Monitoring methodMonitoring method To find the
quantity of absorbed benzene we used a device called

ConclusionsConclusions
•The results that we have had, are as we expected:
•High absorption by some subjects, higher than the maximun permitted,
•High concentration in locations with a lot of traffic,
•Concentration lower than the limit in subjects who work in locations poor of benzene.
