Fate Release of the notified polymer during application of the formulated product is expected to be small due to the efficient nature of industrial roller coating processes. Any paint residues and spilled paint are likely to cure and be disposed of into landfill. If sent to landfill leaching will be very slow since the polymer will be incorporated in a crosslinked matrix. Instead it will be subject to the slow abiotic and biotic degradation processes operative in landfills. If incinerated in a furnace the notified material will be destroyed with production of water vapour and oxides of carbon. Almost all the notified material will eventually be released as a consequence of disposal of the used food cans. These are likely to be placed into landfill or recycled for metal recovery. The notified material which is lost during reformulation and application will be disposed of into landfill or incinerated. If sent to landfill, since the material is likely to be incorporated within a crosslinked matrix with other waste polymers, leaching is likely to be very slow and the polymer will be subject to the slow abiotic and biotic degradation processes operative in landfills. If incinerated in a furnace the notified material will be destroyed with production of water vapour and oxides of carbon. After the food cans have been used they will be either disposed of into landfill or perhaps recycled for metal recovery. If placed into landfill the coating incorporating the notified polymer is likely to be slowly degraded and destroyed as described above, while if sent for recycling the polymers will be destroyed via incineration. 8. EVALUATION OF TOXICOLOGICAL DATA No toxicology data were provided, which is acceptable for polymers of NAMW greater than 1 000 according to the Act. 9. ASSESSMENT OF ENVIRONMENTAL EFFECTS No ecotoxicology data were provided, which is acceptable for polymers of NAMW greater than 1000 according to the Act. Data on the monomer constituents, together with the high molecular weight and water insolubility of the polymer, provides substantial assurance of the likely low toxicological hazard presented by the notified chemical 10. ASSESSMENT OF ENVIRONMENTAL HAZARD The environmental hazard from the notified polymer is considered to be low. Only small quantities of the notified polymer are likely to be released during reformulation activity, and in the manufacture of the specialised can coating containing the material. The essentially hydrophobic nature of the polymer is such
