Concentration of compound		Duration of test, days	Elimination (%)			Period of average, days
mg/l	mg TOC/l		3 hrs	Average	Range
3000*	400	14	0	95	94- 96	6 -14

* soluble in cold tap water: 2345 mg, of which the solute part was 400 mg TOC/l , thus only the elimination of the dissolved part was determined.
