An aerobic soil biodegradation study was conducted with strychnine alkaloid to evaluate loss of the parent compound (non-radiolabeled) from sandy loam and sandy clay loam soils during 2 months of incubation, and to detect non-volatile products which occurred during this period. The biologically active soil samples were treated with the strychnine alkaloid to yield an overall concentration of 10 ppm. The treated samples and controls were held in an environmental chamber under dark conditions at a temperature of 25°C and a soil moisture content of 75% of field capacity. Eight sampling periods were chosen; at each time interval, three treated samples and a control were selected for strychnine extraction and analysis using high performance liquid chromatography (HPLC/u.v.) at a wavelength of 254 nm.
