Changes in the aqueous solubility of nitramine and nitroaromatic explosives in response to variations in common environmental parameters were investigated. Initial experiments focused on the cosolute effects of mixing explosive compounds together, and solubility differences produced by the presence of syringic, humic, and linolenic acids, and albumin. Aqueous solubility was determined using natural waters of different types. Effects of pH changes were also determined. Increasing humic acid concentrations increased TNT and TNB solubilities by 10--20%, compared to solubility in distilled water. Maximum increase occurred with humic acid concentrations of 96.8 and 152 mg L{sup {minus}1} for TNT and TNB, respectively. Syringic and linolenic acids, albumin, and pH changes had no apparent effect on the nitramines and nitroaromatics tested. Results were similar using natural and distilled waters.
