Lethal effects of the explosives RDX and HMX were assessed using ten-day water exposures to juvenile sheepshead minnows (Cyprinodon variegatus). For RDX, maximum mortality occurred during the first two days of exposure with a 10-d median lethal concentration (LC50) of
The dissolution of the 2,4,6-trinitrotoluene (TNT), hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX), and octahydro-1,3,5,7-tetranitro-1,3,5,7-tetrazocine (HMX) from microscale particles (<250μm) of the explosive formulation Composition B was examined and compared to dissolution from macroscopic particles (>0.5mm). The dissolution of explosives from detonation soot was also

We apply a simple strategy for calculating from first principles a thermodynamically complete equation of state for molecular crystals using readily available quantum chemistry techniques. The strategy involves a combination of separate methods for the temperature-independent mechanical compression and the
A novel geometry-independent neutral desorption (GIND) device was successfully developed, which made neutral desorption (ND) sampling easier and more robust on virtually all types of surfaces. The GIND device features a small air-tight enclosure with fixed space between the ND

Sheepshead minnows (Cyprinodon variegatus) were exposed to radiolabeled isotopes of the explosives 2,4,6-trinitrotoluene (TNT), exahydro-1,3,5-trinitro-1,3,5-triazine (commonly known as RDX), and octahydro-1,3,5,7-tetranitro-1,3,5,7-tetrazocine (commonly known as HMX), yielding the bioconcentration factors (BCF) of 3.3, 0.7, and 0.1 L kg(-1), respectively. For TNT
