credit.(Note:  Assume: 1) total absorption of agent Omega from each breath; and 2) agent Omega reached an equilibrium within the room’s air volume within a few seconds of release.)
