摘要：
The leaching of terbuthylazine and atrazine was studied through laboratory soil columns using little to moderately carbonated soils and with fine texture. Mobility in the three soils was greater for atrazine than terbuthylazine. This might be related to the higher water solubility of atrazine, 30 mg L-1 versus 8.5 mg L-1 for terbuthylazine, and to the smaller Freundlich adsorbtion coefficient of atrazine, from 0.96 to 1.22 depending on the soil, compared with 1.88 to 2.33 for terbuthylazine. No significant difference in mobility was observed between the three soils.
