Figure 4−37. Comparison of recovery of Terbacil in stream−water matrix spikes analyzed by schedule 2060 and schedule 2437. Solid horizonal lines in the graphs aremedian values; dashed horizontal lines are the 25th and 75th percentile values. Recoveries greater or less than the y−axis limits are plotted at the axis limits.N, number of values; IQR, interquartile range (75th percentile minus 25th percentile); <, less than; >, greater than.
