migrated dataset

In a laboratory experiment, the distribution of 14C-labelled 3,4-DCA in the sediment/water system was examined. 3 sediments collected from a creek, a pond and a drainage ditch of a fruitgrowing plantation were tested. Radioactivity left in the water phase was 21.8% (after 8 days) in the creek sediment, 10.4% (90 days) in the pond sediment and 1% (90 days) in the ditch sediment. The adsorption process was not finished after 28 d as the radioactivity decreased until day 90. 3,4-DCA was converted predominantly to non-extractable residues, presumably without preceding microbial transformation because no significant CO2 amounts (maximum 3.8%) could be detected (Heim et al., 1994).
