ASSESSMENT OF ENVIRONMENTAL EFFECTS Although ecotoxicity data are not required for chemicals imported in quantities less than 1 the following ecotoxicity studies have been supplied on Lodyne S-106A by the notifier. The tests were carried out according to OECD Test Methods.

No data have been provided for the toxicity of the notified polymer to algae. As polymers containing quaternary functionalities are known to be around 6 times more toxic to algae than to fish (13), this would be required should the import of the notified chemical exceed 1 tonne. The notified chemical was soluble in water at all concentrations tested. No observations of sub-lethal effects were recorded during the ecotoxicity studies. Additionally, the following ecotoxicity data appears on the Material Safety Data Sheet (MSDS) for the product, Lodyne S-152B. The reports for these data were not provided.
