Compilation of chemical indicators — Development, revision and additional analyses
This methodology paper aims to give a comprehensive description of the way chemical indicators have been developed by Eurostat. It explains the compilation process of the indicators on: ‘Production of toxic chemicals’, ‘Production of environmentally harmful chemicals’, as well as the two related ‘consumption’ indicators.
This methodology paper focuses on the first of these indicators, ‘Production of toxic chemicals’ and explains the methodological adaptations and revisions of the indicators that became necessary due to:
the enlargement of the EU, most recently from EU-27 to EU-28 with the accession of Croatia, changes in the PRODCOM list, and changes in the hazard classification of chemical substances, triggered by the introduction of Regulation (EC) No 1272/2008 on classification, labelling and packaging of substances and mixtures (CLP Regulation), which form the basis of an assignment to a toxicity class.
The paper describes the approaches for dealing with these changes. In addition, the paper discusses the results obtained before and after implementing these changes. Specifically, results obtained with the old system of hazard classification (risk phrases according to Directive 67/548/EEC) are compared with those obtained with the new system (hazard statements according to the CLP Regulation). These comparisons show that the changes observed are not due to differences between risk phrases and hazard statements. Rather, the use of the Classification & Labelling Inventory (also established under the CLP Regulation) allowed the extraction of more up-to-date hazard classifications with a defined methodology. Overall, this revision leads to more robust hazard information compared to the old approach. [+]
