Methodenlisting
Auswertung (Statistische Methode) To estimate the median lethal concentration (LC50) we used a computerized program developed at SRI and composed of several statistical methods for estimating LC50s and EC50s. For this project, we chose' estimates derived only from the log-probit or binomial methods. The specific method we chose depended on the number and pattern of partial responses , (i.e., >0 percent, <100 percent). Analytik der Testsubstanz HPLC. The instrument (Spectra-Physics, Model 3500B) was equipped with a 3.9 m by 30 cm C1 8 - Bondapak colunn for the analysis of TNT, RDX, TNT/RDX, and DNA. and with a 3.9 mm x 30 cm Spherisorb ODS column for the analysis of THB and TNBA. Various mixtures of methanol and water were used as eluting solvents. All analyses were perforu.ad by direct injection of the aqueous samples into the chromatograph. Table 5 presents the HPLC parameters for those toxicants.
