1 Kd calculated from measured Cw and Cs,
2
Kd calculated from measured Cw and calculated Cs where Cs = C-control - Cw.
3 Cs is given as measured Cs in the sediment sample corrected for the amount of pesticide present in the water
that was evaporated prior to counting (the pesticide concentration in the evaporated sediment water is
assumed to be equal to measured Cw in the supernatant).
4 Cs in the unit [dpm/L] is calculated as Cs[dpm/kg dry weight] CP [kg dry weight/L slurry] where CP is
sediment concentration.
5 CT = Cs+Cw.
6 Recovery is calculated as CT/CT-nominal.
1 Kd beregnet ud fra målt Cw og Cs,
2
Kd beregnet ud fra målt Cw og beregnet Cs hvor Cs = C-control - Cw.
3 Cs angives som målt Cs i sedimentprøven korrigeret for den mængde pesticid, som var tilstede i det vand,
som blev afdampet inden tælling (pesticidkoncentrationen i det afdampede sedimentvand antages at være lig
med målt Cw i supernatanten).
4 Cs i [dpm/L] er beregnet som Cs[dpm/kg tørvægt] CP [kg tørvægt/L slam] hvor CP er sedimentkoncentration.
5 CT = Cs+Cw.
6 Genfinding er beregnet som CT/CT-nominel.
