Nitroaromatic Munition Compounds: Environmental Effects and Screening Values

“…Although TNB is only slightly soluble in water, 0.34 giL at 20 °C (Spanggord et al 1980a), it has been found in surface water and groundwater. Sullivan et al (1978) measured TNB in Waconda Bay, the receiving water body of the Volunteer AAP, TN. The concentrations in the water ranged from <0.75 Jlg/L (the limit of detection) to 66 Jlg/L, and concentrations in the sediment ranged from 73 J.Lglkg to 300 Jlg/kg.…”

“…Only nondetectable to low concentrations occur in surface water and groundwater at AAPs (Walsh 1990). Sullivan et al (1978) measured DNB in Waconda Bay, the receiving water body of the Volunteer AAP, TN. Concentrations in the water ranged from below the limit of detection (1 )..lg/L) to 6 J..Lg/L; concentra-tions in the sediment ranged from <6.3 to 14 Jlglkg.…”

Genomic investigation of year-long and multigenerational exposures of fathead minnow to the munitions compound RDX

“…Our study provides a strong indication that an extended longterm chronic exposure (one year) to RDX at a concentration (mean concentration, 0.83 mg/L) representing a high-end dose based on environmental monitoring studies [15,16] posed marginal risk to the individual fathead minnows and did not affect reproduction. Continuous RDX exposure through the F 2 generation was not observed to appreciably enhance RDX tolerance versus control-reared fish in a 96-h RDX challenge.…”

“…Our study represents an ambitious effort to assess the potential impacts of an environmentally relevant concentration of RDX [15,16] on fathead minnow over the course of a oneyear exposure and in the F 2 generation of fathead minnow exposed continuously to RDX. Although RDX accumulated in both brain and liver tissues (Fig.…”

“…Reported concentrations in surface waters are generally in the mg/L to low mg/L range. For example, Sullivan et al [15] reported a concentration of 0.7 mg/L RDX immediately below and <0.005 to 0.07 mg/L one mile below the outfall of the Volunteer Army Ammunition Plant (TN, USA). Hewitt et al [16] found aqueous RDX concentrations ranging from 0.00088 to 0.0029 mg/L in a stream located on an air-to-surface firing range.…”
