Graphical Representation

Description

Parent 1-NAA shows a rapid degradation with a DT50 probably < 3 days and a DT90 probably < 9 days. One main metabolite seems to be relevant (>10%: Naphtoic acid found up to 24.7% of applied radioactivity. It shows a rapid degradation (DT50 < 6 days). Some transient metabolites are also found in soil: - Naphtalene-1-carbaldehyde (up to 8.6% at day 0, and 3% at days1); - 1-Naphtalene methanol (up to 3.8%); - 1-methylnaphtalene (0.8%).
