Exposure home gardener

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,... 

Diazinon is widely used for agricultural purposes, and residues on or in foods can result in exposure of humans by ingestion. Additional exposure potentials exist as a result of home gardening activities. Consequently, methods for the determination of diazinon in biological samples can be used to verify that exposure and absorption have occurred. Since diazinon is rapidly metabolized, determination of the parent compound can provide evidence only of very recent exposures (see Chapter 2). Methods have been reported for metabolites, and these are discussed below under Biomarkers of Exposure. A few papers were found that deal with the determination of diazinon in human samples and these are described below. Some methods have reported the determination of diazinon in animal tissue or other...

Thiram is a broad-spectrum fungicide and is found in most home-garden formulations whereby day-to-day human exposure can occur. Its use in various industries leads to multiple avenues for occupational exposures. The highest exposures occur in workers utilizing and/or manufacturing this compound. Exposure to thiram can occur via inhalation, ingestion, and eye or skin contact.

Comparison with Commercial Application. We found applicator exposure in home gardens to be considerably less than that found in commercial orchard spraying as the 3 studies cited below show. All used air-blast spraying of carbaryl ... 

In 1962 in Quebec ( ), the dermal exposure was found to be 6.3 mg/15 min. as a mean of 7 subjects the range was 4.6-7.6. The exposure was determined by the adsorption to forehead and wrist pads. This approximated the long-sleeved regimen where our home gardener received a much lower 0.2-0.3 mg/15 min. for high plants ... 

The total yg per body areas was calculated from the yg/cm determined per pad times the area of the body considered as expressed In Table I The yg/hr was calculated by multiplying the total yg/body area by 60 (minutes) and dividing by the exposure time (minutes). The total yg/Kg body wt/day assumed a spraying day of 6 hours for commercial applicators and one hour for home gardeners and a 60 Kg average body weight. 

Table IX presents the exposure of persons Involved In the ground application of mancozeb by an alrblast sprayer to a tomato field In Ohio. Mixer-loaders again experienced exposure to mancozeb with forearms predominating (2856-3485 iig/body area). Tractor driver—applicators did not experience much exposure, but forearms did range from nondetectable to 1090 yg/body area. Home gardeners using a compressed air sprayer In a homeyard setting experienced little exposure to mancozeb (Table X), except for their ankle and thigh pads (nondetectable-4290 yg/body area).
