Calibration of Models Describing Pesticide Fate and Transport in Lillebæk and Odder Bæk Catchment

Table 6.6 Mean, standard deviation and fractile values derived for four pesticides. If values were available from the PATE-database and from other sources (in the case of Bentazon and isoproturon), values have been calculated both for the PATE-values alone and for the combined dataset.
Tabel 6.6 Gennemsnit, standardafvigelse og fraktilværdier udledt for de fire pesticider. Hvis værdier fandtes i PATE-databasen og fra andre kilder (i tilfældet bentazon og isoproturon, er værdierne beregnet både for PATE-værdierne alene og for det kombinerede datasæt.
