Field Study Conduct

In the ARTF worker reentry exposure studies, workers were dressed in standard clothing while they performed their normal activities after a field was sprayed with a surrogate compound. At the end of the day, the amount of dermal exposure was determined by measuring the amount of surrogate residue on the inner and outer clothing, the face/neck area, and hands. Inhalation exposure was determined by measuring the amount of surrogate collected on air sampling tubes attached all day to an air pump.  At the same time, DFR measurements were determined from leaf samples collected from the crop and washed in a detergent solution.

 

Field reentry studies were conducted on activities within each of the crop/activity cluster groups. ARTF conducted 27 reentry exposure studies which, with the 18 purchased studies, provided enough generic TC data to complete the database.
