^aListed by limit of blank (LOB), number of measurements (N), arithmetic mean (AM), arithmetic standard deviation (ASD), GM, and GSD. N is reflective of each micronutrient tracer analysed via ICP-MS.

^bAs shown in Fig. 1, downwind sampling rows were at distances of 5 (near), 26 (mid), and 52 (far) m from the southern edge of the sprayed area. These correspond to Masts B–F (near), G–K (mid), and L–P (far).

^cGM drift volume levels measured for AFA, DAT, and MFT sprayers at 52 m downwind were 2.0 (20/10), 3.4 (17/5), and 3.3 (13/4) times greater than background levels measured at the upwind reference location (Mast Q) (Supplementary Table S2, available at Annals of Work Exposures and Health online).
