to give an environment release of 46 ppb. This is more than orders of magnitude below the EC50 for daphnia. It is likely that most of the polymer will be in the solid waste, at the tannery or the sewage treatment works, with little in the waste water. The actual release is expected to be significantly less than 46 ppb as a result of incorporation in the solid wastes. Due to the molecular weight of the polymer it is not expected to bioaccumulate and will biologically degrade, thus it will not build up in the environment. The Environmental hazard of Aqualen Top D2012 and the polymer is expected to be low due and with the small quantities to be imported it will not present an environment hazard. ASSESSMENT OF PUBLIC AND OCCUPATIONAL HEALTH AND SAFETY EFFECTS There is no information on the effect of Aqualen Top D2012 on human exposure. Based on the results of animals studies on a similar polymer (Melio Promul 68), the notified polymer may have low acute oral toxicity. Aqualen Top has low vapour pressure is not explosive is not flammable and is non-reactive under normal use conditions. The maximum exposure of each worker to the notified polymer is one hour a day during preparation of the finish coat and quality control checks. The application of the finish coat is carried out in an enclosed booth or under positive ventilation. Under normal use conditions, given the physico-chemical profile of the notified chemical together with the engineering controls, this exposure is unlikely to result in any adverse health effects. The public is unlikely to be exposed to the notified polymer during importation and transport to tanneries. However, the public may have contact with the polymer, when it is used as a component in leather surface coatings.
