Question

5.4 mg of Toluene was collected at a rate of lpm for 8 hours. what is the concentration the worker was exposed to?

science chemistry

Answer 1

Answer #1

concentration the worker was exposed

= [5.4 mg/(L-min)] x (60 min/hr)

= 324 mg/(L-hr)

1 mg/L = 1 ppm

= 324 ppm/hr

For 8 hours

= 324 x 8

= 2592 ppm

Permissible Exposure Limit for toluene for 8-hour = 200 ppm

14. Gentamicin is often given in IV-bolus doses of 100 mg every 8 hours to achieve an average steady-state plasmatic concentration of 5 mg/L. The total clearance is normally 5.4 L/h in a 70 Kg-body weight person. Gentamicin is entirely eliminated by glomerular filtration. Your patient, however, is found to have a creatinine clearance one-third of normal. Your initial dosage regimen for this patient would probably be: a. 20 mg every 8 hours b. 33 mg every 8 hours c....
