摘要：

A comprehensive study comparing measurements of napropamide pesticide adsorption from two different methods, batch equilibrium and column flow-through methods, is reported. Thirty-six undisturbed soil columns were removed from a 0. 6-ha field for the laboratory flow study, while 36 soil samples were taken from the sides of the holes formed by the columns for batch equilibrium adsorption measurements. Column measurements of the adsorption distribution coefficient, K//D were inferred from breakthrough curves of chloride and napropamide. The field mean estimates of K//D from the batch and column measurements were similar but individual measurements were kuncorrelated. Furthermore, no correlations were found between either K//D measurements and soil organic carbon fraction measurements.
