Profile 1 stands for a conceptual model for the tests product. Given that explained in more detail after, the fresh testing unit targets one or two significant pathways of inhalation exposure:

• droplet inhalation just after application and you may
• steam phase inhalation.

The newest evaluation device includes publicity out of droplet inhalation because of the calculating brand new quantity of pesticide dispersed over a defined area predicated on an enthusiastic believed duration of time your pesticide will stay regarding the heavens column. New evaluating equipment in addition to contact the potential volatilization regarding residues out of the latest addressed harvest canopy plus the ground by the figuring brand new theoretic restriction air attention at the a selected range over the treated industry. Vapor density are comparable to the fresh chemical’s saturation quantity on 25C and you may 1 surroundings, as calculated throughout the chemical’s vapor stress. Such assumptions write an upper-likely inhalation publicity well worth. Yet not, the model doesn’t target the new transport out-of particulate bound insecticides.

Computation of EECs and Future Data

The brand new publicity estimates derive from the type of app and you will exactly how much out-of a selected toxins is to be put on an area. Whether your software type of is through spray (both heavens otherwise surface), brand new unit quotes the droplet breathing together with steam stage breathing dosage. To own low-foliar software (we.e., granules, seed products therapy), the brand new screening tool only works out the steam phase inhalation dosage.

The most step one-time avian steam inhalation serving into the mg/kg (Formula step three) are a purpose of this new over loaded air amount (Picture step 1), the brand new inhalation rate (Equation 2), plus the bird pounds (assumed to get 0

The method regarding squirt application (both soil or sky) together with app rate influence the new droplet intensity of the latest chemical compounds floating around column directly immediately following software based on the height of one’s squirt line (step 3.step 3 meters to have aerial software, step 1 m getting surface software).
