Fig. 5. The average fraction (FC) of complexed napropamide within the specified range of molecular weights is plotted for each effluent sample from the soil with sewage sludge applied (SS). The fraction of complexed napropamide is 1 for each effluent sample but the total amount of complexed napropamide is different for each sample. Therefore, the fraction of napropamide complexed with a molecular weight between 500 and 1000 Daltons is similar for the 165- and 225-mL samples but the total amount of complex is lower for the 225-mL sample than the 165-mL sample.
