Wholesale workers are not expected to encounter exposure to the notified polymer during packing and handling of ink bottles containing the notified polymer in ink formulations except in case of an accident. Overall, the notified polymer is not anticipated to lead to an unacceptable risk to workers in industrial printing operations. 6.3.2. Public health Neither the inks containing the notified polymer nor substrates containing the cured ink will be sold to the public. Therefore, the risk to public health is not expected based on the low potential for exposure. 7. ENVIRONMENTAL IMPLICATIONS 7.1. Environmental Exposure & Fate Assessment 7.1.1 Environmental Exposure The notified polymer will not be manufactured or reformulated within . Therefore, release may only occur during a transport accident and handling of the imported formulated products, and as such is not expected to be significant. Some release is expected to occur during the printing process via cleaning and maintenance operations and small spills. It is expected these residues will be disposed of to landfill. The formulated products containing the notified polymer will be applied to a variety of substrates including paper materials using industrial inkjet printers. The applied notified polymer is expected to be trapped in the ink matrix with other components of the ink. The majority of the notified polymer is expected to be disposed of to landfill and is expected to remain associated with the substrate to which it has been applied. Of the notified polymer applied to paper, 50% is expected to be recycled. During recycling processes, waste paper is repulped using a variety of chemical agents which, amongst other things, enhance detachment of toner from the fibres. 7.1.2 Environmental fate The results of a biodegradability study on the notified polymer submitted, indicated that the polymer is not readily biodegradable. Refer to Appendix B for details of this study. The small amount of notified polymer washed to the sewers as a result of paper recycling is expected to be removed in sewage treatment plants by adsorption to solids based on its estimated high log Pow values, low water solubility and high molecular weight (MW > 1000). In landfill the notified polymer is expected to degrade slowly via biotic and abiotic processes over time to form predominantly simple organic compounds and water. Leaching of the notified polymer into water is not likely due to its expected low water solubility and high adsorption/desorption coefficient. 7.1.3 Predicted Environmental Concentration (PEC)
