SPEARpesticides
2021.02
- German translation added for labels and documentation
- Updated quality classes with the following five levels:
| EQpesticides | SPEARpesticides |
|---|---|
| High (I) | >= 0.8 |
| Good (II) | >= 0.6 ... < 0.8 |
| Moderate (III) | >= 0.4 ... < 0.6 |
| Poor (IV) | >= 0.2 ... < 0.4 |
| Bad (V) | >= 0.0 ... < 0.2 |
- Calculation of TUestimated changed to:
TUestimated = (0.17502 - SPEARpesticides) / 0.13012 - Updated normalization factor for SPEAR (NEW: 0.44, OLD: OLD 0.27)
For details see:
- Liess et al. 2021
- 'Determination of SPEARpesticides quality classes' in the Supporting Information of Liess et al. 2021
2019.11
- Fixed a bug in the log-transformation of abundance data (Correct: log10(4 * Abundance + 1) ). The bug was previously introduced in version 2019.10.
2019.10
- Renaming of the calculation file to 'SPEARpesticides' (OLD file name: 'SPEARpesticide')
- Updated trait table
- Changed log-transformation of abundance data ( log10(4*(Abundance+1)) )
- Updated normalization factor which is quantified as the averaged SPEAR-value for uncontaminated reference sites (NEW: 0.27, OLD: 0.31)
- Fixed bug in the classification rule for the SPEAR trait 'sensitivity' (NEW: trait value >= THRESHOLD, OLD: trait value > THRESHOLD)
- Class boundaries of EQpesticides are rounded to 2 decimal places
- Updated quality classes with the following five levels:
| EQpesticides | SPEARpesticides |
|---|---|
| High (I) | >=0.98 |
| Good (II) | >=0.76 |
| Moderate (III) | >=0.55 |
| Poor (IV) | >=0.34 |
| Bad (V) | < 0.34 |
