ANNEX 9
Page 2
.1 Acute Aquatic Toxicity Data
The test procedures for aquatic toxicity such as OECD 203, its ISO or other equivalents, should be used for soluble substances. For substances of low solubility, Annex 9 of IMO GESAMP Reports and Studies No. 35 should be followed. A marine or fresh water crustacean is considered to be suitable for such testing purposes (e.g., Daphnia magna, Mysidopsis bahia, Chaetogammarus marinus and Acartia tonsa ). Existing data on fish or crustaceans would be acceptable for assessment.
.2 Biodegradability Data
The preferred test is a 28 day ready biodegradability test similar to OECD 301A to E, its ISO or other equivalents. _
.3 The Log Octanol Water Partition Coefficient
This coefficient (Log Pow) is a predictive measure of the tendency of a substance to accumulate in the fatty tissues of an organism. It can be measured using OECD Guidelines 107 or 117, its ISO or other equivalents, or alternatively it can be calculated using fragmental constants (QSAR). If available, measured bioconcentration data are preferred,
3 If active ingredients include substances in pollution category B, C, D or appendix III (according to the IBC Code, GESAMP Hazard Profile or provisional assessment) the component would be acceptable. Unevaluated components would be acceptable, provided the acute toxicity is > 1mg/l.
4 Components that are considered either Annex I or petrochemical complex mixtures of hydrocarbons will be evaluated using the procedure outlined in MEPC/Circ.265, based on the provisional assessment of hydrocarbon families.
5 The following procedures for submission of new cleaning additives are applicable:
.1 Data on products to be evaluated by IMO should be made available to the national Administration involved, by means of the accompanying form.
.2 The component names used on the form shall be the correct technical names, which means that trade names are not acceptable. Any trade named components must have their ingredients and their proportions fully specified.
.3 The data shall be submitted at a period prior to the relevant IMO meeting, which is acceptable to the national Administration involved.
.4 Incomplete data will not be taken into consideration.
.5 All proprietary data will be treated as confidential by the national Administrations and their representatives, which form the evaluating group.
.6 Any changes in names, composition or otherwise of any product which has passed the evaluation of IMO at an earlier occasion, shall be reported to the national Administration .
