Therefore, the consumption of any plant tissues growing on RDX-contaminated sites should be considered a potential health hazard.Explore the Nectar - Barbur menu on Leafly. Although RDX is not a listed carcinogen, several of its potentially present degradation products are carcinogens. ![]() The compound RDX was found in the tops and roots of plants growing on RDX-contaminated soils at all surveyed sites. However, soil and plant roots may contain TNT degradation products that may be toxic hence, their consumption is not advised. The compound TNT was not detected in the aboveground portion of plants, and vegetation growing more » on TNT-contaminated soils is not considered a health hazard. ![]() Standard methods were used to determine the concentrations of explosives, their derivatives, and metabolites in the soil samples. To determine explosives uptake under natural environmental conditions, existing plant materials and soil from the root zone were sampled at different locations in each area, and plant materials were separated by species. This study examines the uptake of explosives by existing vegetation growing in soils contaminated with 2,4,6-trinitrotoluene (TNT) and 1,3,5-trinitro-3,5-triazine (RDX) in three areas at the Iowa Army Ammunition Plant (IAAP). This study presents a simple, relatively inexpensive methodology for assessing toxicity of soils containing TNT, RDX, and other contaminants related to munitions production. Lowest-observable-effect concentrations (LOEC) of TNT were determined from these data. chemical concentrations showed that TNT and TNB accounted for most off the soil toxicity. Linear regressions of toxicity test results vs. However, some soils void of munitions still showed toxicity that may have been caused by elevated levels of heavy metals. All soils with no significant toxicity were void of these chemicals. Chemical residues found in soils were 2,4,6-trinitrotoluene (TNT) 1,3,5-trinitrobenzene (TNB) 2,4-dinitrotoluene (2,4-DNT) 2,6-dinitrotoluene 2-amino-4,6-DNT 4-amino-2,6-DNT 1,3,5-trinitro-1,3,5-triazine (RDX) and octahydro-1,3,5,7-tetranitro-1,3,5,7-tetrazocine (HMX). Soil that had significant toxicity according to at least one test, and representative samples showing no toxicity, were analyzed for munitions via HPLC. Samples were designated as having high, moderate, or no significant toxicity. Relative toxicity of soils was determined within each area based on statistical significant (p = 0.05) more » of plant and earthworm growth and survival, and the effective concentration at which luminescence of the bacterium Photobacterium phosphoreum was reduced by 50% (EC50) in the Microtox assay. ![]()
