In water, does not adsorb strongly to soil and migrates further in contaminant plumes in ground-water. It is not bioaccumulative in plant or animal tissues but can be taken up by plants from contaminated soils, thus small amounts could be transferred up the food chain Plant species have been found to die in RDX contaminated soils at concentrations of 580 mg kg−1. Studies into the phytotoxicity of RDX indicate a lethal concentration in water of 5 to 6 mg L−1 with stunted growth of emergent species experienced at concentrations of 1.5 mg L−1. HMX Adsorbs to soil to a lesser degree than TNT, is more soluble than RDX and is resistant to biodegradation in aquifers. Degradation and its breakdown products have rarely been found in the environment. Potential to cause liver and central nervous system damage but it is not known whether it causes cancer or reproductive problems in animals. ExplosiveEnvironmental propertiesaEnvironmental consequencesaTNT Fast dissolution rate, adsorbs strongly to soil but also degrades readily. Depending on soil characteristics, these breakdown products are either more mobile than, or have a similar mobility to, TNT. TNT can be taken up by plants from contaminated soil, including edible varieties of garden plants, aquatic and wetland plants, trees, and can accumulate in plant roots. Lethal concentration of TNT to plants in water is 5000 μg L−1. Phytotoxicity from contaminated soil is dependant on soil properties, for example, plant yields are significantly reduced in silty soils when TNT concentrations reach 200 mg kg−1 but no effects are observed at concentrations of less than 400 mg kg−1 in clay. Laboratory research has also shown that TNT concentrations in soil greater than 9000 mg kg−1 result in no surviving earthworms, whilst male animals treated with high doses of TNT have developed serious reproductive system effects.
