Fig. 7. 17ß-Estradiol dissipation in (A) nonsterile soil amended with nonsterile manure, (B) nonsterile soil amended with sterilized manure, (C) sterilized soil amended with nonsterile manure, and (D) sterilized soil amended with sterilized manure. All experiments with loam soil incubated at 30°C. Results are shown for mineralization and total extractable radioactivity in the left panels (manured treatments are shown as open symbols, unmanured treatments as closed symbols). Each point and error bars represent the mean value of three replicate samples and corresponding standard deviation. The relative distribution of 17ß-estradiol and estrone in soil extracts is shown 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.
