Appendix 5 Cadmium (Inorganic Salts) | Spacecraft Water
In this study, 34-d-old albino Sprague-Dawley rats (male and female) weighing about 100 g were given drinking water containing cadmium as CdCl 2 at 0.1, 0.5, 2.5, 5.0, 10.0, or 50.0 ppm. The study was conducted for 1 y except that the 50 ppm group was terminated at 90 d.

In a typical reaction, the salt of calcium was dissolved in 2:1 mixture of methanol and distilled water , then 0.15 g of sodium 2-mercaptobenzothiazole was added to the reaction mixture and the resultant reaction mixture was stirred for 1 h at 70 C°. After 1 h, solution of 1,10-phenanthroline was added to the reaction mixture and stirred for 2 h.

This leads to an overall production of (5.0 ± 1.0) × 10 18 oxygen during the ion irradiation phase, of which a fraction of (2.6 ± 0.3) × 10 −4 are accounted for by the detected D2-water molecules in the gas phase (SI Appendix, Table S3). The remaining oxygen remain in the silicates as oxides of magnesium and iron and/or react with the
