ENVIRONMENTAL EXPOSURE Release The notified polymer will be compounded into hairspray products in at three major cities and is expected to be sold Australia-wide providing a wide exposure of the chemical to the environment. The average per site of the commercial form of the notified polymer in ethanol (Advantage CP/Polymer ACV-4009), is expected to be 10 tonnes per annum based on the maximum estimated import quantities of 100 tonnes per annum and 10 companies likely to be involved in reformulation into hairspray products. Given the high cost of the notified polymer, reformulators are expected to minimise waste levels, with an estimated 0.5% remaining unused in the drums and 0.25% remaining as residue in the batch processing equipment. Drum residues amounting to 25 kg per year per site (50 kg total and 50% polymer) will be disposed of to landfill. Residues from the batch processing equipment amounting to 12.5 kg per year per site will be washed into the plant sewer and precipitated in the sludge of the solids separating system. The dried sludge is expected to be disposed of to landfill. The notified polymer is intended solely for use in hairspray products and, as such, would be expected to be released to the environment via consumer use through washing the residual polymer (assumed to be 100% of that applied) from the hair and into the sewerage system. It is envisaged that the notified polymer will replace existing hairspray polymers which have similar properties resulting in no net environmental effect. Due to its insoluble nature, the notified polymer is likely to be associated with the sludge/solids compartment of sewage where it is expected to be incinerated or spread onto agricultural land. If the notified polymer remains suspended in sewage water, a predicted environmental concentration (PEC) for the polymer in sewage water throughout Australia can be estimated from the assumptions, 100 tonnes maximum annual production, an Australian population of 17 million and a daily per capita water usage volume of 150 L. This provides a PEC of 0.1 ppm in sewage water which would be swiftly reduced to insignificant levels (likely to be below 10 ppb) by precipitation or dilution in rivers, lakes and oceans which act
