“…Trace radioactive uranium (U) is commonly found (Salama et al ., 2003) in the groundwater of numerous nuclear energy sites (Lin et al ., 2005) . Several reports indicate that 1.31~ 2.24 μg/ l of it is present in the coasts (Djogic et al ., 2001) .…”

Trace uranium detection measurement was performed using DNA immobilized on a graphite pencil electrode (DGE). The developed probe was connected to the portable handheld voltammetric systems used for seawater analysis. The sensitive voltammogram was obtained within only 30 s accumulation time, and the anodic stripping working range was attained at 100~800 μg/l U and 10~50 μg/l. The statistic relative standard deviation of 30.0 mg/l with the 15th stripping was 0.2115. Here, toxicological and analytical application was performed in the seawater survey in a contaminated power plant controlling water. The results were found to be applicable for real-time toxicological assay for trace control.
