“…An example is the use of geometric means in establishing the foliar-to-dermal residue transfer rate (TR), a parameter critical to the calculation of reentry dermal exposure (RDE). The foliar component of the TR is the dislodgeable portion, referred to as dislodgeable foliar residues (DFR).The conventional algorithm for RDE is: RDE current ¼ DFR current  TR (e.g., van Hemmen et al, 2001), where TR is typically the ratio of RDE trial to DFR trial measured in a trial. RDE consists of residues transferred to the workerÕs body from contact with treated foliage.…”
