For the times 1 and 3.5 hours, no controls were analysed but an average of the controls at 24 and 240 hours was used.   3 Cs=CT-Cw where CT is nominal.   4 Cs = Ccontrol-Cw. 1 Kd beregnet som Kd=(CT-Cw)/Cw hvor CT er nominel totalkoncentration.   2 Kd beregnet ud fra Kd=(Ccontrol-Cw)/Cw. Der blev ikke analyseret nogle kontroller for tidspunkterne 1 og 3,5 time, men et gennemsnit af kontrollerne for 24 og 240 timer blev anvendt. 3 Cs=CT-Cw hvor CT er nominel.   4 Cs = Ccontrol-Cw.
