From 435e07a6f7fd2599d783fd306ee6d9e08acc0c6b Mon Sep 17 00:00:00 2001 From: Johannes Ranke Date: Fri, 27 Sep 2019 10:00:15 +0200 Subject: 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 --- docs/reference/EFSA_washoff_2017.html | 198 ++++++++++++++++++++++++++++++++++ 1 file changed, 198 insertions(+) create mode 100644 docs/reference/EFSA_washoff_2017.html (limited to 'docs/reference/EFSA_washoff_2017.html') diff --git a/docs/reference/EFSA_washoff_2017.html b/docs/reference/EFSA_washoff_2017.html new file mode 100644 index 0000000..1f7bce7 --- /dev/null +++ b/docs/reference/EFSA_washoff_2017.html @@ -0,0 +1,198 @@ + + + + + + + + +Subset of EFSA crop washoff default values — EFSA_washoff_2017 • pfm + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
