Parameter | Definition | Unit |
---|---|---|
F mt | Formation fraction of the metabolite to parent | – (unitless) |
F tr | Fraction of metabolite formed in the respective matrices (% of total radioactive residues) | – (unitless) |
M mt | Molar mass of the metabolite | g |
M pr | Molar mass of the parent molecule | g |
PEQ di |
Predicted Exposure Quantity due to dietary exposure, i.e. the intake of pesticide mass per bee. This is the output of the exposure estimation. For the chronic adult assessments, this quantity must be expressed per day, but for the larvae it must be expressed as the sum of the intake over the entire developmental period. In other parts of the guidance document, PEQ is indexed with a ‘j’. ‘j’ is referring to the risk case like acute, adult chronic or larvae. |

AR | Application rate | g/ha |
B | Factor depends on the category and the application method | μg/bee or μg/bee per day or μg/larva/developmental period in days |
n be | Number of applications before flowering | – (unitless) |
n du | Number of applications during‐flowering | – (unitless) |
n | Total number of applications before and during‐flowering (nbe + ndu) | – (unitless) |
EF di | Exposure factor for dietary exposure | – (unitless) |
SV po,be | Shortcut value for pollen for before flowering situations | μg/bee or μg/bee per day or μg/larva/developmental period |
