Until recently, the only viable method of specifically measuring benzene at environmental levels (10 – 50 ppb) was through the use of grab samples and GC/MS. Recent advances in UV-DOAS techniques have led to the availability of such measurements on a one-second response time in a portable format which allows a rapid survey from a mobile vehicle.
