Article Synopsis
- The study assessed the toxic effects of various explosive compounds (TNT, TNB, 2,4-DNT, and 2,6-DNT) on terrestrial plants like alfalfa, Japanese millet, and perennial ryegrass in Sassafras sandy loam soil through seedling growth and biomass measurements.
- After 13 weeks of weathering and aging the soils, the findings revealed that dinitrotoluenes were more harmful to the plants in freshly amended soils compared to TNT and TNB.
- Aging and wetting-drying cycles altered toxicity levels, initially promoting growth at low concentrations before inhibiting it at higher levels, showcasing phenomena known as hormesis.
Monocyclic nitramine explosives such as 1,3,5-trinitro-1,3,5-triazacyclohexane (RDX) and octahydro-1,3,5,7-tetranitro-1,3,5,7-tetrazocine (HMX) are toxic to a number of ecological receptors, including earthworms. The polycyclic nitramine CL-20 (2,4,6,8,10,12-hexanitro-2,4,6,8,10,12-hexaazaisowurtzitane) is a powerful explosive that may replace RDX and HMX, but its toxicity is not known. In the present study, the lethal and sublethal toxicities of CL-20 to the earthworm (Eisenia andrei) are evaluated.
