Additional information
A water solubility was estimated using structure activity relationships models developed by the U.S. Environmental Protection Agency and
Experimental water solubility was determined by (Reimer 2001e). The f
lask method based on OECD Guideline 105 was used. TNPP was not detected in the saturated aqueous test solution. Therefore it is concluded that the water solubility of TNPP is below the detection limit of the substance. This detection limit was estimated to be 0.6 mg.L-1 at 24°C, the lowest TNPP concentration that produced a signal that is reliably distinguished from the background signal as determined from chromatograms of TNPP solutions. Atest employing a more sensitive analytical method for measuring TNPP established a new LOQ of 0.05 mg.L-1 (reference). Solubility measurements have been attempted using this new analytical method. Considering the first results of this experiment, it seems that water solubility is around or below this analytical limit (TNO, personal communication). This value was used in the October 2008 draft EU RAR for quantative assessment. The October 2008 draft RAR also included a sensitivity analysis on the range for water solubility between ~0.05and 3x10-16mg/L. The lower end of this range comes from modeled results using WSKOW and a range of log Kow values.
