Temporal dimension of EREQ |
See Table 30
|
|
Spatial unit (SU), type and size (if relevant) |
Individual amphibians |
This implies that each individual amphibian has its own in‐crop exposure depending, e.g. on migration day with respect to application day |
Statistical population of SUs |
All individual amphibians in all treated agricultural fields (generally around 1 to 5–10 ha) in area of use of substance |
Risk managers may also opt for the alternative of all individuals in all agricultural fields grown with the crop on the pesticide label |
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 |
|
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 |
