Results and discussion
Any other information on results incl. tables
BUA report:
A) Investigations in the Hydrosphere
In 18 test series DOC, COD or o-chloroaniline concentration under aerobic conditions were determined in filtrate, i.e. these tests record elimination both by degradation and by adsorption and chemical binding. In 14 of the 18 test series, elimination was between 14% in 28 days and 98% in 4.8 days. In the remaining 4 test series elimination was 0% in 28 and 35 days, respectively.
Overall, the results of the degradation studies with o-chloroaniline indicate that for this compound elimination by sorption plays a not insignificant role.
B) Investigations in the Geosphere
Under aerobic conditions most of the o-chloroaniline released into the soil is bound covalently to soil particles. After 16 weeks approx. 64% of the o-chloroaniline was bound in gley with a very humus content. In anaerobic soil zones, o-chloroaniline is neither bound chemically to a large extent nor degraded biologically. In eight months the concentration of free o-chloroaniline decreased by less than 10%. o-Chloroaniline can be expected to have a pH-dependent and partly oxygen-dependent overall moderate tendency to sorption (physi- and chemisorption) in soil. The lower the pH and the higher the oxygen content, the stronger the sorption. Concentration-dependent transport of o-chloroaniline in soil via leachate into the ground wter appears to be possible, particularly at high pH levels and under anaerobic conditions. it is not possible to estimate the extent to which this transport occurs, but it is presumably low.
Applicant's summary and conclusion
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
