Fix for UK drainage, some EFSA interception and washoff
- PEC_sw_drainage_UK() gave results that were a little bit too high
for the substances with the highest Koc (>4000), as I used 0.01% instead
of 0.008% for them. This must have come from an old vesion of the UK
data requirements handbook, at least I do not have another explanation
- Add EFSA interception (from 2014 DegT50 guidance) and tier 1
crop wash-off factors (from 2017 PEC soil guidance) for some major
arable crops
- Update docs
