Abstract:

Threats associated with the production, storage and use of warfare agents containing high explosives against the backdrop of political and social events emerging in the 21st century present new challenges for specialized laboratories involved in detecting contamination and identifying its source. A common analytical problem in studies conducted in the ecosystem is the low concentration of the test substance – below the detection limit of the instrument. Helpful in solving this dilemma are accumulation bio-markers, which appear to be an excellent tool for detecting contamination in, for example, flowing water. Such biomarkers make it possible to determine the presence of specific chemical agents at the same time they are a sensitive indicator of the ecosystem's response to contamination. The presented chromatographic method allows quantitative and qualitative determination of 2,6-diamino-4-nitrotoluene, 2,4-diamino-6- nitrotoluene, 1,3,5-trinitrobenzene, trinitrotoluene, 2-amino-4,6-dinitrotoluene, 4-amino-2,6-dinitrotoluene and tetryl in the biological matrix. The effects of accumulation in the tissue of crustaceans on TNT test solutions were studied from 1 to 24 hours. The saturation effect was observed and the concentration of TNT derivatives was measured. The observed effects confirmed the usefulness of the selected larva as a bio-indicator of TNT contaminant accumulation in the ecosystem.
