Abstract
Abstract Triethylene glycol dinitrate (TEGDN) is an energetic plasticizer presently used in the synthesis of new insensitive formulations. However, little is known about its environmental fate and impact. In the present study, we measured several environmental physicochemical parameters that are necessary to predict the fate and impact of the chemical in the environment. High solubility of TEGDN in water (7,430 mg L−1 at 25 °C), its low log Kow value (0.79), and low Kd values (0.09–0.78 L kg−1) suggest that TEGDN will be very mobile in soils. We also investigated the kinetics and mechanisms of several degradation processes likely to occur in the environment. Hydrolysis and degradation in sterile soils were found to be very slow. No significant biological transformation was detected after 3-month incubation in soils under aerobic conditions. Photolysis was the fastest process to take place with a rate of 0.049 day−1 (t1/2 = 14 days) and 0.031 day−1 (t1/2 = 22 days) at 25°C in the dissolved or dry form, res...
