  1. Pesticides are classified as fungicides (F), herbicides (H) and insecticides (I). The intended concentrations (nominal concentrations) are equivalent to RAC regulatory acceptable concentration (status 2014), AI active ingredient, AN application number, DF dosing factor, DMS dimethylammonium, ED experimental day, IPA isopropylamine, LOQ limit of quantification, na not analysed, PPP plant production product, RDS recovery of AI in dosing solution, WG dispersible granules,
  2. Water Conc. in streams = mean of measured AI concentration in water of the streams; Recovery of AI in streams = mean of water conc. divided by target concentration (RC)
  3. aRDS = Cstock* (RC*DF*Vwater)−1; Vwater = Volume of water in the stream at time ED; Cstock = measured concentration of dosing solution
  4. bConcentrations in g/L for fluids
  5. cDosing factor was used in order to obtain the target concentration in the dosing solution, the dosing factor was applied on the product
  6. dFor combi-product, RAC derivation is based on only one active substance; RAC by date 2014-07-25
  7. eNo values due to defect in analyser
  8. fValue in brackets is the measured concentration without correction of preload concentration (Application Number 11)
