### Results for Radishes Grown after Maturity in Soil Contaminated with Anthracene  
Table 3 shows the detailed results of the experiment (P4) in which rachishes were grown in AN-contaminated soil after maturity. The conditions included an average outdoor air temperature of 25.3 \({}^{\circ}\)C during the growing period, with AN not added at the time of sowing, and a suspension of AN sprinkled around the roots of the rachishes 27 days after sowing. The concentration in the soil was the highest 4 days after the application of AN (31 days after sowing), at 22,100 ng/g-ww, and it was the lowest 11 days after the application of AN (38 days after sowing), at 5670 ng/g-ww. Although there were some fluctuations due to AN suspensions of differing content being sprinkled around the roots, the concentration generally showed a decreasing trend. \begin{table}

Blank cells indicate that there was no measurement at this point in time. AN concentrations and weights were determined for each part of a plant for root, stem, and leaf samples. “Radish” denotes measured AN data for the whole plant; the concentration was multiplied by the weight for each part, the products added together, and the total divided by the sum of the weight. The upper numerical data in each cell are concentrations (ng/g-ww); the middle numerical data in the parentheses are masses (g); the lower values with asterisks (*) are the numbers of radish samples measured. The upper values for root, stem, and leaf measurements are concentrations (ng/g-ww); the lower values in the parentheses are masses (g).

Table 2: AN concentration in soil and rachishes in experiments under growth in contaminated soil from sowing onward. Similar to the concentration in the soil, the concentration in the radishes tended to decrease over time following the addition of AN, with the highest concentration observed 4 days after the application of AN, at 2270 ng/g-ww, and the lowest concentration observed 24 days after the application of AN, at 342 ng/g-ww. The trends in concentration differed according to the part of the radish examined. The concentration in the roots and stems was the highest 1 day after the application of AN, at 3470 ng/g-ww and 230 ng/g-ww, respectively.
