Element | Description | Remarks |
---|---|---|
EREQ | See Table 32 | |
Temporal dimension of EREQ | See Table 32 | |
Spatial unit (SU), type and size (if relevant) | Individual amphibians | |
Statistical population of SUs | All individual amphibians in all off‐crops strips of land of x m wide in area of use of substance |
Risk managers may also opt for the alternative of all individuals in all off‐crop strips of land adjacent to fields grown with the crop on the pesticide label This implies that each individual amphibian has its own off‐crop exposure, depending on its distance to the treated crop |
Multiyear temporal statistical population of EREQ values for one spatial unit | Series of tens of years of annual maxima of EREQ of individual amphibians in years of treatment | Consider only EREQs in periods that are relevant, i.e. individual amphibians may be present in off‐crop strips of land |
Desired spatio‐temporal percentile of the statistical population of EREQ values | Overall 90th percentile of the statistical population of each EREQ | Percentile can easily be changed if needed |
