Applicant's summary and conclusion
- Executive summary:
Samples of water from a highly polluted river in Japan taken around 1980 were found to contain between 2 and 4ppm of ethanol. Because this data is quite old, it is unclear if it has any relevance to current levels of ethanol in the aquatic environment.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
