- other: no data
- Conc.:
- ca. 0.003 µg/L
- Details on results:
- Beside the 53 compounds of health concern which were specifically surveyed, many other compounds were identified (tentatively or confirmed). Among these Cyclopentanone was identified in the combined solvent extract from a concentrate of DW sampled in January 1976 in New-Orleans (Louisiana). This sample contained a total of 249 compounds.
The semi-quantitative estimation of the concentration by the relative size of the peak towards an internal standard (hexaethylbenzene) allowed to estimate the concentration around 3 ng/L.
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.
