HERA Comments
 The key changes versus the previous version include the following: - For more clarity, the report has been split into two parts in order to cover separately homo-polymers (P-AA, Part I) and co-polymers of (P-AA/MA, Part II). - The refined assessment has been based on updated tonnages of polycarboxylates used in detergents (EU data 2011 collected in 2012). - New experimental data have been generated and included in order to: o address the sorption behaviour (adsorption study using radio-labelled materials performed) o refine the effect assessment (new terrestrial studies performed). - The new reports include more detailed explanations than the previous version, including re-assessment of the whole available dataset. On that basis new risk characterisation ratios have been calculated for both types of polymers.
