TOXICITY OF SEDIMENT-ASSOCIATED NITROAROMATIC AND CYCLONITRAMINE COMPOUNDS TO BENTHIC INVERTEBRATES

摘要

The toxicity of nitroaromatic(2,4-diaminonitrotoluene [2,4-DANT]and 1,3,5-trinitrobenzene[TNB]and ~14C-labeled cyclonitramine compounds(hexahydro-1,3,5-triazine [RDX] and octahydro-1,3,5,7-tetranitro-1,3,5,7-tetrazocine [HMX]to the marine polychaete Neanthes arenaceodentata and the estuarine amphipod Leptocheirus plumulosus following 10- or 28-d exposures to spiked sediments was investigated. Organismal-level effedts on survival, growth, and reproduction and cellular- level effects on apoptosis(programmed cell death)were evaluated.
