Box plots of K d values for sulfonamides and macrolides reported in literature. The sulfonamides (left) include sulfamethazine and sulfachloropyridazine, and the macrolides (right) includes tylosin and erythromycin. pH values range from 5.2-7.5 when reported. Soil types include loamy and sandy loam, clay loam, loam, loamy sand, and silt loam. The high variation of Kd values found in literature is illustrated here. The upper and lower boundaries of the box represent the 75th and 25th percentile respectively. The middle line indicates the median value, and the whiskers indicate the maximum and minimum values.
