Results and discussion
Any other information on results incl. tables
The solute dispersion experiment showed that the analysis of quinoline transport and retardation could be based on the assumption of negligible quinoline dispersion.
pH was important for the breakthrough of quinoline, hence at pH 7.0, the breakthrough was faster than at pH 4.6.
The retardation factors obtained were : 9.4 (at pH 4.6, thin layer); 6.9 (pH 4.6, thick layer); 6.4 (pH 7.0, thin layer) and 4.5 (pH 7.0, thick layer). The retardation factor represents the delay in breakthrough of the solute (quinoline) relative to the breakthrough of a nonretarded solute.
These values show that quinoline is mobile in soils.
At the same time, the biodegradation in the columns was determined.
Compared with the initial quinoline added, it was found that for the thin and thick layers 72 and 65% of quinoline was retained (or missing) in the column at pH 4.6 and 23% and 49% at pH 7.0. Quinoline was transformed during transport. Small amounts of 2 -OH-quinoline were detected in the experiments at 20h.
At the end of the experiments, no quinoline, 2 -OH quinoline or other products could be detected in the soil columns, so it was assumed that quinoline was mineralized at both pH.
Applicant's summary and conclusion
- Conclusions:
- Quinoline is mobile in soils and is mineralized quickly.
- Executive summary:
A soil column experiment was performed with quinoline (50 mg/kg soil) at pH 7.0 and 4.6. Transport and biodegradation were evaluated for 7.5 days.
Quinoline is mobile in the soil and is quickly mineralized.
