The toner will be imported in sealed cartridges at concentrations of <20% and the developer imported in 1L plastic bottles at <5% concentration. No manufacture, reformulation or repackaging will occur in Australia. Used cartridges and empty bottles may be recycled. HUMAN HEALTH RISK ASSESSMENT The notified polymer meets the PLC criteria and can therefore be considered to be of low hazard. A suspension of the notified polymer was found to be non-mutagenic in a bacterial reverse mutation study carried out using the preincubation method (OECD TG 471). Although not considered in this risk assessment, NICNAS notes that the notified polymer contains a residual monomer that is classified as hazardous according to the Globally Harmonised System of as adopted for industrial chemicals in Australia. Classification and Labelling of Chemicals (GHS), This is not present in the notified polymer as introduced above the cut off concentration for classification. The risk of the notified polymer to occupational and public health is not considered to be unreasonable given the assumed low hazard and the assessed use pattern.
