Simple estimation of effect factors for toxicity used for screening LCA

image of Simple estimation of effect factors for toxicity used for screening LCA

The approach of this project was based on the assumption that relevant toxicity data can be extracted from the risk-phrases that have been assigned to the chemical substances and published on official and advisory lists, and that this information can be transformed into one figure representing the level of toxicity. The overall purpose of this project was to facilitate the integration of the assessment of chemical substances in Life Cycle Assessment. This is put into practice by the following tasks: Establish a database with data on human toxicity and ecotoxicity for chemical substances derived from risk-phrases. Establish a software that can calculate effect factors according to the EDIP Methodology from these data. It was furthermore the purpose to apply this model to calculate effect factors for substances present on official – and advisory lists.



How to use

The Effect Factor Calculator can be started by opening the file Eff_factor.mdb. To operate this calculator you need the database programme MS Access 2000 or a later version, and you must have a status on the applied computer that allows you to execute macros and the file should NOT have the attribute “Read only” (Danish: “Skriveskyttet”). When you open the file this screen will appear and allow you to calculate effect factors based on risk-phrases or individually supplied data
