“…In more recent years, growing concern about the health and ecological threats posed by man-made chemicals have led to studies of the toxicology of explosives, which have identified toxic and mutagenic effects of the common military explosives and their transformation products (Bruns-Nagel et al, 1999a;Fuchs et al, 2001;Homma-Takeda et al, 2002;Honeycutt et al, 1996;Rosenblatt et al, 1991;Spanggord et al, 1982;Steevens et al, 2002;Tan et al, 1992;Won et al, 1976). Because the cleanup of areas contaminated by explosives is now a public health concern, considerable effort has been invested in finding economical remediation technologies.…”

“…This large-scale production led to the disposal of wastes containing explosives and nitrated organic by-products into the environment. In the US, the Army alone has estimated that over 1.2 million tons of soil have been contaminated with explosives (Hampton and Sisk, 1997b), and the impact of explosives contamination in other countries is illuminated by literature references from Germany (Bruns-Nagel et al, 1997), Canada (Cattaneo et al, 1997), Australia (Toze et al, 1997), Spain (Duque et al, 1993), Argentina (Fuchs et al, 2001)and England (Binks et al, 1995).…”

“…In Argentina, soils of an area in which an explosive manufacturing plant has been operating for 50 years were highly contaminated with TNT and in need of remediation. TNT concentrations in sediments of the wastewater disposal lagoon ranged from 7-800 mg/kg (Fuchs et al 2001).…”

Contamination by 2,4,6-trinitrotoluene (TNT) is a global environmental problem at sites of former explosive production, handling, or storage, and could have deleterious consequences for human and ecological health. We investigated its sublethal effects to Eisenia fetida, using two nonspecific biomarkers. In coelomocytes of earthworms exposed 24, 48, or 72 h, we evaluated DNA damage (comet assay) and neutral red retention time (NRRT), using the filter paper contact test. Both percentage of damage (D%) and calculated damage index showed significant DNA damage at almost all concentrations, at all time points assayed. Along exposure time, two different patterns were observed. At the lower TNT concentrations (0.25-0.5 μg/cm2) an increased DNA migration at 48 h, with a decrease close to initial levels after 72 h exposure, was observed. This decrease could be attributed to activation of the DNA repair system. At higher concentrations (1.0-2.0 μg/cm2), the high DNA damage observed remained constant during the 72 h exposure, suggesting that the rate of DNA repair was not enough to compensate such damage. Analysis of NRRT results showed a significant interaction between time and treatment. After 48 h, a significant decrease was observed at 4.0 μg/cm2. After 72 h, NRRT presented a concentration-dependent decrease, significantly different with respect to control at 0.5, 1.0, 2.0, and 4.0 μg/cm2. The two assayed methods, performed on the same sample, showed clear responses to sublethal TNT exposure in E. fetida, providing sensitive unspecific biomarkers of cell injury and DNA damage.

“…The nitroaromatic explosive, TNT, was among the most abundantly produced explosive manufactured worldwide over the last century. Its release to surface water and groundwater has been mostly from runoff and leaching from storage and disposal areas, as well as release from receiving lagoons at munitions production and processing facilities (Fuchs et al, 2001). Reduction of the nitro-groups to amino-groups typically follows introduction of TNT to soils (Pennington and Brannon, 2002) and sediments .…”

a b s t r a c tThe bioaccumulation potential and toxicity of 2,4,6-trinitrotoluene (TNT) spiked to sediment was evaluated in juvenile sheepshead minnows (JSHM, Cyprinodon variegatus) and adult freckled blennies (FB, Hypsoblennius ionthas). The JSHM were exposed for 4 days in the presence or absence of a mesh separating fish from sediment. FB were exposed to sediment for 7 days. During the 24-day storage period (4 1C), extensive transformation of spiked TNT occurred and concentrations are expressed as the sum of TNT, aminodinitrotoluenes and diaminonitrotoluenes (SumTNT), on a dry weight basis. SumTNT in the overlying water, not exchanged during exposure, increased gradually. Survival was high (Z 90%) for JSHM exposed to 7 mg kg À 1 and FB exposed to up to 260 mg kg À 1 . All SHM died after 24 h exposure to 340 mg kg À 1 . Isolation from sediment did not significantly affect water concentrations or decrease bioaccumulation. Uptake from contact to sediment was likely negligible and bioaccumulation was from the overlying water. The feeding rate of FB exposed to 1700 mmol kg À 1 sediment suspended in water for 24-h was significantly reduced by 50%.Published by Elsevier Inc.
