Results and discussion

Migrated dataset;
RS-Freetext:
Overall, there was a higher microbial respiration rate for soil with higher organic carbon content. Control soils of both types showed a gradual decline in CO2 efflux over the 7-d incubation period.
cis and trans 1,4-dichloro-2-butene depressed respiration at 1000 µg/g in sandy loam and remained significantly depressed for all days and for day 6. Only the results for trans 1,4-dichloro-2-butene in the silt loam indicate that a depression occurred during the experiment but disappeared by the final day.
In further toxicity tests it was established that the isomers could be added to the two soils at 500 µg/g without irreversibly suppressing microbial respiration
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.
