The highest concentrations of Diuron and Ametryn residues detected in the water samples were 0.45 and 0.25 p/m, respectively. The concentration of both herbicides in water decreased rapidly with time. Diuron residue was no longer detectable in water samples at the end of 16th week, while Ametryn residue took 9 weeks to fall below the detection limit. The highest concentrations of Diuron and Ametryn residue in the sediment were 5.80 and 1.13 p/m. The concentrations of Diuron and Ametryn residue in the sediment at the end of this investigation were 0.20 and 0.14 p/m, respectively. The total quantity of Diuron and Ametryn losses during the course of this experiment was estimated to be 7.7 and 5.6%, respectively, of the total application.}, number={2}, journal={The Journal of Agriculture of the University of Puerto Rico}, author={Liu, Lii-Chyuan and Fernández-Horta, Delia and Santiago-Córdova, Miguel}, year={1985}, month={Apr.}, pages={177–183} }
