Results and discussion

Any other information on results incl. tables

A maximum of 2.8% of the total radioactivity applied to soil desorbed or leached into water; DCA recovered from water decreased from 12 to 1% of the total radioactivity inwater between 1 and 30 days after flooding; between 10.5 and 18.5% of the radioactivity remaining in soil at hte end of the experiments was extractable; of the radioactivity recovered, between 5 and 11% was DCA, and up to 6 to 19% was 3,3',4,4'-tetrachloroazobenzene (TCAB), these percentages being dependent on exposure time; rice accumulated 0.5% or less of the total radioactivity in soil; only 35 to 55% of the accumulated radioactivity was extractable; very small amounts of radioactivity were accumulated by aquatic organisms;
