Synergetic toxic effect of an explosive material mixture in soil.

Panz K, Miksch K, Sójka T - Bull Environ Contam Toxicol (2013)

Bottom Line: The aim of the presented research was to assess the toxicity of forest soil contaminated with these substances both individually as well in combinations of these substances.Although RDX and HMX did not have adverse effects on plants, these compounds did cause earthworm mortality, which has not been reported in earlier research.Synergistic effects of explosives mixture were observed.

ABSTRACT
Explosives materials are stable in soil and recalcitrant to biodegradation. Different authors report that TNT (2,4,6-trinitrotoluene), RDX (hexahydro-1,3,5-trinitro-1,3,5-triazine) and HMX (octahydro-1,3,5,7-tetranitro-1,3,5,7-tetrazocine) are toxic, but most investigations have been performed in artificial soil with individual substances. The aim of the presented research was to assess the toxicity of forest soil contaminated with these substances both individually as well in combinations of these substances. TNT was the most toxic substance. Although RDX and HMX did not have adverse effects on plants, these compounds did cause earthworm mortality, which has not been reported in earlier research. Synergistic effects of explosives mixture were observed.

Fig2: Effect of different explosives concentrations on the root length of red clover and bread wheat weight (*statistically significant results, p ≤ 0.05)

Mentions: The analysis of root length demonstrated that 2,4,6-trinitrotoluene caused a significant decrease of root length in red clover and wheat in all applied concentrations. Hexogen and octogen did not cause significant decrease of red clover root length, but did cause a very strong increase of wheat root length. Significant inhibition of red clover root length was only observed in soil samples spiked with the highest concentration mixture of explosives; low concentrations caused wheat growth stimulation. Length of roots in 1,000 mg/kg concentration were significantly lower in comparison with the control samples (Fig. 2).Fig. 2
