Occupational exposure/risk (MOE) for tasks associated with Furadan® 3G applications to rice, using a single layer with no glovesa
| Crop | Application scenariob | Application ratec (g AI ha−1) | Area treated (ha day−1) | Dermal exposured (µg kg day−1) | MOEe |
|---|---|---|---|---|---|
| Rice | ‘Push-type’ granular spreader (open pour)—M/L/A | 1875 | 2 | 342.50 | 196 |
| Rice | Solid broadcast spreader, open cab, Ag uses—open M/L | 1875 | 80 | 39.68 | 1688 |
| Rice | Solid broadcast spreader, open cab, Ag uses—A | 1875 | 80 | 46.77 | 1433 |
a
Mixer/loader: an open mixing and loading system. Applicator: a single layer (long-sleeved shirt and long trousers) with no gloves.
b
M/L/A = Mixer/loader/applicator; M/L = mixer/loader; A = applicator.
c
Maximum listed label application rate in g AI ha−1.
d
Dermal exposure = (unit exposure × area treated × application rate) 70 kg−1.
e
Based on a dermal BMDL10 of 67.0 mg kg−1 day−1 = 6.7 mg kg−1 day−1 × 10 (relative rat/human dermal penetration factor for Furadan® 5G and a target MOE = 100).
