“…A number of researchers have described HPLC methods that use detection of ultraviolet (UV) absorption for the analysis of tetryl (Farey and Wilson 1975;Jenkins and Walsh 1987;Bongiovanni et al 1984). Several of these methods have been applied to the quantitation of explosives in soil extracts (Jenkins and Grant 1987;Jenkins and Walsh 1987;Bongiovanni et al 1984;Cataldo et al 1989Cataldo et al , 1990Harvey et al 1990, 1991) Palazzo and Leggett (1986 were the first to address the analysis of explosive residues in plant tissues. Since their initial report, only those methods described by Cataldo and co-workers (Cataldo et al 1989Harvey et al 1990Harvey et al , 1991 have significantly advanced the analytical methodology for determining explosives residues in plant tissues.…”
