Fig. 5. Effect of temperature on the dissipation of [4–¹⁴C]-testosterone in loam soil with or without amendment with swine manure slurry (10% v/w). Total extractable radioactivity and mineralization are indicated in the left panels (unmanured soils with closed symbols, manured soils with open symbols). Each point and error bars represent the mean value of three replicate samples and corresponding standard deviation. The distributions of extractable radioactivity in parent compound and transformation products resolved by high performance liquid chromatography (HPLC)–radioactivity detection (RD) are indicated in the right panels. The height of the total bars corresponds to total extractable radioactivity and the height for each compound is the mean value of three replicate measurements.
