CL-20 is an emerging munition compound that may replace RDX and HMX, but little information is available on its environmental fate and ecological impact. Therefore the present report first describes the development and validation of an analytical method to analyze CL-20 in soil and water and the determination of key physicochemical parameters such as Kow (82.6), solubility (3.87 mg/L) and sorption/desorption parameters (Kd, Koc) of the chemical under various conditions ...
Enzyme catalyzed biotransformation of the energetic chemical octahydro-1,3,5,7-tetranitro-1,3,5,7-tetrazocine (HMX) is not known. The present study describes a xanthine oxidase (XO) catalyzed biotransformation of HMX to provide insight into the biodegradation pathway of this energetic chemical. The rates of biotransformation under aerobic and anaerobic conditions were 1.6 0.2 and 10.5 0.9 nmol h 1 mg protein 1, respectively, indicating that anaerobic conditions favored the reaction. The biotransformation rate was about 6-fold ...
