Sprayers potential applicator exposure

Drop nozzle application is a situation in field crop maintenance where the addition of a spray cab might be expected to significantly reduce potential applicator eiq>osure. Alternatively, the use of other boom sprayers (HPHB, HPLB, LPLB) appear to give less exposure than the drop nozzle rigs. 

In addition to its presence in the ambient atmosphere, diazinon also has been monitored in both outdoor and indoor air associated with its use in a variety of domestic, commercial, and occupational exposure situations. Exposure to diazinon from its use in lawn and home garden applications was evaluated by Davis et al. (1983). Diazinon was mixed with water and sprayed using compressed air sprayers or hose-end sprayers, and potential respiratory and dermal exposures were estimated from residues collected from respirator filters, body pads, and hand rinsings. These authors reported mean respiratory exposures of 1.9,...
